Abstract
Description
[0001] This application is a divisional application of Chinese invention patent application (application date: October 15, 2021; application number: 202180083881.6 (international application number: PCT / US2021 / 055173); invention title: MALT1 regulator and its use).
[0002] Cross-reference to related applications
[0003] This application claims priority and benefit to U.S. Provisional Patent Application No. 63 / 092,768, filed October 16, 2020, the entire contents of which are incorporated herein by reference. Background of the Invention
[0005] Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is an intracellular signaling protein known from both innate immune cells (such as natural killer (NK) cells, dendritic cells (DCs), and mast cells) and adaptive immune cells (such as T cells and B cells). MALT1 plays a crucial role in influencing immune responses. For example, in T cell receptor signaling, MALT1 mediates nuclear factor kappa B (NFKB) signaling, leading to T cell activation and proliferation. Therefore, MALT1 is significant for understanding the mechanisms of autoimmunity and inflammatory pathology. Furthermore, constitutive (dysregulated) MALT1 activity is associated with cancers such as MALT lymphoma and activated B-cell-like diffuse large B-cell lymphoma (ABC-DLBCL). Modulators of MALT1 activity could be used as potential therapeutic agents. Invention Overview

[0038] definition
[0039] Chemical definition
[0040] The definitions of specific functional groups and chemical terms are described in more detail below. Chemical elements are identified according to the periodic table, CAS version, Handbook of Chemistry and Physics, 75th edition (internal page), and specific functional groups are generally defined as described herein. Furthermore, see Thomas Sorrell, Organic Chemistry, University Science Books, Sausalito, 1999; Smith and March, March's Advanced Organic Chemistry, 5 th Edition, John Wiley & Sons, Inc., New York, 2001; Larock, Comprehensive Organic Transformations, VCH Publishers, Inc., New York, 1989; and Carruthers, Some Modern Methods of Organic Synthesis, 3 rd The book describes the general principles of organic chemistry, as well as specific functional groups and reactivity, in Edition 1987, Cambridge University Press, Cambridge.
[0041] The compounds described herein may contain one or more asymmetric centers and therefore may exist in various isomeric forms, such as enantiomers and / or diastereomers. For example, the compounds described herein may be in the form of individual enantiomers, diastereomers, or geometric isomers, or may be in the form of mixtures of stereoisomers, including racemic mixtures and mixtures rich in one or more stereoisomers. Isomers may be isolated from the mixture by methods known to those skilled in the art, including chiral high-performance liquid chromatography (HPLC) and the formation and crystallization of chiral salts; or preferred isomers may be prepared by asymmetric synthesis. See, for example, Jacques et al., Enantiomers, Racemates and Resolutions (Wiley Interscience, New York, 1981); Wilen et al., Tetrahedron 33:2725 (1977); Eliel, Stereochemistry of Carbon Compounds (McGraw–Hill, NY, 1962); and Wilen, Tables of Resolving Agents and Optical Resolutions, page 268 (EL Eliel, ed., Univ. of Notre Dame Press, Notre Dame, IN 1972). This invention further covers the compounds described herein in their single isomer form, substantially free of other isomers, and alternatively in mixtures of different isomers.
[0042] As used herein, a pure enantiomer is substantially free of other enantiomers or stereoisomers of the compound (i.e., exhibiting an enantiomeric excess). In other words, the “S” form of the compound is substantially free of the “R” form of the compound, and therefore exhibits an enantiomeric excess of the “R” form. The terms “enantiomerically pure” or “pure enantiomer” mean that the compound contains more than 75 wt%, more than 80 wt%, more than 85 wt%, more than 90 wt%, more than 91 wt%, more than 92 wt%, more than 93 wt%, more than 94 wt%, more than 95 wt%, more than 96 wt%, more than 97 wt%, more than 98 wt%, more than 98.5 wt%, more than 99 wt%, more than 99.2 wt%, more than 99.5 wt%, more than 99.6 wt%, more than 99.7 wt%, more than 99.8 wt%, or more than 99.9 wt% of enantiomers. In some implementations, the weight is based on the total weight of all enantiomers or stereoisomers of the compound.
[0043] In the compositions provided herein, the enantiomerically pure compound may be present with other active or inactive ingredients. For example, a pharmaceutical composition comprising an enantiomerically pure R-compound may comprise, for example, about 90% excipients and about 10% enantiomerically pure R-compound. In some embodiments, the enantiomerically pure R-compound in such compositions may, for example, comprise at least about 95% by weight of the R-compound and at most about 5% by weight of the S-compound, based on the total weight of the compounds. For example, a pharmaceutical composition comprising an enantiomerically pure S-compound may comprise, for example, about 90% excipients and about 10% enantiomerically pure S-compound. In some embodiments, the enantiomerically pure S-compound in such compositions may, for example, comprise at least about 95% by weight of the S-compound and at most about 5% by weight of the R-compound, based on the total weight of the compounds. In some embodiments, the active ingredient may be formulated with or without a small amount of excipients or a carrier.

[0232] Pharmaceutical Compositions and Routes of Administration
[0233] The compounds provided according to the present invention are typically administered in the form of pharmaceutical compositions. Therefore, the present invention provides pharmaceutical compositions comprising one or more of the said compounds as active ingredients, or pharmaceutically acceptable salts or esters thereof, and one or more pharmaceutically acceptable excipients, carriers including inert solid diluents and fillers, diluents including sterile aqueous solutions and various organic solvents, permeation enhancers, solubilizers, and adjuvants. The pharmaceutical compositions may be administered alone or in combination with other therapeutic agents. Such compositions are prepared in a manner well known in the pharmaceutical industry (see, for example, Remington's Pharmaceutical Sciences, Mace Publishing Co., Philadelphia, Pa. 17th Ed. (1985); and Modern Pharmaceutics, Marcel Dekker, Inc. 3rd Ed. (GS Banker & CT Rhodes, Eds.)).
[0234] The pharmaceutical composition may be administered in single or multiple doses via any of the accepted routes of administration of the pharmaceutical agent having similar efficacy, such as those described by reference in those patents and patent applications, including rectal, sublingual, nasal and transdermal routes, intra-arterial injection, intravenous administration, intraperitoneal administration, parenteral administration, intramuscular administration, subcutaneous administration, oral administration, local administration, as an inhaler, or via an impregnation or coating device, such as a stent, like a cylindrical polymer inserted into an artery.
[0235] One mode of administration is parenteral administration, particularly by injection. The novel compositions of the present invention can be incorporated into forms for injection administration including aqueous or oily suspensions or emulsions containing sesame oil, corn oil, cottonseed oil, or peanut oil, as well as elixirs, mannitol, dextrose, or sterile aqueous solutions and similar vehicle media. Saline solutions are also commonly used for injection, but are less preferred in the context of the present invention. Ethanol, glycerol, propylene glycol, liquid polyethylene glycol, etc. (and suitable mixtures thereof), cyclodextrin derivatives, and vegetable oils may also be used. Suitable flowability can be maintained, for example, by using a coating such as lecithin, in the case of dispersions by maintaining the desired particle size, and by using surfactants. Microbial action can be prevented by various antibacterial and antifungal agents, such as parabens, chlorobutanol, phenol, sorbic acid, thimerosal, etc.
[0236] Sterile injectable solutions are prepared by incorporating the required amount of the compound according to the invention, along with various other components listed above, into a suitable solvent, followed by filtration sterilization if necessary. Typically, dispersions are prepared by incorporating various sterilized active ingredients into a sterile carrier containing a basic dispersion medium and the other desired components listed above. In the case of sterile powders used to prepare sterile injectable solutions, preferred methods of preparation include vacuum drying and freeze-drying techniques, which produce powders of the active ingredient plus any additional desired components derived from their previously sterile filtered solutions.
[0237] Oral administration is another route of administration for the compounds of the present invention. Administration may be via capsules or enteric-coated tablets, etc. In the preparation of pharmaceutical compositions comprising at least one of the compounds described herein, the active ingredient is typically diluted with an excipient and / or encapsulated within a carrier to present in the form of capsules, sachet, paper, or other containers. When the excipient is used as a diluent, it can be a solid, semi-solid, or liquid material (as above), which acts as a medium, carrier, or medium for the active ingredient. Thus, the composition can be in the form of tablets, pills, powders, lozenges, sachets, elixirs, suspensions, emulsions, solutions, syrups, aerosols (as a solid or in a liquid medium), ointments containing, for example, up to 10% by weight of the active compound, soft and hard gelatin capsules, sterile injections, and sterile packaged powders.
[0238] Some examples of suitable excipients include lactose, glucose, sucrose, sorbitol, mannitol, starch, gum arabic, calcium phosphate, alginate, tragacanth gum, gelatin, calcium silicate, microcrystalline cellulose, polyvinylpyrrolidone, cellulose, sterile water, syrup, and methylcellulose. Formulations may also include: lubricants such as talc, magnesium stearate, and mineral oil; wetting agents; emulsifiers and suspending agents; preservatives such as methyl benzoate and hydroxypropyl benzoate; sweeteners; and flavoring agents.
[0239] The compositions of the present invention can be formulated using methods known in the art to provide rapid, sustained, or delayed release of the active ingredient after administration to a patient. Controlled-release drug delivery systems for oral administration include osmotic pump systems and dissolution systems containing polymer-coated reservoirs or drug-polymer matrix formulations. Examples of controlled-release systems are given in U.S. Patent Nos. 3,845,770; 4,326,525; 4,902,514; and 5,616,345. Another formulation used in the methods of the present invention employs a transdermal drug delivery device (“patch”). Such transdermal patches can be used to provide continuous or discontinuous infusions of the compounds of the present invention in controlled amounts. The construction and use of transdermal patches for drug delivery are well known in the art. See, for example, U.S. Patent Nos. 5,023,252, 4,992,445, and 5,001,139. Such patches can be constructed for continuous, pulsed, or on-demand drug delivery.
[0240] The composition is preferably formulated as a unit dosage form. The term "unit dosage form" refers to a physically separated unit suitable as a single dose for human subjects and other mammals, each unit containing a predetermined amount of active substance calculated to produce the desired therapeutic effect, and suitable pharmaceutical excipients (e.g., tablets, capsules, and ampoules). These compounds are typically administered in an effective amount. Preferably, for oral administration, each dose unit contains 1 mg to 2 g of the compound described herein, and for parenteral administration, preferably 0.1 to 700 mg of the compound described herein. However, it should be understood that the actual amount of compound administered is usually determined by the physician based on relevant circumstances, including the condition to be treated, the chosen route of administration, the compound actually administered and its relative activity, the individual patient's age, weight and response, the severity of the patient's symptoms, etc.
[0241] To prepare solid compositions, such as tablets, the main active ingredient is mixed with a pharmaceutical excipient to form a solid preformed composition containing a homogeneous mixture of the compounds of the present invention. When these preformed compositions are referred to as homogeneous, it means that the active ingredient is uniformly dispersed throughout the composition so that the composition can be easily subdivided into equivalent unit dosage forms, such as tablets, pills, and capsules.
[0242] The tablets or pills of the present invention can be coated or otherwise compounded to provide a dosage form with the advantage of prolonged action, or to protect them from the acidic conditions of the stomach. For example, the tablets or pills may comprise an inner dose component and an outer dose component, the latter covering the former in an encapsulated form. These two components may be separated by an enteric coating, which prevents the components from disintegrating in the stomach and allows the inner component to be delivered intact into the duodenum or to delay release. A wide variety of materials can be used for such an enteric coating or coating, including many polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol, and cellulose acetate.
[0243] Compositions for inhalation or inhalation include solutions and suspensions in pharmaceutically acceptable water or organic solvents, or mixtures thereof, as well as powders. Liquid or solid compositions may contain suitable pharmaceutically acceptable excipients, as described above. Preferably, the composition can be administered via oral or nasal inhalation to produce a local or systemic effect. Compositions in preferred pharmaceutically acceptable solvents can be nebulized using an inert gas. The nebulized solution can be inhaled directly from a nebulizing device, or the nebulizing device can be connected to a face mask inhaler or an intermittent positive pressure ventilator. Solution, suspension, or powder compositions can be administered from a device that delivers the formulation in a suitable manner, preferably orally or intranasally.
[0244] In some embodiments, a pharmaceutical composition comprising the disclosed compound or a pharmaceutically acceptable salt thereof and a pharmaceutically acceptable carrier is included.

[0872] Example 2. MALT1 Biochemical Assay
[0873] Inhibitory efficacy was assessed by measuring the enzymatic activity of full-length MALT1 (SEQ ID NO: 1) at different concentrations of the compound. The enzymatic assay consisted of a single substrate reaction that monitored the release of a fluorescent dye during peptide substrate cleavage. The peptide substrate had the following sequence: Ac-Leu-Arg-Ser-Arg-Rh110-dPro (custom-synthesized by WuXi AppTec, Shanghai, China). The assay buffer consisted of 50 mM Hepes, pH 7.5, 0.8 M sodium citrate, 1 mM DTT, 0.004% Tween-20, and 0.005% bovine serum albumin (BSA). Steady-state kinetic analysis of peptide substrate binding resulted in the Michaelis-Menten constant (K0). M The concentration was 150 µM. The assay was performed in 384-well F-bottom polypropylene black microplates (Greiner Bio_One, catalog number 781209) with 15 nM enzyme and 30 µM peptide substrate. After 60 minutes, the reaction was quenched by adding 10 mM iodoacetate. Total fluorescence was measured using an Envision (PerkinElmer) at 485 nm excitation and 520 nm emission.
[0874] To determine potency, 1 µL of serially diluted compound (in 100% DMSO) was pre-incubated with 40 µL of enzyme for 30 min. The reaction was initiated with 10 µL of peptide substrate. Relative fluorescence units were converted to percentage of inhibition using 0% and 100% inhibition controls as references. The 100% inhibition control was prepared by 1 µM final concentration of (S)-1-(5-chloro-6-(2H-1,2,3-triazol-2-yl)pyridin-3-yl)-3-(2-chloro-7-(1-methoxyethyl)pyrazolo[1,5-a]pyrimidin-6-yl)urea (IC50). 50 = 15nM) was used, while the 0% inhibitory control consisted of 2% DMSO. IC 50 The values are calculated by fitting the concentration-response curve to a four-parameter logic equation in GraphPadPrism.
