Tipidogrel (3), an effective anti-platelet drug candidate working by irreversibly inhibiting P2Y12 receptor, holds great promise in overcoming clopidogrel resistance and increasing bioavailability. As a prodrug like other thienopyridines, it metabolizes through thiophene ring opening to form active metabolites 3a and 3b, nevertheless they are easily to form disulfide bond. Derivatization of 3a and 3b via alkylation with MPBr can prevent disulfide conjugation and ensure reliable pharmacokinetic results. Thus, in order to support its pre-clinical studies on efficiencies in the formation of tipidogrel active metabolites, 13a and 13b were synthesized via seven steps of chemosynthesis and incubation with MPBr in rat plasma in vitro. The resulting crude productions were purified by semi-preparative HPLC to give Z configuration 13a and E configuration 13b. In LC-MS/MS spectra, they showed identical fragmentation pattern and retention time with M-13a and M-13b, the MPBr-derivatives of active metabolites of tipidogrel in rats. Thus, 13a and 13b were the anticipated alkylated active metabolite of tipidogrel. In addition, in the nucleophilic substitution of thioacetate with compound 11, besides the anticipated compounds 12a and 12b, their isomers compounds 12c and 12d were detected, whose structures were confirmed and the corresponding mechanism was presented.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 41661-47-6 is helpful to your research. Computed Properties of C5H9NO

Direct inhibition of coagulation factor Xa (FXa) carries significant promise for developing effective and safe anticoagulants. Although a large number of FXa inhibitors have been studied, each can be classified as either possessing a highly flexible or a rigid core scaffold. We reasoned that an intermediate level of flexibility will provide high selectivity for FXa considering that its active site is less constrained in comparison to thrombin and more constrained as compared to trypsin. We studied several core scaffolds including 1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid for direct FXa inhibition. Using a genetic algorithm-based docking and scoring approach, a promising candidate 23 was identified, synthesized, and found to inhibit FXa with a Ki of 28 muM. Optimization of derivative 23 resulted in the design of a potent dicarboxamide 47, which displayed a Ki of 135 nM. Dicarboxamide 47 displayed at least 1852-fold selectivity for FXa inhibition over other coagulation enzymes and doubled PT and aPTT of human plasma at 17.1 muM and 20.2 muM, respectively, which are comparable to those of clinically relevant agents. Dicarboxamide 47 is expected to serve as an excellent lead for further anticoagulant discovery.

Diarylalkynes are readily transformed in 3-chlorobenzo[b]thiophenes in a two-step electrophilic addition-cyclization procedure that runs highly efficiently in solution or in the solid phase. The heteroaromatic carbon-chlorine bond participates in palladium-catalyzed Suzuki-Miyaura or Buchwald-Hartwig cross-couplings to give, in a single step, 2,3-disubstituted derivatives of pharmacological relevance.

A series of coumarin and quinolinone-3-aminoamide derivatives was synthesized and evaluated for its potency in inhibition of cancer cell growth. The structure of N-[2-(dimethylamino) ethyl]-4-hydroxy-2-oxo-1-phenyl-1,2- dihydroquinoline-3-carboxamide was unambiguously confirmed by X-ray diffraction analysis, which revealed the cis conformation of the amide bond resulting from the presence of two intramolecular hydrogen bonds.

The bromodomain and extra-terminal domain (BET) family of proteins are readers which specifically recognize histone-acetylated lysine residues. Each BET bromodomain protein contains two highly homologous domains: the first bromodomain (BD1) and the second bromodomain (BD2). Pan-BET bromodomain inhibition is a potential therapy for various cancers and immune-inflammatory diseases, but only few reported inhibitors show selectivity within the BET family. Herein, we identified a series of benzo[cd]indol-2(1H)-ones and pyrrolo[4,3,2-de]quinolin-2(1H)-ones with good selectivity for BET BD1. Through structure-based optimization, highly active and selective compounds are ultimately obtained. The representative compounds are the first reported inhibitors with selectivity more than 100-fold for BRD4(1) over BRD4(2). Among them, we further show that 68 (LT052) mediates BRD4/NF-kappaB/NLRP3 signaling inflammatory pathways with comparable protein expression and significantly improves symptoms of gout arthritis in a rat model. Therefore, selective pharmacological modulation of individual bromodomains could represent a strategy for the treatment of acute gouty arthritis.
