TROPOMYOSIN-RELATED KINASE (TRK) INHIBITORS

Tropomyosin-related kinase inhibitors (Trk inhibitors) are small molecule compounds useful in the treatment of disease. Trk inhibitors can be used as pharmaceutical agents and in pharmaceutical compositions. Trk inhibitors are useful in the treatment of inflammatory diseases, autoimmune disease, defects of bone metabolism and/or cancer, and are particularly useful in the treatment of osteoarthritis (OA), pain, and pain associated with OA. Trk inhibitors are also useful for inhibiting tropomyosin-related kinase A (TrkA), tropomyosin-related kinase B (TrkB), tropomyosin-related kinase C (TrkC), and/or c-FMS (the cellular receptor for colony stimulating factor-1 (CSF-1)).

Because enzymes can increase reaction rates by enormous factors and tend to be very specific, 73874-95-0, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 73874-95-0

Condensation of 2-((Alkylthio)(aryl)methylene)malononitrile with 1,2-Aminothiol as a Novel Bioorthogonal Reaction for Site-Specific Protein Modification and Peptide Cyclization

Site-specific modification of peptides and proteins has wide applications in probing and perturbing biological systems. Herein we report that 1,2-aminothiol can react rapidly, specifically and efficiently with 2-((alkylthio)(aryl)methylene)malononitrile (TAMM) under biocompatible conditions. This reaction undergoes a unique mechanism involving thiol-vinyl sulfide exchange, cyclization, and elimination of dicyanomethanide to form 2-aryl-4,5-dihydrothiazole (ADT) as a stable product. An 1,2-aminothiol functionality can be introduced into a peptide or a protein as an N-terminal cysteine or an unnatural amino acid. The bioorthogonality of this reaction was demonstrated by site-specific labeling of not only synthetic peptides and a purified recombinant protein but also proteins on mammalian cells and phages. Unlike other reagents in bioorthogonal reactions, the chemical and physical properties of TAMM can be easily tuned. TAMM can also be applied to generate phage-based ADT-cyclic peptide libraries without reducing phage infectivity. Using this approach, we identified ADT-cyclic peptides with high affinity to different protein targets, providing valuable tools for biological studies and potential therapeutics. Furthermore, the mild reaction conditions of TAMM condensation warrant its use with other bioorthogonal reactions to simultaneously achieve multiple site-specific modifications.

Arylsulfonamide derivatives of (aryloxy)ethylpiperidines as selective 5-HT7 receptor antagonists and their psychotropic properties

A series of alkyl/arylsulfonamide derivatives of (aryloxy)ethylpiperidines as highly potent 5-HT7 receptor antagonists has been developed through structure-based design on the previously identified compound PZ-766. This resulted in highly potent antagonist 10 (3-fluoro-N-(1-{2-[(propan-2-yl)phenoxy]ethyl}piperidin-4-yl)-benzenesulfonamide) which was more active in vivo than PZ-766 and SB-269970 in forced swim test in mice (MED = 2.5 mg kg-1), and displayed comparable effects to SB-269970 in four-plate test in mice (MED = 1.25 mg kg-1) and novel object recognition test in rats (MED = 1 mg kg-1). The results highlight the antidepressant, anxiolytic and pro-cognitive potential of the arylsulfonamide derivatives of (aryloxy)ethylpiperidines with 5-HT7 receptor antagonist properties and warrant further studies to explore their therapeutic potential for the treatment of CNS disorders.

General procedure: To a stirred solution of 2 (0.20 g, 1.00 mmol) in anhydrous DCM(5 mL) was added Et3N (0.42 mL, 3.00 mmol) at room temperature.Then 3a-i (3.96 mmol) was added in small portions at room temperature.The reaction was stirred for 4 h at this temperature and then quenched the reaction with saturated aqueous solution ofNaHCO3. The aqueous layer was extracted with ethyl acetate(3 10 mL). The combined organic layers were dried over anhydrousNa2SO4, filtered, and concentrated. Silica gel flash columnchromatography (EtOAc/hexanes = 1:2) of the residue gave 4a-ias the product. Dissolved 4a-i (0.34 g, 0.97 mmol) in 25 mL TFAat room temperature, the reaction was stirred at room temperature for 10 h. Distilled the TFA under vacuum and then diluted with saturated aqueous solution of NaHCO3. The aqueous layer wasextracted with ethyl acetate (3 10 mL). The combined organiclayers were dried over anhydrous Na2SO4, filtered, and concentrated.Silica gel flash column chromatography (EtOAc/hexanes =1:1) of the residue gave 5a-i as the product.
