Following treatment of mice with 2-14C-labeled 2′-fluoro-5-iodo-1-β-D-arabinofuranosylcytosine (I) [69123-90-6], a new and potent antiherpetic agent, enzyme degradation of highly purified DNA from the small intestine and anal. of the resulting nucleosides failed to reveal the presence of unchanged I. Three metabolites were found, namely the 2′-fluoro-1-β-D-arabinofuranosyl nucleosides of cytosine, thymine, and 5-iodouracil. Labeled metabolites of I were also found in the DNA isolated from P815 leukemia cells of mice given I-2-14C. These metabolites are also potent antiherpetic agents. This study involved multiple reactions and reactants, such as 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one (cas: 56632-83-8Reference of 56632-83-8).

The pyrimidine derivatives can easily interact with enzymes, genetic materials, and bio components within the cell.

Structural requirements for the enzymic deamination of cytosine nucleosides was written by Kreis, W.; Watanabe, K. A.; Fox, J. J.. And the article was included in Helvetica Chimica Acta on April 19,1978.SDS of cas: 56632-83-8 The following contents are mentioned in the article:

Thirty-three 1-β-D-pentofuranosylcytosine nucleosides were examined as substrates of crude cytidine deaminase from mouse kidney. Modification of the aglycone moiety by substitution of a F atom at C(5) resulted in a several-fold increase in the deamination velocity relative to cytidine, whereas insertion of a Me group at C(5) decreased the deamination velocity. This decrease was even more pronounced when a Me group was substituted at C(6). Though xylosylcytosine and 3′-deoxy-3′-fluoroxylocytosine were not substrates for this deaminase, those xylofuranosylcytosines bearing good leaving groups (e.g., bromo, mesyloxy, or tosyloxy) at C(3′) were deaminated with substantial deamination velocities. This is probably due to a prior chem. reaction leading to arabino nucleosides bearing a free 3′-OH in a down configuration. A different situation was obtained with arabino nucleosides. Though 1-β-D-arabinofuranosylcytosine and 2′-deoxy-2′-fluoro-1-β-D-arabinofuranosylcytosine were substrates for this deaminase, substitution of bulky groups (e.g., chloro, bromo, or mesyloxy) at C(2′) substantially decreased the susceptibility to deamination. A hypothesis is offered to explain these differences between xylo- and arabino-cytosines. The presence of a free OH group at the 5′-position is not essential for enzymic deamination. This study involved multiple reactions and reactants, such as 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one (cas: 56632-83-8SDS of cas: 56632-83-8).

Substrate/inhibitor specificities of nucleoside analogs with modified sugar moieties towards highly purified deoxycytidine kinase (dCK) and thymidine kinases (TK1 and TK2) from human leukemic spleen have been examined Substrate activities of cytosine nucleosides vs. dCK were as follows: 2′-fluoro-dC > 2′-O-methyl-C > araC > 2′-fluoro-2′-deoxy-araC > 3′-O-methyl-dC = 3′-fluoro-2′,3′-ddC > cytosine β-L-riboside > 2′,3′-ddC > C= 1-(4-hydroxy-1,2-butadienyl)-cytosine (cytallene) = 2′-azido-dC. Modified purine nucleosides were only feeble substrates: ara-A > 2′-fluoro-2′-3′-dideoxy-ara-A = 2′-O-methyl-A. With TK1 and TK2, similar sugar-modified analogs of dU and dT were feeble substrates. Surprisingly α-dT was a relatively good substrate, as well some β-L-ribonucleosides. Several 5′-substituted analogs of dC were good non-substrate inhibitors of dCK and, to a lesser extent, of TK2. The overall data are relevant to the role of these enzymes in “”activation”” (by phosphorylation) of nucleoside analogs with antiviral and antitumor activities.

A group of 2′-fluoro and 5-substituted arabinosyl pyrimidines and a group of base-substituted pseudoisocytidine analogs were evaluated for their capacity to induce differentiation in the human promyelocytic leukemia cell line, HL-60. These compounds were compared to 1-β-D-arabinofuranosylcytosine nAra-C) by monitoring: (1) inhibition of cell growth; (2) morphol. maturation; (3) nitroblue tetrazolium (NBT) reduction; (4) expression of a myeloid differentiation antigen, Mo1; and (5) inhibition of colony formation. Exposure of logarithmically growing cells for 5 days to Ara-C, 2′-fluoro-Ara-C (FAC), 2′-fluoro-5-methyl-Ara-C (FMAC) and 2′-fluoro-5-ethyl-Ara-C (FEAC) resulted in cell growth inhibition at 50% inhibitory concentrations of 0.007, 0.11, 1.7 and 18 μM and at cytostatic concentrations of 0.1, 0.5, 5.0 and 50 μM, resp. These compounds induced granulocytic and monocytic maturation, reduction of NBT, increased expression of Mo1 antigen and a decrease or loss of both cell proliferation and colony formation in a semisolid medium. There were few, if any, cell differentiation effects for the uracil nucleosides and pseudoisonucleosides tested. Ara-C was the most cytotoxic of the compounds When comparing absolute numbers of differentiated cells, i.e. percent of pos. cells multiplied by the number of viable cells, FAC, FMAC, and FEAC were superior to Ara-C in inducing differentiation of HL-60 cells.
