Rotigaptide

Chemical compound

Rotigaptide (ZP-123) is a drug under clinical investigation for the treatment of cardiac arrhythmias – specifically atrial fibrillation. It is a peptide analog that has been shown to increase gap junction intercellular conductance in cardiac muscle cells. Gap junctions are protein channels that are responsible for conducting electrical impulses between cells in the heart to maintain normal rhythm. Gap junction modulation is a promising and novel mechanism of action for the treatment of cardiovascular disorders. Its peptide sequence is Ac-D-Tyr-D-Pro-D-Hyp-Gly-D-Ala-Gly-NH2.
