In addition, some estro-gen receptor ligands such as droloxifene have beenshown to inhibit the growth of cultured rat luteal cells.It has been known that 2-phenylindole derivatives couldcompete with estradiol for the estrogen receptor. Theseresults prompted us to design and synthesize the follow-ing six new 3-oxamoyl-2-phenylindole compounds 1a-fand test their effects on the growth of luteal cells, aimingat seeking new lead compounds possessing antifertility activities.展开更多
