title: E-Combretastatin and E-resveratrol structural modifications: antimicrobial and cancer cell growth inhibitory beta-E-nitrostyrenes.
abstract: As part of a broad-based SAR investigation of E-resveratrol (strong sirtuin activator and antineoplastic) and the anticancer vascular-targeting combretastatin-type stilbenes, a series of twenty-three beta-E-nitrostyrenes was synthesized in order to evaluate potential antineoplastic, antitubulin, and antimicrobial activities. The beta-E-nitrostyrenes evaluated ranged from monosubstituted phenols to trimethoxy and 3-methoxy-4,5-methylenedioxy derivatives. Two of the beta-nitrostyrenes were synthesized as water-soluble sodium phosphate derivatives (4t, 4v). All except four (4r, 4s, 4t, 4u) of the series significantly inhibited a minipanel of human cancer cell lines. All but eight led to an IC(50) of <10 microM for inhibition of tubulin polymerization, and all except three (4l, 4t, 4v) displayed antimicrobial activity.
