Abstract

In this study, the anti-inflammatory potential of xanthorrhizol (XNT), a natural compound isolated from Curcuma xanthorrhiza, was enhanced through structural optimisation using in silico fragment-based drug design (FBDD) and molecular docking, targeting the hyaluronidase enzyme. The design process yielded five XNT derivatives: one known compound (2) and four novel derivatives (3–6). Derivative (3) exhibited the most favourable druglikeness property and showed the most potent activity (IC₅₀ = 44.54 µg/mL) markedly lower than XNT (1) (IC₅₀ = 203.56 µg/mL). Furthermore, molecular dynamics simulation revealed that derivative (3) maintained a stable interaction within the hyaluronidase binding pocket with key amino acid residues, with a favourable binding free energy of − 26.95 kcal/mol as calculated by the Molecular Mechanics/Generalized Born Surface Area (MM/ GBSA) method. These findings suggest that derivative (3) holds a promise as hyaluronidase inhibitor and potentially to be further developed as anti-inflammatory agent
