Two new morphinane alkaloids from Sinomenium acutum
XL Wang, BR Liu, JR Wang, CK Chen… - Journal of Asian …, 2011 - Taylor & Francis
Two new morphinane alkaloids, 1-hydroxy-10-oxo-sinomenine (1) and 4, 5-epoxy-14-
hydroxy sinomenine N-oxide (2), have been isolated from the stems of Sinomenium acutum.
Their structures were established by various spectral analyses, especially 2D NMR
experiments. The structure of 2 was confirmed by single crystal X-ray diffraction. The
absolute configurations of 1 and 2 were deduced by comparison of CD spectra with the
known alkaloid sinomenine (3). Compound 1 was tested for DPPH inhibition and gave IC50 …
