  Benzo[d]imidazole Transient Receptor Potential Vanilloid 1 Antagonists for the Treatment of Pain: Discovery of trans-2-(2-{2-[2-(4-Trifluoromethyl-phenyl)-vinyl]-1H-benzimidazol-5-yl}-phenyl)-propan-2-ol (Mavatrep)

  摘要：

  Reported herein is the design, synthesis, and Pharmacologic characterization of a class of TRPV1 antagonists constructed on a benzo[d]imidazole platform that evolved from a biaryl amide lead. This design composes three sections: a 2-substituted 5-phenyl headgroup attached to the benzo [d]imidazole platform, which is tethered at the two position to a phenyl tail group. Optimization of this design led to the identification of 4 (mavatrep), comprising a trifluoromethyl-phenyl-vinyl tail. In a TRPV1 functional assay, using cells expressing recombinant human TRPV1 channels, 4 antagonized capsaicin-induced Ca2+ influx, with an IC50 value of 4.6 nM. In the complete Freund's adjuvant- and carrageenan-induced thermal hypersensitivity models, 4 exhibited full efficacy, With ED80 values of 7.8 and 0.5 mg/kg, respectively, corresponding to plasma levels of 270.8 and 9.2 ng/mL, respectively. On the basis of its superior pharmacologic and safety profile, 4 (mavatrep) was selected for clinical development for the treatment of pain.

  使用多金属氧酸盐负载的铬（III）催化剂和CO2将醇高效氧化为羧酸

  摘要：

  将醇直接催化氧化为羧酸非常有吸引力，但是尚未建立经济的催化体系。在这里，我们显示纯的无机配体负载的铬化合物（NH 4）3 [CrMo 6 O 18（OH）6 ]（简化为CrMo 6）可用于在存在以下条件下有效地促进此类反应CO 2。在几乎所有情况下，各种醇（芳香族和脂肪族）的氧化都可以在温和的条件下完成，相应的羧酸可以高收率实现。铬催化剂1可以重复使用几次，而不会造成活动损失。机理研究和控制反应表明，酸化是通过醛的关键氧化立即进行的。

  A silver‐mediated oxidative difluoromethylation of styrenes and vinyl trifluoroborates with TMSCF2H is reported for the first time. This method enables direct and facile access to CF2H‐alkenes from abundant alkenes with excellent functional‐group compatibility. Moreover, this Ag/TMSCF2H protocol could further enable a series of radical difluoromethylation reactions of a wide array of substrates, offering
