TMS

TMS ((E) -2,3',4,5'-tetramethoxystilbene) is a selective and competitive CYP1B1 inhibitor with an IC50 of 6 nM and a Ki value of 3 nM. TMS shows a lesser extent inhibitory effect on CYP1A1 (IC50=300 nM) and CYP1A2 (IC50=3.1 μM) . TMS is a methylated derivative of resveratrol and has anti-cancer activity[1][2][3].
