beta-Lactam antibiotics such as the cephalosporins and penicillins have diminished clinical effectiveness due to the hydrolytic activity of diverse beta-lactamases, especially those in molecular classes A and C. A structure-activity relationship (SAR) study of a high-throughput screening lead resulted in the discovery of a potent and selective non-beta-lactam inhibitor of class C beta-lactamases.

CDC25 phosphatases are involved in deregulated cell cycle progression and tumor development with poor prognosis. Among the most potent CDC25 inhibitors, quinonoid-based derivatives have been extensively studied. Dimerisation of heterocyclic quinones has led to IRC-083864, a bis-quinone compound with increased CDC25B inhibitory activity. Thirty-one bis-thiazolone derivatives were synthesized and assayed for CDC25 inhibitory activity. Most of the dimers displayed enhanced inhibitory activities with micromolar IC50 values lower than that observed for each thiazolone scaffold separately. Moreover, most of these compounds were selective CDC25 inhibitors. Dimer 40 showed an IC50 value of 2.9 mu M and could inhibit CDC25 activity without generating reactive oxygen species which is likely to occur with quinone-based inhibitors. Molecular docking studies suggested that the dimers could bind simultaneously to the active site and the inhibitor binding pocket. (C) 2012 Elsevier Ltd. All rights reserved.

campaigns, we decided to perform a systematic study on their promiscuity. An amount of 163 rhodanines, hydantoins, thiohydantoins, and thiazolidinediones were synthesized and tested against several targets. The compounds were also characterized with respect to aggregation and electrophilic reactivity, and the binding modes of rhodanines and relatedcompounds in published X-ray cocrystal structures were analyzed
