The experimental chemotherapeutic N6-furfuryladenosine (kinetin-riboside) induces rapid ATP depletion, genotoxic stress, and CDKN1A(p21) upregulation in human cancer cell lines.

ABSTRACT: Cytokinins and cytokinin nucleosides are purine derivatives with potential anticancer activity. N(6)-furfuryladenosine (FAdo, kinetin-riboside) displays anti-proliferative and apoptogenic activity against various human cancer cell lines, and FAdo has recently been shown to suppress tumor growth in murine xenograft models of human leukemia and melanoma. In this study, FAdo-induced genotoxicity, stress response gene expression, and cellular ATP depletion were examined as early molecular consequences of FAdo exposure in MiaPaCa-2 pancreas carcinoma, A375 melanoma, and other human cancer cell lines. FAdo, but not adenosine or N(6)-furfuryladenine (FA), displayed potent anti-proliferative activity that was also observed in human primary fibroblasts and keratinocytes. Remarkably, massive ATP dep
