Peptide blockers of PKG inhibit ROS generation by acetylcholine and bradykinin in cardiomyocytes but fail to block protection in the whole heart.

Thomas Krieg et al.

American journal of physiology. Heart and circulatory physiology, 288(4), H1976-H1981 (2004-12-14)

Bradykinin and acetylcholine (ACh) trigger preconditioning by ATP-sensitive K(+) (K(ATP)) channel-dependent production of reactive oxygen species (ROS). Recent evidence suggests that ROS production may in turn be influenced by cGMP-dependent protein kinase (PKG). This study utilized DT-2 and DT-3 peptides

Exploring the mechanisms of vascular smooth muscle tone with highly specific, membrane-permeable inhibitors of cyclic GMP-dependent protein kinase Ialpha.

Wolfgang R G Dostmann et al.

Pharmacology & therapeutics, 93(2-3), 203-215 (2002-08-23)

The structural similarity of cyclic GMP-dependent protein kinase (cGPK) and cyclic AMP-dependent protein kinase (cAPK) has made it difficult to study cGPK pathways independent of those mediated by cAPK, primarily due to the lack of potent and selective cGPK inhibitors.

Highly specific, membrane-permeant peptide blockers of cGMP-dependent protein kinase Ia inhibit NO-induced cerebral dilation
