FIELD OF THE INVENTION

The present invention relates to stabilization of non-subtilisin enzymes in liquid detergent compositions.

BACKGROUND

WO 98/13458, WO 94/04651 , WO 98/13460, WO 95/25791 , and WO 2009/1 18375 disclose liquid detergents with a subtilisin-type protease stabilized by a peptide aldehyde. WO 201 1/036153 discloses that the addition of a peptide aldehyde to a particulate subtilisin- containing detergent can improve the detergency.

It is well known that aldehydes can form soluble adducts with NaHS0 ₃ (bisulfite or hydrosulfite adducts) and that peptide aldehydes tend to be sparingly water soluble. Peptide aldehyde hydrosulfite adducts, and their use in detergents, are disclosed in WO 2013/004636.

WO 98/47523 and US 6,500,802 disclose peptidyl-2-amino-1 -hydroxyalkanesulfonic acids and their use as protease inhibitors. US 5,436,229 discloses bisulfite adducts of L-Arginine aldehyde derivatives and their use as thrombin inhibitors.

US 4,703,036, US 4,478,745 and US 5,578,574 disclose methods of preparing peptide aldehydes in dry form. SUMMARY

The inventors have found that incorporation of a subtilisin inhibitor above a certain concentration into a liquid detergent improves the storage stability of non-subtilisin enzymes more than the storage stability of subtilisins.

Accordingly, the invention provides a method for improving the storage stability of a non- subtilisin enzyme in a liquid detergent composition containing a subtilisin and a non-subtilisin, comprising preparing a liquid detergent composition containing a subtilisin, a non-subtilisin, and more than a concentration C of a subtilisin inhibitor; wherein C is determined as the

concentration of inhibitor where the relative residual activity of the subtilisin is increased by 25% of the increase from no inhibitor to C, when the concentration of the subtilisin inhibitor is increased from C to two times C, after incubation for one week at 40°C in Detergent M.

In an embodiment, the relative storage stability improvement of the non-subtilisin is higher than the relative storage stability improvement of the subtilisin. Other aspects and embodiments of the invention are apparent from the description and examples.

DETAILED DESCRIPTION

We have found that the level of protease inhibitors needed for improving the stability of non-protease enzymes (like amylase, lipase, cellulase, and other detergent enzymes) is higher than for securing the stability of protease enzymes; and the stabilizing effect of a second addition of inhibitor on top of a first addition of inhibitor is higher on non-protease enzymes than on proteases. Hence by adding protease inhibitor to the individual non-protease enzyme products will lead to a more optimal inhibitor dosing for improving stability of the whole enzyme composition, and is easier and more convenient for a detergent manufacturer, than having to choose proteases with different inhibitor levels depending on the choice and inclusion rate of non-protease enzymes. Moreover the inhibitor doses will be "automatically adjusted" to the desired level.

The present invention relates to a detergent composition comprising a subtilisin, a non- subtilisin and a subtilisin inhibitor; in which the subtilisin inhibitor concentrations are above a certain concentration C. The first inhibitor addition (concentration C) primarily increases protease stability, whereas when the inhibitor concentration is above C, additional inhibitor addition will have a more pronounced effect on the stability of the non-protease enzyme than on the protease enzyme; and hence beneficially could be added together with the non-protease enzyme, as part of a non-protease product. The present invention thus also relates to a liquid composition comprising a non-protease enzyme and a protease inhibitor, and the method of using this for increasing stability of a multi enzyme solution in a protease containing liquid detergent, which may or may not already contain protease inhibitors.

Definitions

Inhibitor concentration C

An inhibitor concentration C is defined, so that when the inhibitor concentration is doubled from a concentration of C to a concentration of 2C (i.e., 2C = 2 x C), the residual protease activity increases ("residual protease activity at 2C" - "residual protease activity at C") by 25% of the residual protease activity increase from no inhibitor to C ("residual protease activity at C" -

"residual activity at no inhibitor"). "No inhibitor" means that the concentration of inhibitor is zero.

The test system to determine "dose 1 " (C) and "dose 2" (2C) is described in Example 1. A model detergent system is used (detergent A) and protease, lipase, and different concentrations of protease inhibitor are added (detergent M). Residual protease activity is determined by comparing activity after storage for 1 week at 40°C with 1 week at -18°C. The data are used to prepare a dose response curve which is used to identify the inhibitor concentration C. Inhibitor concentrations are given in molar ratios and mg/L relative to the test system in Example 1 and mg/L will be similarly increased if the protease concentration is increased.

Compositions of the present invention can thus be described as detergent compositions with protease and non-protease enzymes having more than "dose 1 " protease inhibitor (C); where

("residual protease activity at dose 2" — "residual protease activity at dose 1") ^ ("residual protease activity at dose 1" — "residual protease activity at no inhibitor")

; and "dose 2" = 2 x "dose 1 ".

Subtilisin

The subtilisin enzymes for use in the present invention include those of bacterial, fungal, plant, viral or animal origin e.g. vegetable or microbial origin. Microbial origin is preferred.

Chemically modified or protein engineered mutants are included.

In the context of the present invention, the subtilisin enzyme family (EC 3.4.21 .62) shall be understood as described by Siezen et al., Protein Engng. 4 (1991 ) 719-737 and Siezen et al. Protein Science 6 (1997) 501 -523. As described therein, the subtilisin family may be divided into 3 sub-groups, i.e. I-S1 ("true" subtilisins), I-S2 (highly alkaline proteases) and intracellular subtilisins.

Examples of subtilisins are those derived from Bacillus such as subtilisin lentus, Bacillus lentus, subtilisin Novo, subtilisin Carlsberg, Bacillus licheniformis, subtilisin BPN', subtilisin 309, subtilisin 147 and subtilisin 168 described in WO 89/06279 and protease PD138 (WO

93/18140). Additional examples are described in WO 98/0201 15, WO 01/44452, WO 01/58275, WO 01/58276, WO 03/006602 and WO 04/099401.

Examples of useful variants are described in WO 92/19729, WO 98/201 15, WO 98/201 16, and WO 98/34946, especially the variants with substitutions in one or more of the following positions: 3, 4, 9, 15, 27, 36, 57, 68, 76, 87, 95, 96, 97, 98, 99, 100, 101 , 102, 103, 104, 106, 1 18, 120, 123, 128, 129, 130, 160, 167, 170, 194, 195, 199, 205, 206, 217, 218, 222, 224, 232, 235, 236, 245, 248, 252 and 274 using the BPN' numbering. More preferred the subtilase variants may comprise the mutations: S3T, V4I, S9R, A15T, K27R, ^* 36D, V68A, N76D, N87S,R, ^* 97E, A98S, S99G,D,A, S99AD, S101 G,M,R S103A, V104I,Y,N, S106A, G1 18V,R, H120D,N, N123S, S128L, P129Q, S130A, G160D, Y167A, R170S, A194P, G195E, V199M, V205I, L217D, N218D, M222S, A232V, K235L, Q236H, Q245R, N252K, T274A (using BPN' numbering).

Examples of commercially available subtilisins include Kannase™, Everlase™,

Primase™, Duralase™, Esperase™, Alcalase™, Durazym™, Savinase™, Ovozyme™,

Liquanase™, Coronase™, Polarzyme™, Pyrase™, and Clear-Lens™ Pro; Blaze™ (Novozymes A/S). Other commercially available proteases include Ronozyme™ Pro, Maxatase™, Maxacal™, Maxapem™, Opticlean™, Properase™, Purafect™, Purafect Ox™, Purafact Prime™, Excellase™, FN2™, FN3™ and FN4™ (available from Dupont).

In an embodiment of the invention, the subtilisin is subtilisin 309 or subtilisin BPN', or a variant of any of these. Preferably, the amino acid sequence of the subtilisin has at least 60% sequence identity, preferably at least 70%, more preferably at least 80%, more preferably at least 90%, more preferably at least 95%, 96%, 97%, 98%, 99%, and most preferably 100% sequence identity to the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2.

In an embodiment, the number of amino acid substitutions, deletions and/or insertions introduced into the amino acid sequence of SEQ ID NO: 1 or SEQ ID NO: 2 is up to 10, e.g., 1 , 2, 3, 4, 5, 6, 7, 8, 9, or 10; or up to 5, e.g., 1 , 2, 3, 4, or 5. The amino acid changes may be of a minor nature, that is conservative amino acid substitutions or insertions that do not significantly affect the folding and/or activity of the protein; small deletions, typically of 1 -30 amino acids; small amino- or carboxyl-terminal extensions, such as an amino-terminal methionine residue; a small linker peptide of up to 20-25 residues; or a small extension that facilitates purification by changing net charge or another function, such as a poly-histidine tract, an antigenic epitope or a binding domain.

Examples of conservative substitutions are within the groups of basic amino acids

(arginine, lysine and histidine), acidic amino acids (glutamic acid and aspartic acid), polar amino acids (glutamine and asparagine), hydrophobic amino acids (leucine, isoleucine and valine), aromatic amino acids (phenylalanine, tryptophan and tyrosine), and small amino acids (glycine, alanine, serine, threonine and methionine). Amino acid substitutions that do not generally alter specific activity are known in the art and are described, for example, by H. Neurath and R.L. Hill, 1979, In, The Proteins, Academic Press, New York. Common substitutions are Ala/Ser, Val/lle, Asp/Glu, Thr/Ser, Ala/Gly, Ala/Thr, Ser/Asn, Ala/Val, Ser/Gly, Tyr/Phe, Ala/Pro, Lys/Arg, Asp/Asn, Leu/lle, LeuA al, Ala/Glu, and Asp/Gly.

Essential amino acids in a polypeptide can be identified according to procedures known in the art, such as site-directed mutagenesis or alanine-scanning mutagenesis (Cunningham and Wells, 1989, Science 244: 1081 -1085). In the latter technique, single alanine mutations are introduced at every residue in the molecule, and the resultant mutant molecules are tested for subtilisin activity to identify amino acid residues that are critical to the activity of the molecule. See also, Hilton et al., 1996, J. Biol. Chem. 271 : 4699-4708. The active site of the subtilisin or other biological interaction can also be determined by physical analysis of structure, as determined by such techniques as nuclear magnetic resonance, crystallography, electron diffraction, or photoaffinity labeling, in conjunction with mutation of putative contact site amino acids. See, for example, de Vos et al., 1992, Science 255: 306-312; Smith et al., 1992, J. Mol. Biol. 224: 899-904; Wlodaver ei a/., 1992, FEBS Lett. 309: 59-64. The identity of essential amino acids can also be inferred from an alignment with a related polypeptide. Single or multiple amino acid substitutions, deletions, and/or insertions can be made and tested using known methods of mutagenesis, recombination, and/or shuffling, followed by a relevant screening procedure, such as those disclosed by Reidhaar-Olson and Sauer, 1988, Science 241 : 53-57; Bowie and Sauer, 1989, Proc. Natl. Acad. Sci. USA 86: 2152-2156;

WO 95/17413; or WO 95/22625. Other methods that can be used include error-prone PCR, phage display (e.g., Lowman et al., 1991 , Biochemistry 30: 10832-10837; U.S. Patent No. 5,223,409; WO 92/06204), and region-directed mutagenesis (Derbyshire et al., 1986, Gene 46: 145; Ner ei a/., 1988, DNA 7: 127).

The relatedness between two amino acid sequences is described by the parameter "sequence identity". For purposes of the present invention, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the

EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276-277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled "longest identity" (obtained using the -nobrief option) is used as the percent identity and is calculated as follows: (Identical Residues x 100)/(Length of Alignment - Total Number of Gaps in Alignment).

The methods and compositions of the invention may include 1 , 2, 3, 4, 5, 6, 7, or 8 non- subtilisin enzyme(s). A non-subtilisin enzyme is an enzyme, preferably a detergent enzyme, which is not a subtilisin.

Liquid detergent composition

The liquid detergent composition has a physical form, which is not solid (or gas). It may be a pourable liquid, a pourable gel or a non-pourable gel. It may be either isotropic or structured, preferably isotropic. It may be a formulation useful for washing in automatic washing machines or for hand washing.

The liquid detergent composition may be aqueous, typically containing at least 20% by weight and up to 95% water, such as up to 70% water, up to 50% water, up to 40% water, up to 30% water, or up to 20% water. Other types of liquids, including without limitation, alkanols, amines, diols, ethers and polyols may be included in an aqueous liquid detergent. An aqueous liquid detergent may contain from 0-30% organic solvent. A liquid detergent may even be nonaqueous, wherein the water content is below 10%, preferably below 5%.

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.

The detergent composition may take the form of a unit dose product. A unit dose product is the packaging of a single dose in a non-reusable container. It is increasingly used in detergents for laundry and dish wash. A detergent unit dose product is the packaging (e.g., in a pouch made from a water soluble film) of the amount of detergent used for a single wash.

Pouches can be of any form, shape and material which is suitable for holding the composition, e.g., without allowing the release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch. Preferred films are polymeric materials preferably polymers which are formed into a film or sheet. Preferred polymers, copolymers or derivates thereof are selected polyacrylates, and water soluble acrylate copolymers, methyl cellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, malto dextrin, poly methacrylates, most preferably polyvinyl alcohol copolymers and, hydroxypropyl methyl cellulose (HPMC). Preferably the level of polymer in the film for example PVA is at least about 60%. Preferred average molecular weight will typically be about 20,000 to about 150,000. Films can also be a blend compositions comprising hydrolytically degradable and water soluble polymer blends such as polyactide and polyvinyl alcohol (known under the Trade reference M8630 as sold by Chris Craft In. Prod. Of Gary, Ind., US) plus plasticizers like glycerol, ethylene glycerol, Propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry cleaning composition or part components and/or a liquid cleaning composition or part components separated by the water soluble film. The compartment for liquid components can be different in composition than compartments containing solids (see e.g., US 2009/001 1970).

The choice of detergent components may include, for textile care, the consideration of the type of textile to be cleaned, the type and/or degree of soiling, the temperature at which cleaning is to take place, and the formulation of the detergent product. Although components mentioned below are categorized by general header according to a particular functionality, this is not to be construed as a limitation, as a component may comprise additional functionalities as will be appreciated by the skilled artisan.

The choice of additional components is within the skill of the artisan and includes conventional ingredients, including the exemplary non-limiting components set forth below. Surfactants

Hydrotropes

A hydrotrope is a compound that solubilises hydrophobic compounds in aqueous solutions

(or oppositely, polar substances in a non-polar environment). Typically, hydrotropes have both hydrophilic and a hydrophobic character (so-called amphiphilic properties as known from surfactants); however the molecular structure of hydrotropes generally do not favor

spontaneous self-aggregation, see for example review by Hodgdon and Kaler (2007), Current Opinion in Colloid & Interface Science 12: 121 -128. Hydrotropes do not display a critical concentration above which self-aggregation occurs as found for surfactants and lipids forming miceller, lamellar or other well defined meso-phases. Instead, many hydrotropes show a continuous-type aggregation process where the sizes of aggregates grow as concentration increases. However, many hydrotropes alter the phase behavior, stability, and colloidal properties of systems containing substances of polar and non-polar character, including mixtures of water, oil, surfactants, and polymers. Hydrotropes are classically used across industries from pharma, personal care, food, to technical applications. Use of hydrotropes in detergent compositions allow for example more concentrated formulations of surfactants (as in the process of compacting liquid detergents by removing water) without inducing undesired phenomena such as phase separation or high viscosity.

The detergent may contain 0-5% by weight, such as about 0.5 to about 5%, or about 3% to about 5%, of a hydrotrope. Any hydrotrope known in the art for use in detergents may be utilized. Non-limiting examples of hydrotropes include sodium benzene sulfonate, sodium p- toluene sulfonate (STS), sodium xylene sulfonate (SXS), sodium cumene sulfonate (SCS), sodium cymene sulfonate, amine oxides, alcohols and polyglycolethers, sodium

hydroxynaphthoate, sodium hydroxynaphthalene sulfonate, sodium ethylhexyl sulfate, and combinations thereof. Builders and Co-Builders

In a dish wash detergent, the level of builder is typically 40-65%, particularly 50-65%. The builder and/or co-builder may particularly be a chelating agent that forms water-soluble complexes with Ca and Mg ions. Any builder and/or co-builder known in the art for use in laundry detergents may be utilized. Non- limiting examples of builders include citrates, zeolites, diphosphates (pyrophosphates), triphosphates such as sodium triphosphate (STP or STPP), carbonates such as sodium carbonate, soluble silicates such as sodium metasilicate, layered silicates (e.g., SKS-6 from Hoechst), ethanolamines such as 2-aminoethan-1-ol (MEA), diethanolamine (DEA, also known as iminodiethanol), triethanolamine (TEA, also known as 2,2',2"-nitrilotriethanol), and

Suitable cellulosic polymers include anionically modified cellulose, nonionically modified cellulose, cationically modified cellulose, zwitterionically modified cellulose, and mixtures thereof. Suitable cellulosic polymers include methyl cellulose, carboxy methyl cellulose, ethyl cellulose, hydroxyl ethyl cellulose, hydroxyl propyl methyl cellulose, ester carboxy methyl cellulose, and mixtures thereof.

Anti-redeposition agents - The detergent compositions of the present invention may also include one or more anti-redeposition agents such as carboxymethylcellulose (CMC), polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), polyoxyethylene and/or polyethyleneglycol (PEG), homopolymers of acrylic acid, copolymers of acrylic acid and maleic acid, and ethoxylated polyethyleneimines. The cellulose based polymers described under soil release polymers above may also function as anti-redeposition agents.

Rheology Modifiers are structurants or thickeners, as distinct from viscosity reducing agents. The rheology modifiers are selected from the group consisting of non-polymeric crystalline, hydroxy-functional materials, polymeric rheology modifiers which impart shear thinning characteristics to the aqueous liquid matrix of the composition. The rheology and viscosity of the detergent can be modified and adjusted by methods known in the art, for example as shown in EP 2169040.

Other suitable adjunct materials include, but are not limited to, anti-shrink agents, anti- wrinkling agents, bactericides, binders, carriers, dyes, enzyme stabilizers, fabric softeners, fillers, foam regulators, hydrotropes, perfumes, pigments, sod suppressors, solvents, and structurants for liquid detergents and/or structure elasticizing agents.

Bleaching Systems

Due to the incompatibility of the components there are still only few examples of liquid detergents combining bleach and enzymes (e.g., US 5,275,753 or WO 99/00478). The detergent may contain 0-50% of a bleaching system. Any bleaching system known in the art for use in laundry detergents may be utilized. Suitable bleaching system components include bleaching catalysts, photobleaches, bleach activators, sources of hydrogen peroxide such as sodium percarbonate and sodium perborates, preformed peracids and mixtures thereof.

Suitable preformed peracids include, but are not limited to, peroxycarboxylic acids and salts, percarbonic acids and salts, perimidic acids and salts, peroxymonosulfuric acids and salts, for example, Oxone (R), and mixtures thereof. Non-limiting examples of bleaching systems include peroxide-based bleaching systems, which may comprise, for example, an inorganic salt, including alkali metal salts such as sodium salts of perborate (usually mono- or tetra-hydrate), percarbonate, persulfate, perphosphate, persilicate salts, in combination with a peracid-forming bleach activator. The term bleach activator is meant herein as a compound which reacts with peroxygen bleach like hydrogen peroxide to form a peracid. The peracid thus formed constitutes the activated bleach. Suitable bleach activators to be used herein include those belonging to the class of esters amides, imides or anhydrides. Suitable examples are tetracetylethylene diamine (TAED), sodium 4-[(3,5,5-trimethylhexanoyl)oxy]benzene sulfonate (ISONOBS), diperoxy dodecanoic acid, 4-(dodecanoyloxy)benzenesulfonate (LOBS), 4- (decanoyloxy)benzenesulfonate, 4-(decanoyloxy)benzoate (DOBS), 4-(nonanoyloxy)- benzenesulfonate (NOBS), and/or those disclosed in WO 98/17767. A particular family of bleach activators of interest was disclosed in EP624154 and particulary preferred in that family is acetyl triethyl citrate (ATC). ATC or a short chain triglyceride like triacetin has the advantage that it is environmental friendly as it eventually degrades into citric acid and alcohol.

Furthermore acetyl triethyl citrate and triacetin has a good hydrolytical stability in the product upon storage and it is an efficient bleach activator. Finally ATC provides a good building capacity to the laundry additive. Alternatively, the bleaching system may comprise peroxyacids of, for example, the amide, imide, or sulfone type. The bleaching system may also comprise peracids such as 6-(phthalimido)peroxyhexanoic acid (PAP). The bleaching system may also include a bleach catalyst. In some embodiments the bleach component may be an organic catalyst selected from the group consisting of organic catalysts having the following formulae:

and mixtures thereof; wherein each R ¹ is independently a branched alkyl group containing from 9 to 24 carbons or linear alkyl group containing from 1 1 to 24 carbons, preferably each R ¹ is independently a branched alkyl group containing from 9 to 18 carbons or linear alkyl group containing from 1 1 to 18 carbons, more preferably each R ¹ is independently selected from the group consisting of 2-propylheptyl, 2-butyloctyl, 2-pentylnonyl, 2-hexyldecyl, n-dodecyl, n- tetradecyl, n-hexadecyl, n-octadecyl, iso-nonyl, iso-decyl, iso-tridecyl and iso-pentadecyl. Other exemplary bleaching systems are described, e.g., in WO 2007/087258, WO 2007/087244, WO 2007/087259 and WO 2007/087242. Suitable photobleaches may for example be sulfonated zinc phthalocyanine.

Formulation of detergent products

The liquid detergent composition of the invention may be in any convenient form, e.g., a pouch having one or more compartments, a gel, or a regular, compact or concentrated liquid detergent (see e.g., WO 2009/098660 or WO 2010/141301 ).

Pouches can be configured as single or multi compartments. It can be of any form, shape and material which is suitable for holding the composition, e.g., without allowing release of the composition from the pouch prior to water contact. The pouch is made from water soluble film which encloses an inner volume. Said inner volume can be divided into compartments of the pouch. Preferred films are polymeric materials preferably polymers which are formed into a film or sheet. Preferred polymers, copolymers or derivates thereof are selected polyacrylates, and water soluble acrylate copolymers, methyl cellulose, carboxy methyl cellulose, sodium dextrin, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, malto dextrin, poly methacrylates, most preferably polyvinyl alcohol copolymers and, hydroxypropyl methyl cellulose (HPMC). Preferably the level of polymer in the film for example PVA is at least about 60%. Preferred average molecular weight will typically be about 20,000 to about 150,000. Films can also be of blended compositions comprising hydrolytically degradable and water soluble polymer blends such as polylactide and polyvinyl alcohol (known under the Trade reference M8630 as sold by MonoSol LLC, Indiana, USA) plus plasticisers like glycerol, ethylene glycerol, propylene glycol, sorbitol and mixtures thereof. The pouches can comprise a solid laundry cleaning composition or part components and/or a liquid cleaning composition or part components separated by the water soluble film. The compartment for liquid components can be different in composition than compartments containing solids.

Detergent ingredients can be separated physically from each other by compartments in water dissolvable pouches. Thereby negative storage interaction between components can be avoided. Different dissolution profiles of each of the compartments can also give rise to delayed dissolution of selected components in the wash solution.

Further the following detergents with protease inhibitors were prepared. The detergents were placed in closed glasses at 40°C. Residual activity of protease was measured (by comparison to a reference stored at -18°C) after 1week, using standard enzyme analytical methods

(protease measured by hydrolysis of Ν,Ν-dimethylcasein at 40°C, pH 8.3). The inhibitor levels tested relative to protease were in the range 0.5-500 molar ratio (inhibitor:protease). The data points were connected and the inhibitor dose 1 and dose 2 were determined by interpolation so that ((residual protease activity at dose 2) - (residual protease activity at dose 1 ))/ ((residual protease activity at dose 1 ) - (residual protease activity at no inhibitor)) = 0.25; and dose 2 = 2 x dose 1 .
