 Objective: The objective of the present study was to synthesize a series of 3-hydroxychromone derivatives and to evaluate its in vitro antioxidant and antimicrobial activities.Methods: 3-hydroxy chromones were synthesized using an algar flynn oyamada method which includes oxidative cyclization of 2-hydroxy chalcones in basic solution by hydrogen peroxide. 2-hydroxy chalcones were synthesized by Claisen-Schmidt condensation of substituted 2-hydroxy acetophenones with substituted aromatic aldehydes using polyethylene glycol-400 as a recyclable solvent. The synthesized compounds were evaluated for in vitro antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl radical scavenging assay. In addition, these compounds were also screened for in vitro antibacterial and antifungal activity by agar cup method and Poison plate method, respectively.Results: The structures of the synthesized compounds were characterized by infrared, 1H nuclear magnetic resonance and mass spectroscopy. The antioxidant activity data revealed that all the synthesized derivatives exhibited good activity due to the presence of phenolic hydroxyl group, 4-oxo group and 2,3-double bond. Further, the activity increased with the introduction of a more phenolic hydroxyl group and adjacent methoxy group in the structure. The antimicrobial activity data showed that the compounds possess better antibacterial and antifungal activity which is attributed to the presence of phenolic hydroxyl group and 4-oxo group in the structure.Conclusions: The use of inexpensive, eco-friendly and readily available reagents, easy work-up and high purity of products makes the procedure a convenient and robust method for the synthesis of title compounds. The presence of phenolic hydroxyl group, 4-oxo group, and 2,3-double bond in the structure is responsible for their good antioxidant and antimicrobial activities.

Cobalt complex with histidine ligand was synthesized and physico-chemically characterized by solubility testing, melting point, UV-spectra and FTIR. The synthesized metal complex was evaluated for in-vitro antibacterial and antifungal activity against the multidrug resistant pathogens, such as Pseudomonas aeruginosa, Vibrio cholerae, Salmonella typhi, E. coli, Klebsiella pneumonia, Staphylococcus aureus, Aspergillus niger, Aspergillus flavus and Candida albicans. The metal complex showed the significant antibacterial and antifungal activity comparison with commercial antibiotics. Further work can be extended through In-silico docking of this metal complex and bacterial, fungal genome which can be given a better idea about genome metal interaction in molecular level.

A series of 2-(6-oxo-5,6-dihydro[1,3]thiazolo[3,2-b]-2-aryloxymethyl-1,2,4-triazol-5-yl)-Narylacetamides 6 were synthesized in good yield by condensing 5-aryloxymethyl-4H-1,2,4-triazole- 3-thiol 5 with various substituted N-phenyl-maleimides in acetic acid media. The newly synthesized compounds were characterized by spectral data and tested for their in vitro antibacterial and antifungal activity against a variety of microorganisms.

New series of fused 1,2,4-triazoles, i.e., 3-(4-isopropylphenyl)-6-substituted phenyl-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazoles (5a-5j) have been synthesized via a four-step procedure and using eco-friendly reaction condition at some steps of the synthesis. It was adopted by the formation of hydrazide of methyl 4-isopropylbenzoate (1) followed by reaction with CS2 in basic media to afford potassium salt, which on cyclized to our essential step, 4-amino-5-(4-isopropylphenyl)-4H-1,2,4-triazole-3-thiol (4). The desired adducts (5a-5j) were formed by (4) on reaction with various aromatic acids in POCl3 media. The newly synthesized triazolo- thiadiazoles have been characterized by different spectroscopic techniques and investigated for their in vitro antibacterial and antifungal activity. It was revealed that the compounds 5a, 5c, 5h, and 5i showed interesting antibacterial and antifungal activity compared to the used reference standard.
