Indenestrol A (IA) is a metabolite of diethylstilbestrol (DES), and indenestrol B (IB) is an analog of IA. IA was simply obtained from E,E-dienestrol in the presence of dilute sulfuric acid, and a mixture of IA and IB was formed by thermal cyclization of E,E-dienest …

Lack of mutagenicity of diethylstilbestrol metabolite and analog, (+/-)-indenestrols A and B, in bacterial assays.
Ishikawa S, Oda T, Sato Y, Mochizuki M. Ishikawa S, et al. Mutat Res. 1996 Jul 5;368(3-4):261-5. doi: 10.1016/s0165-1218(96)90067-1. Mutat Res. 1996. PMID: 8692231
We tested the microbial mutagenicity of structural isomers of indenestrol A and indenestrol B (IB) in Salmonella typhimurium TA100 and TA98 and in Escherichia coli WP2 uvrA to investigate whether the interaction of diethylstilbestrol or IA with genomic DNA has any p …

The prostaglandin H synthase (PHS)-catalyzed metabolism of indenestrol A (IA), indenestrol B (IB) and indanestrol (I) and the effects of these compounds on PHS were studied in incubations with ram seminal vesicle microsomes (RSVM) by means of arachidonic acid (20:4) …

More recently, two closely related DES indanyl analogues have been found to differ in their interaction with PGH synthase: indenestrol A is cooxidized and activated like DES, whereas indenestrol B inhibits the enzyme. They provide useful tools to test the above hypo …
