PROBLEM TO BE SOLVED: To provide a new composition for treating proliferative diseases, especially various cancers, because many compounds are used for treating cancers and other diseases accompanying cell proliferation, but have side effects, lacks of effective treatments, and the like.SOLUTION: Asiatic acid has a property for injuring cells such as cancer cells, and induces apoptosis in the cells to inhibit the proliferation of the cells. There are also provided a pharmaceutical preparation containing asiatic acid or an asiatic acid glycoside precursor, asiaticoside, for treating the cancers and other proliferative diseases, and use thereof.COPYRIGHT: (C)2012,JPO&INPIT【課題】多くの化合物が、癌および細胞増殖を伴う他の疾患の治療に用いられており、副作用、効果的な治療の欠如などのため、増殖性の疾患、特に多様な癌の治療のための新規組成物を提供する。【解決手段】アジア酸は癌細胞に対し細胞障害性であり、これらの細胞においてアポトーシスを誘導し、細胞の増殖を阻害する。癌および他の増殖性疾患の治療のための、アジア酸またはアジア酸のグリコシド前駆体であるアジアチコサイドを含む医薬製剤およびその使用。【選択図】なし
