Forodesine Quick inquiry Where to buy Suppliers range | Forodesine, also known as BCX-1777, is the hydrochloride salt of the synthetic high-affinity transition-state analogue forodesine. Forodesine binds preferentially to and inhibits purine nucleotide phosphorylase (PNP), resulting in the accumulation of deoxyguanosine triphosphate and the subsequent inhibition of the enzyme ribonucleoside diphosphate reductase and DNA synthesis. This agent selectively causes apoptosis in stimulated or malignant T-lymphocytes. A transition state analogue is a substrate designed to mimic the properties or the geometry of the transition state of reaction. Synonyms: Immucillin-H hydrochloride; Forodesine. Grades: 98%. CAS No. 209799-67-7. Molecular formula: C11H14N4O4. Mole weight: 266.25. | |

Gemcitabine Hydrochloride (2-Deoxy-2,2-difluorocytidine Hydrochloride, dFdC, dFdCyd) Quick inquiry Where to buy Suppliers range | Gemcitabine is a nucleoside analog of deoxycytidine used as chemotherapy to treat patients with various types of cancer. After passage through the cell membrane via nucleoside transporters, gemcitabine undergoes complex intracellular conversion to gemcitabine diphosphate (dFdCDP) and triphosphate (dFdCTP). dFdCTP inhibits DNA polymerase by competing with deoxycytidine triphosphate (dCTP). dFdCDP inhibits ribonucleoside reductase and DNA synthesis by causing depletion of deoxyribonucleotide pools, and thus potentiating the effects of dFdCTP. Gemcitabine can be inactivated to 2,2'-difluorodeoxyuridine, mainly by deoxycytidine deaminase. Also, 5'-nucleotidase catalyses the conversion of nucleotides to nucleosides and inhibits nucleoside kinases. Group: Biochemicals. Alternative Names: 2-Deoxy-2,2-difluorocytidine Hydrochloride, dFdC, dFdCyd. Grades: Highly Purified. CAS No. 122111-03-9. Pack Sizes: 100mg, 500mg, 1g. US Biological Life Sciences. | Worldwide |
Guanosine 5'-Pyrophosphate Ester 6-Deoxytalose (>90%) Disodium Salt Quick inquiry Where to buy Suppliers range | Guanosine 5'-Pyrophosphate Ester 6-Deoxytalose has been used to study guanosine diphosphate-4-keto-D-rhamnose reductase enzyme catalysis.

Molecular formula: C16H23N5Na2O15P2. Mole weight: 633.31. | |
N-Hydroxyurea Quick inquiry Where to buy Suppliers range | Hydroxyurea is an antineoplastic agent that inhibits DNA synthesis through the inhibition of ribonucleoside diphosphate reductase. Uses: Antineoplastic agents; antisickling agents; enzyme inhibitors; nucleic acid synthesis inhibitors. Synonyms: NSC-32065; Hydroxycarbamide; Hydrea; 1-Hydroxyurea; Oxyurea; Biosupressin; Carbamohydroxamic acid; Litalir; N-Carbamoylhydroxylamine; Droxia; Siklos; Carbamoyl Oxime; Cytodrox; Hidrix.

RX-3117 Quick inquiry Where to buy Suppliers range | RX-3117, also known as TV-1360 and fluorocyclopentenylcytosine, is an orally available and potent DNA synthesis inhibitor with potential antineoplastic activity. Upon administration, the cytidine analogue RX-3117 is taken up by cells through a carrier-mediated transporter, phosphorylated by uridine cytidine kinase (UCK) and then further phosphorylated to its diphosphate (RX-DP) and triphosphate forms (RX-TP). The triphosphate form is incorporated into RNA and inhibits RNA synthesis. The diphosphate RX-DP is reduced by ribonucleotide reductase (RR) to dRX-DP; its triphosphate form (dRX-TP) is incorporated into DNA. In addition, RX-3117 also inhibits DNA methyltransferase 1 (DNMT1). This eventually leads to cell cycle arrest and the induction of apoptosis. UCK is the rate-limiting enzyme in the pyrimidine-nucleotide salvage pathway. Synonyms: RX3117; RX 3117; TV-1360; TV1360; TV 1360; fluorocyclopentenylcytosine. Grades: >98%. CAS No. 865838-26-2. Molecular formula: C10H12FN3O4. Mole weight: 257.221. | |
Tezacitabine Quick inquiry Where to buy Suppliers range | Tezacitabine is a synthetic purine nucleoside analogue with potential antineoplastic activity. Phosphorylated by cellular kinases, tezacitabine is converted into its active diphosphate and triphosphate metabolites. Tezacitabine diphosphate binds to and irreversibly inhibits the activity of the enzyme ribonucleotide reductase (RNR), which may result in the inhibition of DNA synthesis in tumor cells and tumor cell apoptosis. Tezacitabine triphosphate acts as a substrate for DNA polymerase, further compromising DNA replication. This agent is relatively resistant to metabolic deactivation by cytidine deaminase. RNR catalyzes the conversion of ribonucleoside 5'-diphosphates to deoxyribonucleoside 5'-diphosphates necessary for DNA synthesis and is overexpressed in many tumor types. Uses: Enzyme inhibitors. Synonyms: MDL 101731; FMdC; KW 2331; MDL 101731; KW2331; MDL101731; Tezacitabine; MDL 101,731; FMdC. CAS No. 130306-02-4. Molecular formula: C10H12FN3O4. Mole weight: 257.221. | |
