of 1,2-disubstituted indazol-3-ones were synthesized by microwave-assisted base-catalyzed cyclization and nucleophilicsubstitution of o-azidobenzanilides. Among five tested reaction conditions, the cyclization of o-azidobenzanilides catalyzed by sodium hydride in DMF, sequentially followed by the nucleophilicsubstitution under microwave irradiation, exhibited the optimal results. Moreover, compared

A number of DNA methylation inhibitors are described. The DNA methylation inhibitors were identified using a two-component enhanced green fluorescent protein reporter system to screen a compound library containing procainamide derivatives. The DNA methylation inhibitors can be used for cancer therapy and prevention.
