Toward the discovery of dual HCMV-VZV inhibitors: Synthesis, structure activity relationship analysis, and cytotoxicity studies of long chained 2-uracil-3-yl-N-(4-phenoxyphenyl)acetamides. Bioorganic & medicinal chemistry, 2015, Nov-01, Volume: 23, Issue:21 The need for novel therapeutic options to fight herpesvirus infections still persists. Herein we report the design, synthesis and antiviral evaluation of a new family of non-nucleoside antivirals, derived from 1-[ω-(4-bromophenoxy)alkyl]uracil derivatives--previously reported inhibitors of human cytomegalovirus (HCMV). Introduction of the N-(4-phenoxyphenyl)acetamide side chain at N(3) increased their potency and widened activity spectrum. The most active compounds in the series exhibit submicromolar activity against different viral strains of HCMV and varicella zoster virus (VZV) replication in HEL cell cultures. Inactivity against other DNA and RNA viruses, including herpes simplex virus 1/2, points to a novel mechanism of antiviral action. Topics: Acetamides; Antiviral Agents; Cell Line; Cell Proliferation; Cytomegalovirus; DNA Viruses; Drug Evaluation, Preclinical; Herpesvirus 3, Human; Humans; RNA Viruses; Structure-Activity Relationship; Uracil; Virus Replication	2015
Hydrophilic interaction chromatography using amino and silica columns for the determination of polar pharmaceuticals and impurities. Journal of chromatography. A, 2001, Apr-13, Volume: 913, Issue:1-2 Hydrophilic interaction chromatography (HILIC) is described as a useful alternative to reversed-phase chromatography for applications involving polar compounds. In the HILIC mode, an aqueous-organic mobile phase is used with a polar stationary phase to provide normal-phase retention behavior. Silica and amino columns with aqueous-acetonitrile mobile phases offer potential for use in the HILIC mode. An examination of the retention and separation of several pyrimidines, purines, and amides on silica and amino columns from three manufacturers revealed that mobile phases should contain a buffer or acid for pH control to achieve similar and reproducible results among columns from different sources. Amino columns may also be used in an anion-exchange mode, which provides an advantage for some applications. In some cases, silica can provide different selectivity and better separation than an amino column. Example applications include: low-molecular-mass organic acids and amides as impurities in non-polar drug substances, 5-fluorouracil in 5-fluorocytosine, guanine in acyclovir, and different selectivity for polar basic compounds compared to an ion-pairing system. Topics: Acetamides; Acyclovir; Amines; Chromatography, High Pressure Liquid; Chromatography, Ion Exchange; Flucytosine; Fluorouracil; Guanine; Molecular Weight; Pharmaceutical Preparations; Sensitivity and Specificity; Silicon Dioxide	2001
