This work describes the synthesis of some benzoic (1-4) and alcoholic (5-7) nitrooxy derivatives, which are nitric oxide (NO) donors in themselves, and can also be seen as useful linkers that can be used in multi-target drugs capable of releasing NO. The NO-mediated vasorelaxing effects of the compounds were tested on endothelium-denuded isolated rat aortic rings pre-contracted with KCl. The pharmacological study of these compounds demonstrated that slight structural modification, such as the insertion of (a) methyl group(s) into the nitrooxymethyl chain or into the aromatic ring, and a change in the position of this nitrooxymethyl chain, could exert a marked (and potentially useful) influence on the NO releasing properties.

Abstract
This work describes the synthesis of some benzoic (1-4) and alcoholic (5-7) nitrooxy derivatives, which are nitric oxide (NO) donors in themselves, and can also be seen as useful linkers that can be used in multi-target drugs capable of releasing NO. The NO-mediated vasorelaxing effects of the compounds were tested on endothelium-denuded isolated rat aortic rings pre-contracted with KCl. The pharmacological study of these compounds demonstrated that slight structural modification, such as the insertion of (a) methyl group(s) into the nitrooxymethyl chain or into the aromatic ring, and a change in the position of this nitrooxymethyl chain, could exert a marked (and potentially useful) influence on the NO releasing properties.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
