Garmultins A and B (1 2), two polycyclic polyprenylated acylphloroglucinols characterized by the coupling of novel cages, 2,11-dioxatricyclo[4.4.1.03,9]undecane tricyclo[4.3.1.03,7]decane, along with five biogenetically related analogues (3-7), were isolated from Garcinia multiflora. Their structures absolute configurations determined extensive NMR analysis, X-ray crystallography, electronic circular dichroism calculations. Three compounds capable inhibiting oncogene expression inducing apoptosis in human erythroleukemia cells.
