CYM2503 是 GAL2 受体的正变构调节剂 (PAM),可在体外增强甘丙肽诱导的 IP1 产生。它对受体的正构甘丙肽结合位点没有亲和力(通过其无法置换碘化甘丙肽或自行诱导 IP1 积累来衡量)。
产品描述
CYM2503 is a positive allosteric modulator (PAM) of the GAL2 receptor that potentiates galanin-induced IP1 production in vitro. It has no affinity for the orthosteric galanin binding site of the receptor (as measured by its inability to displace iodinated galanin, or to induce IP1 accumulation on its own).
体外活性
CYM2503 potentiated the galanin-stimulated IP1 accumulation in HEK293 cells stably expressing GalR2 receptor, whereas it exhibited no detectable affinity for the (125)I galanin-binding site of GalR2 receptor, an effect consistent with that of a positive allosteric modulator.
体内活性
In the rat Li-pilocarpine status epilepticus model, CYM2503, injected intraperitoneally, increased the latency to first electrographic seizure and the latency to first stage 3 behavioral seizure, decreased the latency to the establishment of status epilepticus, and dramatically decreased the mortality.?In a Li-pilocarpine seizure model in mice, CYM2503 increased the latency to first electrographic seizure and decreased the total time in seizure.?CYM2503 also attenuated electroshock-induced seizures in mice.?Thus, CYM2503 provides a starting point for the development of anticonvulsant therapy using the galanin R2 receptor as target.
