The first total synthesis of (−)-6-O-desmethylantofine (A) and its unnatural enantiomer (+)-6-O-desmethylantofine (B) is described. The synthetic route is efficient and practical with easily available glutamic acid dimethyl ester hydrochloride as the chiral material under mild conditions.
Compound R-12, the cyanomethyl ether of 6-desmethylantofine, exhibited significant anti-cancer activity and inhibited the proliferation of a panel of 30 cancer cell lines including 2 multi-drug-resistant cell lines with an average IC50 value of 18.7 nM, which suggests that R-12 is a promising new anti-cancer agent. Our studies suggest that R-12 displayed potent inhibitory effect on cell growth and colony
