γ-Glu-Cys is an intermediate in glutathione (GSH) synthesis.1It is formed by ATP-dependent condensation of cysteine and glutamate by γ-glutamylcysteine synthetase. γ-Glu-Cys is also an essential component of phytochelatins, the heavy metal detoxifying enzymes in plants.2

6-Hydroxypyridin-3-ylboronic acid is a heterocyclic building block.1,2It has been used in the synthesis of non-nucleoside inhibitors of hepatitis C virus (HCV) RNA-dependent RNA polymerase nonstructural protein 5B (NS5B).16-Hydroxypyridin-3-ylboronic acid has also been used in the synthesis of mammalian target of rapamycin (mTOR) inhibitors.2 1.Hendricks, R.T., Spencer, S.R., Blake, J.F., et al.3-Hydroxyisoquinolines as inhibitors of HCV NS5b RNA-dependent RNA polymeraseBioorg.

2'-Deoxyguanosine 5'-monophosphate (dGMP) is used as a substrate of guanylate kinases to generate dGDP, which in turn is phosphorylated to dGTP, a nucleotide precursor used in DNA synthesis. In addition, dGMP can be efficiently phosphorylated by the type I thymidylate kinase of the malarial agent P. falciparum. In humans, deficiency of mitochondrial deoxyguanosine kinase, which synthesizes dGMP from ATP and deoxyguanosine, contributes to mitochondrial DNA depletion syndrome.

2,6-Dichloropurine-9-β-D-riboside is a building block.1,2It has been used in the synthesis of photoaffinity probes for nucleotide binding sites in proteins. 1.Wower, J., Hixson, S.S., Sylvers, L.A., et al.Synthesis of 2,6-diazido-9-(β-D-ribofuranosyl)purine 3',5'-bisphosphate: Incorporation into transfer RNA and photochemical labeling of Escherichia coli ribosomesBioconjug.

Pantothenate Kinase Inhibitor (PANKi) is a reversible inhibitor of pantothenate kinase (PanK; IC50s = 70, 92, and 25 nM for PanK1β, PanK2, and PanK3, respectively), the rate-limiting enzyme in the synthesis of coenzyme A .1It binds to the ATP-PanK3 complex with an apparent binding constant of 300 nM and exhibits mixed-type inhibition with respect to ATP and pantothenate. PANKi inhibits CoA biosynthesis in C3A cells (IC50= 0.9 μM) with no effect on cell viability when used at concentrations up to 8 μM. PANKi (5 μM) synergizes with BSO to induce ferroptosis in PANC-1 cells and sensitizes the cells to imidazole ketone erastin-induced ferroptosis.2 1.Sharma, L.K., Leonardi, R., Lin, W., et al.A high-throughput screen reveals new small-molecule activators and inhibitors of pantothenate kinasesJ.

Thymidine 5′-diphosphate (dTDP), a crucial product of pyrimidine synthesis in organisms, is synthesized through the thymidylate kinase (TMPK)-catalyzed phosphorylation of 5′-thymidine monophosphate (dTMP), requiring ATP and Mg2+. It is further converted to thymidine 5′-triphosphate (dTTP) via TMPK catalysis. The activity of TMPK can be monitored by assessing the levels of dTDP [1] [2].

ATP Synthase Inhibitor 2 (Compound 22) TFA is a potent inhibitor of Pseudomonas aeruginosa ATP synthase with an IC50 value of 10 μg mL. It effectively halts ATP synthesis in Pseudomonas aeruginosa at a concentration of 128 μg mL [1].

6-Chloropurine riboside-5'-triphosphate serves as both an inhibitor and an activator in biochemical processes. It inhibits the RNA triphosphatase mRNA-capping enzyme subunit β (Cet1; IC50 = 2 µM for the GTPase activity of the S. cerevisiae enzyme), proving its efficacy against the enzyme responsible for the capping of mRNA molecules. Additionally, it acts as a phosphorylated derivative of 6-chloropurine riboside. This compound also activates the E. coli enzyme aspartate carbamoyltransferase (EC50 = 0.76 mM), demonstrating its versatility in modulating enzyme activities. It is instrumental in the synthesis of cytokinins with anticancer properties and a photoclickable form of ATP, highlighting its applications in biochemical synthesis and potential therapeutic uses.

Adenine-2-d1 is a deuterated compound of Adenine. Adenine has a CAS number of 73-24-5. Adenine, a purine derivative, is a nucleobase with various roles in biochemistry including cellular respiration, in the form of both the energy-rich ATP and NAD and FAD, and protein synthesis, as a chemical component of DNA and RNA.

2-Amino-ATP sodium solution (100mM) is a labeled and modified deoxyribonucleotide (dNTP) capable of releasing pyrophosphate to produce fluorescence, which has specific applications in gene synthesis and sequencing.
