DNA/RNA Synthesis Inhibitor

TH287 hydrochloride is a potent and selective inhibitor of MTH1, with an IC₅₀ of 0.8 nM. TH287 hydrochloride is highly selective towards MTH1, with no relevant inhibition of MTH2, NUDT5, NUDT12, NUDT14, NUDT16, dCTPase, dUTPase and ITPA at 100 μM. TH287 hydrochloride could act as a chemotherapeutic agent for cancer research.

Gimeracil (Standard) is the analytical standard of Gimeracil. This product is intended for research and analytical applications. Gimeracil, a component of an oral fluoropyrimidine derivative S-1, inhibits DNA DSB repair and is a potent inhibitor of DPYD (dihydropyrimidine dehydrogenase, DPD).

R-1479 (Standard) is the analytical standard of R-1479 (HY-10444). This product is intended for research and analytical applications. R-1479 (4'-Azidocytidine), a nucleoside analogue, is a specific inhibitor of RNA-dependent RNA polymerase (RdRp) of HCV. R-1479 inhibits HCV replication in the HCV subgenomic replicon system (IC₅₀=1.28 μM). R-1479 is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

HAMNO (Standard) is the analytical standard of HAMNO (HY-111285). This product is intended for research and analytical applications. HAMNO is a novel protein interaction inhibitor of replication protein A (RPA).

Gemcitabine 5'-diphosphate (dFdCDP) is a core active metabolic intermediate of Gemcitabine (HY-17026) and a potent ribonucleotide reductase (RNR) inhibitor. Gemcitabine 5'-diphosphate depletes deoxyribonucleotide pools, consumes deoxycytidine triphosphate and increases the phosphorylation level of gemcitabine. Gemcitabine 5'-diphosphate prolongs the intracellular retention duration of gemcitabine metabolites, enhances the nucleic acid incorporation of gemcitabine, and exerts anti-tumor/cytotoxic effects.

MRL-436 is a RNA polymerase inhibitor with antibacterial activity. MRL-436 exerts its antibacterial activity dependent on residue 622 of the RNA polymerase β' subunit and the RNAP ω subunit. MRL-436 inhibits Rifampicin (HY-B0272)-resistant RNA polymerase derivatives and exhibits antibacterial activity against Rifampicin-resistant strains.

NSC 617145 (Standard) is the analytical standard of NSC 617145 (HY-110185). This product is intended for research and analytical applications. NSC 617145 is a selective werner syndrome helicase (WRN) helicase inhibitor with an IC₅₀ value of 230 nM. NSC 617145 inhibits WRN ATPase, and induces double-strand breaks (DSB) and chromosomal abnormalities. NSC 617145 shows selective for WRN over BLM, FANCJ, ChlR1, RecQ, and UvrD helicases.
