Rationally designed hybrid molecules with appreciable COX-2 inhibitory and anti-nociceptive activities
摘要:
Six molecules were obtained by the combination of three biologically and medicinally significant moieties- indole, chrysin and pyrazole. Bio-evaluation of these hybrid molecules showed significant inhibition of COX-2 enzymatic activity over that of COX-1 and appreciable anti-nociceptive activity, checked at swiss albino mice.

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.
