Human microsomal cytochrome P450 (CYP) 2A6 contributes extensively to nicotine detoxication but also activates tobacco-specific procarcinogens to mutagenic products. We prepared a series of benzofuran and coumarin derivatives that have inhibitory effects on the activity of human CYP2A6. The reported compounds methoxalen and menthofuran had potent inhibitory effects on the activity of CYP2A6 with IC50 values of 0.47 µM and 1.27 µM, respectively. Synthetic benzofuran (4-methoxybenzofuran: IC50=2.20 µM) and coumarin (5-methoxycoumarin: IC50=0.13 µM and 6-methoxycoumarin: IC50=0.64 µM) derivatives, which have more selective effects than those of methoxalen and menthofuran, exhibited comparable activities against CYP2A6. These compounds can be used as a lead compounds in the design of CYP2A6 inhibitor drugs to reduce smoking and tobacco-related cancers.

A possible biomimetic connection between atractylolide, hydroxyatractylolide and biatractylolide and biepiasterolide has been demonstrated by efficiently generating the biatractylolide and biepiasterolide core structures from atractylolide and hydroxyatractylolide model butenolides via a radicaloid intermediate in a single step in good yield.
