potent CCR5 antagonist, sulfoxide compound 4, mainly focusing on replacement of the [6,7]-fused 1-benzazepine nucleus. We designed, synthesized, and evaluated the biological activities of ring-expanded [6,8]-, [6,9]-, and [6,10]-fused compounds containing S-sulfoxide moieties, which led to the discovery of 1-benzazocine and 1-benzazonine compounds that exhibited potent inhibitory activities (equivalent
已对口服生物利用型有效CCR5拮抗剂亚砜化合物4进行了化学修饰,主要致力于取代[6,7]融合的1-苯并ze庚因核。我们设计,合成和评估了含有S-亚砜部分的环扩展[6,8]-,[6,9]-和[6,10]稠合化合物的生物活性,从而发现了1在结合测定法中表现出强抑制活性(相当于化合物4)的β-苯并偶氮化合物和1-苯并zon嗪化合物。另外,在融合测定中,具有S-亚砜部分((S)-(-)-5a,b,d,e)的1-苯并偶氮化合物显示出比化合物4更大的效价。从多轮感染测定法的进一步研究中发现,含有S-[((1-丙基-1H-咪唑)-5]的1-异丁基-1-苯并偶氮化合物(S)-(-)-5b -基]甲基}亚磺酰基,显示出最有效的抗HIV-1活性(在MOLT4 / CCR5细胞中,IC90 = 0.81 nM)。化合物(S)-(-)-5b(TAK-652)还抑制了外周血单核细胞(PBMC)中六种巨噬细胞嗜性(
