Biochem/physiol Actions

Indiplon (NBI 34060) is an orally active, high-affinity GABAA receptor positive allosteric modulator (PAM) with preferential labeling of alpha1 subunits-containing receptors (rat cerebellar/cerebral cortex membranes binding KD = 1.01/0.45 nM). Indiplon potentiates GABA-induced chloride conductance of cultured rat cortical neurons (EC50 = 11.6 nM vs 152 nM/630 nM) and exhibits sedative efficacy in mice (ED50 = 1 mg/kg/passive avoidance & 2.7 mg/kg/locomotor activity inhibition po.) and rats (ED50 = 2.5 mg/kg/locomotor activity inhibition & 3 mg/kg/vigilance impairment po.) in vivo. Indiplon shows greater affinity, in vitor and in vivo potency than zaleplon and zolpidem.

Indiplon (NBI 34060) is a novel pyrazolopyrimidine currently in development for the treatment of insomnia. We have previously shown that indiplon exhibits high-affinity binding to native GABA(A) receptors from rat brain and acts as a positive allosteric modulator of GABA(A)

Ionotropic GABAA receptors expressing at the axon initial segment (AIS) of glutamatergic pyramidal cell (PC) in the cortex plays critical roles in regulating action potential generation. However, it remains unclear whether these receptors also express at the AIS of cortical

The mechanisms commanding the activity of dopaminergic neurons of the ventral tegmental area (VTA) and the location of these neurons are relevant for the coding and expression of motivated behavior associated to reward-related signals. Anatomical evidence shows that several brain

Converging epidemiological studies indicate that cannabis abuse during adolescence increases the risk of developing psychosis and prefrontal cortex (PFC)-dependent cognitive impairments later in life. However, the mechanisms underlying the adolescent susceptibility to chronic cannabis exposure are poorly understood. Given that

Indiplon (NBI 34060; N-methyl-N-[3-[3-(2-thienylcarbonyl)-pyrazolo[1,5-alpha]pyrimidin-7-yl]phenyl]acetamide), a novel pyrazolopyrimidine and high-affinity allosteric potentiator of GABA(A) receptor function, was profiled for its effects in rodents after oral administration. In mice, indiplon inhibited locomotor activity (ED(50) = 2.7 mg/kg p.o.) at doses lower than
