title: Controlled release of HNO from chemical donors for biological applications.
abstract: Nitroxyl (HNO) is a small molecule with various pharmacological effects, including cardioprotective action. It is thought to serve as a modulator of various biochemical pathways. But, it is difficult to apply HNO directly for biological experiments or therapeutic treatment because it is highly reactive, readily dimerizing or reacting with biological targets under ambient conditions. Therefore, HNO donor molecules that release HNO under physiological conditions, especially those that allow precisely controllable release, would be useful to study the activities of HNO at the cellular level. This short review focuses on recently developed photocontrollable HNO-releasing compounds, which are expected to be suitable for achieving site-specific and temporally controlled HNO release in biomedical investigations. An illustrative application for the study of HNO-mediated upregulation of calcitonin gene-related peptide (CGRP) in A549 cells is described.
