Jan 21, 2014 · ICI 182,780 (ICI, fulvestrant, Faslodex) is an estrogen receptor antagonist, as binding to ERα causes a conformational change disabling both AF-1 and AF-2. Furthermore, the ICI–ERα complex is unstable, resulting in accelerated degradation of the ERα protein (20). A transcriptomics model of estrogen action in the ovine fetal hypothalamus: evidence for estrogenic effects of ICI 182,780.

Moreover, ICI 182,780 had poor efficacy in blocking tamoxifen actions in T3-dependent responses. The results indicate that ICI 182,780, like tamoxifen, displays a duality in its pharmacological behavior which pivots on the T3 dependence of the estrogen response.

1) It is bound by estrogen receptors with a high affinity, similar to that for estradiol. 2) It is a "pure" antiestrogen in that it does not mimic any of the effects of estradiol. ICI 182,780 was a more effective inhibitor of MCF-7 growth than 4'-hydroxytamoxifen, producing an 80% reduction of cell number under conditions where 4'-hydroxytamoxifen achieved a maximum of 50% inhibition.

ICI 182,780 has agonistic effects and synergizes with estradiol-17 beta in fish liver, but not in testis

Treatment with ICI 182780 also resulted in a significant reduction in pS2 expression ( P < 0.05) but this appeared unrelated to tumor ER status. In conclusion, ICI 182780 was well tolerated after short term administration and produced demonstrable antiestrogenic effects in human breast tumors in vivo , without showing evidence of agonist activity. The pure antiestrogen ICI 182,780 binds to the estrogen receptor with high affinity and is currently in clinical trials for the treatment of human breast cancer. We now show for the first time that ICI 182,780 also exhibits potent antiprogestin activity at doses frequently used in laboratory investigations. The antiprogestin activity of ICI 182,780 was detected in HeLa, HepG2, and CV1 cells The effects of the anti‐estrogens 4‐hydroxytamoxifen (OHTam), ICI 164,384 and ICI 182,780 were tested on the MCF‐7/LCC2 breast‐carcinoma cell line, which grows significantly in the presence of OHTam and serves as a model for studying anti‐estrogen resistance of estrogen‐receptor‐positive breast cancer.

ICI 182,780 increased the open probability of BK(Ca) channels in inside-out patches with an EC(50) of 1 microM. These data suggest that molecules with the ability to bind nuclear estrogen receptors, regardless of oestrogenic or anti-estrogenic nature, activate BK(Ca) channels through this nongenomic, membrane-delimited mechanism. ICI 182,780 was a more effective inhibitor of MCF-7 growth than 4′-hydroxytamoxifen, producing an 80% reduction of cell number under conditions where 4′-hydroxytamoxifen achieved a maximum of 50% inhibition.
