Abstract
This invention is about the identification of the HD-2, a natural chemical substance that was separated and purified from a natural product, Sinsuk, as arsenic hexoxide (As.sub.4 O.sub.6) and about its therapeutic efficacy as an anti-cancer drug and pharmaceutical composition. Arsenic hexoxide (As.sub.4 O.sub.6), a natural chemical substance obtained from Sinsuk after eliminating the toxic property, has a potent anti-cancer efficacy by its direct cytotoxicity on tumor cells and suppresses the formation of new blood vessels of tumor masses, which results in complete cure of malignant cancers.
