The present invention is novel derivatives of pyrrolo[3,2-d]pyrimidines and pharmaceutical compositions and methods of use therefor. The derivatives are inhibitors of purine nucleoside phosphorylase selectively cytotoxic to T-cells but not to B-cells in the presence of 2'-deoxyguanosine and, therefore, are for use in the treatment of autoimmune diseases, gout, psoriasis or rejection of transplantation.
本发明涉及新型
吡咯[3,2-d]
嘧啶衍
生物及其制药组合物和使用方法。这些衍
生物是
嘌呤核苷酸
磷酸化酶的
抑制剂,在存在2'-去氧
鸟苷的情况下,对T细胞具有选择性细胞毒性,而不对B细胞产生细胞毒作用,因此可用于治疗自身免疫性疾病、痛风、牛皮癣或移植排斥反应。
