molecules capable of inhibiting transcription initiation in bacteria has resulted in the synthesis of N,N′-disubstituted hydrazines and imine-carbohydrazides comprised of indole, pyridine, pyrrole, furan and thiophene using the respective trichloroacetyl derivatives, carbohydrazides and aldehydes. Replacement of the indole moiety by smaller heterocycles linked by CONHNC linkers afforded a broad variety

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.

so far. We describe a novel platform by which an inhibitor was selected out of around 185 compounds directly from reaction media containing thiosemicarbazones and mono-, di-, and trihydrazones. To achieve this, tandem library preparation, thin-layer chromatography (TLC) bioautography, and effect-directed deconvolution were applied. We illustrate the potential of this effect-directed synthesis for the
