Nitric oxide (NO) protects from blood vessel spasms and clot formation. Conversely, insufficient NO occurs in cardiovascular disease. Life-saving drugs like glycerol trinitrate supply more NO to blood vessels, however these drugs are limited in their action when their target protein (NOGC) is decreased or defective, eg. in hypertension or arteriosclerosis. We have elucidated the reason for this defect and simultaneously discovered an entirely novel group of drugs which activate NOGC without NO. Impressively, these drugs are most effective in diseased blood vessels. The aim is the development of novel blood pressure lowering/anti-anginal drugs with higher effectiveness and less side-effects because they work in an entirely new way.
