Triblock Conjugates: Identification of a Highly Potent Antiinflammatory Agent
摘要:
Rationally designed conjugates of chrysin, indole, and barbituric acid were synthesized and screened for their antiinflammatory activities through in vitro and in vivo experiments. Improved over the previously reported chrysin indole pyrazole conjugates and also in comparison to the chrysin, indole, and barbituric acid based COX-2 inhibitors, the new compounds have displayed significantly better IC50 for COX-2 and some of them also exhibited inhibition of 5-LOX enzyme. For one of the test compounds, IC50 for COX-2 and 5-LOX was 1 and 1.5 nM, respectively. Investigations of Swiss Albino mice through capsaicin induced paw lickings and dextran induced inflammation showed that these compounds possess appreciable analgesic and antiinflammatory activities. K-i, K-a, and Delta G for the enzyme compound interaction were calculated and found to be in agreement with The experimental results were supported by the molecular docking studies of the compounds in the active site of COX-2 and 5-LOX. Overall, a highly promising antiinflammatory agent was identified. the biological data.

bis-indolylimidazole derivatives usingZn2+ supported on montmorillonite KSF (Zn2+@KSF) as an efficient heterogeneous catalyst is described. The structures of these compounds were characterized by IR, 1H NMR and 13C NMR spectroscopy. The antibacterialactivity of the selected products was examined. Some products exhibit promising activities. Graphical Abstract One-potMulti-componentSynthesis of Mono- and Bis-indolylimidazole

The structure of the products was confirmed by Fourier-transform infrared (FT-IR), 1H nuclear magnetic resonance (NMR), and 13C NMRspectra. All synthesized compounds were evaluated for in vitro antibacterial activity against Gram-positive (Bacillus subtilis and
