transition state analogue inhibitors of purine nucleoside phosphorylase, a therapeutic target for the control of T-cell proliferation. Immucillin analogues modified at the 2'-, 3'-, or 5'-positions of the azasugar moiety or at the 6-, 7-, or 8-positions of the deazapurine, as well as methylene-bridged analogues, have been synthesized and tested for their inhibition of human purine nucleoside phosphorylase.

氮杂-C-核苷Immucillin-H和Immucillin-G是嘌呤核苷磷酸化酶的过渡态类似物抑制剂,嘌呤核苷磷酸化酶是控制T细胞增殖的治疗靶标。已合成在氮杂嘌呤部分的2'-,3'-或5'-位或在脱氮嘌呤的6-,7-或8-位修饰的Immucillin类似物以及亚甲基桥连的类似物。并测试了它们对人嘌呤核苷磷酸化酶的抑制作用。所有类似物都是较弱的抑制剂,这反映了母体imimcillins对过渡状态特征的更好捕获。
