Abstract Biologically potent complexes of aluminum(III) and gallium(III) derived from semicarbazone of 3-acetylcoumarin have been synthesized under microwave irradiation and investigated using a combination of microanalytical analysis, melting point, ultraviolet spectra, infrared spectra, 1H nuclear magnetic resonance (NMR) spectra, and 13C NMR spectra. Aluminum and gallium isopropoxides interact with the ligand, resulting in the formation of colored products. Based on conductance and spectral evidences, a five-coordinated structure for aluminum(III) and gallium(III) complexes has been assigned for 1:1 ratio and a six-coordinated structure for 1:2 and 1:3 ratios. The ligand is coordinated to the aluminum(III) and gallium(III) via the azomethine nitrogen atom and the enolic oxygen atom. The free ligand and its metal complexes have been tested in vitro against a number of pathogenic microorganisms in order to assess their antimicrobial and pesticidal properties. Both the ligand and its complexes were found to possess appreciable bactericidal and pesticidal properties.

AbstractNew thiazole-substituted dibenzofurans 7a–j were synthesized from dibenzofuran derivatives 5a–b and substituted thiosemicarbazones 6a–h under conventional and microwave irradiation conditions. The structures of all products were established on the basis of analytical and spectral data. The synthesized compounds were evaluated for their in vitro antibacterial activity against Gram-positive and Gram-negative strains. Compounds 7b, 7d and 7h are active against Bacillus subtilis (+ve), and compound 7i displays good activity against Pseudomonas aeruginosa (-ve) strain. Compounds 7a–j were also evaluated for their in vitro antimycobacterial activity, and compound 7b shows antimycobacterial activity against Mycobacterium bovis strain.

Herein we report an alternative eco-friendly method for the synthesis of 1,2,3,4-tetrahydroisoquinoline sulfonamide derivatives. All obtained compounds were screened for their in vitro inhibition of albumin denaturation, antioxidant, antitryptic, and antibacterial activity and have shown significant results. The lipophilicity was established using both reversed-phase thin layer chromatography and in silico calculations.
