ZL006

ZL006 is a potent inhibitor of nNOS/PSD-95 interaction, and inhibits NMDA receptor-mediated NO synthesis. In Vitro: ZL006 presents little cytotoxicity, and a growth inhibition of BCECs is not found at low concentration of 0.001, 0.01, 0.1, 1 and 10 μg/mL. The cytotoxicity of T7-P-LPs/ZL006 is significantly enhanced at the concentration of 10 μg/mL. Cellular uptake of ZL006 loads P-LPs and T7-P-LPs after incubation for 0.5 h at the concentrations range from 100 μg/mL to 600 μg/mL in BCECs^[1]. ZL006 does not inhibit the nNOS-PDZ/PSD-95-PDZ interaction, or perturb the nNOS β-finger^[2]. In Vivo: Compared with P-LPs/ZL006 and free ZL006, T7-P-LPs/ZL006 exhibits a significant increase of drug accumulation in the brain tissue due to its better brain targeting delivery. Compared with free ZL006, P-LPs/ZL006 and T7-P-LPs/ZL006 exhibit a significant decrease of drug accumulation in the liver and kidney^[1].
