Abstract

A series of 2-(hydrazinocarbonyl)-3-aryl-1H-indole-5-sulfonamides has been derivatized by reaction with 2,4,6-trimethylpyrylium perchlorate, leading to pyridinium derivatives. The new sulfonamides were evaluated as inhibitors of two beta-carbonic anhydrases (CAs, EC 4.2.1.1) from Mycobacterium tuberculosis, Rv1284 and Rv3273. The whole series showed excellent nanomolar inhibitory activity, with several subnanomolar inhibitors being detected. Rv1284 and Rv3273 have potential for developing antimycobacterial agents with an alternate mechanism of action.
