Mechanism of Action

Targets/IC₅₀/Ki	5-HT2 ^[1]
In vitro	Clozapine (10, 20 mg/kg) significantly increases the number of Fos-positive neurons in the nucleus accumbens, medial prefrontal cortex and lateral septal nucleus. ^[1] This compound induces zif268 but not c-fos mRNA in rat striatum, while Haloperidol induces c-Fos-like immunoreactivity in the caudate-putamen. ^[2] It is more selective for D4 receptors compared to D2 receptors. This chemical is a mixed but weak D1/D2 antagonist. ^[3] It produces a marked facilitation (300-400%) of NMDA-evoked responses in a concentration-dependent manner with EC50 of 14 nM. This compound, but not haloperidol, produces bursts of excitatory postsynaptic potentials (EPSPs), which are blocked by glutamate receptor antagonists, suggesting that these EPSPs are the result of increasing release of excitatory amino acids. ^[4] It is a full agonist at the muscarinic M4 receptor (EC50 = 11 nM), producing inhibition of forskolin-stimulated cAMP accumulation. This chemical potently antagonizes agonist-induced responses at the other four muscarinic receptor subtypes. ^[5]
In vivo	Clozapine exhibits an "inverted-U" shaped dose-response curve, reversing the apomorphine-induced loss of prepulse inhibition (PPI) at low doses but not at high doses in the rats. This compound decreases PPI independent of apomorphine treatment in the rats. ^[6]
