Dactylicapnosines A () and B (), two reconstructed aporphines with unprecedent five-membered carbon ring D, were isolated from , in which dactylicapnosine A showed potent anti-inflammatory bioactivity . Inspired by its biosynthetic pathway, the total synthesis of dactylicapnosine A via 10 steps has been achieved and afforded enough material to prove its significant anti-inflammatory effect .
达可辛宁 A()和 B(),两个具有前所未有的五元碳环 D 的重建阿朴啡类生物碱,从分离得到,其中达可辛宁 A 表现出很强的抗炎生物活性。受其生物合成途径的启发,通过 10 步反应实现了达可辛宁 A 的全合成,并获得了足够的物质来证明其显著的抗炎作用。
