Abstract
The present work describes the synthesis of novel 3-[2-(5-phenyl-1,3-thiazol-2-yl)hydrazinyl]-1,3-dihydro-2H-indol-2-one derivatives 4(a-h) and the characterization of synthesized hybrids has been done using various spectroscopic techniques like FT-IR, NMR, and HRMS. Through computational study, some global parameters and molecular electrostatic potential (MEP) were analyzed. The solvatochromic UV–Vis absorption study was performed using various solvents and the optical bandgap of the synthesized compounds was determined by using Kubelka–Munk theory. The antimycobacterial activity of the synthesized compounds was evaluated against Mycobacterium tuberculosis and the results suggested that compounds 4d and 4e are effective inhibitors of Mycobacterium tuberculosis. The anti-inflammatory activity against MMP-2 and MMP-9 was determined using gelatin zymography; from the results, it was evaluated that the synthesized derivatives act as good anti-inflammatory agents.
