Title: Triterpenoids from Schisandra lancifolia with anti-HIV-1 activity. Author: Xiao WL, Tian RR, Pu JX, Li X, Wu L, Lu Y, Li SH, Li RT, Zheng YT, Zheng QT, Sun HD. Journal: J Nat Prod; 2006 Feb; 69(2):277-9. PubMed ID: 16499331. Abstract: A new trinorcycloartane triterpenoid, lancifodilactone H (1), and a new A ring-secocycloartane triterpenoid, lancifoic acid A (2), together with a known compound, nigranoic acid (3), were isolated from the leaves and stems of Schisandra lancifolia. Their structures were elucidated by spectroscopic data analysis. Compound 1 features a biosynthetically modified seven-membered lactone ring, which was confirmed by single-crystal X-ray diffraction. Compounds 1-3 exhibited weak anti-HIV-1 activity in vitro.[Abstract] [Full Text] [Related] [New Search]
