A series of pyrazolopyrimidine mammalian Target Of Rapamycin (mTOR) inhibitors with various substituents at the 1-position have been prepared, resulting in compounds with excellent potency, selectivity and microsomal stability. Combination of a 1-cyclohexyl ketal group with a 2,6-ethylene bridged morpholine in the 4-position and a ureidophenyl group in the 6-positon resulted in compound 8a, that selectively
制备了一系列吡唑并嘧啶的哺乳动物雷帕霉素靶标(mTOR)抑制剂,这些抑制剂在1位具有多个取代基,从而产生具有出色效价,选择性和微粒体稳定性的化合物。将1-环己基缩酮基团与4-位的2,6-乙烯桥连吗啉和6-位脲基上的脲基苯基基团结合,可产生化合物8a,其在体内选择性抑制关键的mTOR生物标记至少8 h静脉给药并在异种移植肿瘤模型中显示出优异的口服活性。
