Phe-Met-Arg-Phe, amide 产品活性：Phe-Met-Arg-Phe, amide 是一种神经肽，在肽能神经元中激活 K+电流，ED50 为23 nM，这种作用具有剂量依赖性。 产品来源： https://www.medchemexpress.cn/Phe-Met-Arg-Phe,_amide.html 研究领域：Membrane Transporter/Ion Channel 作用靶点：Potassium Channel In Vitro: In the molluscan central nervous system, Phe-Met-Arg-Phe, amide (FMRFa) acts on K+ channels in sensory, motor-, and neuroendocrine neurones. Phe-Met-Arg-Phe, amide activates a novel K+ current that is characterized by a combined voltage- and receptor-dependent gating mechanism, with both factors being necessary for opening of the channels. Phe-Met-Arg-Phe, amide (1 μM) significantly inhibits glucose stimulated (300 mg/dL) insulin release (p<0.005) and somatostatin release (p<0.01) from the isolated perfused pancreas. Phe-Met-Arg-Phe, amide (FMRF-NH2) (1 and 10 μM) is without effect on glucagon secretion, either in low glucose (50 mg/dL), high glucose (300 mg/dL), or during arginine stimulation (5 mM). In Vivo: Phe-Met-Arg-Phe, amide (FMRFamide) stimulates growth hormone secretion in conscious OVX rats. The presence of Phe-Met-Arg-Phe, amide-like immunoreactivity in neuronal elements in the hypothalamus suggested a role for this in the hypothalamic control of the anterior pituitary function. The injection of 200 ng (313.8 picomoles) of FMRFamide (in 2 uL) produces a significantly increased plasma GH 15 min after injection. The GH-increasing effect of 400-800 ng (627-1255 picomoles) of FMRFamide is already developed after 5 min and lasted up to 30 min. 相关产品：Nigericin sodium salt | Yoda 1 | BAPTA-AM | Minocycline hydrochloride | Branaplam | Rosuvastatin Calcium | SCH-23390 hydrochloride | Glibenclamide | Quinidine (15% dihydroquinidine) | Carbamazepine | Tetrandrine | E-4031 | DCPIB | Minoxidil | Amiodarone hydrochloride | 20(S)-Ginsenoside Rg3 | Guanosine 5'-diphosphate disodium salt | Tannic acid | Quinine | TRAM-34 | SKF-96365 hydrochloride | (±)-Naringenin | Astemizole | PAP-1 | Terfenadine | Flufenamic acid | Ifenprodil tartrate | 4-Aminopyridine | Mefloquine hydrochloride | GW9508 品牌介绍: MCE (MedChemExpress) 拥有数百种全球独家化合物，我们致力于为全球科研客户提供最新最全的高品质小分子活性化合物；10,000 多种高选择性抑制剂、激动剂涉及各热门信号通路及疾病领域；设有专业的实验中心和严格的质控、验证体系；提供 LC/MS、NMR、HPLC、手性分析、元素分析等各项质检报告，确保产品的高纯度、高品质；产品的生物活性多经各国客户实验验证；Nature, Cell, Science 等多种顶级期刊及制药专利收录了MCE客户的科研成果；专业团队跟踪最新的制药及生命科学研究进展，为您提供全球最新的活性化合物；与世界各大制药公司及知名科研机构建立了长期的合作。
