3-Deazauridine 是一种尿苷的结构类似物，通过竞争性抑制胞苷三磷酸合成酶来抑制胞苷-5'-三磷酸的生物合成，这种合成酶被认为是这种核苷类似物的主要作用方式。

3-Deazauridine is a structural analog of uridine that inhibits the biosynthesis of Cytidine-5'-Triphosphate by competitive inhibition of Cytidine Triphosphate synthetase which is considered to be the primary mode of action of this nucleoside analog.

3-Deazauridine enhanced the in vitro antineoplastic action of 5-AZA-CdR on human leukemic cells by increasing its incorporation into DNA. Using an optimized dose-schedule we showed that this combination could cure some mice bearing L1210 leukemia, even in the presence of a subpopulation of drug-resistant (L1210/ARA-C) leukemic cells lacking DCK. 3-Deazauridine alone also cured some mice with L1210/ARA-C leukemia[1].
