Naratriptan
Based on 2 publication(s) in Google Scholar
Naratriptan is an orally active and selective 5-HT1B/1D receptor agonist. Naratriptan is peripherally active and has good oral bioavailability, inducing cranial artery vasoconstriction by activating 5-HT1B/1D receptors (EC50=0.11 μM for dog basilar artery). Naratriptan also inhibits trigeminal nerve-mediated dural neurogenic plasma extravasation and reduces sterile inflammation. Naratriptan is mainly used in the research of acute migraine, targeting cranial vascular and neuroinflammatory mechanisms.

5-HT1 Receptor |
Naratriptan targets human recombinant 5-HT1B and 5-HT1D receptors with Ki of 0.47 nM and 0.69 nM, and EC50 of 4.4 nM and 23 nM, respectively; while for 5-HT1A, Ki=26 nM, EC50=79 nM[1].
Naratriptan targets 5-HT1B, 5-HT1D, and 5-HT1F with pKi of 8.7, 8.3, and 8.1, respectively[2].
Naratriptan can inhibit the discharge response of cat-derived nucleus tractus solitarius (NTS) cells that regulate vomiting by 54%; this activity suggests that Naratriptan has inhibitory activity on NTS in trigeminal nerve vessels and can be used in the study of migraine inhibition[2].
Naratriptan induces concentration-dependent contraction in isolated dog basilar artery and middle cerebral artery experiments, with EC50 of 0.11 M and 0.07 M, respectively[3].
Naratriptan induces contraction in isolated human epicardial coronary arteries with an EC50 value of 0.17 μM; the maximal contraction induced at this point is 33% of the maximal 5-HT response[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Naratriptan (10 mg/kg; oral; single dose) has an oral bioavailability of 71% in male Wistar rats. Naratriptan (0.5 mg/kg; oral; single dose) has an oral bioavailability of 95% in beagle dogs[3].
Contrary to the activity of μ-opioid receptor agonists, Naratriptan [(10, 30 μg/kg; intrathecal injection; single dose) or (10, 30 mg/kg; subcutaneous injection; single dose)] does not increase the latency of the tail flick response or hot plate response in mice in the tail flick test or hot plate test. Neither or Naratriptan (10, 30 mg/kg; subcutaneous injection; single dose) also does not increase the nociceptive paw pressure threshold in the paw pressure test in guinea pigs and rats[3].
Naratriptan (10 mg/mL; IV/iontophoresis; single dose) inhibits the responses of trigeminal nucleus caudalis neurons to sagittal sinus stimulation in the cat trigeminal neurovascular stimulation model, an effect that can be reversed by the 5-HT1B/1D receptor antagonists (5 mg/mL) SB224289 (HY-101105) and BRL15572 (HY-13200B)[4].
