Abstract
5- Substituted 2,3,4,5- Tetrahydro- 1-benzoxepine derivatives have been synthesized as novel antiimplantation agents. The synthesized compounds were evaluated for their anti-implantation activity in mature female Sprague-Dawley rats. The most active compounds in this series 10d and 11d, are 67% active in preventing implantation in rats at 10 mgkg-1 dose. We also found that the other compounds of the series have lesser anti-implantation activity compared to the most potent anti-implantation drug Centchroman 5.
