Relative stereochemistry of a diterpene from Salvia cinnabarina.
The relative stereochemistry of 3,4-secoisopimara-4(18),7,15-triene-3-oic acid, a diterpenoid with antispasmodic, hypotensive and antibacterial activities isolated from Salvia cinnabarina, was determined by an X-ray diffraction analysis of a single crystal of a suitable crystalline derivative.
متن کاملIsolation and relative stereochemistry of lippialactone, a new antimalarial compound from Lippia javanica.
The aerial parts of Lippia javanica were investigated for biologically active chemical compounds present in them. Chromatographic separation of the ethyl acetate extract of the aerial parts yielded a new antimalarial α-pyrone, lippialactone (2). Lippialactone is active against the chloroquine-sensitive D10 strain of Plasmodium falciparum with an IC50 value of 9.1 μg/mL, and is also mildly cytot...

متن کاملLabdane-Type Diterpene and Two Flavones from Salvia Sharifii Rech. f. and Esfan. and their Biological Activities
Two flavones, ladanein and 6-hydroxy-5,7,4′-trimethoxyflavone and one labdane-typediterpene, ent-13-epi-manoyloxide, were isolated from an ethyl acetate-methanol extract ofthe aerial parts of Salvia sharifii. The compounds were purified using several chromatographicmethods. Structural elucidation of the compounds was performed using their 1H and 13C-NMRdata, EI mass and UV spectral data. The co...
