产品描述 | Donitriptan hydrochloride is a potent, selective, high-efficacy agonist at 5-HT1B/1D receptors both in vivo and in vitro in neuronal and vascular models relevant to migraine. Donitriptan hydrochloride has subnanomolar affinity for cloned human and nonhuman 5-HT1B and 5-HT1D receptors with Ki values ranging from 0.1-4.3 nM. It potently inhibits forskolin-induced cAMP accumulation mediated by recombinant human and nonhuman, stably transfected 5-HT1B and 5-HT1D receptors with mean EC50 values ranging from 0.2-1.9 nM [1]. In mammals, 5-hydroxytryptamine (5-HT) is important in regulating emotions and related behaviors as a neurotransmitter [2]. In C6 glioma cells transfected with human 5-HT1B or 5-HT1D receptors, donitriptan hydrochloride enhanced specific GTPγ35S binding at both 5-HT1B and 5-HT1D receptors to a greater extent, compared with rizatriptan, naratriptan, sumatriptan, dihydroergotamine and zolmitriptan, but to a level equivalent to which evoked by 5-HT. In guinea pig-isolated trigeminal ganglion neurons, treatment with donitriptan hydrochloride resulted in increase in Ca2+-dependent K+ current (pD2 = 7.3) [1]. Oral administration with donitriptan hydrochloride in guinea pigs resulted in hypothermic responses with an ED50 of 1.6 mg/kg. Compared with zolmitriptan, naratriptan and rizatriptan with an ED50 of 8.3, 9.9 and 12.3 mg/kg, respectively, donitriptan hydrochloride showed superior potency. There is likelihood that donitriptan hydrochloride gains access to the brain [1].Donitriptan hydrochloride is orally active and well tolerated by animals, displays unique craniovascular selectivity and a long duration of action, and gains access to the brain.
