QUICK LINKS

Selective activator of cGMP-dependent protein kinase (PKG) Iα, Iβ, and type II as well as of cGMP-gated ion channels. Higher activation potential as compared to cGMP; excellent cell membrane permeability and phosphodiesterase stability. Preferred alternative to unsuitable analogs such as dibutyryl-cGMP.
