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。
