The cytotoxicity of these compounds were valuated by MTT and SRB methods using three cancer cell lines: HL-60, A-549, P-388. Cyclo-shikonin, and cyclo-alkannin have high cytotoxicity against HL-60.The chiral center of side chain has no effect on their activity. 2- 1-(Acetyloxy-4-methyl-3-pentenyl -5, 8-dihydroxy-1, 4-naphthoquinone (105) has strong inhibition effect on P-388 cells. 2- 1-(isooctyloxy-4-methyl-3-pentenyl -5, 8-dihydroxy-1, 4-naphthoquinone (108) and 2- 1-(2-furoyloxy-4-methyl-3-pentenyl -5, 8-dihydroxy-1, 4-naphthoquinone (112) have high inhibition on A-549.Shikonin (1), alkannin (2), and their derivatives have the structural features of a planar chromophores and short side chain. We examined the ability to inhibit the telomerase.

抗肿瘤活性初步筛选测试采用小鼠白血病P-388肿瘤细胞和人肺癌A-549肿瘤细胞进行，结果表明侧链羟基的手性对抗肿瘤活性无明显影响；有数个化合物具有很好的体外抑制活性，特别是化合物2-（1-异辛酰氧基-4-甲基-3-戊烯基）-5，8-二羟基-1，4-萘醌（108）和2-[1-（2-呋喃甲酰氧基）-4-甲基-3-戊烯基]-5，8-二羟基-1，4-萘醌（112）体外显示对人肺癌A-549肿瘤细胞有强效；2-（1-乙酰氧基-4-甲基-3-戊烯基）-5，8-二羟基-1，4-萘醌（105）对小鼠白血病P-388肿瘤细胞有强效；环紫草素和环异紫草素对人白血病HL-60细胞有强烈抑制作用。

GFP gene eukaryotic express plasmids were transfected into ES cells. The cells were observed under the inverted fluorescent microscope. The clones which expressed the powerful green fluorescence were chosen to be named ES-GFP cells and cultured continuously. The examination of ES cell totipotent including Alkine phosphatase staining, embryonic body formation in vitro and teratomas formation in nude mice was implemented.
