Isatin (2,3-dioxindole) and its derivatives show a wide range of biological activities. In the present study, a series of Schiff and Mannich bases of isatin derivatives were prepared using 4-amino-5-benzyl-2,4-dihydro-3H-1,2,4-triazole-3-thione. The structures of these derivatives were characterized by IR, 1H NMR and elemental analysis. In vitro(More)
Newly designed coumarinyloxy acetamide derivatives (7a–7n) were synthesized in good yields and characterised by advanced spectroscopic studies and the XRD studies indicated that no polymorphism is observed in the molecules. Synthesized coumarinyloxy acetamides showed potent antimicrobial activity on human pathogens. Some of the analogues were found to have(More)
