Micranoic acids A and B: two new octanortriterpenoids from Schisandra micrantha.
Two novel octanortriterpenoids, micranoic acids A (1) and B (2), along with three known compounds, kadsuric acid (3), 3beta-hydroxy-lanost-9(11),24(25)-dien-26-oic acid (4) and schizandronic acid (5), were isolated from the leaves and stems of Schisandra micrantha. The structures of 1 and 2 were determined by 1D and 2D NMR spectroscopic analysis. Micranoic acids A and B represent a new group of...
متن کاملNeglschisandrins A-B: two new dibenzocyclooctene lignans from Schisandra neglecta.
Two new dibenzocyclooctene lignans, neglschisandrins A-B (1-2), were isolated from the stems of Schisandra neglecta. Their structures and stereochemistries were elucidated by spectroscopic methods, including 1D- and 2D-NMR and HR-ESI-MS techniques.
متن کاملStructure and anti-HIV activity of micrandilactones B and C, new nortriterpenoids possessing a unique skeleton from Schisandra micrantha.
Two new highly oxygenated nortriterpenoids with a unique norcycloartane skeleton, micrandilactones B and C, were isolated from Schisandra micrantha; micrandilactone C exhibited an EC50 value of 7.71 microg/mL (SI > 25.94) against HIV-1 replication with minimal cytotoxicity, and the potent anti-HIV-1 activity and unique structural features of make it a promising lead for therapeutic development ...
متن کاملTwo new lignans from Schisandra henryi.
Two new lignans, henricines A (1) and B (2), were isolated along with the eight known lignans, ganshisandrine (3), wulignan A(2) (4), epiwulignan A(1) (5), deoxyschisandrin (6), wulignan A(1) (7), epischisandrone (8), schisantherin A (9), and schisandrol A (10), from the stems of Schisandra henryi. The structures of the new compounds were elucidated based on the spectral analysis, including 1D ...
