Preparative-scale synthesis of ZL006 and its derivatives

Disrupting the nNOS-PSD95 interaction could selectively inhibit the NMDARs-nNOS signal pathway, without blocking NMDARs function and catalytic activity of nNOS, thereby sparing unwanted effects on many other important physiological processes mediated by the NMDARs and nNOS.In this protocol, 4-\ (3,5-Dichloro-2-hydroxybenzylamino)-2-hydroxybenzoic acid, a nNOS-PSD95 interrupter, we named it ZL006, was prepared by the condensation of 3,5-dichlorosalicylaldehyde and 4-aminosalicylic acid, and the reduction of the condensation production with sodium borohydride.We synthesized the derivatives of ZL006 also.
