A novel series of 17-modified and 2,17-modified analogs of 2-methoxyestradiol (2ME2) were synthesized and characterized. These analogs were designed to retain or potentiate the biological activities of 2ME2 and have diminished metabolic liability. The analogs were evaluated for antiproliferative activity against MDA-MB-231 breast tumor cells, antiangiogenic activity in HUVEC, and estrogenic activity
合成和表征了一系列新的17-修饰和2,17-修饰的
2-甲氧基雌二醇(2ME2)类似物。这些类似物旨在保留或增强2ME2的
生物学活性,并减少了代谢功能。评价类似物对
MDA-MB-231乳腺肿瘤细胞的抗增殖活性,HU
VEC中的抗血管生成活性以及对MCF-7细胞增殖的
雌激素活性。在大鼠盒给药模型中,评估了几种类似物在人肝微粒体中和体内的代谢稳定性。这项研究导致了2ME2的17个修饰的类似物,与2ME2相比,它们具有相似或改善的抗增殖和抗血管生成活性,缺乏
雌激素特性并具有改善的代谢稳定性。
