Metal Dithiocarbamates

From a study of the isotropic proton hyperfine interaction constants for a series of metal dithiocarbamates, and their redox behaviour, it is shown that for iron(111) and manganese(111) dithiocarbamates there is a simple relationship between E1/2 and the NCH2 proton hyperfine interaction constant in the 6Al state. Hence the redox process for these compounds is inferred to take place through the nitrogen atom.

Acorus Tatarinowii

A new brominated norsesquiterpene glycoside, acoruside (1), has been isolated from the rhizomes of Acorus tatarinowii Schott, together with 8 known compounds (2-9). Their structures were elucidated mainly based on 1-dimensional (1D) and 2D nuclear magnetic resonance spectra. The absolute configuration of compound 1 was determined by comparing its experimental and calculated electronic circular dichroism spectra. The in vitro tests indicated that at 10 µM, compounds 2, 3, and 4 aggravated serum deprivation injuries of PC12 cells, compound 2 aggravated rotenone-induced injuries of PC12 cells, and compounds 3 and 4 aggravated the oxygen-glucose deprivation-induced injuries of PC12 cells.
