synthesized as selective farnesyltransferase inhibitors using structure-based design. X-ray cocrystal structures of compound 20-FTase-HFP and A313326-FTase-HFP confirmed our initial design. The decreased interaction between the aryl groups and Ser 48 in GGTase-I binding site could be one possible reason to explain the improved selectivity for this new series of FTase inhibitors. Medicinal chemistry efforts
已经使用基于结构的设计合成了一系列新型的4-[(4-氰基-2-芳基苄氧基)-(3-甲基-3H-咪唑-4-基)甲基]苄腈作为选择性的法呢基转移酶抑制剂。化合物20-FTase-HFP和A313326-FTase-HFP的X射线共晶体结构证实了我们的初步设计。在GGTase-I结合位点中,芳基与Ser 48之间相互作用的减少可能是解释这种新系列FTase抑制剂选择性提高的可能原因。药物化学作用导致发现了具有强细胞活性(EC(50)= 3.5 nM)和杰出的药代动力学特征的化合物64(生物利用度96%,口服t(1/2)为18.4 h,0.19 L /(hx) kg)血浆清除率)。
