Piperidinylindoles

Naratriptan, sold under the brand names Amerge and Naramig among others, is a triptan drug marketed by GlaxoSmithKline and is used for the treatment of migraine headaches. It is a selective serotonin 5-HT1 receptor family agonist.

Sertindole, sold under the brand name Serdolect among others, is an antipsychotic medication. Sertindole was developed by the Danish pharmaceutical company Lundbeck and marketed under license by Abbott Labs. Like other atypical antipsychotics, it has activity at dopamine and serotonin receptors in the brain. It is used in the treatment of schizophrenia.

BRL-54443 is a drug of the piperidinylindole family which acts as a selective agonist for the 5-HT1E and 5-HT1F serotonin receptor subtypes.

LY-334370 is a selective serotonin 5-HT1F receptor agonist of the triptan and piperidinylindole families which was under development by Eli Lilly and Company for the treatment of migraine headaches. The drug showed efficacy in a phase II clinical trial but further development was halted due to toxicity detected in animals. It is closely related to tryptamines like the psychedelic drug dimethyltryptamine (DMT), but is not technically a tryptamine itself and is instead a piperidinylindole similarly to naratriptan.
