| Hazard Information | Back Directory | [Uses]
Osavampator (TAK-653) is a AMPA receptor positive allosteric modulator. Osavampator selectively binds to AMPA-R in a glutamate-dependent manner and induces Ca2+ influx in hGluA1i CHO cells (EC50 = 3.3 μM). Osavampator improves learning and memory in many models. Osavampator is can be used for the research of depressive disorders[1][2]. | [Biological Functions]
TAK-653 is a selective positive allosteric modulator (PAM) of AMPA receptors exhibiting minimal agonistic activity, elicits an antidepressant-like response while maintaining a favorable safety profile in rat models.
| [in vivo]
Osavampator (0.03-0.3 mg/kg, p.o., single dose) enhances visual learning and memory in normal rats[2].
Osavampator (0.3 mg/kg, p.o., single dose) enhances sustained attention in the poor performing rats[2].
Osavampator (0.06 mg/kg, p.o., single dose) improves working memory in monkeys[2].
Osavampator (1 mg/kg, p.o., single dose) produces antidepressant-like effects in the rat RSBM (reduction of submissive behavior model)[1]. | Animal Model: | Normal rats[2] | | Dosage: | 0.03 mg/kg, 0.1 mg/kg, 0.3 mg/kg | | Administration: | Oral gavage (p.o.) | | Result: | Improved the novelty discrimination index (NDI). |
| Animal Model: | Poor performing rats[2] | | Dosage: | 0.3 mg/kg | | Administration: | Oral gavage (p.o.) | | Result: | Increased correct responses and decreased omissions in the poor performing rats. |
| Animal Model: | Fasted monkey[2] | | Dosage: | 0.06 mg/kg | | Administration: | Oral gavage (p.o.) | | Result: | Significantly increased delayed match-to-sample (DMTS) accuracy at a 16-s delay interval.
Maintained the beneficial effect 24 h after administration. |
| Animal Model: | submissive behavior model [1] | | Dosage: | 0.1 mg/kg, 1 mg/kg | | Administration: | Oral gavage (p.o.) | | Result: | Led to a significant reduction in dominance levels compared with vehicle treatment starting from the seventh day of treatment and maintained throughout the study period.
Had a significant effect in reducing dominance levels at 0.1 and 1 mg/kg.
