چکیده انگلیسی
New resveratrol (RES) analogs were developed by replacing the aromatic 'core' of our initial naphthalene-based RES analogs with pseudo-heterocyclic (salicylaldoxime) or heterocyclic (benzofuran, quinoline, and benzothiazole) scaffolds. The resulting analogs were tested for their antiproliferative and vasorelaxing effect, two typical properties shown by RES. Some of the new compounds confirmed strong antiproliferative activities, comparable to that previously found with the most active naphthalene-based analog. In particular, 3-(3,5-dihydroxyphenyl)-7-hydroxyquinoline exhibited the most potent antiproliferative effect (IC50 = 17.4 μM). In vascular assays, the highest levels of potency (pIC50 = 4.92) and efficacy (Emax = 88.2%) were obtained with 2-(3,5-dihydroxyphenyl)-6-hydroxybenzothiazole. A conformational analysis of these compounds indicated that the antiproliferative activity on MDA-MB-231 cancer cells can be correlated to a common sterical profile of the most active compounds and, in particular, to the spatial arrangement of the three phenolic groups. Furthermore, the vasorelaxing properties showed a good correlation with the electronic properties measured through the electrostatic molecular potential (ESP).
