Abstract

In the present study, synthesis and characterization of pyrazoline derivatives integrated with sulfonamide scaffold have been performed. The characterization of the molecules was done by elemental analysis, ultraviolet--visible, infrared, nuclear magnetic resonance (NMR), and mass spectra. Crystal structure of compounds 2e and 2g were determined by single crystal X-ray diffraction. In the compounds 2e and 2g, the intra molecular hydrogen bonds N15--H15łdotsO13 and N14--H14łdotsN1 were closed to form a S(6) ring motif, whereas the N14--H14łdotsO17 hydrogen bond links, pairs of molecules related by inversion, forming the familiar R22(10) ring motif. The Hirshfeld surface analysis comprising of the dnorm surface plots, electrostatic potentials and two-dimensional fingerprint plots were generated in order to give visual confirmation of the intermolecular interactions. The molecules were screened for their in vitro antitubercular and antimicrobial activity. The molecules 2n and 2m have shown high potent against M. tuberculosis and most of the molecules have shown good potential against different bacteria and fungi.
