Two new chlorine-containing polyoxygenated seco-cyclohexenes, albanols A (1) and B (2), along with the oxepinone metabolite grandiuvarone (3) were isolated from the endemic Philippine Annonaceae plant Uvaria alba. Both new compounds exhibited modest antitubercular activity. Compound 1 showed cytostatic activity (ranging from 1–50 μM) against HeLa cells and weak antiproliferative activity against HUVEC and K-562 cells with GI₅₀ values of 106 and 81 μM, respectively.
