A systematically generated series of hydrazones were analyzed as potential inhibitors of anthrax lethal factor. The hydrazones were screened using one UV-based and two fluorescence-based in vitro assays. The study identified several inhibitors with IC50 values in the micromolar range, and importantly, significant differences in the types of inhibition were observed with the different assays.

Abstract The reaction of nicotinic and isonicotinic acidhydrazides with o-formyl benzoic acid in ethanol led to the formation of the corresponding hydrazones. It was found that o-formyl benzoic acid reacted in aldehyde form with hydrazides to form hydrazones. When heated in acetic anhydride, the latter are smoothly cyclized into 3-acetoxyisoindolin-1-ones. Structure of the synthesized compounds was
