Two sulfonated diterpenoid alkaloids with novel carbon skeletons, named aconidenusulfonine A (1) and 12,16-secoaconidenusulfonine A (2), were isolated from the roots of Aconitum carmichaelii (Fu Zi). The structures of 1 and 2 were determined through spectroscopic analysis and chemical transformation, and the structure of 1 was further confirmed by single-crystal X-ray diffraction. Moreover, compound 1 exhibited dose-dependent analgesic activity.
Two sulfonated diterpenoid alkaloids possessing different but related novel carbon skeletons, named aconidenusulfonine A (1) and 12,16-secoaconidenusulfonine A (2), respectively, were isolated as minor components from an aqueous extract of the lateral roots of Aconitum carmichaelii (Fu Zi). The structures of 1 and 2, representing the first two C-21-diterpenoid alkaloids from nature, were determined by analysis of various spectroscopic data and chemical transformation, of which 1 was further proved by single-crystal X-ray diffraction. Especially, 1 exhibited dose-depended analgesic activity consistent with the clinical function of Fu Zi.
