Biological activity of 1-deazapurine nucleosides: role of deoxycytidine kinase?
Several 1-deazapurine nucleosides were tested for their biological activity, anti-HIV-1, cytotoxicity and inhibition of adenosine deaminase (ADA). A2780 human ovarian cancer cells and the deoxycytidine kinase (dCK) deficient variant AG6000, used to determine whether dCK plays a role in their activation, showed a similar sensitivity to the analogs. This is in line with substrate specificity tests, which revealed a very low affinity of dCK.
