抄録

A highly polymethylated flavone that effectively inhibited cytochrome P450s (CYPs) 1A2 and 3A4 (IC₅₀=2.41 and 1.71 μM) in vitro was isolated from thyme leaves (Thymus saturoides) purchased from a Japanese market. Its structure was spectroscopically identified as 4′,5-dihydroxy-3′,6,7,8-tetramethoxy flavone (8-methoxycirsilineol, 1). This is the first report describing a strong inhibitor of CYP1A2 and 3A4 isolated from Thymus saturoides.
