NONOate

The structure of a typical NONOate group

In

nitrosyl group. In contact with water, these compounds release NO (nitric oxide).[1][2]

pH-dependent decomposition of NONOates

Most NONOates are stable in

half-lives (t½) in phosphate buffer at pH 7.4. For example, the half-life of MAHMA NONOate under these conditions is ~3.5 minutes, whilst the t½ of DPTA NONOate is 300 minutes. This is often useful in biological systems, where a combination of different NONOates can be used to give a sustained release of nitric oxide. At pH 5.0, most NONOates are considered to decompose
almost instantaneously.
