Novel 1,2,4-triazole clubbed with 1,3,4-oxadiazole motifs as efficient antimicrobial agents from N-arylsydnone as synthon

1,2,4-Triazoles and 1,3,4-oxadiazoles independently are very important pharmacophores. In view of this, a new class of 1,2,4-triazole clubbed with 1,3,4-oxadiazole motifs have been prepared and characterized by IR, 1H NMR, 13C NMR and mass spectral analysis. Molecular docking of all the title compounds into S. aureus tyrosyl-tRNA synthetase (PDB: 1JIJ) and lanosterol 14α-demethylase complex with standard inhibitor Fluconazole (PDB: 3KHM) was performed which snugly fitted into the active site thus explaining their excellent inhibitory activity exhibiting their possible antibacterial and antifungal activity, respectively. Drug-likeliness, Drug score values and toxicity prediction analyses of all the title compounds have shown favourable values and these molecules belong to Class 4 and Class 5 categories which make them useful scaffolds. Interestingly, the compounds 7h, 7i, 7k, 7u and 7v have exhibited majestic antibacterial activity. Also, these compounds have shown antifungal activity against all pathogenic fungal strains with lower MIC value ranging from 0.50 - 4.00 µg/mL

Synthesis, spectral characterization and antihaemostatic activity of 1,2,4-triazoles incorporating 1,2,4-triazine rings

A simple and high yielding method for the integration of a 1,2,4-triazole ring with 1,2,4-triazine-5-one (4a-j) has been developed starting from 3-arylsydnones (1a-d). The structures were proved by their spectral data and screened for antihaemostatic activity

Synthesis and pharmacological evaluation of 1,5-benzothiazepine derivatives

A simple method for the synthesis of 1,5-benzothiazepines integrated with 5-methyl-2-oxo-3-phenyl-Δ 4-1,3,4-oxadiazoles in 75–95% yield is devised. A comparison of microwave-accelerated reaction with conventional heating is also illustrated. Structures of all the newly synthesised compounds were characterised by physical, analytical and spectral (UV, IR, 1H NMR, and MS) data. Title compounds were screened for their antimicrobial, anticonvulsant, anti-inflammatory, and diuretic activities

An efficient synthesis of novel 3’-substituted 2-aryl-5-methyl-5'thioxo-[4,4'-bi-4H-1,2,4-triazol]-3(1'H, 2H)-ones

Asimple and high yieldingmethod for the integration of two 1,2,4-triazole rings (10a–l) has been developed starting from 3-arylsydnones (1a–d). Confirmation for the structures of the newly synthesised compounds was provided by their physical, analytical and spectral data (IR, 1H NMR, 13C NMR and MS)

Original scientific paper An efficient synthesis of novel 3’-substituted

Abstract: A simple and high yielding method for the integration of two 1,2,4-triazole rings (10a–l) has been developed starting from 3-arylsydnones (1a–d).

Original scientific paper A convenient preparation of novel benzophenone derivatives

Abstract: A simple and high yielding method for the synthesis of novel benzophenone derivatives has been developed starting from ethyl(4-aroylaroxy)acetates. Confirmation for the structures of the newly synthesized compounds was proved by their physical, analytical and spectral data (IR, 1H-NMR, 13C-NMR and MS)

Expedient synthesis of 1,2,4-triazolin-3-one derivatives as DNA cleavage and antioxidant agents

The present study involves the synthesis of fluoren-9-ylidene 5a-e and isoindolin-1,3-dione derivatives 5f-j appended to 1,2,4-triazolin-2-one under solvent and neat conditions. The title compounds have been evaluated for the extent of cell penetration through biological membranes (clogP) and drug score has been calculated and further screened for DNA cleavage and antioxidant activities
