Plants need to defend themselves from attack by micro-organisms, in particular fungi, and they do this by producing anti-fungal chemicals that are toxic to fungi. Because fungal and human cells are similar at a biochemical level it is often the case that chemical compounds intended for plant defence have an inhibitory effect on human cells, including human cancer cells.〔http://www.ncbi.nlm.nih.gov/pmc/articles/PMC88926/〕 Those plant chemicals that are selectively more toxic to cancer cells than normal cells have been discovered in screening programs and developed as chemotherapy drugs〔http://www.acs.org/content/acs/en/education/whatischemistry/landmarks/camptothecintaxol.html〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Plant sources of anti-cancer agents」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
