NCIt definition : An orally bioavailable, nucleoside analog and DNA methyltransferase I (DNMT1) inhibitor,
with potential DNA hypomethylating and antineoplastic activities. Upon administration,
5-aza-4'-thio-2'-deoxycytidine (Aza-TdC) gets incorporated into DNA, where it binds
to the active site of DNMT1, a maintenance methyltransferase that contributes to the
hypermethylation and silencing of tumor suppressor genes. The formation of covalent
DNMT1-DNA complexes inhibits DNMT1, prevents DNA methylation of CpG sites, causes
CpG demethylation, and results in the re-expression and re-activation of silenced
tumor suppressor genes. This inhibits tumor cell proliferation. DNMT1, overactivated
in tumor cells, plays a key role in tumor cell proliferation.;
