Biological Activity for (Z)-4-Hydroxytamoxifen

(Z)-4-Hydroxytamoxifen is an estrogen receptor antagonist (IC₅₀ = 27 μM). (Z)-4-Hydroxytamoxifen is a Tamoxifen (Cat. No. 0999) metabolite; that exhibits greater potency than the parent compound. (Z)-4-Hydroxytamoxifen also activates intein-linked inactive Cas9, reducing off-target CRISPR-mediated gene editing; system has ~25-fold higher specificity than wtCas9. (Z)-4-Hydroxytamoxifen binds to voltage-gated sodium channels, near the intracellular gate and inhibits the sodium current by delaying channel recovery from the inactivated state (IC₅₀ values are 297 nM and 2.1 µM for NavM and human Nav, respectively in HEK cells); this inhibition is independent of estrogen receptor modulation. Chemotherapeutic agent.
