guanosine 5'-diphosphate sodium

Guanosine 5'-diphosphate (GDP) sodium 是一种核苷二磷酸，可激活 5'-三磷酸腺苷敏感的 K+通道。Guanosine 5'-diphosphate sodium 是一种潜在的铁动员剂，可阻断铁调素-铁转运蛋白 (hepcidin-ferroportin) 相互作用并调节 IL-6 stat-3通路。Guanosine 5'-diphosphate sodium 可用于炎症研究，如炎症性贫血 (AI)。

Guanosine 5’-diphosphate (GDP) is a purine nucleotide and biosynthetic precursor of guanosine 5’-triphosphate .1It has been used to study the conformations of GTPases.2GDP (100 μM) activates sulfonylurea receptor 2B (SUR2B) linked to the inward-rectifier potassium channel 6.1 (Kir6.1) in HEK293T cells in a patch-clamp assay.3 1.Berg, J.M., Tymoczko, J.L., and Stryer, L.Biochemistry(2002) 2.Vetter, I.R., and Wittinghofer, A.The guanine nucleotide-binding switch in three dimensionsScience294(5545)1299-1304(2001) 3.Yamada, M., Isomoto, S., Matsumoto, S., et al.Sulphonylurea receptor 2B and Kir6.1 form a sulphonylurea-sensitive but ATP-insensitive K+ channelJ.
