Nucleoside analogs with modified sugar moieties have been examined for their substrate/inhibitor specificities towards highly purified deoxycytidine kinase (dCK) and thymidine kinases (tetrameric high-affinity form of TK1-cytoplasmic and TK2-mitochondrial) from human leukemic spleen. In particular, the analogs included the mono- and di-O’-Me derivatives of dC, dU and dA, syntheses of which are described. In general, purine nucleosides with modified sugar rings were feebler substrates than the corresponding cytosine analogs. Sugar-modified analogs of dU were also relatively poor substrates of TK1 and TK2, but were reasonably good inhibitors, with generally lower Ki values vs TK2 than TK1. An excellent discriminator between TK1 and TK2 was 3′-hexanoylamino-2′,3′-dideoxythymidine, with a Ki of âˆ?00 μM for TK1 and âˆ?.1 μM for TK2. 3′-OMe-dC was a superior inhibitor of dCK to its 5′-O-Me congener, consistent with possible participation of the oxygen of the (3′)-OH or (3′)-OMe as proton acceptor in hydrogen bonding with the enzyme. Surprisingly α-dT was a good substrate of both TK1 and TK2, with Ki values of 120 and 30 μM for TK1 and TK2, resp.; and a 3′-branched α-L-deoxycytidine analog proved to be as good a substrate as its α-D-counterpart. Several 5′-substituted analogs of dC were good non-substrate inhibitors of dCK and, to a lesser extent, of TK2. Finally, some ribonucleosides are substrates of the foregoing enzymes; in particular C is a good substrate of dCK, and 2′-OMe-C is an even better substrate than dC. 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: 56632-83-8Recommanded Product: 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one).

We investigated structure-activity relationships of 5-substituted uracil nucleoside analogs for their selective antiviral activity against varicella-zoster virus (VZV) and affinity for VZV thymidine kinase (TK). Anti-proliferative activity of the compounds was measured using human lymphoblastoid cells. Most 2′-deoxyribofuranosyluracil, arabinofuranosyluracil (araU) and 2′-deoxy-2′-fluoro-arabinofuranosyluracil derivatives showed selective anti-VZV activity as well as activity against herpes simplex virus types 1 and 2. 2′-Deoxyuridine derivatives showed higher affinity than the corresponding araU analogs. A correlation was seen between the 50% EDs for VZV and the Ki values for VZV TK, except for 5-ethyl-2′-deoxyuridine and 5-Et araU that showed relatively high affinity for VZV TK without showing any activity against VZV. 5-Halogenovinyluracil nucleosides showed the highest affinity and the most potent and selective anti-VZV activity. 2′-Deoxy-2′-fluoro-arabinofuranosyluracil derivatives exhibited high anti-VZV potency though they showed relatively low affinity for VZV TK. Some 3′-deoxythymidine analogs having anti-human immunodeficiency virus activity were inactive against herpesviruses. 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: 69256-17-3Quality Control of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).

Several 2′-fluoroarabino-2′,3′-dideoxy- and 2′-fluoro-2′,3′-unsaturated 2′,3′-dideoxy pyrimidine nucleoside analogs are reported. The saturated analogs 1-(2,3-dideoxy-2-fluoro-β-D-threo-pentofuranosyl)thymine or -uracil (I; R = Me or H, resp.) were readily prepared from the resp. 2′-deoxy-2′-fluoroarabinosyl nucleoside analog by radical deoxygenation of 3′-OH. The cytosine derivative II and the unsaturated compounds III and IV were also synthesized. The novel compounds were evaluated in vitro against human immunodeficiency virus (HIV) (LAV isolate). II was the most active of the newly synthesized substances against HIV with an ID50 of 0.8 μg/mL; ddC had an ID50 of 0.00m μg/mL. Because of its potency in the initial tests, II was further evaluated in both T cells and macrophage/monocyte cell lines, with several different isolates of HIV. Although II exhibited good antiviral activity in these systems, it was less active than AZT in these assays. At 1 μM the inhibition of CFU-GM by II was found to be 35-40%; this is slightly higher than seen with AZT.

2′-fluoro-5-[11C]-methyl-1-β-d-arabinofuranosyluracil ([11C]-FMAU): a potential nucleoside analog for in vivo study of cellular proliferation with PET was written by Conti, Peter S.; Alauddin, Mian M.; Fissekis, John R.; Schmall, Bernard; Watanabe, Kyochi A.. And the article was included in Nuclear Medicine and Biology on August 31,1995.SDS of cas: 69256-17-3 The following contents are mentioned in the article:

Rapid in vivo catabolism limits the use of currently available radiotracers used in tumor proliferation studies with positron emission tomog. (PET). This is manifested by the need to develop complex math. models to interpret kinetic and metabolite data obtained from imaging studies with agents such as carbon-11 labeled thymidine. A potential carbon-11 labeled radiotracer for cellular proliferation, 2′-fluoro-5-([11C]-methyl)-1-β-D-arabinofuranosyluracil (FMAU), has been prepared using a previously described method for preparation of [11C]methyl-thymidine where selective alkylation of a pyrimidyl dianion is accomplished with [11C]methyl iodide at the 5-position of the pyrimidine ring. FMAU shares many in vivo characteristics of thymidine, including cellular transport, phosphorylation by mammalian kinase, and incorporation into DNA. Most importantly, in vivo catabolism of FMAU is limited, potentially yielding simplified kinetic models for determination of cellular proliferation with positron emission tomog. 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: 69256-17-3SDS of cas: 69256-17-3).

Alterations in the recognition of nucleoside analogs as substrates by the deoxythymidine kinase of a 5-methoxymethyldeoxyuridine-resistant mutant of herpes simplex virus type 1 was written by Veerisetty, V.; Veerisetty, Indira K.; Gentry, Glenn A.. And the article was included in Journal of General Virology on December 31,1983.HPLC of Formula: 69256-17-3 The following contents are mentioned in the article:

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).

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.

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.
