TAK-915 是一种有效的，选择性的，可透过血脑屏障和口服活性的 PDE2A 抑制剂，IC50 为 0.61 nM。TAK-915 对 PDE2A 的选择性是 PDE1A 的 4100 倍以上。TAK-915 可用于神经精神疾病和神经退行性疾病的研究。
TAK-915 is a potent, selective, brain-penetrant and orally active phosphodiesterase 2A (PDE2A) inhibitor with an IC50 of 0.61 nM. TAK-915 is >4100-fold more selectivity for PDE2A than PDE1A. TAK-915 has the potential for neuropsychiatric and neurodegenerative disorders treatment[1][2].
TAK-915 (3 mg/kg; oral administration; daily; for 4 days; male F344 rats) treatment significantly reduces escape latency in aged rats in the Morris water maze task[2].TAK-915 (1, 3, and 10mg/kg, p.o.) dose-dependently attenuates the non-selective muscarinic antagonist scopolamine-induced memory deficits in rats[2]. Oral dosing of TAK-915 (compound 36) (3 or 10 mg/kg) in mice produces a dose-dependent increase in 3’,5’-cyclic guanosine monophosphate (cGMP) levels, with significant cGMP increases observed at a dose of 10 mg/kg[1].
