The retention behavior of minoxidil (I) and its intermediates (2,4-diamino-6-hydroxypyrimidine, 2,4-diamino-6-chloropyrimidine and 2,4-diamino-3-N-oxo-6-chloropyrimidine) was studied by using silica gel layers impregnated with tricaprylmethylammonium chloride (TCMA). The retention of the compounds increases with increasing concentration of TCMA adsorbed on the silica gel. The pH and the ionic strength of the eluents do not affect the retention at all. The retention of the solutes decreases with increasing methanol content of the eluent, because of the TCMA-desorbing effect of methanol. On the basis of these and earlier findings, it was concluded that no ion-pairing occurs during the separation A monolayer is formed on the silica surface at 0.1-0.2 M TCMA concentration in the impregnating solution, and hydrophobic interactions play an important role in the separation mechanism. This study involved multiple reactions and reactants, such as 2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4Safety of 2,6-Diamino-4-chloropyrimidine-1-oxide).

An antisense oligonucleotide is expected as an innovative drug for cancer and hereditary diseases. In this paper, we designed and synthesized DNAs containing a novel nucleoside analog, 1-(4-C-aminomethyl-2-deoxy-2-fluoro-β-D-arabinofuranosyl)thymine, and evaluated their properties. It was revealed that the analog slightly decreases the thermal stability of the DNA/RNA duplex but significantly increases the stability of DNA in a buffer containing bovine serum. Furthermore, it turned out that the DNA/RNA duplex containing the analog is a good substrate for Escherichia coli RNase H. Thus, DNAs containing the nucleoside analog would be good candidates for the development of therapeutic antisense oligonucleotides.

Bovine herpes mammillitis virus or bovine herpesvirus type 2 (BHV-2) causes ulcerative lesions on the teats and udders of infected cows. The authors investigated several nucleoside and nucleotide analogs as potential BHV-2 inhibitors. These included acyclovir, ganciclovir, 5-iodo-2′-deoxyuridine (IUdR), 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl) derivatives of 5-iodocytosine (FIAC), 5-iodouracil (FIAU), and 5-methyluracil (FMAU), and various 3-hydroxyphosphonylmethoxypropyl (HPMP) and 2-phosphonylmethoxyethyl (PME) derivatives of adenine (A), guanine (G), 2,6-diaminopurine (DAP), and/or cytosine (C). Of these, FIAU and FMAU were the most potent in cell culture, inhibiting 50% of BHV-2 plaques at <0.05 μM. HPMPA and HPMPG were active at 0.3 μM; FIAC, IUdR, and HPMPC at 1.3-2.3 μM; PMEDAP and ganciclovir at 20-25 μM; acyclovir and PMEA at >100 μM. The two most potent agents, FIAU and FMAU, inhibited uninfected embryonic bovine tracheal cell growth by 50% at >100 μM and 53 μM, resp., resulting in selectivity indexes (ratio of the 50% inhibitory concentration for cell growth to the 50% inhibitory concentration for plaque formation) of >2200 and 1100. Greater degrees of antiviral activity and selectivity were obtained in infected guinea pig embryo cells treated with FIAU, FMAU, and HPMPC. Infected cell extracts containing BHV-2-induced thymidine kinase activity phosphorylated FIAU, FMAU, and IUdR at nearly the same rate as thymidine, whereas FIAC, acyclovir, and ganciclovir were phosphorylated at ≤5% the rate of thymidine. Phosphorylation by this enzyme is required to generate the antivirally active nucleoside triphosphate in infected cells. In guinea pigs infected intravaginally with BHV-2, FMAU treatments of 1, 3.2, and 10 mg kg-1 per day for 5 days starting 1 day after virus challenge reduced vaginal lesion scores and virus titers in a dose-dependent manner. FIAU (10 μM) was as effective as 1 μM FMAU by the same regimen. A single treatment with 10 μM HPMPC was as active as daily treatments with 3.2 mg FMAU kg-1. These results indicate the potential of using antiviral agents to treat bovine herpes mammillitis virus infections in cattle, and the application of guinea pigs to study BHV-2 disease. This study involved multiple reactions and reactants, such as 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3COA of Formula: C10H13FN2O5).

Use of a standardized cell culture assay to assess activities of nucleoside analogs against hepatitis B virus replication was written by Korba, Brent E.; Gerin, John L.. And the article was included in Antiviral Research on July 1,1992.Name: 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione The following contents are mentioned in the article:

A cell culture system for the evaluation of compounds which inhibit hepatitis B virus (HBV) replication (Korba and Milman, Antiviral Res. 15:217, 1991) has been developed into a standardized assay. Toxicity of test compounds was assessed by the uptake of neutral red dye under cell culture and treatment conditions which were identical to those used for the antiviral assays. A total of 667 sep. cultures of 2.2.15 cells were evaluated for this study. In 86 untreated cell cultures, representing 15 experiments over a 24-mo period, the levels of extracellular HBV virion DNA and intracellular HBV DNA forms were found to vary by less than 2.5-fold overall. Virion DNA in serum and intracellular viral DNA replication intermediates [RI] are the two most reliable and commonly followed markers of hepadnavirus replication in patients and exptl. animals. In these assays, levels of extracellular HBV virion DNA and intracellular HBV RI were well correlated in 2.2.15 cells. Less correlation was observed between the levels of HBV virion DNA and the 3.2-kb episomal HBV genomes present in the cells. A threshold level of 22-37 intracellular replicating HBV genomes appeared to be required before virions were detected in the culture medium. The activities of several 2′-substituted and 3′-substituted deoxynucleoside analogs against HBV replication were compared using this standardized assay. Dideoxycytosine [ddC] and dideoxyguanosine [ddG] were the most selective 2′,3′-dideoxynucleosides against HBV in 2.2.15 cells. Substitution of fluorine at the 2′ position abolished the antiviral activity of ddC, but enhanced the selective antiviral activities of dideoxythymidine and dideoxyuracil. Several 2′-fluorinated pyrimidine arabinosyl furanosides, reported to be potent (but toxic) inhibitors of hepadnaviruses in vivo demonstrated relatively low selective antiviral activities in 2.2.15 cells. The current data base allows for validation of any given set of test evaluations through statistical anal. of both the pos. and the neg. treatment controls present in each experiment; thus, relevant comparisons of the selectivity of anti-HBV activities for different compounds examined in future experiments can be made. This study involved multiple reactions and reactants, such as 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3Name: 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).

Biochemical effects of 2′-fluoro-5-methyl-1-β-D-arabinofuranosyluracil and 2′-fluoro-5-iodo-1-β-D-arabinofuranosylcytosine in mouse leukemic cells sensitive and resistant to 1-β-D-arabinofuranosylcytosine was written by Chou, Ting Chao; Burchenal, Joseph H.; Schmid, Franz A.; Braun, Thomas J.; Su, Tsann Long; Watanabe, Kyoichi A.; Fox, Jack J.; Philips, Frederick S.. And the article was included in Cancer Research on October 31,1982.Recommanded Product: 69256-17-3 The following contents are mentioned in the article:

2′-fluoro-5-methyl-1-β-D-arabinofuranosyluracil (FMAU)(I) [69256-17-3], like 2′-fluoro-5-iodo-1-β-D-arabinofuranosylcytosine (FIAC)(II) [69123-90-6], has potent antiviral activity, but unlike FIAC, it also has antileukemic effects. The 2 agents and 1-β-D-arabinofuranosylcytosine (ara-C) [147-94-4] are compared herein. Concentrations inhibiting thymidine (dThd) incorporation into DNA by 50% are for FMAU, FIAC, and ara-C, resp., in L1210/0, 32, 353, and 0.2 μm and in L1210/ara-C, 17, <10,000, and 3900 μM. Other FMAU analogs, 2'-fluoro-5-ethyl-1-β-D-arabinofuranosyluracil  [69123-98-4], inhibit dThd incorporation equally in ara-C-sensitive and -resistant cells; however, their potencies are weaker than that of FMAU. Similar results are obtained when [3H]deoxyadenosine is used as a precursor of incorporation. In L1210/0 cells, incorporation of [2-14C]FMAU radioactivity into DNA is completely inhibited by dThd and deoxycytidine (dCyd), whereas the incorporation of [2-14C]FIAC radioactivity is competitively inhibited by dCyd but not appreciably by dThd. In L1210/0 cells, FMAU has little inhibitory effect on the tritium release from [5-3H]deoxyuridine but markedly inhibits the incorporation of [2-14C]deoxyuridine into DNA. FIAC, by contrast, predominately inhibits the release of tritium from [5-3H]deoxyuridine but has little effect on subsequent incorporation into DNA. Apparently, (1) FIAC, but not FMAU, is cross-resistant to ara-C; (2) FMAU is particularly effective against L1210/ara-C cells; (3) FIAC behaves metabolically like dCyd, and FMAU like dThd and dCyd; (4) dCyd and dThd may be used as chemotherapeutic modulators; and (5) FIAC predominately inhibits dThd kinase and(or) thymidine monophosphate synthetase, whereas FMAU predominately inhibits DNA polymerase and(or) nucleotide kinases. Similar conclusions were obtained when P815/0 and P815/ara-C cells were used. The relative potencies of FIAC and FMAU in inhibiting dThd incorporation into DNA in leukemic sublines correlate with cytotoxicity in vitro and chemotherapeutic effects in vivo.
