GS 389 is a novel tetrahydroisoquinoline analog with vasorelaxant properties. GS-389 significantly inhibited cGMP phosphodiesterase from the rabbit brain and increased cGMP levels in the rat aorta.
CB096 is a novel inhibitor of RAN translation. specifically binds to a repeating 1 × 1 GG internal loop structure, 5'CGG/3'GGC, that is formed when r(G4C2)exp folds, also acting as a potent vasorelaxant agent, showing antihypertensive effect.
ent-3-Acetoxy-labda-8(17),13-dien-15-oic acid have vasorelaxant and hypotensive actions, the mechanisms underlying the cardiovascular actions of the labdane involve the activation of the endothelial NO-cGMP pathway, the opening of K+ channels and the alteration on Ca2+ mobilization.
