Guanylyl Imidodiphosphate

Guanylyl Imidodiphosphate (Guanosine 5'-[β,γ-imido]triphosphate) trisodium 是一种不可水解的 GTP 类似物，是ADP-核糖基化因子 (ARF) 激活剂和腺苷酸环化酶 (adenylate cyclase) 的有效刺激物。Guanylyl Imidodiphosphate trisodium 可用于蛋白质合成研究。

Guanylyl Imidodiphosphate (lithium salt) 是一种 GTP 类似物，不可水解，可增加腺苷酸环化酶 (adenylate cyclase) 活性。

Neuromedin C is a bombesin-like neuropeptide that stimulates uterine smooth muscle contraction and the release of gastrin , somatostatin, and amylase in rats. Neuromedin C is a truncated form of gastrin-releasing peptide corresponding to the GRP amino acids 18-27. It inhibits GRP and bombesin binding to rat pancreatic membranes (IC50s = 0.4 and 2.2 nM, respectively), which can be reduced by sodium chloride and guanylyl imidodiphosphate . Neuromedin C induces scratching and mast cell degranulation in mice when administered intradermally at doses ranging from 1 to 300 nmol/site, which is inhibited by the BB2 bombesin receptor agonist RC-3095 and reduced in mast cell-deficient mice. Neuromedin C (3.2 nmol/kg, i.p.) reduces rat glucose consumption by approximately 50% for up to one hour.
