Inhibitors of squalene synthase have the potential to be superior cholesterol-lowering agents. We previously disclosed that lipophilic 1,1-bisphosphonates I are potent squalene synthase inhibitors and orally active cholesterol-lowering agents in animal models (Ciosek, C. P., Jr.; et al. J. Biol. Chem. 1993, 268, 24832-24837). In this paper, we describe modifications to the bisphosphonate moiety, in
角鲨烯合酶的抑制剂有可能成为优异的降胆固醇药。我们先前曾披露亲脂性1,1-双膦酸酯I在动物模型中是有效的角鲨烯合酶抑制剂和口服活性降胆固醇剂(Ciosek,CP,Jr .; et al.J.Biol.Chem.1993,268,24832-24837 )。在本文中,我们描述了对双膦酸酯部分的修饰,以尝试减少这些抑制剂中所含的酸性功能。当与自然存在的法呢基部分的近似模拟物配对时(R1 =法呢基乙基),而与较短的异戊二烯替代物配对时(R1 =香叶基乙基),用甲基(II,R2 = CH3)取代一个酸性基团会产生有效的抑制剂或4-联苯丙基)。相反,所有三种相应的双膦酸酯I都是有效的角鲨烯合酶抑制剂。当R2为CH2OH或CH2OCH3时,用较短的异戊二烯替代物可恢复抑制能力。提出这些R 2基团充当酶的活性位点的氢键受体。描述了这些化合物在大鼠中作为胆固醇生物合成抑制剂的特性,并详细说明了这些化合物和相关化合物的合成途径。
