A series of triarylethylene compounds related to 4-hydroxyclomiphene (2) in which the vinyl Cl substituent was replaced by ethyl (5), Br (6), H (7), CN (8), or NO2 (9) substituents were synthesized to facilitate studies of the molecular actions of synthetic nonsteroidal antiestrogens. The relative
Current therapies for estrogen receptor-positive (ER+) cancers rely heavily on growth prevention by cytostatic agents rather than destruction of the cancer cells. In these studies, we compared the tissue distribution of two radioiodinated estrogens, one a triphenylethylene estrogen, IBHPE, the other
Howiinol A (GHM-10) is a kind of phenylethylene pyrone compounds isolated from Goniothalamus howii. By using the techniques of cell growth curve determination, MTT test, soft agar colony assay and experimental therapy of transplantable tumors in mice, it is found that GHM-10 exerts potent inhibitory
The diastereomeric 1-(fluoro/difluorophenyl)-2-phenylethylene-diamines (4-fluoro: erythro-1/threo-1; 2,4-difluoro: erythro-2/-threo-2; 2,6-difluoro: erythro-3/threo-3) and the diastereomeric 1-(4-fluorophenyl)-2-(3-hydroxyphenyl)ethylenediamines (erythro-4/-threo-4) were synthesized from
Organometallic ruthenium(II) arene complexes containing the PTA ligand ([Ru(η(6)-arene)Cl(2)(PTA)], PTA = 1,3,5-triaza-7-phosphatricyclo-[3.3.1.1]decane, termed RAPTA) show pharmacologically relevant anti-tumour properties in vitro. Two new enantiomeric pairs of RAPTA compounds, containing the
