Abstract: This invention describes the new triphenylethylenes of general formula I ##STR1## in which n means an integer from 1 to 10,R' means a sulfur-containing organic radical,R" means a hydrogen atom, an iodine atom or a hydroxy groups,E means a hydrogen atom,G means a hydrogen atom orE and G together mean a methylene bridge.The new compounds have strong antiestrogenic properties and are suitable for the production of pharmaceutical agents, for example for treating breast cancer.

Abstract: The invention relates to new leukotriene-B.sub.4 analogs of formula I, ##STR1## in which R.sub.1 means radicals CH.sub.2 OH, CH.sub.3, CF.sub.3, COOR.sub.4, or radical CONHR.sub.5,A means a trans, trans--CH.dbd.CH--CH.dbd.CH-- group, trans--CH.sub.2 --CH.sub.2 --CH.dbd.CH-- group or tetramethylene group,B means a straight-chain or branched-chain, saturated or unsaturated alkylene group with up to 10 C atoms,D means a direct compound, oxygen, sulfur, a --C.tbd.C--group or a --CH.dbd.CR.sub.6 --group,B and D together mean a direct bond,R.sub.2 means a hydrogen atom or an acid radical of an organic acid with 1-15 C atoms andR.sub.3 means a hydrogen atom, an optionally substituted alkyl radical with 1-10 C atoms, a cycloalkyl radical with 3-10 C atoms, an optionally substituted aryl radical with 6-10 C atoms or a 5-6-member heterocyclic radical and, if R.sub.
