 Use of Endoxifen (E-isomer)


Endoxifen E-isomer is the E-isomer of (Z)-Endoxifen. (Z)-Endoxifen, an active metabolite generated via actions of CYP3A4/5 and CYP2D6, is a more potent selective estrogen receptor modulator (SERM) than Tamoxifen.

 Endoxifen (E-isomer) Biological Activity

Description Endoxifen E-isomer is the E-isomer of (Z)-Endoxifen. (Z)-Endoxifen, an active metabolite generated via actions of CYP3A4/5 and CYP2D6, is a more potent selective estrogen receptor modulator (SERM) than Tamoxifen.

In Vitro Endoxifen exists as the potently anti-estrogenic (Z)-isomer and the lesser known (E)-isomer. It is assumed that (E)-Endoxifen, structurally related to (E)-4-OH-tamoxifen, have similar pharmacological properties. The (E)-isomer is an impurity in (Z)-Endoxifen drug substance and increases under certain storage conditions. (E)-Endoxifen is identified as the primary degradant[1].
