Chromogranin A (324-337), human 是嗜铬粒蛋白 A 的一个肽片段，可从人的回肠类癌肿瘤中分离出来。嗜铬粒蛋白 A 是一种可溶性糖蛋白，与激素和神经肽一起储存在大多数（神经）内分泌细胞和神经元的分泌颗粒中，它也是神经内分泌肿瘤的血浆标志物。

Yadanzigan (YDZG) is an anti-inflammatory agent and a NLRP3 inhibitor. Yadanzigan specifically inhibits NLRP3 activation via inhibiting NF-κB pathway and Reactive Oxygen Species production. Yadanzigan also moderates LPS -induced acute lung injury (ALI) in mice.

Endogenous peptide agonist of Mas related GPR X2 (MRGPRX2, EC50 = 251 nM). Also a noncompetitive nicotinic cholinergic antagonist. Inhibits nicotine-stimulated catecholamine secretion from PC12 cells in vitro, and from sympathetic nerve endings and adrenal chromaffin cells in vivo. Corresponds to amino acids 1 - 20 of proadrenomedullin. Antihypertensive.
