Description

Biochem/physiol Actions

2,3′,4,5′-Tetramethoxystilbene, also known as TMS, is a selective and competitive inhibitor of cytochrome P450 1B. It is a synthetic trans-stilbene analog. TMS is an analog of resveratrol and is an anti-cancer agent. TMS is cytotoxic to gefitinib-resistant (G-R) non-small-cell lung cancer (NSCLC) cells. It binds to sarco/endoplasmic reticulum Ca²⁺-ATPase (SERCA) and promotes apoptosis and autophagy. TMS is also a selective inhibitor of CYP1B1.
