Lanostane-type triterpenoids from Kadsura coccinea

Lanostane-type triterpenoids from Kadsura coccinea
Systematic phytochemical investigation on the stems of Kadsura coccinea resulted in the isolation of eleven new lanostane-type triterpenoids, named kadcoccinones G–Q (111), together with two known structural analogues, kadpolysperin M (12) and abiesatrine D (13). Their structures were characterized on the basis of comprehensive spectroscopic methods, and the absolute configuration of 1 was ascertained by single-crystal X-ray diffraction. Structurally, compounds 1/2, 4/5, and 6/7 were three pairs of C-12 epimers, respectively. Additionally, compounds 111 were evaluated for their in vitro cytotoxicity against the human tumor HL-60, SMMC-772, A-549, MCF-7, SW-480, and HeLa cell lines using the MTS viability assay.
