Nitric oxide (NO) is a unique biochemical mediator involved in the regulation of vital processes. Its short lifetime in physiological conditions and local action impede direct application in medicine because highly targeted NO-delivery systems are required. Light-controllable NO releasers are promising for the development of smart therapies. Here we present simply prepared meso-aminomethyl BODIPY derivatives containing N-nitroso moiety, which show the photoinduced generation of NO in a solution. These compounds can additionally generate singlet oxygen, and NO/1O2 generation efficiency can be tuned by substituents. As an example of NO-mediated effect, we demonstrate light-dependent inhibition of platelet activation in vitro. The presented compounds could serve as the basis for the development of novel hybrid therapeutic methods.
