ASP8062
ASP8062 is an orally active, blood-brain barrier-permeable selective GABAB receptor allosteric modulator. ASP8062 enhances GABA-mediated activation of GABAB receptors and strengthens GABAergic neurotransmission. ASP8062 reverses Reserpine (HY-N0480)-induced myalgia, regulates the sleep-wake cycle, increases delta wave power during non-REM sleep, and impairs motor coordination at high doses. ASP8062 penetrates the central nervous system with a half-life of 40-50 h. ASP8062 can be used in research related to opioid use disorder, fibromyalgia, chronic pain, and alcohol use disorder[1][2][3][4].

GABAB receptor |
ASP8062 acts as a positive allosteric modulator to enhance the potency and maximal response of transfected cell lines stably expressing human or mouse GABAB1c/2 receptors across a wide range of GABA concentrations[2].
ASP8062 exhibits limited to no inhibitory effects on CYP2C9, CYP1A2, CYP2B6, CYP2C8, CYP2C19, CYP2D6, and CYP3A enzymes in human liver microsomes[2].
Metabolism of ASP8062 in liver tissue fractions from mice, rats, rabbits, dogs, monkeys, and humans is mediated primarily by CYP3A4 and secondarily by CYP2D6[2].
ASP8062 (0.003-1 μM) acts as a positive allosteric modulator for both human and rat GABAB receptors in HEK293 cells, decreasing GABA's EC50 and increasing its maximal calcium mobilization response at concentrations of 0.003, 0.3, and 1 μM[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
ASP8062 (10 mg/kg; p.o.; single administration; administered immediately after subcutaneous injection of 10 mg/kg morphine) does not potentiate morphine-induced respiratory depression in cynomolgus monkeys[1].
ASP8062 (0.01-10 mg/kg; p.o.; single administration; once daily for 6 consecutive days) exerts significant analgesic effects in a rat fibromyalgia model at oral doses of 0.03, 0.1, 1, and 10 mg/kg, and maintains sustained efficacy after 6 consecutive days of administration[3].
ASP8062 (3-100 mg/kg; p.o.; single administration) impairs motor coordination in normal rats only at the oral dose of 100 mg/kg[3].
ASP8062 (1-10 mg/kg; p.o.; single administration) modulates the sleep architecture of normal rats at an oral dose of 10 mg/kg, reduces rapid eye movement (REM) sleep and sleep fragmentation, and enhances delta wave power during non-rapid eye movement (NREM) sleep[3].
ASP8062 (1-10 mg/kg; p.o.; once daily; for 4 consecutive days) significantly reduces all indicators of operant voluntary alcohol intake in male Sprague Dawley rats without inducing non-specific motor effects, with the highest dose yielding the best therapeutic efficacy[4].
ASP8062 (1-10 mg/kg; p.o.; once daily; for 4 consecutive days) significantly reduces operant alcohol self-administration behavior in female Sprague Dawley rats without inducing non-specific motor effects, with the 3 mg/kg and 10 mg/kg doses showing the strongest efficacy in lever pressing and nose poke entry measures[4].
