Inhibition constants (Kis) were used as an estimate of the ability of various nucleoside analogs to be recognized as substrates by the deoxythymidine kinases (dTKs) of a 5-methoxymethyldeoxyuridine-resistant (MMdUr) mutant of herpes simplex virus type 1 (HSV-1) and its parent wild-type (wt). The Kis for the 5-position analogs MMdU, [E]-5-(2-bromovinyl)deoxyuridine, bromodeoxyuridine, and iododeoxyuridine were increased approx. 3-5-fold, suggesting that they were poorer substrates for the MMdUr dTK than for the wt dTK. With the 2′ analogs arabinosylthymine and 2′-fluoro-5-methylarabinosyluracil, however, the Kis were increased to a much greater extent, 80- and 240-fold, resp. These findings suggest that the resistance of the mutant MMdUr to these analogs may be due to a mutation(s) in the viral dTK that directly affects binding at the 2′ recognition site and indirectly at the 5, while still allowing substantial activity with the natural substrate deoxythymidine. 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: 69256-17-3HPLC of Formula: 69256-17-3).

The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.HPLC of Formula: 69256-17-3

In order to find the effects of unnatural nucleosides on the stability of duplex, several oligonucleotides containing 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-uracil (FAU), -cytosine (FAC) and -thymine (FMAU) were synthesized by two alternative approaches: phosphoramidite method on an ABI 392 synthesizer and H-phosphonate procedure on the authors’ GeneSyn I universal module synthesizer. It was shown from the melting profiles that the presence of FMAU has a large stabilizing effect on the duplex. Replacement of thymidine with FAU, or deoxycytidine with FAC resulted in the formation of less stable duplexes. Temperature-dependent CD spectroscopy demonstrated that the structures of the fluorine containing oligomers are very similar to those of unmodified oligomers. 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: 69256-17-3Application of 69256-17-3).

Mice were treated i.v. with 2-14C-labeled 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-methyluracil (I) [69256-17-3] (501 μCi/365 mg/kg). The 24 h urine collection contained 93% of the radioactivity administered. HPLC anal. of the urine showed 97.2, 1.5, 0.2, and 0.6% of the recovered radioactivity as I and as metabolites A, B, and C, resp. Fractionation of the urine by HPLC yielded 0.98 mg of metabolite A and 0.3 mg of metabolite C. UV, NMR, HPLC, and mass spectral analyses were used to elucidate the structures of metabolites A and C. The spectra for metabolite A were identical to those of the synthesized compound 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-hydroxymethyluracil  [94817-51-3].

The parallel and antiparallel triplex formation and stability of self complementary oligonucleotides containing 2′-fluoro-arabinosyl thymine and 5-methyl-2′-deoxycytidine was written by Ren, Wu Yun; Watanabe, Kyoichi A..

We examined the effects of 1-(2-deoxy -2-fluoro-β-D-arabinofuranosyl)-thymine (or FMAU, a potent antiviral nucleoside) on the stability of duplex and triplexes. When compared the stability of the self-complementary 5′-A5T5 duplex with 5′-A5X5 (X = FMAU), duplex containing FMAU has much higher melting temperature (Tm). 5-A6T5T3X3T5F3X3 and T3X3T5A6T5F3X3 form the parallel and antiparallel triplexes T3X3:A6:X3T3, resp. The former exhibited the typical T:A:T triplex behavior with only one melting temperature at 70 °C and 45 °C in 1.0 M and 0.2 M NaCl solution, resp., whereas the latter has two Tm values at 56 °C and 28 °C in 1.0 M solution FMAU clearly stabilize the triplex structure as A6T22 which forms the parallel triplex T6:A6:T6 has also only one Tm at 54 °C and 37 °C and 37 °C in high and low salt concentration solutions, resp. A 31mer 5′-TCCTCCTTTTTTAGGAGGATTTTTTGGTGGT and 5′-TCCTCCTTTTTTAGGAGGATTTTTTX’X’TX’X’T (X’ = 2′-deoxy-5-methylcytidine) were prepared to study their triplex forming potential. The former was found to have a weak interaction of the Watson-Crick duplex with the mismatched third-strand at all pH. The latter formed a stable triplex at lower pH consistent with required protonation on the 5-methylcytosine base. For these studies we developed a simple PC desktop spreadsheet program to calculate the first derivative profile of the melting curve data. 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: 69256-17-3Electric Literature of C10H13FN2O5).

Comparison of antiviral effects of mismatched double-stranded RNA and 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyl-uracil (D-FMAU) against duck hepatitis B virus in vitro was written by Ijichi, K.; Ida, S.; Machida, H.; Shimada, K..

The effects of mismatched double-stranded RNA (mdsRNA) and 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyl-uracil (D-FMAU) on the replication of duck hepatitis B virus (DHBV) were examined in duck primary hepatocytes infected with DHBV. The 50% inhibitory doses of m-dsRNA and D-FMAU for the replication of DHBV DNA were 0.34±0.06 and 0.007±0.001 μg mL-1, resp. Mismatched dsRNA slightly inhibited the intermediate DHBV DNA at a concentration as high as 1.0 μg mL-1, whereas the DHBV replicative form was markedly suppressed in the presence of 0.1 μg mL-1 of D-FMAU. On the other hand, m-dsRNA inhibited DHBV DNA replication even after the compound was removed from the culture medium, while the efficacy of D-FMAU did not persist after the cessation of treatment. The anal. of DHBV RNA revealed that m-dsRNA markedly inhibited DHBV RNA transcription, while D-FMAU only marginally suppressed the transcription of viral RNA. These results indicate that m-dsRNA inhibits DHBV RNA transcription rather than DHBV DNA replication and that this suppression of DHBV RNA transcription may produce persistent inhibition of DHBV replication. 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).

The pyrimidine ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives.
