Anti-Inflammatory Potential of Selected Indonesian Phytogenic Blends to Nitric Oxide Synthase Inducible Protein in Mojosari Ducks (Anas javanica): In-silico Study

Abstract

Inflammation is a defensive response to tissue damage, infectious agents, and injury. Necrotic enteritis is an inflammatory response induced by pathogenic bacteria invading the intestines of Mojosari ducks (Anas javanica). In contrast, excessive nitric oxide production by inducible nitric oxide synthase during inflammatory processes can cause significant intestinal tissue damage and cellular toxicity. Oxyresveratrol is an active compound of Morus alba that has been known to have antioxidant activity and can suppress the inflammatory process, inhibiting the increased expression of nitric oxide synthase (iNOS). However, unfortunately, this plant is not endemic to Indonesia, so using native Indonesian spices that can be a substitute for oxyresveratrol is necessary. The docking results from nine Indonesian phytogenic blends interacting with NOS revealed that cynaroside from the Piper betle L. plant might be utilized instead of oxyresveratrol as an anti-inflammatory drug via the inhibitory pathway of nitric oxide synthase protein. The docking results showed that from the nine compounds tested, it can be concluded that three compounds were found that are better than the control compound (oxyresveratrol) in terms of binding affinity (energy) and the type of hydrogen bonds bond in amino acid proteins that are equal to the amount more than all compounds tested. The three compounds are cynaroside compounds from Piper betle L. with a binding energy of -9.4 kcal / mol and a Conventional Hydrogen bond type GLU(B):761, GLU(A):761, curcumin compounds from Curcuma longa L. with a binding energy of -8.6 kcal/mol and Conventional Hydrogen bond type GLN(A):760, GLN(B):760 and compound 14-deoxy-11, 12-didehydroandrographolide from Andrographis paniculata with binding energy -8.8 kcal/mol and Conventional Hydrogen bond type GLU(B):761 can be used instead of oxyresveratrol as an anti-inflammatory agent through the inhibition pathway of Nitric Oxide Synthase protein (NOS)
