Description:
MCL-1 INHIBITORS AND METHODS OF USE THEREOF

Background

Myeloid Cell Leukemia 1 (Mcl-1 ) is an important anti-apoptotic member of the BCL-2 family of proteins and a master regulator of cell survival. Amplification of the MCL1 gene and/or overexpression of the Mcl-1 protein has been observed in multiple cancer types and is commonly implicated in tumor development. In fact, MCL1 is one of the most frequently amplified genes in human cancer. In many malignancies, Mcl-1 is a critical survival factor and it has been shown to mediate drug resistance to a variety of anti-cancer agents.

Mcl-1 promotes cell survival by binding to pro-apoptotic proteins like Bim, Noxa, Bak, and Bax and neutralizing their death-inducing activities. Inhibition of Mcl-1 thereby releases these pro-apoptotic proteins, often leading to the induction of apoptosis in tumor cells dependent on Mcl-1 for survival. Therapeutically targeting Mcl-1 alone or in combination with other therapies, therefore, is a promising strategy to treat a multitude of malignancies and to overcome drug resistance in many human cancers.

The language "pharmaceutically acceptable salt" includes acid addition or base salts that retain the biological effectiveness and properties of any of the compounds disclosed herein which typically are not biologically or otherwise undesirable. In many cases, the compounds disclosed herein are capable of forming acid and/or base salts by virtue of the presence of basic and/or carboxyl groups or groups similar thereto. In one embodiment, the pharmaceutically acceptable salt includes quaternary ammonium salts.

Pharmaceutically acceptable acid addition salts can be formed with inorganic acids and organic acids, e.g., acetate, aspartate, benzoate, besylate, bromide/hydrobromide,

bicarbonate/carbonate, bisulfate/sulfate, camphorsulfonate, chloride/hydrochloride,

chlortheophyllonate, citrate, ethanedisulfonate, fumarate, gluceptate, gluconate, glucuronate, hippurate, hydroiodide/iodide, isethionate, lactate, lactobionate, laurylsulfate, malate, maleate, malonate, mandelate, mesylate, methylsulfate, naphthoate, napsylate, nicotinate, nitrate, octadecanoate, oleate, oxalate, palmitate, palmoate, phosphate/hydrogen

phosphate/dihydrogen phosphate, polygalacturonate, propionate, stearate, succinate, subsalicylate, sulfate/hydrogensulfate, tartrate, tosylate and trifluoroacetate salts. Inorganic acids from which salts can be derived include, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like. Organic acids from which salts can be derived include, for example, acetic acid, propionic acid, glycolic acid, oxalic acid, maleic acid, malonic acid, succinic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, toluenesulfonic acid, trifluoroacetic acid,

sulfosalicylic acid, and the like.

Pharmaceutically acceptable base addition salts can be formed with inorganic and organic bases. Inorganic bases from which salts can be derived include, for example, ammonia and salts of ammonium and metals from columns I to XII of the periodic table. In certain embodiments, the salts are derived from sodium, potassium, ammonium, calcium, magnesium, iron, silver, zinc, and copper; particularly suitable salts include ammonium, potassium, sodium, calcium and magnesium salts. Organic bases from which salts can be derived include, for example, primary, secondary, and tertiary amines, substituted amines including naturally occurring substituted amines, cyclic amines, basic ion exchange resins, and the like. Certain organic amines include isopropylamine, benzathine, cholinate, diethanolamine, diethylamine, lysine, meglumine, piperazine and tromethamine.

The pharmaceutically acceptable salts of the compounds disclosed herein can be synthesized from a basic or acidic moiety, by conventional chemical methods. Generally, such salts can be prepared by reacting free acid forms of these compounds with a stoichiometric amount of the appropriate base (such as Na + , Ca 2+ , Mg 2+ , or K + hydroxide, carbonate, bicarbonate or the like), or by reacting free base forms of these compounds with a

stoichiometric amount of the appropriate acid. Such reactions are typically carried out in water or in an organic solvent, or in a mixture of the two. Generally, use of non-aqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile is desirable, where practicable. Lists of additional suitable salts can be found, e.g., in "Remington's Pharmaceutical Sciences," 20th ed., Mack Publishing Company, Easton, Pa., (1985); Berge et al., "J. Pharm. Sci., 1977, 66, 1 -19 and in "Handbook of Pharmaceutical Salts: Properties, Selection, and Use" by Stahl and Wermuth (Wiley-VCH, Weinheim, Germany, 2002).

Any formula given herein is also intended to represent unlabeled forms as well as isotopically labeled forms for the compounds disclosed herein. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom of the same element but with differing mass number. Examples of isotopes that can be incorporated into any of the comounds disclosed herein and their salts include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as 2 H, 3 H, 11 C, 13 C, 14 C, 15 N, 35 S and 125 l. The compounds disclosed herein may include various isotopically labeled compounds into which radioactive isotopes, such as, 3 H, 11 C, 14 C, 35 S and 36 CI are present. Isotopically labeled compounds disclosed herein can generally be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the accompanying Examples using appropriate isotopically labeled reagents in place of the non-labeled reagents previously employed.

The compounds disclosed herein may have different isomeric forms. The language "optical isomer" or "stereoisomer" refers to any of the various stereoisomeric configurations which may exist for any of the compounds disclosed herein. In particular, the compounds disclosed herein possess axial chirality, by virtue of restricted rotation around a biaryl bond and as such may exist as mixtures of enantiomers/atropisomers with enantiomeric excess between about 0% and >98% e.e. When a compound is a pure enantiomer, the stereochemistry at each chiral center may be specified by either R a or S a . Such designations may also be used for mixtures that are enriched in one enantiomer. Further description of atropisomerism and axial chirality and rules for assignment of configuration can be found in Eliel, E.L. & Wilen, S. H. 'Stereochemistry of Organic Compounds' John Wiley and Sons, Inc. 1994. Resolved

compounds whose absolute configuration is unknown can be designated (+) or (-) depending on the direction (dextro- or levorotatory) which they rotate plane polarized light at the wavelength of the sodium D line. The present disclosure is meant to include all such possible isomers, including racemic mixtures, optically pure forms and intermediate mixtures. Optically active {Ra)- and (S a )-isomers may be prepared using chiral synthons, chiral reagents or chiral catalysts, or resolved using conventional techniques well known in the art, such as chiral HPLC.

Also disclosed herein the Intermediates 1 -149 in the Examples, and salts thereof.

Biochemical binding TR-FRET assay for measuring protein complex disruption

TR-FRET assay was used to assess the ability of compounds to disrupt the interaction between recombinant human Mcl-1 with a labeled BIM peptide probe. The assay was constructed such that GST tagged Mcl-1 protein, was incubated with a Europium-labeled anti- GST antibody and a HyLite Fluor 647-labeled peptide corresponding to the BH3 domain of BIM. Compound IC 5 o values were assessed following a 10-point, half-log dilution schema starting at 100 uM or 10 μΜ compound concentration. Specifically, human Mcl-1 enzyme from Mcl-1 (E171 -G327) was cloned into an overexpression vector, expressed as an /V-terminal GST- tagged fusion protein in E coli. and subsequently purified via Glutathione Sepharose-affinity and size-exclusion chromatography. The assay was performed in 384-Well LV plates (Greiner cat #784075) and run in the presence and absence of the compound of interest. Each well of 12 μΙ_ assay mixture contained 10 mM Tris (pH 7.4), 1 .0 mM DTT, 0.005% Tween-20, 150 mM NaCI, 10% DMSO, and 1 .5 nM GST_Mcl-1 , 0.5 nM LanthaScreen Eu tagged GST antibody (Invitrogen Catalog # PV5594), 4.0 nM HyLite Fluor 647-labeled BIM peptide [C(Hilyte647 C2 Maleimide)- WIAQELRRIGDEFN] (SEQ ID NO:1 ). Reactions were incubated at 24 °C for 90 min before reading on a Tecan M1000 spectrfluorometer with excitation at 340 nm and emission at 612nm & 665 nm. Subsequently, ratio of fluorescent emission intensity at 665 nm to 612 nm was calculated for each reaction, and the dose-response of the ratio to testing compound

concentration was fitted to a select fit model that will provide the best fit quality using automatic parameter to derive IC 5 o values for each testing compound.

Caspase Activity assay

This is a cell assay to measure the induction of apoptosis in MOLP-8 (multiple myeloma), MV4;1 1 (acute myeloid leukemia), and NCI-H23 (non-small cell lung cancer) cells after 6 h treatment with Mcl-1 inhibitors. On the first day, 3000 (MOLP-8, MV4;1 1 ) or 1250 (NCI- H23) cells/well were seeded with 50 μΐ of growth media (IMDM + 10% FBS+2 mM L-Glu for MV4;1 1 and RPMI-1640 + 10% FBS+2 mM L-Glu for all others) in 384-well white microplates, and incubated overnight (37 °C, 5% C0 2 , 80% RH). On the second day, the cells were treated with Mcl-1 inhibitors using an ECHO acoustic liquid handler (10 point half-log serial dilution, 31 .5 μΜ top concentration, 0.3% final DMSO concentration). After 6 h incubation (37 °C, 5% C0 2 , 80% RH), 25 μΐ of Caspase-Glo 3/7 reagent (Promega) was added into each well, and plates were incubated at room temperature for 30 min protected from light. Luminescence was recorded using an Infinite M200 microplate reader (Tecan) with a 100 ms integration time. EC 5 o values were calculated using GeneData analysis software.
