Our continuing program to develop new antifolate drugs useful against rheumatoid arthritis led us to modify the pteridine ring of gamma-fluoromethotrexate. Pyrrolopyrimidine derivatives 1e and 1t were found to exhibit potent suppressive effects on the responses of both T and B cells to mitogens, although tetrahydropyridopyrimidine derivatives 2e and 2t and quinazoline derivatives 3e, 3t and 4e showed
我们不断开发可用于治疗类风湿性关节炎的抗叶酸药物的计划使我们修改了γ-氟代甲氨蝶呤的蝶啶环。尽管四氢吡啶并嘧啶衍生物2e和2t以及喹唑啉衍生物3e,3t和4e显示出非常弱的抑制活性,但发现吡咯并嘧啶衍生物1e和1t对T和B细胞对促细胞分裂剂的反应均显示出强抑制作用。因此,γ-氟代甲氨蝶呤的蝶啶环向吡咯并嘧啶环的转化导致了新的潜在的抗风湿性化合物。
