Prenylated Chromones from the Fruits of and Their Potential Anti-HIV-1 Activities.

(jack tree) is an evergreen fruit tree belonging to the genus (Moraceae), which is widely distributed in subtropical and tropical regions of Asia. Its fruits (jackfruit), well-known as the world's largest tree-borne fruit, are being consumed in our daily diets as a very popular tropical fruit throughout the world and have been confirmed to hold various health benefits. In this study, five new prenylated chromones, artocarheterones A-E (-), as well as seven known prenylated chromones (-) were purified and isolated from the ripe fruits of (jackfruit). Their chemical structures were determined through comprehensive spectroscopic methods. This is the first report on prenylated chromones isolated from The anti-HIV-1 effects of all isolated chromones were assessed . As a result, prenylated chromones (-) showed remarkable anti-HIV-1 effects with EC values ranging from 0.09 to 9.72 μM. These research results indicate that the isolation and characterization of these prenylated chromones with remarkable anti-HIV-1 activities from the ripe fruits of could be significant to the discovery and development of new anti-HIV-1 drugs.
