Molecular docking study for evaluation of neuroprotective potential of sericin against cerebral stroke and exploring its biomaterial properties

Abstract

Background: Cerebral stroke, the third leading cause of death worldwide results from the improper blood supply to the brain due to occlusions in the brain arteries. This leads to production of free radicals contributed by cyclo-oxygenases (COX), acid sensing ion channels (ASIC) and matrix metalloproteinases (MMPs) causing adverse conditions of inflammation, oxidative stress, and acidosis leading to neuronal death thereby proving these enzymes as potent targets. Sericin, a 38 amino acid long protein found in silk fiber is known for its anti-inflammatory and anti-oxidant property. Aim and Objectives: Inhibition of the above-mentioned targets by silk protein sericin to reduce the pathological features by structural interactions as well as reducing inflammation and oxidative stress due to the natural properties of compound. Methodology: In the present study we studied structural inhibition of effective targets by sericin through molecular docking analysis. Also, the semi crystalline nature of sericin was deduced through in silico XRD spectral analysis. Result: Structural inhibition through molecular docking analysis proved highly efficient inhibition. Also, the in silico XRD spectral analysis proved sericin to be a potential biomaterial for scaffold development. Conclusion: Sericin can not only act as an effective drug against cerebral ischemia but can also be used to develop scaffold to repair damaged brain.
