Product Description
Censavudine (OBP-601; BMS-986001), a nucleoside analog, is a nucleoside reverse transcriptase inhibitor. Censavudine is a potent HIV inhibitor (antagonist) with EC50 ranges of 30-81 nM and 450-890 nM for HIV-2 and HIV-1, respectively. Censavudine is a click chemistry agent. It has Alkyne groups and could undergo CuAAc (copper-catalyzed azide-alkyne cycloaddition reaction) with compounds bearing Azide groups.
Censavudine (CAS: 634907-30-5) is a nucleoside reverse transcriptase inhibitor (NRTI) that is active against HIV. It is also known as 2',3'-didehydro-3'-deoxy-4'-ethynylthymidine (4'-Ed4T). Censavudine is a nucleoside analog that was developed as an antiviral drug for the treatment of HIV/AIDS. It is active against HIV resistant to both abacavir and tenofovir, making it a candidate for people with multi-drug resistant (MDR) strains of the virus.
Biological Activity I Assay Protocols (From Reference)
Targets
The primary target of Censavudine is the HIV reverse transcriptase enzyme, which is essential for the replication of the HIV virus. As a nucleoside reverse transcriptase inhibitor (NRTI), Censavudine is a nucleoside analog that is incorporated into the growing viral DNA chain during reverse transcription. This incorporation terminates DNA chain elongation, thereby blocking viral replication. Censavudine is active against HIV-1 and HIV-2 and is effective against HIV strains resistant to abacavir and tenofovir.
ln Vitro
In single-cycle experiments, BMS-986001's average EC50 was 74 nM for HIV-2ROD9 and 890 nM for HIV-1NL4-3, indicating that it is more potent against HIV-2ROD9 than HIV-1NL4-3. In a 4-day infection of immortalized T cell lines (CEMss), HIV-2ROD9 also shown increased sensitivity to BMS-986001; the average EC50 of HIV-2ROD9 (EC50 of 0.14 nM) was 30-fold lower than that of HIV 1NL4-3 (EC50 of 4.2 nM) [1]. BMS-986001 demonstrates complete efficacy against HIV-2 strains that have single amino acid alterations encoded in their reverse transcriptases, K65R and Q151M [1].
Censavudine demonstrates in vitro antiviral activity against HIV-1 and HIV-2. It is active against HIV strains resistant to both abacavir and tenofovir. However, detailed IC50 or EC50 values for antiviral activity are not extensively reported in the available literature. The compound's mechanism of action as an NRTI is well-established based on its structural similarity to other nucleoside analogs.
ln Vivo
Pharmacokinetic characteristics of sensavudine (BMS-986001; 100-750 mg/kg) derived from dried blood spot (DBS) assays and plasma assays were compared. Across all dose groups in rats, the AUC(0-24 h) and C max of BMS-986001 in DBS were consistent with the ratios in plasma, 0.83-0.91 and 0.81-0.97, respectively. The T max in rat DBS and plasma is also constant at roughly 1 hour [2].
Censavudine has been used in trials studying the treatment of HIV-1 infection. It is a candidate for people with multi-drug resistant (MDR) strains of the virus. However, specific in vivo efficacy data, including clinical trial results, are not extensively detailed in the available literature. The compound has been evaluated in clinical trials for HIV treatment.
Enzyme Assay
In vitro enzyme assays for Censavudine typically involve measuring its inhibition of HIV reverse transcriptase activity. Recombinant HIV reverse transcriptase enzyme is incubated with a template-primer and nucleotide substrates in the presence of varying concentrations of Censavudine. The incorporation of radiolabeled nucleotides into the growing DNA strand is measured to determine the enzyme activity. The IC50 for inhibition is calculated from the dose-response curve.
Cell Assay
Cellular assays for Censavudine are performed in HIV-susceptible cell lines, such as MT-4 or CEM cells. Cells are infected with HIV-1 or HIV-2 and treated with various concentrations of Censavudine. After several days of culture, viral replication is measured by quantifying viral antigens (e.g., p24 for HIV-1) in the culture supernatant or by assessing the cytopathic effect of the virus on the cells. The compound's antiviral activity is expressed as the EC50.
Animal Protocol
In vivo animal studies with Censavudine are not extensively documented in the available literature. As an NRTI developed for HIV treatment, the compound would have been evaluated in animal models of HIV infection, such as humanized mouse models or non-human primate models. However, specific protocols and results are not detailed in the available sources. The compound has been evaluated in clinical trials.
ADME/Pharmacokinetics
Censavudine has a molecular weight of 248.23 and a molecular formula of C12H12N2O4. It is a nucleoside analog that is soluble in DMSO and other organic solvents. The compound is stable when stored at -20°C. However, detailed pharmacokinetic parameters such as absorption, distribution, metabolism, excretion, half-life, and bioavailability are not extensively reported in the available literature.
Toxicity/Toxicokinetics
Comprehensive toxicology data for Censavudine are not extensively reported. As a compound that has been evaluated in clinical trials, it would have undergone toxicological evaluation, but specific data are not detailed in the available literature. The compound is classified as a research-use-only chemical and is not intended for human consumption.
