(+)-Muconin (1), isolated from the leaves of Rollinia mucosa (Jacq.) Baill. (Annonaceae), is a sequential THF/THP-possessing acetogenin that exhibits potent and selective in vitro cytotoxicity toward pancreatic and breast tumor cell lines. In this study, a new route was established for obtaining (+)-muconin (1) starting with (-)-muricatacin (2), a compound recently synthesized via the novel alpha-C-H hydroxyalkylation and alpha'-C-H oxidation of tetrahydrofuran.

异戊二烯基
苯丙素,其具有抗结核杆菌活性。采用反相高效
液相色谱法对Muconin进行了分离纯化,然后通过质谱和核磁共振光谱等方法对它的结构进行了表征。在结核分枝杆菌H37Rv的异烟
肼敏感性测定中,Muconin表现出较好的抑制活性。
