“…14 INH can form Schiff bases with carbonyl compounds and their metal chelates exhibit anticancer activity. 15 The azomethine derivatives of INH, derived from its condensation with 3,4-dimethoxy benzaldehyde and 3,4,5-trimethoxy benzaldehyde, are known to show antimicrobial activity, 16 while those derived from 3-methoxy-4-hydroxy benzaldehyde and 4-oxypropane benzaldehyde are known as the most potent antioxidants with signicant hydrogen peroxide scavenging ability. 6 The present study throws light on the development of a new catalyst by the modication of y ash, the waste generated in thermal power plants.…”
