the linker sulfone of R-bicalutamide was maintained or replaced with several alternative linkages including ether, amine, N-methylamine, thioether, and methylene (in this case the product was a racemic mixture) functional groups at the X-position. To expand the structure-activity relationship (SAR) of these arylisothiocyanato AR ligands, B-ring halogenated arylisothiocyanato ligands were also prepared
制备了一系列新的雄激素受体靶向剂(ARTA),并在雄激素依赖性和非依赖性前列腺癌细胞系中进行了测试。这些试剂是具有异硫氰酸根基取代的B环的比卡鲁胺类似物。同样,R-比卡鲁胺的连接基砜被保持或替换为几个可选的连接基,包括醚,胺,N-甲胺,硫醚和亚甲基(在这种情况下,该产品是外消旋混合物)在X位置的官能团。为了扩大这些芳基异硫氰酸根基AR配体的结构活性关系(SAR),还制备并测试了B环卤代芳基异硫氰酸根基配体。芳基异硫氰酸根基AR配体对AR的结合亲和力范围为0.6到54 nM。其中,硫醚和醚键表现出高结合亲和力(0.6和4.6 nM,与雄激素非依赖性前列腺癌细胞系(DU145,PC-3和PPC-1)相比,对LNCaP(一种雄激素依赖性前列腺癌细胞系)分别具有选择性和选择性的细胞生长抑制作用(约3至6倍),并且膀胱细胞系(TSU-Pr1)。但是,配体在正常猴肾细胞系(CV-1)中是无活性的(IC50>
