Neuropeptide Y (NPY) (13-36) is a C-terminal fragment of NPY, a neuropeptide involved in controlling appetite, blood pressure, cardiac contractility, and intestinal secretion. NPY (13-36) is an agonist of the NPY receptor Y2 with Ki values of 1.28 and 2.62 nM for the rat recombinant receptor in CHO cells and in rat jejunal crypt cell membranes, respectively. It inhibits forskolin-induced cAMP accumulation with EC50 values of 300, 2.2, >1,000, and 20 at Y1, Y2, Y4, and Y5 receptors, respectively, in vitro. NPY (13-36) inhibits basal short circuit currents (EC50 = ~2 µM) and electrical field stimulated-secretory responses in isolated rat jejunal mucosa (EC50 = ~200 nM) but does so less potently than NPY . NPY (13-36) also reduces the frequency of spontaneous excitatory postsynaptic currents (EPSCs) in the CA3 region of hippocampal slices from wild-type but not Y5 receptor knockout mice.

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。
