NAS-181 dimesylate
Based on 3 publication(s) in Google Scholar
NAS181 is a potent and selective antagonist of rat 5-HT1B receptor, with a Ki of 47 nM. NAS181 shows 13-fold selectivity for r5-HT1B over bovine 5-HT1B receptor (Ki=630 nM). NAS181 increases the 5-HT turnover and the synaptic concentration of 5-HT by inhibiting terminal r5-HT1B autoreceptors.

Rat 5-HT1B Receptor 47 nM (IC50) |
NAS181 has very low affinities (Ki>3000 nM) for all other receptors examined, including 5-HT2A, 5-HT2C, 5-HT6, and 5-HT7, α1-, α2-, and β-adrenoceptors, and dopamine D1 and D2[1].
NAS181 (10-1000 nM) dose-dependently potentiates the K+-stimulated [3H]-5-HT release in preloaded rat occipital cortical slices[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
NAS181 (20 mg/kg; s.c.) enhances the 5-HT turnover in four rat brain regions (hypothalamus, hippocampus, striatum, and frontal cortex) with about 40%[1].
NAS181 (3 mg/kg; s.c.) produces a significant increase in the number of wet dog shakes in rats[1].

Animal Model:Adult male Sprague-Dawley rats (250-300 g)
-
Dosage:1, 5, 10 mg/kg
-
Administration:S.c. in the scruff of the neck
-
Result:Increased the ACh release in the frontal cortex, reaching the maximal value of 500% of the control group within 80 min after the injection of the highest dose.
Increased the ACh releases in VHipp with a maximum of 230% of the control values at 80 min after the injection of the highest dose.
