Cat.No. 4657 - Zolmitriptan | C16H21N3O2 | CAS No. 139264-17-8
Description: Potent 5-HT1B/1D/1F agonist
Chemical Name: (4S)-4-((3-(2-(Dimethylamino)ethyl)-1H-indol-5-yl)methyl)-2-oxazolidinone
Purity: ≥99% (HPLC)

Biological Activity

Potent 5-HT1B/1D/1F agonist (Ki values are 0.63, 5.01 and 63.09 nM for h5-HT1D, h5-HT1B and h5-HT1F receptors respectively). Inhibits trigeminal nerve stimulation-mediated neurogenic plasma protein extravasation in guinea pigs; blocks long excitatory postsynaptic potentials (EPSPs) in a rat model of spinal cord injury.
