3-Deazauridine (DAU, NSC 126849) is a nucleoside analog that competitively inhibits cytidine triphosphate synthetase (CTP).3-Deazauridine inhibits the growth of L1210 leukemia cells when used at a concentration of 6 µM and dose-dependently reduces mortality in a mouse model of leukemia.3-Deazauridine selectively suppresses cell viability in a MYC-dependent manner in ARPE-19 cells.3-Deazauridine causes selective replication stress in MYC-overexpressing cells, which originates from MYC-driven rRNA synthesis.3-Deazauridine combined with ATR inhibitor BAY-1895344 induces synthetic lethality to MYC-overexpressing cells, and suppresses tumor growth in 3D assays and in vivo.
Fludarabine triphosphate (F-ara-ATP) trisodium, the active metabolite of Fludarabine, is a potent, noncompetitive and specific inhibitor of DNA primase, with an IC50 of 2.3 μM and a Ki of 6.1 μM. Fludarabine triphosphate trisodium inhibits DNA synthesis by blocking DNA primase and primer RNA formation. Fludarabine triphosphate trisodium inhibits ribonucleotide reductase and DNA polymerase and ultimately leads to cellular apoptosis.
Fludarabine triphosphate (F-ara-ATP), the cytotoxic metabolite of Fludarabine phosphate, inhibits ribonucleotide reductase and DNA polymerase and ultimately leads to cellular apoptosis.
Ribavirin 5'-monophosphate dilithium is an active form of ribavirin that inhibits IMP dehydrogenase, and ribavirin itself is a broad-spectrum antiviral agent.
Pseudouridine 5'-OTBDPS (5-(5-O-TBDPS-β-D-ribofuranosyl)uracil) is an intermediate of Pseudouridine. PROTACs are inducers of ubiquitination-mediated degradation of cancer-promoting proteins.
