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.

Metabolic reprogramming of tumor cells involves upregulation of fatty acid (FA) synthesis to support high bioenergetic demands and membrane synthesis. This has been shown for cytosolic synthesis of FAs with up to 16 carbon atoms. Synthesis of long-chain fatty acids
