In an effort to develop potent human purine nucleoside phosphorylase (PNP) inhibitors as immunosuppressive and chemotherapeutic agents, several 8-aminoguanine derivatives were synthesized and evaluated as potential PNP inhibitors. These studies were designed to investigate the hydrophobic effect of a substituent on the N-9 of the purine heterocycle and/or the C-5' positions. Compounds such as 8-aminoguanosine
为了开发有效的人嘌呤核苷磷酸化酶(PNP)抑制剂作为免疫抑制剂和化学治疗剂,合成了几种8-氨基鸟嘌呤衍生物并将其评估为潜在的PNP抑制剂。这些研究旨在研究取代基对嘌呤杂环的N-9和/或C-5'位置的疏水作用。合成了含有对-(氟磺酰基)苯甲酰基部分的化合物,例如8-氨基鸟苷,鸟苷,甲霉素B和8-氨基无环鸟苷。确定了这些化合物对红细胞PNP的亲和力,并且这些化合物均未显示出比母体化合物更好的亲和力。但是,我们发现在N-9和C-5'位置的疏水作用可能在与PNP活性位点结合中起重要作用。因此,8-amino-5'
