anti-hormonal therapy, the development of new antineoplastic drugs is necessary. Lawsone (2-hydroxy-1,4-naphtoquinone) is a natural bioactive naphtoquinone displaying a range of activities, with dozens of derivatives described in the literature, including some glycosides possessing antitumor activity. Here, a series of glycosides of lawsone are reported for the first time and all compounds displayed good activity
Compounds with cancer cell specific lethality are provided. In particular, RAS-selective lethal compounds and compositions are provided. Also provided are methods of screening for such compounds and methods of treating a condition in a mammal, by administering to the mammal a therapeutically effective amount of such compounds or compositions.

A method is proposed for the synthesis of acetylated glycosides of hydroxynaphthoquinones. The condensation of D-glucose and D-galactose (tert-butyl orthoacetate)s with lawsone and lapachol has given the tetra-O-acetyl-β-D-glucopyranosides of lawsone and of lapachol and the tetra-O-acetyl-β-galactopyranoside of lawsone. The structures of the glycosides obtained have been confirmed by IR and1H and13C
