ABSTRACT
Three undescribed aporphine alkaloids laurodionine B (1), illigerine A (2), and N-formyl-laurolitsine (3) were isolated from the methanolic extracts of the Chinese medicinal plant, Illigera aromatica, together with three known analogues (4-6). The chemical structures of 1-6 were identified by spectroscopic methods including 1D and 2D NMR (1H, 13C, COSY, HSQC, and HMBC) and high resolution mass spectrometry (HRESIMS). Compounds 1-3 showed moderate inhibitory activities in vitro against two cultured tumor cell lines, Hela and SMMC7721, with IC50 values of 32.42-62.90⯵M. Only compound 1 had in vitro cytotoxic activity against Bcap37â¯cells, with the IC50 value of 90.61⯵M.

Aporphine alkaloids, characterized by a heterocyclic aromatic basic skeleton, are known from different organisms and exhibit various biological activities: anti-tumor, anti-viral, anti-microbial, anti-inflammatory etc. The review gives information which provides an overview of the latest progress in the structural diversity and the biological activity of the aporphine alkaloids with their derivatives isolated from natural resource in recent years. Additionally, the synthetic approaches of aporphine alkaloids have also been reviewed.
