Abstract: Honey from stingless bee is highly regarded as a medicine in many global communities due to its nutritional and therapeutic value. There is a comparatively restricted amount of research on the biological characteristics of stingless bee honey (SBH) in contrast to Indian bee honey (IBH). Therefore, the objective of this research is to explore the anti-cancer properties of Tetragonula travancorica honey. In the present investigation, antioxidant activity of honey was evaluated using ABTS, DPPH and SOD radical scavenging assays. Anti-proliferative effects was examined on various cell lines using the MTT assay. Liquid chromatography-mass spectrometry (LCMS) analysis was employed to characterize the honey. Binding capabilities of compounds identified in SBH on estrogen receptors (ER) α and ER β were explored through Schrödinger Maestro software. Results indicated that SBH effectively scavenged ABTS, DPPH and SOD free radicals with IC50 values of 22, 36.15, and 79.85 v/v, respectively. SBH exhibited anti-proliferative activity against MCF-7 and HeLa cell lines, with IC50 values of 58.11 and 66.68 v/v, respectively. LCMS analysis, shows the presence of methyl syringate, 2-hydroxycinnamic acid, and fumaric acid in SBH which were not present in IBH. Docking experiments determined that these compounds, with the exception of fumaric acid, interacted stronger with the binding sites of ER β than ER α. The comprehensive findings from antioxidant, anti-proliferative, and docking studies underscore the potential anti-cancer properties of Tetragonula travancorica honey, particularly its heightened cytotoxicity against reproductive system cancer cell lines, such as those in the breast and cervix.
