bicalutamide (IC50 = 45.20 –51.61 µM) and enzalutamide (IC50 = 11.47 – 53.04 µM). Sulfoxide derivatives of bicalutamide were prepared efficiently from the corresponding sulfides using only one equivalent of mCPBA, limiting the reaction time to 15–30 min and maintaining the temperature at 0 °C. Interestingly, three pairs of sulfoxide diastereomers were separated and NMR comparison of their diastereotopic methylene
雄激素受体 (AR) 是治疗前列腺癌 (PC) 的关键靶标,即使该疾病进展为不依赖雄激素或去势抵抗的形式。在这项研究中,制备了一系列亚砜衍生物,并在体外评估了它们对四种不同的人前列腺癌细胞系(22Rv1、DU-145、LNCaP 和 VCap)的抗增殖活性。比卡鲁胺和恩杂鲁胺用作阳性对照。化合物28显示的显著增强在抗癌活性在四个PC细胞系IC 50 = 9.09 - 31.11μM相比,阳性对照:比卡鲁胺(IC 50 = 45.20 -51.61μM )和enzalutamide(IC 50 = 11.47 – 53.04 µM)。比卡鲁胺的亚砜衍生物仅使用一当量的m CPBA从相应的硫化物有效制备,将反应时间限制在 15-30 分钟,并将温度保持在 0 °C。有趣的是,分离了三对亚砜非对映异构体,并提供了它们非对映异构亚甲基 (CH 2 ) 基团的NMR 比较。X 射线衍射晶体结构分
