9-Hydroxycalabaxanthone exhibits cytotoxicity against the HT-29 cell line with ED50 values of 9.1 microM. The combination of 9-hydroxycalabaxanthone with α±-mangostin shows the synergistic antimalarial interaction in both clones.

Their structures were elucidated on the basis of IR, UV, 1D, 2D NMR, and MS spectroscopic data, in addition to comparison with literature data. The isolated compounds were evaluated for their antioxidant, antimicrobial, and quorum-sensing inhibitory activities. Compounds 3 and 5 displayed promising antioxidant activity with IC50 12.07 and 14.12 μM, respectively using DPPH assay. Compounds 4-6 had weak to moderate activity against Escherichia coli and Staphylococcus aureus, while demonstrated promising action against Bacillus cereus with MICs 0.25, 1.0, and 1.0mg/mL, respectively[1]
