Inflammation was signs of pathological or abnormality in tissue to give an alert as a trouble signal to the system. Therapeutic using NSAIDs has some side effects. This research explored the potential role of chlorogenic acid as natural therapeutic compound to inhibit the inflammation target such as COX-2 by interaction model. The research method used in this study was the molecular docking approach, which binds ligand and protein. Protein data provided by Protein Data Bank (ID: 6cox) while, chlorogenic acid obtain from PubChem (CID: 1794427). We docked COX-2 and chlorogenic acid using Hex 8.0.0. Visualization and analysis of the molecular interactions of chlorogenic acid and COX-2 conducted by the Discovery Studio Client 4.1 software. Chlorogenic acid has a high permeability and is easily absorbed based on five Lipinski Rule. Interestingly, we found Fifteen amino acid was binding with chlorogenic acid that formed by hydrogen bond and van der Waals.The interaction between ligand-protein results in energy binding -327.59cal/mol. Chlorogenic acid has a potential role to inhibit inflammation pathway by inhibiting COX-2. We predicted chlorogenic acid has a potential as therapy anti-inflammatory to suppress COX-2 as mediator inflammation.

One of the derivatives of flavonoid explored is chlorogenic acid. Chlorogenic acid has antioxidant and anti-inflammatory activity. Hypertension has support for Angiotensin converting enzyme (ACE) which has a role in regulating the renin-angiotensin system. Hypertension therapy is carried out in inhibit ACE pathway. This study aims to analyse and assess the potential of chlorogenic acid as an antihypertensive material by inhibiting the work of ACE. We used in silico approach to make our model. Chlorogenic acid ligand was obtained from PubChem while ACE was obtained from RCSB. Interaction of ligand and protein using HEX 8.0.0. Analysis and visualization of the results of interactions using Discovery Study Version 4.1. The results showed an interaction between ligand and protein, namely interactions that occur between chlorogenic acid and sixteen amino acid residues. This interaction produces energy of-292.5cal/mol. This interaction approved the ACE block in the AT-I transformation towards AT-II. Chlorogenic acid has potential as an anti-hypertension material.

Type 2 diabetes mellitus (T2DM) is a degenerative disease that leads to increased inflammation and cyclooxygenase protein production, which causes tissue abnormalities. The aim of this study was to determine the effect of caprine CSN1S2 protein against abnormal metabolic pathways in the aorta of DM rats. The twenty-four-animal model was control, diabetes and treatment groups. Histopathological evaluation of the aortic tissue by hematoxylin eosin staining. The expression of cyclooxygenase and inflammatory cytokine was measured by western blotting. In the DM750 groups, the amount of discontinued-endothelial was significantly more reduced than in the other groups. The amount of macrophages in the DM1500-group decreased more than in the DM and DM375 groups. The amount of foam cells in the DM750 and DM1500 groups decreased more than in the DM group and was close to all control groups. The expressions of COX-2 and IL-17 were effectively reduced and vice versa the expression of IL-10 was increased in DM750 compared with the other groups. Meanwhile, COX-1 expression did not change in all groups. This study indicates that caprine CSN1S2 protein at a dose of 750 mg/kg BW has a significant effect on controlling, protecting, and repairing abnormalities in the aortic tissue of T2DM rats.
