Upon analyzing the structure-activity relationship, it was found that coumarin-based derivatives exerted cytotoxic and antitumor activity. In the present study a new ester of α-lipoic acid and derivative of alloxanthoxyletin (LAA) was synthesized and evaluated for its anticancer activity. The structure of this new compound was confirmed by {sup 1}H NMR, {sup 13}C NMR, and HRMS spectroscopic analyses. Both, the cytotoxicity and the migration tests showed that human melanoma cells (HTB-140) and human lung cancer cells (A549) were more sensitive to LAA exposure than human normal keratinocytes (HaCaT). Moreover, LAA induced significant HTB-140 and A549 apoptosis, as evidenced by V-FITC/7-AAD flow cytometry analysis. Preincubation of the HTB-140 and A549 cells with LAA increased a sensitivity of tumor cells to a drug-induced cell death. Significantly lower expression of IL-6 mRNA was observed in A549 and HTB-140 cells which were pre-incubated with LAA and then treated with doxorubicin as compared to the cells pre-incubated with LAA and then treated with cisplatin. The results suggest that the newly synthetized LAA is compound with anticancer activity promising for potential applications, but further studies are needed to gain more insight into the mechanism of action of tested derivative.
