thymidine phosphorylase, have been identified using molecular modelling, synthesis and biological evaluation. These inhibitors are 2,4,5-trioxoimidazolidines bearing N-(substituted)phenylalkyl groups, together with, in most cases, N′-(CH2)n-carboxylic acid, ester or amide side chains. The best compound from this series is 3-(2,4,5-trioxo-3-phenylethyl-imidazolodin-1-yl)propionamide, with an IC50 of
使用分子建模,合成和生物学评估,已鉴定出血管生成酶的新型非核碱基衍生抑制剂胸苷磷酸化酶。这些抑制剂是带有N-(取代的)苯基烷基以及在大多数情况下N '-(CH 2)n-羧酸,酯或酰胺侧链的2,4,5-三氧代咪唑烷。该系列中最好的化合物是3-(2,4,5-三氧代-3-苯基乙基-咪唑啉-1-基)丙酰胺,对大肠杆菌的IC 50为40μMTP。分子建模表明,该配体与闭口的人类TP络合时,在活性位点区域的苯烷基通常被含胸腺嘧啶的结构占据。
