Iodine mediated synthesis of some new imidazo[1,2-a]pyridine derivatives and evaluation of their antimicrobial activity

Herein, we reported a series of new 2-(5-methyl-1-aryl-1H-1,2,3-triazol-4-yl)imidazo[1,2-a]pyridines by using iodine and NH₄OAc in good yields. The structures of the titled compounds were characterized by the elemental analysis, ¹H NMR, ¹³C NMR, IR, and mass spectral analysis. All the titled compounds were screened for their in vitro antibacterial and antifungal activities by using streptomycin and Nystatin as standard drugs. The compounds 3k , 3l , 3g , and 3c exhibited potent activity against the tested bacterial strains and 3k , 3l , and 3c exhibited potent activity against the tested fungal strains than the reference drugs.

Microwave assisted synthesis of 4-methyl-3-arylpyrano[2,3-f]chromen-2(8H)-one derivatives,evaluation of antiproliferative,and antimicrobial activities

A series of new 4-methyl-3-arylpyrano[2,3-f]chromen-2(8H)-one derivatives were designed and synthesized through an efficient, an eco-friendly manner under microwave irradiation and conventional heating methods. Structures of final compounds established based on IR, NMR and mass spectral analysis. The final target compounds were screened for their in vitro antiproliferative activity by taking cisplatin as a reference, Further, antibacterial activity by taking strains such as Staphylococcus aureus, Bacillus subtilis, Klebsiella pneumonia and Escherichia coli. Furthermore, antifungal activity screened with Aspergillus niger, Aspergillus flavus and Fusarium oxysporum strains. Many compounds results good activity.
