Biological Data

Biological description

Estrogen receptor antagonist and partial agonist. It is also a potent chloride channel HSV-1 inhibitor. It is blood brain barrier permeable.

Tamoxifen inhibits tumor growth and induces apoptosis in breast cancer cells. It also selectively inhibits sterol biosynthesis (IC50 = 1000 nM) and shows neuroprotective potential.

It is used in gene editing in which tamoxifen (Tm)-inducible Cre recombinases are widely used to perform gene inactivation and lineage tracing studies in mice.

It can also switch on the inducible CRISPR-Cas9 system (iCas).
