Abstract

© 2016 American Chemical Society. Nitric oxide (NO) has been heavily studied over the past two decades due to its multitude of physiological functions and its potential therapeutic promise. Of major interest is the desire to fabricate or coat implanted devices with an NO releasing material that will impart the appropriate dose and duration of NO release to positively mediate the biological response to the medical device, thereby improving its safety and efficacy. To date, this goal has not yet been achieved, despite very promising early research. Herein, we describe the synthesis and NO release properties of a novel NO donor which covalently links the S-nitrosothiol, S-nitroso-N-acetyl-D-penicillamine (SNAP), to the macrocycle, cyclam (SNAP-cyclam). This compound can then be blended into a wide variety of polymer matrices, imparting NO release to the polymer system. This release can be initiated and controlled by transition metal catalysis, thermal degradation or photolytic release of NO from the composite NO-releasing material. SNAP-cyclam is capable of releasing physiologically relevant levels of NO for up to 3 months in vitro when blended into poly(l-lactic acid) thin films.
