General description

A metabolically-stable, competitive inhibitor of protein kinase G type Iα and Iβ (Ki = 30 nM) that also blocks cGMP-gated retinal type ion channels (IC50 = 25 µM). Also reported to block the activation of purified PKA type II (Ki = 10 µM). More lipophilic and cell-permeable than Rp-8-pCPT-cGMPS (Cat. No. 370677). Note: 5 µmol = 2.81 mg.
