Abstract
Objective: Investigation of the pharmacological potential of Tetrahydrofurano/pyrano quinoline and Benzo [b]furoindolyl derivatives in acute inflammation, pain and oxidative stress. Methods: Tetrahydrofurano/ pyrano quinoline and Benzo[b]furoindolyl were evaluated for anti-inflammatory activity by carrageenan-induced hind paw edema in rats. Analgesic activity in mice was assessed by both peripheral and central analgesic models. The free radical scavenging activity of the synthetic compound was analyzed by the in vivo antioxidant assays, by measuring the antioxidant enzymes such as Superoxide dismutase (SOD), Catalase and Peroxidase from the liver homogenate and the in vitro antioxidant activity was evaluated by DPPH photometric assay, Hydroxyl radical scavenging and Lipid Peroxidation assay. Results: The compounds had substantially inhibited the inflammation induced by subcutaneous carrageenan injection. The same compounds had demonstrated remarkable central and peripheral analgesic activity with potent free radical scavenging activity as evident from both in vitro and in vivo antioxidant assays. Conclusion: Tetrahydrofurano/pyrano quinoline and Benzo[b]furoindolyl derivatives exhibit varied pharmacological activities that include anti-inflammatory, analgesic and antioxidant activity.
Keywords: Acute inflammation, analgesic, carrageenan, catalase, peroxidase, SOD.
