Project supported by the Applied Technology Research and Development and Demonstration Project of Hainan Province (No. ZDXM2015063), the National Natural Science Foundation of China (Nos. 21662011 and 31660097) and the Program for Innovative Research Team in University (No. IRT-16R19).
A new indole alkaloid, nauclofficine (1), together with three known alkaloids, naucleamide A (2), naucleamide D (3) and latifoliamide A (4), were isolated from the stems and leaves of Nauclea officinalis. Their structures were established on the basis of extensive spectral analyses. All known compounds were isolated from N. officinalis for the first time. The cytotoxicities of compounds 1~4 were evaluated against five cancer cell lines (HL-60, A549, SMMC-7721, MCF-7 and SW480). Research results showed that compounds 1~4 exhibited significant inhibitory effects with IC50 values comparable to those of cisplatin.
Key words: Nauclea; Nauclea officinalis; nauclofficine; cytotoxicities
