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.
