Proadrenomedullin N-terminal 12 peptide (PAMP-12) 是一种内源性肽段,源自人体肾上腺髓质,对应人类PAMP-20的9-20氨基酸,涉及降低血压。它是MAS相关G蛋白偶联受体家族成员X2 (MRGPRX2) 的激动剂。在表达人MRGPRX2的CHO细胞中,PAMP-12抑制forskolin诱导的cAMP积累(EC50 = 57.2 nM),特异性诱导表达MRGPRX2的CHO细胞的钙离子动员(EC50 = 41 nM),而在表达MRGPRX1、MRGPRX3或MRGPRX4的细胞中则无此效应(在1 µM浓度下)。PAMP-12还能作为烟碱型乙酰胆碱受体(nAChRs)的拮抗剂,抑制carbachol诱导的儿茶酚胺释放(IC50 = 1.3 µM)及钙和钠的流入(IC50分别为0.39 µM和0.87 µM),但不抑制组胺诱导的儿茶酚胺释放或钙和钠的流入(IC50 <1 µM),在初级牛肾上腺嗜铬细胞中有此表现。当以10至50 nmol/kg剂量给予正常血压大鼠时,PAMP-12能降低平均动脉血压。

产品描述 | Proadrenomedullin N-terminal 12 peptide (PAMP-12), an endogenous fragment originating from the adrenal medulla and spanning amino acids 9-20 of human PAMP-20, plays a role in causing hypotension. It functions as an agonist for the MAS-related G protein-coupled receptor family member X2 (MRGPRX2), inhibiting forskolin-stimulated cAMP accumulation in CHO cells expressing human MRGPRX2 (EC50 = 57.2 nM) and selectively prompting calcium mobilization in these cells (EC50 = 41 nM), but not in cells expressing MRGPRX1, MRGPRX3, or MRGPRX4 at 1 µM. As an antagonist of nicotinic acetylcholine receptors (nAChRs), PAMP-12 obstructs carbachol-triggered catecholamine release and the influx of calcium and sodium (IC50s = 1.3, 0.39, and 0.87 µM, respectively) in primary bovine adrenal chromaffin cells, with no effect on histamine-induced responses (IC50s = >1 µM for all). Additionally, it decreases mean arterial blood pressure in normotensive rats at doses ranging from 10 to 50 nmol/kg. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
