  Cytotoxicity evaluation of natural coptisine and synthesis of coptisine from berberine

  摘要：

  The crude extract (80% MeOH in water) of Chelidonii herba exhibited very interesting cytotoxicity against brine shrimp (Artemia salina Leach) nauplii and cultured human tumour cell in vitro, the colon carcinoma HT 29 (144 h treatment). Fractionation of the crude extract and bioassay-guided procedures showed that the cytotoxic and,the antitumour activities. were concentrated in the basic extract. On the basis of IR, MS and H-1 NMR the compound responsible of the cytotoxic activity was determined to be coptisine. Cytotoxicity evaluation of-coptisine was next extended to-a panel of human and murine cell lines in comparison with the established antitumour drugs mitoxantrone, doxorubicin (D. x) and cisplatin. (CDDP). Coptisine was cytotoxic on LoVo and HT 29 and less potent on L-1210, and it was partially crossresistant on the human tumour colon cell line resistant to Dx, LoVo/Dx, whereas it was not significantly crossresistant on the murine leukaemia cell line resistant to. CD. DP, L-1210/CDDP. Coptisine alkaloid was then synthesised in gram amount from commercial berberine. A four-step synthetic route was elaborated. The overall yield was about 8-10%. The structural identity of synthetic coptisine was verified by IR and NMR methods. A comparison of the cytotoxic effects on the human tumour colon cell line LoVo and on the murine leukaemia L1210 showed, for both natural and synthetic coptisines, a comparable cytotoxic activity more evident against-HT 29 cell line and LoVo. cell line, while the activity was lower against the L1210 cell line.

  Two new alkaloids, corydamine hydrochloride, C20H19O4N2Cl, mp235-239° (decomp.) and N-formyl corydamine, C21H18O4N2, mp159.5-160.5°, were isolated from Corydalis incisa PERS. (Papaveraceae) and their structures were established to be II and IX, respectively, by spectroscopic analyses and their chemical conversion to coptisine iodide and anhydrodihydroprotopine-B. Corydamine hydrochloride and N-formyl corydamine are noted as the first naturally occurring alkaloids having the 3-phenyl isoquinoline skeleton.

  从Corydalis incisa PERS.（罂粟科）中分离出了两种新的生物碱，氯化可瑞达明（corydamine hydrochloride），C20H19O4N2Cl，熔点235-239°（分解）和N-甲酰可瑞达明（N-formyl corydamine），C21H18O4N2，熔点159.5-160.5°。通过光谱分析及其与可尔托辛碘化物和无水二氢原花青素-B的化学转化，确定了它们的结构分别为II和IX。氯化可瑞达明和N-甲酰可瑞达明被认为是首批具有3-苯基异喹啉骨架的天然生物碱。
