Background: Ester and amide derivatives of shikonin were synthesized to improve the chemical stability of shikonin.
Methods: All synthesized compounds were evaluated for their antiproliferative activity against A549 cell line by SRB assay, and five of them demonstrated comparable cytotoxicity to shikonin.
Results and Conclusion: The most potent compound, 22d, was more stable and potent than shikonin.
