Synthesis and in vivo evaluation of 11-substituted estradiol derivatives as anti-implantation agents
摘要:
Synthesis of 11-substituted estradiol derivatives (12-17) has been carried out by the Grignard reaction with alkyl, allyl, and benzyl halides on 17 beta-hydroxy-3-methoxy-11-oxo-estra-1,3,5(10), 8(9)-tetraene (10). The novel compounds (10 and 12-17) were evaluated for their preliminary post-coital contraceptive (anti-implantation) activity in Sprague-Dawley rats. The tested compounds were administered orally and showed significant anti-implantation activity. Compound 13 is the most potent compound in the series which showed 100% contraceptive efficacy at 1.25 mg kg (1). (c) 2008 Elsevier Ltd. All rights reserved.
