== Publication Abstract from PubMed ==
Recognizing acetyllysine of histone is a vital process of epigenetic regulations, which is mediated by a protein module called bromodomain. To contribute novel scaffolds for developing into bromodomain inhibitors, we utilize a fragment-based drug discovery approach. By successively applying docking and X-ray crystallography, we were able to identify 9 fragment hits from diffracting more than 60 crystals. In the present work, we described four of them, and carried out the integrated lead optimization for fragment 8, which bears a 2-thiazolidinone core. After several rounds of structure guided modifications, we assessed the druggability of 2-thiazolidinone by modulating in vitro pharmacokinetic studies and cellular activity assay. The results showed that two potent compounds of 2-thiazolidinones have good metabolic stability. Also the cellular assay confirmed the activities of 2-thiazolidinones. Together, we hope the identified 2-thiazolidinone chemotype as well as other fragment hits described herein, can stimulate researchers to develop more diversified bromodomain inhibitors.
