Osthol

BeschreibungCnidium is a Chinese medicine which is used widely by traditional medicine doctors. Cnidium has been recorded in almost all of the pharmaceutical monographs , including Shen Nong’s Classic Materia Medica, New Materia Medica, Compendium of Materia Medica, etc. Osthole is a major bioactivity compound of the Cnidium, which has the effect of dampness dispelling, insecticidal antipruritic,and aphrodisiac and is used for the treatment for pruritus and eczema, lumbago,kidney impotence, and infertility . Osthole is derived from Umbelliferae and Rutaceae plants. Osthole is also distributed in Asteraceae and Leguminosae plants. Osthole is present in 14 genera of Umbelliferae plants: danggui (Angelica L.), gudanggui (Archangelica Hoffm.), mianguoqin (Cachrys L.), shechuang (Cnidium Cusson), awei (Ferula L.), duhuo (Heracleum L.), yanfeng (Libanotis Hill), ouqin (Petroselinum Hill), qianhu (Peucedanum L.), huiqin (Pimpinella L.), liangshechuang (Selinum L.). Shuanchiqin (Prangos Lindl), xifengqin (Seseli L.), oufangfeng (Pastinaca L.). Osthole is present in 17 genera of Rutaceae plants: ganju (Citrus L.), huangpi (Clausena Burm. F.), xiangju (Feronia Correa), jupanmu (Flindersia R. Br.), niyunxiang (Haplophyllum A. Juss.), mizhuyu (Melicope J. R. and G. Forst.), xiaoyunmu (Micromelum Bl.), jiulixiang (Murraya Koenig ex L.), zhi (Poncirus Raf.), yinyu (Skimmia Thunb.), Limonia, Myrtopsis, Pentaceras, Phebalium, Pilocarpus, Thamnosma, Ticorea) .

HistoryCnidium is a Chinese medicine which is used widely by traditional medicine doctors. Osthole was isolated in 1950 and then its chemical structure was determined . Osthole can be extracted by solvent method, acid-base method, ultrasound, and supercritical and other methods. The main methods for the separation of osthole are recrystallization, chromatography, and so on. With the development of modern pharmacological experimental methods and techniques, the pharmacological effects of osthole have been discovered and developed. It is found that osthole has many pharmacological activities such as anti-osteoporosis, antiplatelet aggregation, antiviral, anti-mutation, anti-allergic reaction, and so on. In recent years, it has been found that osthole has obvious antitumor activity. In addition, osthole also has strong insecticidal and antifungal effects. In the future, osthole is expected to be developed as a new kind of low-toxicity, high-efficiency, and lowresidue pesticide.

VerwendenOsthole inhibits the PI3K/Akt pathway thus inhibiting insulin-like growth factor-1 (IGF-1)-induced epithelial-to-mesenchymal transition (EMT) in brain cancer. Osthole may be used in the treatment of Glioblastoma multiforme (GBM).
