Hexagamavunon (HGV) is a mono-carbonyl analog of curcumin. HGV and its analog have been reported to have activities against gram-positive and gram-negative bacteria, aerobic and anaerobic bacteria, and even have activity against Mycobacterium tuberculosis. HGV antibacterial activity studies have been carried out both in-silico and in-vitro. [30][31][32][33][34] In silico studies, known as molecular docking, are carried out by docking a candidate drug molecule with a target receptor to determine drug-protein interactions. Drug-protein interactions can be used as a basis for predicting the candidate molecular activity and molecular affinity. 35,36 AutoDock Vina is one of the programs used in molecular docking. The advantage of this program is its high speed and accuracy. 37,38 This research explores molecular docking in determining the activity of HGV analogs as anti-H. pylori bacteria by blocking shikimate kinase and urease enzymes.
Materials and Methods
InstrumentsThe molecular docking used a computer with Intel Celeron N3150 1,60 GHz, ram 2GB, and a Windows 8 operating system. The molecular docking procedure was performed using AutoDock Vina software. AutoDock Tools 1.5.6., Open Babel, Marvin Sketch, and Discovery Studio (DS) Visualizer 2016 were used as supporting software.
