Synthesis and Evaluation of Artemisinin-Based Hybrid and Dimer Derivatives as Antimelanoma Agents

A library of hybrid and dimer compounds based on the natural scaffold of artemisinin was synthesized. These
\nderivatives were obtained by coupling of artemisinin derivatives, artesunate, and dihydroartemisinin with a panel of
\nphytochemical compounds. The novel artemisinin-based hybrids and dimers were evaluated for their anticancer activity on a cervical cancer cell line (HeLa) and on three complementary metastatic melanoma cancer cell lines (SK-MEL3, SK-MEL24, and RPMI-7951). Two hybrid compounds obtained by coupling of artesunate with eugenol and tyrosol, and one of the dimer compounds containing curcumin, emerged as the most active and cancer-selective derivatives.
