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 benzaldehydederivatives as a result of
A method for producing a 1,2-benzisothiazol-3-one, having the steps of carrying out a reaction of a 2-(alkylthio)benzaldehyde with a hydroxylamine to give a 2-(alkylthio)benzaldehyde oxime and carrying out a reaction of the 2-(alkylthio)benzaldehyde oxime with a halogenating agent; and a method for producing a 1,2-benzisothiazol-3-one, having the steps of carrying out a reaction of a 2-halobenzonitrile with an alkanethiol in a heterogeneous solvent system in the presence of a base to give a 2-(alkylthio)benzonitrile and carrying out a reaction of the 2-(alkylthio)benzonitrile with an halogenating agent in the presence of water.
