title: Synthesis and antimitotic activity of novel 2-methoxyestradiol analogs.
abstract: The syntheses and antimitotic activity of several novel 2-methoxyestradiol analogs are described. Structural modifications investigated include introduction of additional unsaturation in rings B and D; inversion at C-13; and substitution at the C-2, C-15, C-16, and C-7 alpha positions. Of 15 analogs synthesized, 2 have demonstrated superior biological activities compared to 2-methoxyestradiol.
