Structure elucidation of a dihydropyranone from Tapinanthus dodoneifolius.
A new dihydropyranone, ( R)-6-[( S)-2-hydroxy-4-(4-hydroxyphenyl)butyl]-5,6-dihydropyran-2-one ( 1), was isolated from Tapinanthus dodoneifolius. The structure was determined from spectroscopic and X-ray crystallographic analysis. Compound 1 (named dodoneine) showed a relaxing effect on preconstricted rat aortic rings (IC 50 of 81.4 +/- 0.9 microM).
