Description

technical field [0001] The present invention relates to the field of pharmacy and medicinal chemistry, and relates to a NO-donating statin derivative, a preparation method and application thereof, in particular to an N-aryl-N'-hydroxyguanidine NO-donating statin derivative and a preparation method thereof and application. Background technique [0002] Nitric oxide (Nitric oxide, NO) is an important gaseous small molecule that was discovered in mammals in the 1980s to perform the messenger function. In 1992, it was selected as the star molecule of the year by the American Science magazine. Since the late 1980s, people have mainly studied the physiological function of N0. It is found that it can relax blood vessels and participate in blood pressure regulation; it can reduce the aggregation of platelets and has antithrombotic function; it can also inhibit the proliferation of vascular smooth muscle and have anti-atherosclerotic effects; it can affect the release of neurotransm...
