Candidiasis incidence has increased, mostly due to the use of plastic permanent catheters, antibiotics and immunosuppressive drugs. These Candida-derived infections may occur in the skin, mucous membranes and viscera, with the main etiological agent being Candida albicans. Gallic acid (GA), is a polyphenol acid compound and it is ubiquitous in fruits, vegetables, and herbal medicines, such as grapes, gallnuts, pomegranates, and tea leaves. The RCh1P protein was modelled using Swiss-Model online server program. Phytochemicals identified from honey namely, caffeic acid and gallic acid, were selected for the study. Molecular docking was carried out using Hex Protein Docking server. The structures were viewed, and analysed for polar hydrogen atoms, and identification of binding residues was carried out using PyMOL program ver. 2.4.0. Interaction of the drug including gene expression, possible adverse effects and side effects were predicted using pass online web server. The physiochemical properties, lipophilicity, water solubility, pharmacokinetics and drug-likeliness were assessed using SwissADME online sever program. The highly negative E-total scores as a result of molecular docking of Gallic acid and caffeic acid with RCh1P plasma membrane protein of Candida species, demonstrates the inhibitory activity of the phytochemicals on the growth of the fungus. This study indicates that the effect of Gallic acid and Caffeic acid on plasma membrane protein RCh1P is inhibitory.
