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.

A series of nifuroxazide analogues [(2a-2e)-(10a-10f)] have been synthesized, structurally identified and tested for antimicrobial activity against a panel of bacteria (Gram-positive and Gram-negative) and the yeast-like pathogenic fungus Candida albicans. The most active compound in this series was 4-amino-benzoic acid (5-nitro-furan-2-ylmethylene)-hydrazide (2b) and 2-amino-benzoic acid (5-nitro-furan-2-ylmethylene)-hydrazide (2d). Furthermore, compounds (9a-9g) and (10a-10g) recorded no activity against selected species except compounds (9f) and (10f) suggesting that using furoic hydrazide and the corresponding hydrazide of thiophene did not improve the antimicrobial activities for this type of compounds. Regarding the activity against Candida albicans, all compounds showed no activity with an exception of substituted nitro furan (2a-2d).
