Abstract:
:2-methoxyestradiol is a novel agent showing both anti-angiogenic and vascular disrupting properties. In this study, a series of 11α-substituted 2-methoxyestradiol analogs have been designed and synthesized targeting dual ERα and microtubulin. Biological evaluation was performed on their anti-proliferative activities against 5 different cell lines. The results indicated that most compounds exhibited good activities, in which compound 24c and 30c showed the best activity with low micromolar IC50 (2.73 μM -7.75 μM) in all cell lines. The investigation of ER affinity showed that the majority of the compounds displayed good activity at the concentration of 50 μM. In further mechanism study, it was observed that 24c and 30c could induce G2/M cell cycle arrest as well as significant anti-estrogenic activity. In CAM assay, compound 24c and 30c presented significantly anti-angiogenesis activity comparable with 2-methoxyestradiol. Overall, based on biological activities data, 24c and 30c can be identified as a potential lead molecule which might be of therapeutic importance for cancer treatment.
