Description | Ramelteon (TAK-375) is a Melatonin Receptor Agonist. The mechanism of action of ramelteon is as a Melatonin Receptor Agonist. |
In vitro | Ramelteon(0.03 mg/kg和0.3 mg/kg,p.o.)显著缩短了入睡潜伏期,并显著增加了自由活动猴子的总睡眠时间,且不影响猴子的日常行为.腹腔注射给药大鼠10 mg/kg Ramelteon,显著降低降低大鼠的NREM睡眠潜伏期,并且还产生非快速眼动(NREM)睡眠持续时间的短暂增加,但是NREM功率谱未变. |
In vivo | Ramelteon抑制非洲爪蟾的黑色素细胞色素颗粒聚集,pEC50为11.48。1 nM Ramelteon不仅增加MT1/MT2小脑颗粒细胞的ERK1/2磷酸磷酸化,也增加只含一个褪黑激素受体的小脑颗粒细胞的ERK1/2磷酸磷酸化。Ramelteon抑制forskolin刺激的cAMP产生,在CHO细胞中IC50为21.2 pM。 4P-PDOT阻断Ramelteon(1 nM)对MT1 KO小脑颗粒细胞的刺激作用,而luzindole则减弱Ramelteon(1 nM)在MT2 KO小脑颗粒细胞中的作用。Ramelteon与重组人MT1和MT2受体具有高亲和力,pKi分别为10.05和9.70。 |
