Design, synthesis, characterization, pharmacological evaluation and in silico ADMET and molecular docking and dynamics simulations of a novel series of N-substituted pyrazole from chalcone derivatives

A novel series of N-pyrazolyl-thienopyrimidine and pyridopyrimidine hybrids was synthesized and characterized using spectroscopic methods. Compounds 4c, 5c, and 12 exhibited superior antibacterial potency compared to Levofloxacin, with molecular docking revealing strong binding to key bacterial targets (e.g., DNA gyrase, Neuraminidase). In-silico ADMET analysis confirmed favorable drug-like properties and low toxicity for 4c, supported by stable molecular dynamics interactions. Additionally, 5c and 12 demonstrated potent anti-inflammatory activity surpassing Celecoxib, with reduced ulcerogenicity. These findings introduce a promising new class of dual-action agents for antibacterial and anti-inflammatory drug development.
