説明Chelidonine, also named ranunculine, is a kind of alkaloid isolated from the whole plant of Chelidonium majus. L . As a kind of traditional Chinese medicine, Chelidonium majus. L was firstly recorded in Chiu Huang Pen Ts’ao of Ming dynasty. In the seventeenth century, it has been used for the treatment of jaundice, biliary colic, and cholelithiasis. In 1941, a researcher from Soviet Union reported that it showed good effect for the treatment of cutaneous tuberculosis. This plant has multiple effects on different diseases, including anti-inflammatory, analgesia, relieving cough, inducing diuresis, anticancer, antifungal, relieving asthma, and detoxification. It was recorded in the Pharmacopoeia of the People’s Republic of China (1977) .The material basis for Chelidonium majus. L is alkaloid. Among which, chelidonine, a benzophenanthridine alkaloid, is the main effective ingredient . Although great progresses have been made in the chemical synthesis of chelidonine recently, the biosynthetic pathways of chelidonine remain unclear, which still need in-depth study and exploration in the future

来歴Chelidonine was isolated from Chelidonium majus. L in 1824 for the first time. Pharmacological studies found that it exerted antitumor effect via different mechanisms. However, its poor bioavailability limited its application. Some researchers developed a chelidonine/polylactic acid copolymer nanoparticle using nanotechnology. The nano-chelidonine showed good tissue distribution without causing any toxicity in mice and could enter into the brain tissues, showing great application potential. In addition, nano-chelidonine showed protective effect on liver injury induced by cadmium in mice .In 1981, an Austrian researcher isolated a novel compound ukrain (phosphorothioate derivative of chelidonine) from Chelidonium majus. L. Ukrain could inhibit tumor cell proliferation through a variety of mechanisms. Currently, ukrain is used as an antitumor drug for the clinical treatment of lung cancer, breast cancer, prostate cancer, and pancreatic cancer . In 2004, quarter amine chelidonine phosphorothioate derivatives have been applied for an invention patent as anticancer drugs in China.Chelidonine has morphine-like analgesic effects suggesting that its analgesic effect is mainly peripheral and cannot be antagonized by the morphine receptor antagonist naloxone . The 6-alkoxy and 6-acyloxy derivatives of chelidonine can inhibit the central nervous system, especially for nerve terminal, and show sedative and hypnotic effects .
