Cytotoxicity of furoxans: quantitative structure-activity relationships study.
Furoxans are interesting biological active compounds. Recent studies demonstrate that they are cytotoxic under aerobic conditions. This paper shows that this cytotoxicity could be related with E(LUMO), calculated LogP and Mulliken charge on heterocycle nitrogen 2 calculated at ab initio level (3-21G* basis). It was possible to propose a tentative mechanism of cytotoxicity and structural modifications to modulate the cytotoxic potency of furoxan derivatives.
