  Synthesis and structure–activity relationships of second-generation hydroxamate botulinum neurotoxin A protease inhibitors

  摘要：

  Botulinum neurotoxins are the most toxic proteins currently known. Based on a recently identified potent lead structure, 2,4-dichlorocinnamic acid hydroxamate, herein we report on the structure- activity relationship of a series of hydroxamate BoNT/A inhibitors. Among them, 2-bromo-4-chlorocinnamic acid hydroxamate, 2-methyl-4-chlorocinnamic acid hydroxamate, and 2-trifluoromethyl-4-chlorocinnamic acid hydroxamate displayed comparable inhibitory activity to that of the lead structure.

  functionalized benzaldehydes under mild conditions. This reaction was promoted specifically by a low-cost and simple CrCl2 salt used as a precatalyst, enabling synchronous activations of ortho-C(aryl)–SMe and ortho′-C(aryl)–H bonds to achieve difunctionalization of benzaldimines. This work provided a strategy for accessing arylated, alkylated, and diarylated benzaldehyde derivatives as a result of

  这里描述的是铬催化的 C(芳基)-SMe 键断裂，导致在温和条件下与有机镁偶联得到官能化苯甲醛。该反应通过一种用作预催化剂的低成本且简单的 CrCl 2盐来特别促进，使邻-C(芳基)-SMe 和邻'-C(芳基)-H 键同步活化以实现苯扎亚胺的双官能化。由于 C(芳基)-SMe 和 C(芳基)-SMe/C(芳基)-H 键的偶联在具有成本效益的 Cr 催化作用下得到促进，这项工作提供了一种获取芳基化、烷基化和二芳基化苯甲醛衍生物的策略.
