Antiviral Activity of 5-substituted Pyrimidine Nucleoside Analogues
From a large series of 5—substituted 1—(2—deoxy——D—ribofuranosyl)—ura— cil (dUrd) , 1—(2—deoxy——D—ribofuranosyl)—cytosine (dCyd) and 1—(—D—arabinofurano— syl)—uracil (araU) analogues that have been evaluated for their antiviral proper— ties, the (E)—5—(2—bromovinyl)derivatives emerged as the most potent and most selec— tive antiherpes agents. (E)—5—(2—Bromovinyl)—dUrd (BVDU) and its congeners, ...
متن کاملAnti-hepatitis B virus activity of new substituted pyrimidine acyclic nucleoside analogues.
A number of N-substituted pyrimidine acyclic nucleosides were synthesized by coupling reaction of 2-(2-chloroethoxy)ethyl acetate or (2,2-dimethyl-1,3-dioxolan-4-yl)methyl 4-methylbenzenesulfonate with the corresponding base followed by deprotection. The synthesized compounds were tested for their antiviral activity against hepatitis B virus (HBV). The plaque reduction infectivity assay was use...
متن کاملFirst Principles Calculation of pKa Values for 5-Substituted Uracils
Oxidation of uracil (U) and thymine (5-Me-U) are believed to play a role in genetic instability because of the changes these oxidations cause in the ionization constants (pKa values), which in turn affects the base pairing and hence coding. However, interpretation of the experimental evidence for the changes of pKa with substitution at U has been complicated by the presence of two sites (N1 and...
متن کاملN - 1 regioselective Michael - type addition of 5 - substituted uracils to ( 2 - hydroxyethyl ) acrylate S ł
N-1 regioselective Michael-type addition of 5-substituted uracils to (2-hydroxyethyl) acrylate is presented. The reactions were performed in polar aprotic solvents and with avoidance of polymerization of acrylic substrate. The obtained adducts may serve as versatile substrates for further functionalization, e.g. into (3-uracil-1-yl)propanoic acids or transformations, with participation of hydro...
