Exendin-3 (9-39) amide is a truncated form of the exendin-4 (48-86) amide peptide that acts as a potent competitive antagonist for the glucagon-like peptide 1 receptor (GLP-1R; Kd = 1.7 nM in CHL cells transfected with cloned human GLP-1).[1] It inhibits exendin-3-induced increases in cAMP levels in guinea pig pancreas cells (IC50 = 20 nM).[2] Exendin-3 (9-39) amide administration in the hypothalamus (10 and 100 µg, i.c.v.) reverses GLP-1 inhibition of feeding behavior in rats.[3]

DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
