Currently, polytherapies based on the combined utilization of reverse transcriptase and HIV protease inhibitors are the most efficient in AIDS treatment. Clinical assays clearly established the efficacy of these therapies in reducing the viral load below to its detection threshold. They also showed the therapy efficacy in recovering T CD4 cell count. However, the existence of virus reservoirs at the lymphatic system and at the central nervous system indicates that reverse transcriptase and protease inhibitors are not completely efficient. In the treatment of hypertension the renin-angiotensin-aldosterone (RAAS) plays a major role in regulating blood pressure. Inhibition of renin protease activity is a potential therapeutic strategy in the treatment of hypertension. Common structural and functional features between HIV-protease and Renin lead us to propose the design of inhibitors with double action.This research proposal involves theoretical calculations, synthesis of aryl-amides, aryl-pirimidinones, and their s-nitrosothiol derivatives. The compounds will be synthesized using environmentally sustainable techniques. Reactions will be carried out under microwave irradiation in solvent-free conditions and/or organic carbonates as solvents. NMR and IR-based analysis will be used to determine the compounds stability in addition to other physicochemical parameters. The synthesized and chemically characterized compounds will be tested as HIV-protease and Renin protease inhibitors. (AU)
