Abstract

Adenylat kinase is an ubiquitous enzyme found in prokaryotes and eukaryotes. In the present study we examined the inhibition of Streptococcus pneumoniae adenylate kinase (AKSP) by six 5-arylidene-thiazolidin-4- on-2-thione derivates using 2, 4-dinitrophenylhydrazine colorimetric assay. Inhibition of AKSP activity with synthetic compounds was performed against recombinant enzyme over-expressed in E. coli. The compound C10H6BrNOS2 with the bromine atom in -ortho position has shown the most efficient inhibitory activity; I50 value (the inhibitor concentration that leads to 50% activity inhibition) was 0.067mM.
