In Vitro In the mouse visual cortex, CGP 55845 hydrochloride (1 μM) increases the frequency of spontaneous Ca2+ transients and spontaneous and miniature IPSCs (mIPSCs) but does not affect mIPSC amplitudes or kinetics. CGP55845 hydrochloride significantly increases evoked IPSC (eIPSC) amplitudes and decreases the paired-pulse ratio (PPR)[3].
In Vivo CGP55845 hydrochloride (i.p.; once; 0.5 mg/kg) treatment increases the number of PSD95 positive puncta as well as density and maturation of dendritic spines in the perirhinal cortex (PRC), and restores novel object recognition (NOR) memory in Cdkl5 KO mice[1]. Animal Model: Cdkl5 +/Y and Cdkl5 -/Y male mice (2-month-old)[1] Dosage: 0.5 mg/kg Administration: i.p.; once Result: Altered NOR recognition memory in Cdkl5 -/Y mice
