Field of the invention
The present invention generally relates to the field of pesticides. More specifically, the present invention relates to novel spinosyn compounds having advantageous properties, processes for their preparation, and their use as pesticides.
Background of the invention
Spinosyns are a large family of natural compounds produced through fermentation of several species of soil bacteria of the genus Saccharopolyspora. Multiple structurally diverse spinosyn analogs are biosynthesized concurrently and can be isolated from fermentation broths of producing organisms, for example Saccharopolyspora spinosa, Saccharopolyspora pogona and Saccharopolyspora ASAGF58. Each isolated analog is given a generic name of a "spinosyn" compound, according to S. spinosa, the first described producing organism. Spinosyns share a core structure, having a polyketide-derived tetracyclic macrolide core with two saccharide moieties linked through glycosidic bonds. Many of the naturally occurring analogs exhibit potent insecticidal activities against many commercially significant pest species that cause extensive damage to crops and other plants. Some of these analogs also exhibit activity against important external parasites of livestock, companion animals and of humans. Spinosyns have a unique mechanism of action (MOA) involving disruption of nicotinic acetylcholine receptors. When compared with many other insecticides, spinosyns generally show greater selectivity toward target insects and lesser activity against many of their beneficial predators. Butenyl spinosyns are a subgroup of spinosyns, characterized by the butenyl side chain at the carbon 21 (C21) position of the macrolide core. They are produced by S. pogona (Hahn et al. (2006); EP1373290) and Saccharopolyspora ASAGF58 (Guo et al. (2020)). Several butenyl spinosyns, among them butenyl spinosyn al were shown to have comparable or even superior insecticidal activity, compared to spinosyn A, the main component of a commercial product Spinosad, produced by S. spinosa (Lewer et al. (2009)). Possibly, superior activity is caused by a more hydrophobic nature of the C21 butenyl side chain compared to C21 ethyl moiety, present in classical spinosyns, such as spinosyn A. Numerous semi-synthetic spinosyn derivatives were generated in the past, based either on the most abundant natural compounds spinosyn A and spinosyn D or on less abundant natural factors or on compounds, produced by mutants of the producing organisms, such as Saccharopolyspora spinosa (EP0837870, US10570166, W02017/040878). Butenyl spinosyns were also subjected to further chemical modification, generating numerous semi-synthetic derivatives (EP 1370566). In one study, the possibilities to derivatize the double bond of the C21 butenyl-side chain were explored (Daeuble et al. (2009)). In addition, derivatives based on the ring-expanded 14-membered lactone and C-8 hydroxyl group were produced. In contrast, many of the other sites within the spinosyn/butenyl spinosyn aglycone had been inert to chemical modification because of their saturated hydrocarbon nature. While some of the semi-synthetic derivatives were found to have interesting properties and structure-activity relationships were studied (Kirst (2010)), butenyl spinosyn or its derivatives have so far not been developed as commercial insecticidal products. In contrast, one semi-synthetic derivative, based on C21-ethyl spinosyns, named spinetoram, was developed as a commercial product (Kirst (2010)).
Spinosyns are known to be poorly soluble in water, which complicates the development of liquid formulations. Mixtures of surfactants/emulsifiers, organic solvents and adjuvants have to be added in order to assure adequate solubility of the active compounds. Therefore, novel spinosyn derivatives with improved solubility are needed to simplify formulation development and reduce the negative environmental impacts of these additives on the environment and production cost. In order to increase spinosyn solubility weakly acidic solutions are prepared or addition salts with tartrate ions are prepared (DeAmicis et al. (1997)), resulting in protonated form of the dimethylamino group on the forosamine sugar. Several quaternary ammonium salts of spinosyns have been reported, however, such modification was shown to change the biological activity of spinosyn compounds towards anti protozoan, anti-viral and anti-cancer activities (WO 2010150100, Ma et al. (2018)). Therefore, such compounds are expected to be less specific and in general less useful as insecticides for use in agriculture.
With growing concerns over the effects of pesticides on aquatic life and beneficial insects (Ramachanderan and Schaefer (2020)) such as pollinators, and inevitable occurrence of resistance among target pests, there is a need to develop and bring to market novel members of the spinosyn family, particularly of the so far neglected butenyl spinosyn class. Preferably, novel molecules should also offer advantages in terms of formulation development. Against this background, it is an object of the present invention to provide structurally novel spinosyn compounds having advantageous properties.
Summary of the invention
The present invention provides novel spinosyn compounds having advantageous properties. More specifically, the present invention provides novel spinosyn compounds showing improved solubility compared to existing spinosyn compounds such as butenyl spinosyn which represents a big advantage in preparation of formulations based on aqueous media. It is also an object of the invention to provide novel spirosyn compounds having good UV stability. In addition, some of the novel spinosyn compounds of the present invention have also shown improved insecticidal activity compared to existing spinosyn compounds such as butenyl spinosyn, Spinosad and spinetoram.
The present invention provides in a main aspect a compound of general formula (I) wherein X is NR 2 R3, NHR 2 , N + RIR 2 R3 or OR 2 and Ri, R 2 , R3, R 4 , Rs, R6, R7, Rs, R9, Rio and Rn are as defined herein; optionally in the form of a corresponding salt thereof.
The present invention further provides processes for preparation of compounds of the present invention.
The present invention further provides a composition comprising a compound of the present invention and a carrier.
The present invention further provides the use of a compound of the present invention as a pesticide. The present invention further provides a method for protecting a plant against a plant pest, comprising the step of: applying a compound of the present invention or a composition comprising the same and a carrier to a plant in need thereof.

The present invention further provides a composition comprising a compound according the present invention, optionally in the form of a corresponding salt thereof, and one or more physiologically acceptable adjuvants.
Composition of the present invention include concentrated versions, in which the present active agent is present in a concentration of from 0.001 to 98.0 percent, with the remaining content being physiologically acceptable carriers. Such compositions, especially those with less than 50 percent of the present compound, can sometimes be used directly, but these compositions can also be diluted with other physiologically acceptable carriers to form more dilute treating formulations. These latter compositions can include the active agent in lesser concentrations of from 0.001 to 0.1 percent. Compositions are prepared according to the procedures and formulas which are conventional in the agricultural or pest control art. The compositions may be concentrated and dispersed in water or may be used in the form of a dust, bait or granular formulation. The dispersions are typically aqueous suspensions or emulsions prepared from concentrated formulations of the compounds. The water- soluble or water-suspension or emulsifiable formulations are either solids, wettable powders, or liquids, known as emulsifiable concentrates or aqueous suspensions. Wettable powders may be agglomerated or compacted to form water dispersible granules. These granules comprise mixtures of compound, inert carriers and surfactants. The concentration of the compound is typically between about 0 .1% to about 90% by weight. The inert carrier is typically attapulgite clays, montmorillonite clays and the diatomaceous earths or purified silicates. Surfactants comprise typically about 0.5% to about 10% of the wettable powder. Surfactants include sulfonated lignins, condensed napthalene- sulfonates, the napthalenesulfonates, alkyl-benenesulfonates, alkysulfonates or nonionic surfactants such as ethylene oxide adducts of alkylphenols or mixtures thereof. Emulsifiable concentrates of the derivatives of the invention typically range from about 50 to about 500 grams of spinosyn derivative per liter of liquid, equivalent to about 10% to about 50%, dissolved in an inert carrier which is a mixture of a water immiscible solvent and emulsifiers. Organic solvents include organics such as xylenes, and petroleum fractions such as high-boiling naphthlenic and olefinic portions of petroleum which include heavy and aromatic naphtha. Other organics may also be used such as terpenic solvents -rosin derivatives, aliphatic ketones such as cyclohexanone and complex alcohols. Emulsifiers for emulsifiable concentrates are typically mixed ionic and/or nonionic surfactants such as those mentioned herein or their equivalents. Aqueous suspensions may be prepared containing water- insoluble spinosyn derivatives, where the compounds are dispersed in an aqueous vehicle at a concentration typically in the range of between about 5% to about 50% by weight. The suspensions are prepared by finely grinding the compound and vigorously mixing it into a vehicle of water, surfactants, and dispersants. Inert ingredients such as inorganic salts and synthetic or natural gums may also be employed to increase the density and/or viscosity of the aqueous vehicle as is desired. Precipitated flowables may be prepared by dissolving at least one spinosyn derivative of the invention in a water-miscible solvent and surfactants or surface active polymers. When these formulations are mixed with water, the active spinosyn derivative precipitates with the surfactant controlling the size of the resulting micro-crystalline precipitate. The size of the crystal can be controlled through the selection of specific polymer and surfactant mixtures. The spinosyn derivatives may also be applied as a granular composition that is applied to the soil. The granular composition typically contains from about 0.5% to about 10% by weight of the derivative. The spinosyn derivative is dispersed in an inert carrier which is typically clay or an equivalent substance. Generally, granular compositions are prepared by dissolving the compounds of the invention in a suitable solvent and applying it to a granular carrier which has been pre-formed to the desirable particle size. The particle size is typically between about 0.5 mm to 3 mm. The granular compositions may also be prepared by forming a dough or paste of the carrier and compound, drying the combined mixture, and crushing the dough or paste to the desired particle size.
The spinosyn compounds may also be combined with an appropriate organic solvent. The organic solvent is typically a bland petroleum oil that is widely used in the agricultural industry. These combinations are typically used as a spray. More typically, the spinosyn compounds are applied as a dispersion in a liquid carrier, where the liquid carrier is water. The compounds may also be applied in the form of an aerosol composition. The compound is dissolved in an inert carrier, which is a pressure generating propellant mixture. The aerosol composition is packaged in a container, where the mixture is dispersed through an atomizing valve. Propellant mixtures contain either low-boiling halocarbons, which may be mixed with organic solvents or aqueous suspensions pressurized with inert gases or gaseous hydrocarbons. The compounds may be applied to any locus inhabited by an insect or mite. Such locus typically is cotton, soybean and vegetable crops, fruit and nut trees, grape vines, houses and ornamental plants. The amount of the spinosyn compound applied to the loci of insects and mites can be determined by those skilled in the art. Generally, the concentrations of from about 10 ppm to about 5,000 ppm provide the desired control. For crops such as soybeans and cotton, the rate of application is about 0.01 to about 1 kg/ha, where the spinosyn derivative is applied in a 5 to 50 gal/A spray formulation.
The composition can be formulated in a liquid concentrate, ready-to-use (RTU) liquid spray, dust, or solid form. The formulation chosen will depend on the use of the product. The following general treatment methods are preferably suitable for carrying out the seed treatment, or plant propagation material treatment, according to the invention: dry treatments (preferably with addition of adhesion promoters such as, for example, liquid paraffin or talc), and, if appropriate, colorants, slurry treatments (preferably with addition of wetters, dispersants, emulsifiers, adhesives, inert fillers and colorants), aqueous liquid treatments (preferably with addition of emulsifiers, dispersants, thickeners, antifreeze agents, polymers, adhesives and colorants), solvent-based liquid treatments (with addition of solvents and colorants), emulsion treatments (with addition of emulsifiers, solvents and colorants).

Example 10: Evaluation of kinetic solubility of spinosyn compounds
Solubility of the compounds of the invention was assessed using kinetic solubility assay and compared to solubility of butenyl spinosyn. Stock solutions of spinosyn compounds were prepared in DMSO at 10 mM concentration). 10 uL of the stock solutions were added into 490 of in K.S. 5.4 buffer of pH 5.4 (80mM phosphoric acid, acetic acid, boric acid buffer, adjusted the pH to pH 5.4 with 1 N HCI and IN NaOH) or K.S. 7.4 buffer with pH of 7.4 (80mM phosphoric acid, acetic acid, boric acid buffer, adjusted the pH to pH 7.4 with 1 N HCI and IN NaOH). The solutions were incubated with shaking at room temperature (25 ±2 °C) for 24 hours. 200 uL of each solution were then transferred into a new Multiscreen filter plate (Membrane of polycarbonate) and filtered by millipore vacuum manifold, and the filtrate was collected. The concentrations of tested compounds in the filtered samples were analyzed by HPLC analysis calibrated by a standard curve generated by injection of 3 standard solutions of the relevant compound with concentrations of 1, 20, 200 pM. The results of the testing are presented in Table 1. The conditions of HPLC analysis are presented in Table 2.

These results show that the compounds of the invention are significantly more soluble in the neutral pH values (7.4) compared to butenyl spinosyn, which represents a big advantage in preparation of formulations based on aqueous media.
Example 11: Evaluation of biological activity of spinosyn compounds
Insecticide activities of the compounds of this invention were assessed in comparison with commercially available samples of spinosad (LGC (Dr. Ehrenstorfer); Product code: DRE-C16972830) and spinetoram (LGC (Dr. Ehrenstorfer); Product code: DRE-C16972770) Solutions of spinosyn compounds were prepared by adding 0.05% Tween 80, lowering pH to 5.95 and sonicating. Two concentrations of each compound were used, 0.1 pg/mL and 0.3 pg/mL, with each condition tested in four parallels.
Freshly collected corn leaves were dipped into the prepared solutions. After dipping leaves were left to dry at room temperature for 1 hour. Each dry leaf was then infested with 4 larvae (development stage LI), and the experimental device was incubated at 21 °C - 23°C for 24 h in order to optimize insect development. At two timings post infestation (3 days and 6 days), the insecticide efficacy is evaluated from the number of living larvae using the Henderson-Tilton method. Untreated control was integrated for normalization and validation of larvae health. Table 3: Comparison of efficacy of tested spinosyn compounds

These results show that the compound HI shows extremely potent insecticidal activity on Ostrinia nubilialis larvae. The activity is comparable or superior to Spinosad and spinetoram.
Example 12: UV-stability of spinosyn compounds
Synthesized spinosyn compounds were used to prepare 5 mM solutions in acetonitrile. The solution was divided in 2 aliquots and one aliquot was exposed to UV light at 254 nm and the other aliquot was incubated in the same conditions without UV light exposure. Quantities of remaining starting compounds were determined by HPLC after Oh, lh, 5h and 10 h. The results are presented in Table 4. Table 4. shares of remaining compounds after exposure to UV light.
Example 13: Evaluation of biological activity of additional spinosyn compounds Insecticide activities of the compounds of this invention were assessed in comparison with commercially available samples of spinosad (LGC (Dr. Ehrenstorfer); Product code: DRE-C16972830) and spinetoram (LGC (Dr. Ehrenstorfer); Product code: DRE-C16972770) Solutions of spinosyn compounds were prepared by adding 0.05% Tween 80, lowering pH to 5.95 and sonicating.

These results show that the compound Hla shows lower insecticidal activity on Ostrinia nubilialis larvae than its natural precursor spinosad. It is surprising that an equivalent chemical modification, addition of a methoxy group at position 7, reduces the activity of spinosyn A while, in contrast it increases the activity when added to the butenyl spinosyn scaffold - see Example 11.
Example 14: Toxicity of compounds on honey bees
Toxicity of the compounds of this invention towards honey bees ( Apis melifera carnica, Pollman 1879) was assessed in comparison with commercially available samples of spinosad (LGC (Dr. Ehrenstorfer); Product code: DRE-C16972830) and the naturally produced compound butenyl spinosyn alpha 1. Solutions of spinosyn compounds were prepared in 100 mM ammonium acetate, pH = 5, and later diluted in 50 % (500 g/L) sucrose solution in water to final concentrations. Two final concentrations were used for each compound, 7.76 pmol/L and 15.53 pmol/L.
Single dose acute oral toxicity tests were conducted on adult worker bees according to previously described standard methods (Medrzycki at el., (2013)). Each compound and condition were tested in two parallels. Briefly, each parallel experiment consisted of 5 cages with 20 honey bees per cage. Each cage was supplied with 200 pL of spinosyn compound-containing solution, prepared as described above, resulting in the oral dose of the active spinosyn compound 0.078 nmol or 0.155 nmol per honey bee, which corresponds to previously established 100% LD 5 o (0.057 pg/bee) and 200% LD 5 o (0.114 pg/bee) for Spinosad. After uptake of the solutions honey bees were supplied with standard 50 % sucrose solution and observed at 24h and 48h and the number of dead and live bees was estimated. Ammonium acetate solution with pH 5 was used as the negative control. Results are presented in Table 6. Table 6. Percentage of surviving honey bees at different time points after application of a single dose of butenyl spinosyn and its derivatives/prodrugs J1A-H1 and J7-H1.
Conclusion: Naturally occurring butenyl spinosyn showed higher toxicity to honey bees in acute oral toxicity test compared to the derivatives provided by this invention.
