S-Nitrosoglutathione (GSNO) is an amino acid nitric oxide donor, when under physiological conditions spontaneously releases nitric oxide. In research, S-Nitrosoglutathione (GSNO) has been observed to selectively inhibit platelet activation and display cardioprotective effects. S-Nitrosoglutathione (GSNO) also inhibits NF-kappaB activation, endothelial cell proliferation and cathepsin B (cysteine proteases). GNSO has demonstrated dose dependent effects on Thymocytes by inducing apoptosis in T cells in low concentrations (< 0.6 mM), while protecting T cells from apoptosis in higher concentrations (1-2 mM).

Rated 5 out of 5 by from EricksonErickson, JR. et al. (PubMed 26316536) found parallel effects of GSNO, a NO donor, on CaM/CaMKII binding and CaMKII -dependent ryanodine receptor activation in adult cardiac myocytes. They concluded that NO can play a dual role in regulating cardiac CaMKII activity. -SCBT Publication Review
