Description

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.

IC 50

Tachykinin NK₂ Receptor: 7.9 (pA2); NK1: 5.2 (pA2); NK3: 4.9 (pA2)
