Micheliolide (MCL) is a sesquiterpene lactone isolated from Michelia compressa and Michelia champaca. Previous studies have demonstrated that MCL exerted various therapeutic effects in cancer, inflammation, immunomodulatory acute myelogenous leukemia and renal fibrosis through numerous signaling pathways, including PI3K/Akt, NF-kB and MAPK signaling. Dimethylaminomicheliolide (DMAMCL), the prodrug of MCL, has been approved by the US Food and Drug Administration for its apparent efficacy in treating pleomorphic glioblastoma. In China, DMAMCL is currently undergoing clinical trials to treat several advanced or metastatic solid carcinomas, including gliomas[2].
Micheliolide (MCL) is a potentially stable sesquiterpene lactone, which can be isolated from Magnolia grandiflora L., Michelia champaca L., and Michelia compressa (Maxim.) Sarg. MCL and its Michael adduct dimethylaminomicheliolide (DMAMCL) display significant cytotoxicity against tumours. MCL is known to be firstly isolated by Ogura, Cordell from Michelia compressa (Maxim.) Sarg. as a cytotoxic active component. MCL is also a main biologically active constituent of Michelia champaca L., Magnolia grandiflora L., and Tanacetum parthenium Sch. Bip., Anthemis scrobicularis Yavin, and Michelia compressa (Maxim.) Sarg[1].
