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 Cu(I)-catalyzed 1,3 oxo alkylation of indazole has been developed for constructing N-1-alkylated indazolone derivatives. This cascade reaction involves the formation of C−N and C−O bonds through the sequential functionalization of N1 and C3 positions of indazole in 41–89% yields. The photo-physical studies of the synthesized compounds showed efficient quantum yields with high Stoke shift values.
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.
