Rotigaptide (ZP123) 是连接蛋白 43 (Cx43) 的特异性调节剂。Rotigaptide 可防止 Cx43 介导的间隙连接 (gap junction) 通讯的解偶联，并在急性代谢应激期间使细胞间通讯正常化。Rotigaptide 是一种抗心律失常肽 (AAP)，有潜力用于心律失常-特别是房颤的相关研究。
Rotigaptide (ZP123) is a novel and specific modulator of connexin 43 (Cx43). Rotigaptide prevents the uncoupling of Cx43-mediated gap junction communication and normalizes cell-to-cell communication during acute metabolic stress. Rotigaptide is a potent antiarrhythmic peptide (AAP) with improved stability and has the potential for the investigation of cardiac arrhythmias-specifically atrial fibrillation[1][2].
