A series of 17 novel 2-amino-4-oxo-5-[(substituted phenyl)thio]pyrrolo[2,3-d]pyrimidines were synthesized as potential inhibitors of thymidylate synthase (TS) and as antitumor agents. The analogues contain a variety of electron withdrawing substituents on the phenyl ring of the side chain and were evaluated as inhibitors of human TS (hTS) and Escherichia coli TS and of human and E. coli dihydrofolate
合成了17种新颖的2-氨基-4-氧代-5-[(取代的苯基)硫代]吡咯并[2,3-d]嘧啶类化合物,作为胸苷酸合酶(TS)的潜在抑制剂和抗肿瘤剂。该类似物在侧链的苯环上包含各种吸电子取代基,被评估为人类TS(hTS)和大肠杆菌TS以及人类和大肠杆菌二氢叶酸还原酶(DHFR)的抑制剂。类似物14、17和18是hTS的有效抑制剂,IC50值分别为0.28、0.21和0.22 microM,并且比临床使用的ZD1694、2和LY231514、3对人TS的抑制作用更强。
