In vivo study | At doses of 0.1 mg/kg and 0.3 mg/kg, CTEP had a significant effect on the treatment of anxiety in mice. The Vogel drinking water conflict test was performed on rats at 0.3 mg/kg and 1.0 mg/kg doses of CTEP, and it was found that the number of drinking water increased significantly, while there was no effect at the low dose. The Half-Life of oral CTEP was 18 hours and the B/P ratio based on total drug concentration in plasma and whole brain homogenate in mice was 2.6. At separate oral doses of 4.5 and 8.7 mg/kg, suspended in saline or Tween solution and fed to C57BL/6 adult mice, CTEP was rapidly absorbed and maximum efficacy was achieved after approximately 30 minutes. Adult mice are given 2 mg/kg CTEP orally every 48 hours for 2 months of chronic treatment, which can reach the minimum CTEP brain exposure of 240 ng/g. CTEP will completely replace [. Oral administration of 2 mg/kg CTEP to mice twice a day can continuously replace mglu5. In Fmr1 knockout mice, treatment with CTEP (2 mg/kg P. O.) corrects excessive hippocampal long-term inhibitory effects, excessive protein expression, and audiogenic seizures. |
