This study aims to predict the ability of three compounds from Usnea misaminensis to inhibit the COX-2 enzyme as a source of prostaglandins using molecular docking. Receptors obtained from RSCB with PDB ID:5IKR were then prepared on UCSF Chimera 1.16 and the ligands (usnic acid, salizinic acid, and evernic acid) were downloaded 2D structure in .pdbqt format from PubChem. Docking simulation is done via AutoDock Vina 1.1.2 embedded in AutoDockTools 1.5.7. The docking results are visualized using PyMOL 2.5.2 and Biovia Discovery Studio Visualizer. Evernic acid showed binding energy (-6.8 kcal/mol) to the COX-2 receptor which was close to the binding energy value of the control ligand. Usnic acid and salazinic acid showed interactions with the same SER530 residue as the reference ligand. Compounds containing anti-inflammatory effects have the lowest binding energy and bind to residues as reference ligands. These results indicate that the compounds from Usnea misaminensis have potential as anti-inflammatory agents, but further research is needed to examine the potential anti-inflammatory activities.","PeriodicalId":9724,"journal":{"name":"chemistry and materials research","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74290411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Synthesis was performed by reducing Fe2+ ion using polyphenol extract. The extract was obtained from banana peel that abundant in Indonesia and contain high of polyphenols. Synthesis of ZVI was carried out by reacting polyphenol extract to FeSO4 solution with different composition 1:4, 2:3, 1:1, 3:2, 4:1, and 4.5:0.5. The gas chromatography-mass spectroscopy spectrum confirmed the existence of polyphenols in the banana feel extract from the observed peaks assigned to 2-methoxy-4-vinylphenol, 4 methoxy-2-vinylphenol, and 2-methoxy-5-vinylphenol. Based on the atomic absorbtion spectroscopy data, the best composition for ZVI’s synthesis was 4:1 (polyphenol extract : FeSO4 solution). The fourier transform infrared spectroscopy spectrum shows that there was –OH group indicating a present of polyphenol in the synthesized ZVI. The energy dispersive X-ray spectroscopy shows that the sample contain of Fe, C, O, S, Ca, Cu, and Na. The X-ray diffraction analysis exhibit crystalline phase of a simple cubic structure of the synthesized ZVI. This results shows that the ZVI was successfully synthesized using environmentally benign reducing agent extracted from the banana peel.","PeriodicalId":9724,"journal":{"name":"chemistry and materials research","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86586482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
