In vitro and In silico approach in Evaluating the Immunomodulatory potential of Ethanol extract of Sinapis alba Linn. seed.

Sinapis alba Linn., one of the traditionally used medicinal plant was analyzed for the immunomodulatory potential using in vitro and in silico approach. In vitro immunomodulatory analysis of S. alba ethanol seed extract was evaluated using NO (Nitric Oxide) and phagocytic assay determination assay with Raw 264.7, macrophage cell line. Result showed that there was a significant induction in NO production with 40.18% at 12.5μg/ml and maximum phagocytic stimulation of 83.08% at 12.50μg/ml. Gas Chromatography Mass Spectrometry analysis of ethanol seed extract of S. alba showed presence of 13 phytocomponents. Ligands were prepared from these 13 components. Compounds passing in-silico drug-likeness were subjected to molecular docking analysis with target protein 4NKQ (Macrophage colony stimulating factor protein). Among the 13 phytocomponents, Ethyl 13-docosenoate (ethyl erucate) bound with high docking score of 142.43 at the active site 2 with five hydrogen bonds. The findings thus suggest that S. alba possess immunomodulatory potential and the compound Ethyl 13-docosenoate (ethyl erucate) could be further investigated for incorporation in pharmaceutical applications.
