トーセンダニン

説明Fructus Meliae Toosendan (chuan lian zi), the fruit of Melia toosendan Sieb. Et Zucc, is mainly produced in Sichuan, Hubei, Henan, and Hunan province in China . Toosendanin is a tetracyclic triterpene compound extracted from fructus toosendan. It is an ascaridole agent and showed anti-botulinum, antibacterial, anticancer, and anti-inflammatory effects. It is also a neuromuscular blocking agent.

来歴Toosendanin is the main chemical composition of the fructus toosendan. Researches on this compound could date back to 1953. Toosendanin has been named in 1955, while its structure was identified 20 years later by mass spectrometry. Toosendanin is a triterpenoid derivative containing a β-substituted furan ring . A new synthetic strategy is put forth allowing access to a 4-acetoxy CD fragment analogue of toosendanin, which was achieved from mesityl oxide and acetylacetone in 14 steps in 2009 . The anti-parasite of toosendanin was reported in 1971. In 1980, it was identified as a selective neuromuscular blocking agent that acts on neuromuscular junction . The anti-botulinum effect of toosendanin was discovered in 1982 . In recent years, it is also observed that toosendanin can induce differentiation and apoptosis . Toosendanin could inhibit the growth of feeding larvae and insects. It has been used as pollution-free, no residue of botanical insecticides for the production of fruits and vegetables in China .

使用Toosendanin is a triterpenoid derivative, acts as a novel agonist of L-type Ca2+ channels in neonatal rat ventricular cells.
