| Hazard Information | Back Directory | [Description]
P7C3-A20 is a derivative of P7C3 (Item No. 16682) that has proneurogenic and neuroprotective activity. It increases proliferation in the subgranular zone (SGZ) of the adult mouse dentate gyrus in a dose-dependent manner when administered at doses ranging from 0.1 to 10 μM. It also protects U2OS cells from calcium-induced mitochondrial dissolution. In a rat model of traumatic brain injury, P7C3-A20 (10 mg/kg, i.p., twice daily for one week) decreases contusion volume, increases proliferation in the SGZ, and decreases the latency to reach the platform in the Morris water maze to sham surgery control levels. It also prevents or reverses dopaminergic cell death and motor deficits in a 6-OHDA rat model of Parkinson's disease. | [Uses]
P7C3-A20 is a derivative of P7C3 with potent proneurogenic and neuroprotective activity. P7C3-A20 exerts an antidepressant-like effect. P7C3-A20 can cross the blood-brain barrier and therefore has the potential for brain injury treatment[1][2][3]. | [Synthesis]
To a vial containing N-(3-(3,6-dibromo-9H-carbazol-9-yl)-2-fluoropropyl)-N-(3-methoxyphenyl)-4-nitrobenzenesulfonamide (21.0 mg, 0.030 mmol) were added lithium hydroxide (3.2 mg, 0.134 mmol), N,N-dimethylformamide (0.5 mL, 0.06 M), and mercaptoacetic acid ( 4.2 μL, 0.060 mmol). The reaction mixture was stirred for 1 h at room temperature, then diluted with ethyl acetate and washed sequentially with water, saturated sodium bicarbonate solution, water (3 times) and brine. The organic layer was dried with anhydrous sodium sulfate, filtered and concentrated. The crude product was purified by silica gel column chromatography (eluent: 30% ethyl acetate/hexane containing 0.2% triethylamine) to give 13.6 mg of the target compound in 88% yield.
Another synthetic method: DAST (diethylamino sulfur trifluoride, 0.12 mL, 0.916 mmol) was added dropwise to a solution of 1-(3,6-dibromo-9H-carbazol-9-yl)-3-(3-methoxyphenylamino)propan-2-ol (0.102 g, 0.203 mmol) in anhydrous dichloromethane (6.0 mL), and the reaction was carried out at -78 °C. The reaction mixture was stirred at -78 °C for 1 h, then slowly warmed to 0 °C and kept for 5 h. The reaction was carried out at -78 °C. The reaction was quenched by addition of phosphate buffer (pH=8) and extracted with dichloromethane. The aqueous phase was extracted twice with dichloromethane (10 mL). The combined organic phases were dried with anhydrous sodium sulfate, filtered and concentrated. The crude product was purified by silica gel fast column chromatography (eluent: 20% ethyl acetate/hexane containing 0.2% triethylamine) and the fraction containing the desired fluorinated product was further purified with 40% ethyl acetate/hexane containing 0.1% triethylamine to give 5.7 mg of the target compound.

P7C3-A20 (5-10?mg/kg; intraperitoneal injection; daily; for 7 days; Sprague-Dawley rats) treatment reduces infarct volume; reverses cell loss in the cortex and hippocampus and improves motor function without causing neurotoxicity in HI model rats. P7C3-A20 prevents HI-induced neuronal injury via activation of the PI3K/AKT/GSK3β signaling pathway[1]. | Animal Model: | Sprague-Dawley rats (200-250 g) induced hypoxic-ischemic (HI) injury [1] | | Dosage: | 5?mg/kg, 10?mg/kg | | Administration: | Intraperitoneal injection; daily; for 7 days | | Result: | Reduced infarct volume; reversed cell loss in the cortex and hippocampus and improved motor function without causing neurotoxicity.
