cKIT kinase inhibitors, e.g., imatinib, could induce drug-acquired mutations such as cKIT T670I that rendered drug resistance after chronic treatment. Through a type II kinase inhibitor design approach we discovered a highly potent type II cKIT kinase inhibitor compound 35 (CHMFL-KIT-8140), which potently inhibited both cKIT wt (IC50 = 33 nM) and cKIT gatekeeper T670I mutant (IC50 = 99 nM). Compound 35 displayed strong antiproliferative effect against GISTs cancer cell lines GIST-T1 (cKIT wt, GI50 = 4 nM) and GIST-5R (cKIT T670I, GI50 = 26 nM). In the cellular context it strongly inhibited c-KIT mediated signaling pathways and induced apoptosis. In the BaF3-TEL-cKIT-T670I isogenic cell inoculated xenograft mouse model, 35 exhibited dose dependent tumor growth suppression efficacy and 100 mg/kg dosage provided 47.7% tumor growth inhibition (TGI) without obvious toxicity. We believe compound 35 would be a good pharmacological tool for exploration of the cKIT-T670I mutant mediated pathology in GISTs.

Direct reductive N-alkylation of secondary amines with carboxylic acids using molybdenum hexacarbonyl (5 mol %) as catalyst and diethoxymethylsilane as reducing agent generate enamines in a straightforward fashion in high yields. The formed enamines are without the need for isolation or purification further reacted with trimethylsilyl cyanide in the same reaction flask to yield alpha-amino nitriles in good yields. In the optimized reaction conditions equimolar amounts of carboxylic acid and amine are reacted under neat conditions, and a catalytic amount of trifluoroethanol (0.1 mol %) is added along with TMSCN for the cyanation step. The reductive N-alkylation reaction is demonstrated to be highly chemoselective, tolerating a multitude of different functional groups present in the starting carboxylic acids and amines. The reaction is scalable and the generated alpha-amino nitriles are converted to other useful compounds, e.g., alpha-amino acids or amino-tetrazoles. In addition, the intermediate enamines are further transformed into triazolines, sulfonylformamidines, pyrimidinediones, and TMS-propargylamines, respectively, in high yields under mild reaction conditions. Benzoic acids react with secondary amines under similar conditions to give tertiary amines in high yields, and using this methodology, the biologically active compound Piribedil was isolated in 80% yield in a direct one-pot reaction setup.

An assay employing a fluorescently labeled split and pool peptide library has been applied to the discovery of a new class of octapeptide catalysts for the kinetic resolution of secondary alcohols. A highly diverse library of peptide-based catalysts was synthesized on solid-phase synthesis beads such that each individual bead was co-functionalized with (i) a uniform loading of a pH-sensitive fluorophore and (ii) a unique peptidebased catalyst. The library was then screened for activity in acylation reactions employing (±)-sec-phenylethanol as the substrate and acetic anhydride as the acylation agent. From the most active catalysts, a lead peptide (4) was identified that provides a selectivity-factor (krel) of 8.2 upon resynthesis and evaluation under homogeneous conditions. A “directed” second-generation split and pool peptide library was synthesized such that the new peptide sequences in the library were biased toward the lead structure. Random samples of the second generation library were screened in single bead assays that revealed several new peptide-based catalysts that afford improved selectivities in kinetic resolutions. Peptide catalyst 13 proves effective for the kinetic resolution of sec-phenylethanol (krel = 20), as well as eight other secondary alcohols of a broad substrate scope (krel = 4 to > 50).

The reactant in an enzyme-catalyzed reaction is called a substrate. Enzyme inhibitors cause a decrease in the reaction rate of an enzyme-catalyzed reaction.I hope my blog about 2971-79-1 is helpful to your research. Synthetic Route of 2971-79-1

This manuscript reports a visible-light-mediated organosulfide catalysis that enables the decarboxylative coupling between simple aliphatic alcohol and tertiary or secondary alkyl carboxylic acid-derived redox active esters to produce a C(sp3)-O-C(sp3) fragment. Results of the coupling using other heteroatom nucleophiles such as water, amides, and thiols are also described.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Synthetic Route of 95798-23-5, you can also check out more blogs about95798-23-5

A series of novel oxazolo[5,4-d]pyrimidines was designed via a scaffold hopping strategy and synthesized through a newly developed approach. All these compounds were evaluated for their biological activity toward CB1/CB2 cannabinoid receptors, their metabolic stability in mice liver microsomes and their cytotoxicity against several cell lines. Eight compounds have been identified as CB2 ligands with Ki values less than 1 muM. It is noteworthy that 2-(2-chlorophenyl)-5-methyl-7-(4-methylpiperazin-1-yl) oxazolo[5,4-d]pyrimidine 47 and 2-(2-chlorophenyl)-7-(4-ethylpiperazin-1-yl)- 5-methyloxazolo[5,4-d]pyrimidine 48 showed CB2 binding affinity in the nanomolar range and significant selectivity over CB1 receptors. Interestingly, functionality studies imply that they behave as competitive neutral antagonists. Moreover, all tested compounds are devoid of cytotoxicity toward several cell lines, including Chinese hamster ovary cells (CHO) and human colorectal adenocarcinoma cells HT29.
