DNA/RNA Synthesis

Pyrazofurin, a pyrimidine nucleoside analogue with antineoplastic activity, inhibits cell proliferation and DNA synthesis in cells by inhibiting uridine 5'-phosphate (UMP) synthase[1]. Pyrazofurin is an active, sensitive orotate-phosphoribosyltransferase inhibitor with IC50s between 0.06-0.37 ?M in the three squamous cell carcinoma (SCC) cell lines Hep-2, HNSCC-14B and HNSCC-14C.

AOH1160 is a potent, first-in-class, orally available small molecule proliferating cell nuclear antigen (PCNA) inhibitor, interferes with DNA replication, blocks homologous recombination-mediated DNA repair, causes cell-cycle arrest and induces apoptosis.

Xanthopterin is a yellow, crystalline solid that inhibits the growth of lymphocytes produced by concanavalin.

JH-RE-06, a potent REV1-REV7 interface inhibitor (IC50=0.78 μM; Kd=0.42 μM), targets REV1 that interacts with the REV7 subunit of POLζ.

TH588 hydrochloride is first-in-class nudix hydrolase family inhibitor that potently and selectively engage and inhibit the MTH1 (IC50= 5 nM).

MB-7133 is a DNA synthesis inhibitor.

Enocitabine is a nucleoside analog, and is a potent DNA replication inhibitor, and a DNA chain terminator.
