Brexpiprazole HCl (OPC 34712 dihydrochloride) is a new antipsychotic drug.

Brexpiprazole (OPC-34712) is a partial agonist of human 5-hydroxytryptamine (5-HT) 5-HT1A and dopamine D2 receptors.

UoS 12258 is a selective and efficient AMPA receptor positive allosteric modulator, reversing acute and subacute drug-induced deficits in rat novel object recognition, used to study cognitive disorders.

Trofinetide, derived from the neuroprotective tripeptide Gly-Pro-Glu (an N-terminal sequence of insulin-like growth factor-1, IGF-1), shows promise in various neuroprotective models. At a concentration of 10 nM, it mitigates cell death in primary rat embryonic striatal neurons caused by okadaic acid. Additionally, Trofinetide reduces the expression of pro-inflammatory markers (IL-1β, TNF-α, IL-6, and E-selectin) in a rat model simulating neuroinflammation from penetrating ballistic-like brain injuries. In cases of brain injury induced by middle cerebral artery occlusion (MCAO), administration of Trofinetide at 30 and 60 mg kg reduces the area of cortical and striatal infarct. Furthermore, a daily dose of 100 mg kg reverses social recognition and contextual fear conditioning deficits, diminishes the number of dendritic spines, and decreases testicular weight gain in an fmr1- - knockout mouse model of fragile X syndrome. Trofinetide formulations have been employed in treating Rett syndrome, highlighting its versatility across various neurological conditions.

Z944 is a T-type calcium channel antagonist with potential applications in pain management. In both epileptic and non-epileptic rats, Z944 disrupts prepulse inhibition. Additionally, it corrects cross-modal sensory and visual recognition memory deficits in Strasbourg genetic absence epilepsy rats. In a neuropathic pain rat model, Z944 restores cortical synchrony and thalamocortical connectivity. In the amygdala kindling model, it delays seizure progression.

PZ-1922 (Compound 16), able to cross the blood-brain barrier, is a dual antagonist for 5-HT6R and 5-HT3R with K i values of 17 nM and 0.45 nM, respectively. It also reversibly inhibits MAO-B with a pIC50 of 8.93. Moreover, PZ-1922 mitigates scopolamine (SCOP)-induced memory deficits in rats as observed in the novel object recognition (NOR) test and hinders Aβ-induced memory impairment in the T-maze test [1].
