Аптиганел
Aptiganel (Cerestat; CNS-1102) je neuspešan kandidat za lek koji deluje kao nekonkurentni antagonist NMDA, a koji je razvijala kompanija Cambridge Neuroscience, Inc kao tretman za moždani udar.[1] On ima neuroprotektivne efekte i istraživan je za potencijalnu upotrebu u lečenju moždanog udara,[2] ali uprkos pozitivnim rezultatima u studijama na životinjama,[3] ispitivanja na ljudima su pokazala ograničenu efikasnost,[4] kao i neželjene nuspojave kao što su sedacija i halucinacije,[5][6] i klinički razvoj ultimatno nije nastavljen.[7]

Neuspeh ovog leka doveo je do kolapsa preduzeća Kembridž neuronauka 1998.[8] i njegove prodaje firmi CeNeS Farmaceutikals 2000. godine.[9]
Druge gvanidinske supstance na kojima je kompanija vršila testove bile su Cns-1145 i CNS1237.
Sinteza
уреди
1-Naftilamin reaguje sa cijanogen bromidom da bi se dobilo jedinjenje 2. Tretman ovog intermedijera sa 3-etil-N-metilanilinom dovodi do dodavanja cijano grupe i formiranja odgovarajućeg diaril gvanidina, aptiganela, 3.
Osobine
уредиAptiganel je organsko jedinjenje, koje sadrži 20 atoma ugljenika i ima molekulsku masu od 303,401 Da.
