Abstract
Background:: Aging is a progressive deterioration characterized by the gradual buildup of physiological alterations as time passes. The aging phenomenon encompasses various interconnected systems within the body, such as the skin, bones, cartilage, and hair. Objective and Methods: In this study, based on the appropriate properties of squalene, including antioxidant, anti-inflammatory, and skin repair properties, a molecular docking study was designed for the drug squalene and proteins related to the dermis and epidermis pathway and collagen production (including Col3A1, Col1A2, FBN1, Decorin, and HAS2). Results and Discussion:: The docking results indicated that the interaction of squalene with hyaluronan synthetase 2 (HAS2) possessed the highest negative binding free energy value of -10.90 KCal/mol, followed by decorin with a value of -9.99 KCal/mol. Also, the inhibition constant values of squalene- HAS2 and squalene-decorin complexes were equal to 1.61 and 7.51 μM, respectively. It has been stated that decorin (as a small proteoglycan) and HAS2 are involved in controlling the assembly of skin fibrils and the biosynthesis of glucosaminoglycans, respectively. Conclusion:: Considering that proteoglycans and glucosaminoglycans play a role in the skin aging process, squalene may be used as an anti-aging agent to induce these pathways and for different purposes. Squalene may be used as a potential agent alone or in combination with other compounds in tissue engineering scaffolds for cosmetic, anti-aging, wound healing, and tissue repair applications.
