Abstract
Piperazine is a six-membered heterocyclic ring with two nitrogen atoms at positions one
and four. This piperazine moiety can be present in a slew of well-known medicines that have pharmacophoric
effects on a variety of receptors. Various piperazine analogs have core biological activities
involving the activation of monoamine pathways, primarily on neurotransmitter receptors. As a result,
piperazine analogs have a wide range of central clinical uses, including anxiolytic, antipsychotic, and
antidepressant. Due to its stimulant and euphoric effects, benzyl-piperazine is the prototype of piperazine
analogs, and this molecule is the main substance of recreational drugs. This review focuses on
the activity of piperazine pharmacophore on diverse neurotransmitter receptors used therapeutically
as anxiolytics (buspirone), antidepressants (vortioxetine), antipsychotics (clozapine), and other drugs.
Keywords:
Piperazine, heterocyclic ring, pharmacophore, pharmacological activities, neurotransmitter receptors, derivatives.
