Bioactive sesquiterpenoids from the flower buds of Tussilago farfara
Eleven new compounds including five bisabolane (1-5) and three oplopane (6-8) sesquiterpenoids, a pair of benzopyran enantiomers (9 & 10) and a benzofuran derivative (11), along with six known sesquiterpenoid cometabolites (12-17), have been obtained from the flower buds of Tussilago farfara. Their structures were elucidated by comprehensive spectroscopic analyses and comparison with structurally related known analogues. The absolute configurations of all the compounds except 11 were unequivocally assigned by various techniques, including Mosher’s method and time-dependent density functional theory (TD-DFT) based calculations of C-13 NMR and electronic circular dichroism (ECD) data. The C-8 absolute configuration on the sidechain of this group of bisabolane sesquiterpenoids was assigned for the first time. Our bioassays have established that compounds 3, 4, 13 and 14 showed significant alpha-glucosidase inhibitory activities, while 6, 8 and 14 displayed moderate antiproliferative effects against two human tumor cell lines A549 and MDA-MB-231. Further flow cytometric analysis revealed that 14 effectively induced cell apoptosis and arrested cell cycle at the S/G2 phases in A549 cells, in a dose-dependent manner.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 591-11-7, you can contact me at any time and look forward to more communication. HPLC of Formula: C5H6O2.
