Abstract
A new method for synthesizing 4-amino-3-methyl-1-phenyl-1H-5-substituted thieno[2,3-c]pyrazole was reported. The substituted groups at position 5 include carbonitrile, carboxamide, N-phenyl carboxamide, and benzoyl groups. The newly synthesized compounds and their derivatives were characterized by elemental analysis and spectroscopy (IR, 1H NMR, and mass spectra). Furthermore, some of these synthesized compounds were screened against various pathogenic bacterial and fungal strains. The results demonstrate that most of the synthesized compounds possess a significant antibacterial activity against grampositive and gram-negative bacteria. In addition, most of these compounds showed a remarkable anti-fungal activity. On the other hand, some of the synthesized compounds possess high anti-inflammatory activity, which was demonstrated using the carrageenan-induced rat paw edema assay.
