Investigated for use/treatment in leukemia (myeloid).
Troxacitabine is a beta-L-nucleoside analog, which has shown preclinical antitumor activity in human xenograft tumor models and antileukemic response in patients with relapsed myeloid leukemia.
Mechanism of action
Troxacitabine is activated by cellular kinases and incorporated into DNA, inhibiting its replication. In contrast to other cytosine nucleoside analogs, troxacitabine is resistant to inactivation by cytidine deaminase (CD).
Trastuzumab may increase the cardiotoxic activities of Troxacitabine.

This compound belongs to the class of chemical entities known as nucleoside and nucleotide analogues. These are analogues of nucleosides and nucleotides. These include phosphonated nucleosides, C-glycosylated nucleoside bases, analogues where the sugar unit is a pyranose, and carbocyclic nucleosides, among others.
Required for the phosphorylation of the deoxyribonucleosides deoxycytidine (dC), deoxyguanosine (dG) and deoxyadenosine (dA). Has broad substrate specificity, and does not display selectivity based on the chirality of the substrate. It is also an essential enzyme for the phosphorylation of numerous nucleoside analogs widely employed as antiviral and chemotherapeutic agents.
