2), an osteoporosis drug that decreases bone resorption by inhibiting farnesyl pyrophosphate synthase (FPPS) in osteoclasts, preventing protein prenylation. 1 has lower bone affinity than 2 and weakly inhibits Rab geranylgeranyl transferase (RGGT), selectively preventing prenylation of Rab GTPases. We report here the synthesis and biological studies of 2-hydroxy-3-imidazo[1,2-a]pyridin-3-yl-2-phosphonopropionic
3-(3-吡啶基)-2-羟基-2-膦酰基丙酸(3-PEHPC,1)是2-(3-吡啶基)-1-羟基亚乙基双(膦酸)(雷司膦酸,2),一种骨质疏松药物,通过抑制破骨细胞中的法呢基焦磷酸合酶(FPPS)来降低骨吸收,从而防止蛋白质异戊二烯化。1具有比2低的骨亲和力,并且弱抑制Rab geranylgeranyl转移酶(RGGT),选择性地阻止Rab GTPases的异戊二烯化。我们在这里报告2-羟基-3-咪唑并[1,2- a ]吡啶-3-基-2-膦酰基丙酸(3-IPEHPC,3),米诺膦酸4的PC类似物的合成和生物学研究。喜欢1,3选择性抑制Rab11与在J774细胞说唱1A异戊二烯化,和降低的细胞活力,但33-60×在这些测定中更有活性。通过手性HPLC(> 98%ee)拆分3后,我们发现,在单独的RGGT抑制试验中,(+)- 3 -E1比(-)- 3 -E2更有效,〜17×更有力(LED 3
