KMUP-1 is a xanthine derivative with vasodilator activity. KMUP-1 is a inhibitor of phosphodiesterase (PDE) and activator of soluble guanylyl cyclase (sGC). KMUP-1 stimulates NO/sGC/cyclic GMP pathway. KMUP-1 has K+ channels opening activity. KMUP-1 ameliorates ischemia-induced cardiomyocyte apoptosis. KMUP-1 can be used for cardiovascular and anti-inflammatory study[1][2].
