Synthesis and in vitro evaluation of substituted aryl- and hetarylmethyl phosphonate and phosphate UMP derivatives as potential glucosyltransferase inhibitors
摘要:
酶β(1 [Formula: see text] 4)-葡萄糖基转移酶(BGT)催化从尿苷二磷酸葡萄糖(UDP-Glc)向双链DNA中的5-羟甲基胞嘧啶(5-HMC)碱基转移葡萄糖。通过基于结构的设计和合成,开发了潜在的BGT抑制剂。设计的抑制剂1-6提供了葡萄糖转移反应中过渡态的构象模拟。关键的合成步骤包括Michaelis-Arbuzov反应,然后与尿嘧啶-5'-morpholidophosphate耦合作为活化UMP衍生物。测试了这些化合物对BGT的体外抑制活性,并检查了抑制动力学。其中三种设计的分子被发现是BGT的潜在抑制剂,其IC50值在微摩尔(µM)范围内。建立了有用的结构-活性关系,为设计未来的BGT抑制剂提供了指导。关键词:β-葡萄糖基转移酶,过渡态,酶抑制剂,基于结构的设计,合成。

A novel class of glucosyltransferase inhibitors has been designed and synthesised. The designed inhibitors 1-4 provide conformational mimicry of the transition-state in glucosyltransfer reactions. The key synthetic steps involve a Michaelis-Arbuzov reaction followed by coupling with uridine-5'-morpholidophosphate as activated UMP derivative. (C) 2001 Elsevier Science Ltd. All rights reserved.
