Molindone hydrochloride exerts its effect by blocking dopamine receptors, probably D2 and D3, in the reticular activating and limbic systems, thereby decreasing dopamine excess in the brain.

(Molindone Hydrochloride, NCI Thesaurus)

By modulating binding of the GABA inhibitory neurotransmitter to GABA-A receptors in the ascending reticular activating system, flurazepam blocks arousal of the cortical and limbic system, thereby exerting its sedative and hypnotic effect.

(Flurazepam, NCI Thesaurus)

Estazolam binds to the gamma-aminobutyric acid (GABA) receptor at a site distinct from the inhibitory neurotransmitter GABA binding site in the limbic system of the central nervous system (CNS).

Fluphenazine blocks postsynaptic dopamine D2 receptors in the limbic system, cortical system and basal ganglia, resulting in a reduction of schizophrenia-associated hallucinations and delusions.

(Fluphenazine hydrochloride, NCI Thesaurus)

Diazepam potentiates the inhibitory activities of gamma-aminobutyric acid (GABA) by binding to the GABA receptor, located in the limbic system and the hypothalamus.

Although the exact mechanism of meprobamate is largely unknown, it appears to act as a depressant at multiple sites in the central nervous system, mostly likely through the GABAergic neurotransmitter system, including the thalamus and limbic system.
