quantitative structure-activity relationship (3D-QSAR)/comparative molecular similarity indices analysis (CoMSIA) methods have been successfully applied to explain the cytotoxicactivity of a set of 51 natural and synthesized naphthoquinone derivatives tested in human promyelocytic leukemia HL-60 cell line. The computational models have facilitated the identification of structural elements of the ligands

Sixteen derivatives (2-17) synthesized from the naphthoquinone lapachol (1), were tested for their inhibitory effects on Epstein-Barr virus early antigen (EBV-EA) activation induced by 12-O-tetradecanoylphorbol-13-acetate (TPA), as a test for potential cancer chemopreventive agents. They exhibited a variety of inhibitory activities from very high to moderate, which allow us to suggest structure-activity relationships. Ten of these derivatives are reported for the first time, their structures being thoroughly determined by spectroscopic methods. (C) 2002 Elsevier Science Ltd. All rights reserved.
Growth inhibitory activity for cancer cell lines of lapachol and its natural and semi-synthetic derivatives
A series of 17 selected natural and semisynthetic 1,4-naphthoquinones were synthesized, and their growth inhibitory activity was evaluated in vitro. The compounds were tested on six human cancer cell lines using the MTT colorimetric assay. The data revealed that of the chemicals under study only lapachol, its acetate and 3-geranyllawsone displayed the highest activity, recording mean IC50 values ranging from 15 to 22 mu M.
