Besides, the series of synthetic compounds were tested for their capability to suppress growth of human hepatocellular carcinoma cell line Hep 3B and Hep G2, and myeloid leukemia cell line HL-60. The results showed compound 20, N-(2-amino- 3-nitrophenyl)cantharidinimide, exhibited more potent than others, but it was still less effective than cantharidin.

此外也利用斑蝥胺的衍生物对人类肝癌细胞Hep 3B和Hep G2，以及血癌细胞HL-60的细胞毒性进行测试，结果显示化合物20 [N-(2-amino-3-nitrophenyl)cantharidinimide]有较好的抑制作用，但是效果仍未比斑蝥素好。

Liaoning Medical University, Jinzhou 121001 China）Abstract:Objective To study the distribution and liver targeting of glycyrrhetinic acid derivatives (stearin glycyrrhetinic acid ester-3-O-galactosidase, Gal-GAOSt) modifying norcantharidin liposomes (Gal-GAOStNC-LP) in rats.
