Avitriptan (INNTooltip International Nonproprietary Name; development codeBMS-180048) is anantimigraine drug of thetriptan family which was never marketed.[1] It acts as aserotonin5-HT1B and5-HT1D receptoragonist.[1][2] The drug reachedphase 3clinical trials prior to the discontinuation of its development.[3]

Avitriptan acts as aselectiveserotonin5-HT1B and5-HT1D receptoragonist.[1][2] It is also notable in being a weak serotonin5-HT2A receptor agonist (EC50Tooltip half-maximal effective concentration = 123 nM), albeit with about two orders of magnitude lower activational potency than at the serotonin 5-HT1B and 5-HT1D receptors.[2]

Besides its activities atserotonin receptors, avitriptan has been found to act as a weakaryl hydrocarbon receptor agonist.[5]

Chemistry

[edit]

Avitriptan is atriptan and amodifiedanalogue oftryptamines like thepsychedelic drugdimethyltryptamine (DMT).[6] However, avitriptan itself is not technically a tryptamine as it features apropylamineside chain instead of theethylamine side chain present in tryptamines.[6] Besides this difference, avitriptan is substituted at the 5 position of theindolering system and theaminemoiety has beencyclized and extended.[6]

The predictedlog P of avitriptan is 1.8.[6]
