ddhCTP
Based on 1 publication(s) in Google Scholar
ddhCTP is an endogenously produced pyrimidine base analog with a Kd of 17.0 nM for LLDH and an IC50 of 55.8 μM for GAPDH. By inhibiting key metabolic enzymes such as GAPDH, ddhCTP reduces glycolytic flux and shifts metabolic flow toward the pentose phosphate pathway, thereby regulating the redox balance of cells. As a competitive CTP analog, ddhCTP terminates RNA synthesis by flavivirus RdRps and SARS-CoV-2 RdRp, and inhibits Zika virus replication in vivo. ddhCTP can be used in studies related to viral infections, COVID-19 and Zika virus infections.

Biological Activity
ddhCTP (24-96 h) completely abolishes the extracellular levels of phenylacetic acid and 4-hydroxyphenyllactic acid in HEK293 cells expressing wild-type RSAD2[1].
ddhCTP (72 h) modulates the levels of NAD+-dependent enzyme-related metabolites, including decreased taurine levels, increased 2-oxoglutarate levels, increased glyceraldehyde 3-phosphate levels, and increased levels of pentose phosphate pathway intermediates in hiPSC-derived macrophages expressing wild-type RSAD2 after stimulation with LPS and IFN-γ[1].
ddhCTP inhibits the NAD+-dependent forward activity of purified rabbit muscle GAPDH with an IC50 of 55.8 μM, but does not affect the NADH-dependent reverse reaction[1].
ddhCTP (72 μM, 30 s) inhibits the NAD+-dependent activities of purified rabbit muscle LLDH and purified bovine heart MDH, but does not affect the NADH-dependent reverse reaction of LLDH[1].
