In ?-proteobacteria and Actinomycetales, cysteine biosynthetic enzymes are indispensable during persistence and become dispensable during growth or acute infection. The biosynthetic machinery required to convert inorganic sulfur into cysteine is absent in mammals; therefore, it is a suitable drug target. We searched for inhibitors of Salmonella serine acetyltransferase (SAT), the enzyme that catalyzes the rate-limiting step of l-cysteine biosynthesis. The virtual screening of three ChemDiv focused libraries containing 91 ?243 compounds was performed to identify potential SAT inhibitors. Scaffold similarity and the analysis of the overall physicochemical properties allowed the selection of 73 compounds that were purchased and evaluated on the recombinant enzyme. Six compounds displaying an IC50 a Gram-negative model organism, with one of them being able to interfere with bacterial growth via SAT inhibition.

With the goal of obtaining new ethylenedithiolate transition metals complexes, unstable tetrabutylammonium bis(1,3-dithiol-4,5-dithiolato)niccolate(III) and stable tetrabutylammonium bis(5,6-dihydro-1,4-diselenin-2,3-dithiolato)niccolate(III) were synthesized. The two complexes were characterized by elemental analysis and IR and electron absorption spectroscopy, and the second, also by voltammetry. A new convenient procedure was proposed for preparation of 1,3-dithiol-2-thione which is a key initial compound in the synthesis of the title complexes.
