Nucleotide Compound Library

564 compounds

Nucleoside and nucleotide analogues are synthetic, chemically modified compounds that have been developed to mimic their physiological counterparts in order to exploit cellular metabolism and subsequently be incorporated into DNA and RNA to inhibit cellular division and viral replication. In addition to their incorporation into nucleic acids, nucleoside and nucleotide analogues can interact with and inhibit essential enzymes such as human and viral polymerases (that is, DNA-dependent DNA polymerases, RNA-dependent DNA polymerases or RNA-dependent RNA polymerases), kinases, ribonucleotide reductase, DNA methyltransferases, purine and pyrimidine nucleoside phosphorylase and thymidylate synthase. These actions of nucleoside and nucleotide analogues have potential therapeutic benefits — for example, in the inhibition of cancer cell growth, the inhibition of viral replication as well as other indications.

MCE offers a unique collection of 564 nucleotide compounds including nucleotide, nucleoside and their structural analogues. MCE Nucleotide Compound Library is a useful tool to discover anti-cancer and antiviral drugs for high throughput screening (HTS) and high content screening (HCS).

Baloxavir-d4

Baloxavir-d₄ (Baloxavir acid-d₄; S-033447-d₄) is the deuterium-labeled Baloxavir (HY-109025A). Baloxavir-d₄ (Baloxavir-d₄ acid), derived from the proagent Baloxavir-d₄ marboxil, is a first-in-class, potent and selective cap-dependent endonuclease (CEN) inhibitor within the polymerase PA subunit of influenza A and B viruses. Baloxavir-d₄ inhibits viral RNA transcription and replication and has potently antiviral activity .

Favipiravir-13C3
Favipiravir- ¹³C3 is the ¹³C labeled isotope of Favipiravir- ¹³C3(HY-14768 ).Favipiravir (T-705) is a potent viral RNA polymerase inhibitor, it is phosphoribosylated by cellular enzymes to its active form, Favipiravir-ribofuranosyl-5′-triphosphate (RTP). Favipiravir-RTP inhibits the influenza viral RNA-dependent RNA polymerase (RdRP) activity with an IC₅₀ of 341 nM.

HY-14768S

Favipiravir-13C15N

Favipiravir- ¹³C ¹⁵N (T-705- ¹³C ¹⁵N) is ¹³C and ¹⁵N labeled Favipiravir. Favipiravir (T-705) is a potent viral RNA polymerase inhibitor, it is phosphoribosylated by cellular enzymes to its active form, Favipiravir-ribofuranosyl-5′-triphosphate (RTP). Favipiravir-RTP inhibits the influenza viral RNA-dependent RNA polymerase (RdRP) activity with an IC₅₀ of 341 nM.

2'-Deoxy-2'-fluorouridine-d2

2'-Deoxy-2'-fluorouridine-d₂ is the deuterium labeled 2'-Deoxy-2'-fluorouridine . 2'-Deoxy-2'-fluorouridine is a derivative of the pyrimidine nucleoside uridine. 2'-Deoxy-2'-fluorouridine is a nucleoside analog that inhibits the replication of wild-type viruses by binding to the viral RNA. Hepatitis C polyU/UC RNA strands containing 2'-Deoxy-2'-fluorouridine, bind to RIG-I but do not activate RIG-I signaling in a reporter assay using Huh7 cells. 2'-Deoxy-2'-fluorouridine also has been used as a starting material in the synthesis of respiratory syncytial virus (RSV) polymerase inhibitors. 2'-Deoxy-2'-fluorouridine can incorporate into DNA and RNA in rat and woodchuck model upon administration. 2'-Deoxy-2'-fluorouridine can be studied in anti-viral research .
