Abstract

Inhibition of lactate dehydrogenase (LDH) represents an innovative approach to tackle cancer because this peculiar glycolytic metabolism is characteristic of most invasive tumor cells. An investigation into the biological properties of saffron extracts led to the discover of their LDH-inhibition properties. In particular, the most important saffron components, crocetin, was found to inhibit LDH (IC50 = 54.9 ± 4.7 μM). This carotenoid was independently produced by chemical synthesis, and its LDH-inhibition properties manifested via its antiproliferative activity against two glycolytic cancer cell lines (A549 and HeLa, IC50 = 114.0 ± 8.0 and 113.0 ± 11.1 μM, respectively). The results described in this article suggest that saffron may be a helpful alimentary component in the prevention of cancer that potentially contributes to the efficacy of approved cancer therapies.
