MEN 10207 is a tachykinin antagonist. | [Uses]
MEN 10207 is a selective NK-2 tachykinin receptor (Neurokinin Receptor) antagonist. MEN 10207 has pA2 values of 5.2, 7.9 and 4.9 in three monoreceptor in vitro assays for NK-1, NK-2 and NK-3 tachykinin receptors, respectively. | [in vivo]
but not Substance P in a dose-dependent manner. And MEN 10207 also effectively blocks the long-term reflex facilitation to the gastrocnemius nerve stimulation[1]. | Animal Model: | Decerebrate, spinalized, unanesthetized Female Sprague-Dawley rats (250-280 g)[1] | | Dosage: |
7 pmol/10 μL, 70 pmol/10 μL, 700 pmol/10 μL | | Administration: | Intrathecal administration; once | | Result: | Blocked the reflex facilitation to intrathecal Neurokinin A, but not Substance P in a dose-dependent manner. |
