Two congeneric peptides that inhibit contraction of the anterior byssus retractor muscle of Mytilus edulis were isolated from the pedal ganglia of the mussel. Their structures were determined to be H-Gly-Ser-Pro-Met-Phe-Val-NH2 and H-Gly-Ala-Pro-Met-Phe-Val-NH2. These hexapeptides also showed inhibitory action on contractions in several other molluscan muscles, such as the cardiac muscle of Meretrix lusoria and the penis retractor muscle of Achatina fulica.
从贻贝的足神经节中分离出两种抑制紫贻贝前足丝牵缩肌收缩的同属肽。它们的结构被确定为H-Gly-Ser-Pro-Met-Phe-Val-NH2和H-Gly-Ala-Pro-Met-Phe-Val-NH2。这些六肽对其他几种软体动物肌肉的收缩也有抑制作用，如中国蛤蜊的心肌和非洲大蜗牛的阴茎牵缩肌。
