Coriandrum sativum improve neuronal function via inhibition of oxidative/nitrosative stress and TNF-α in diabetic neuropathic rats.

Coriandrum sativum L. is traditionally acknowledged for its use in inflammatory disorders, altered blood lipid levels, respiratory and digestive problems, etc. AIM OF THE STUDY: The present study investigates possible role of hydro-alcoholic extract of C. sativum (CHA) seeds in the attenuation of indices of diabetic peripheral neuropathy (DPN).Phytochemical analysis was carried out by employing chromatographic, spectroscopic as well as spectrometric techniques. Diabetes was induced by a single i.p. injection of freshly prepared STZ (65 mg/kg). The indexed markers of DPN, i.e., thermal and mechanical hyperalgesia were found to be prominent on the 60th day of STZ administration. Chronic administration of CHA (100, 200, and 400 mg/kg, p.o.) for 30 days was started on the substantiation of DPN onset. Molecular docking study was performed by targeting TNF-α.Phytochemical analysis revealed the presence of flavonoids, terpenoids, and phenolic acids. Oral administration of CHA considerably attenuated hyperglycemia and decreased pain threshold in diabetic rats as well as modulated oxidative-nitrosative stress. Docking study suggested good affinity of flavonoids when docked into the binding site of TNF-α.In conclusion, using STZ model, it was successfully predicted that CHA might be beneficial in diabetes-induced neuropathic pain by inhibiting oxidative/nitrosative stress and inflammatory cytokine.
