Design, syntheses and evaluation of 4-oxo-5-cyano thiouracils as SecA inhibitors
摘要:
Protein translocation is essential for bacterial survival and the most important translocation mechanism is the secretion (Sec) pathway in which SecA is a central core driving force. Thus targeting SecA is a promising strategy for developing novel antibacterial therapeutics. Herein, we report the syntheses and evaluation of a series of nearly 60 4-oxo-5-cyano thiouracil derivatives based upon our previously reported core pyrimidine structure. Introduction of polar group such as -N-3 and linker groups such as -CH2-O- enhanced the potency several fold. Apart from being potential antibacterial agents, these inhibitors can be indispensable tools for biologists to probe the mechanism of protein translocation via the SecA machinery in bacteria. Published by Elsevier Ltd.
SecA ATPase is a critical member of the Sec family, which is important in the translocation of membrane and secreted polypeptides/proteins in bacteria. Small molecule inhibitors can be very useful research tools as well as leads for future antimicrobial agent development. Based on previous virtual screening work, we optimized the structures of two hit compounds and obtained SecA ATPase inhibitors with IC50 in the single digit micromolar range. These represent the first low micromolar synthetic inhibitors of bacterial SecA and will be very useful for mechanistic studies. (C) 2010 Elsevier Ltd. All rights reserved.
