title: [Synthesis of ST-1435 derivatives as contraceptive for lactating women].
abstract: Four new ST-1435 derivatives 4-7 were synthesized. Both 4 and 5 are mixture of Z- and E-isomers. 4 was separated into Z- and E-isomers by spinning TLC. Their binding ability to progesterone receptor was examined and found to be less than ST-1435.
