    Human chromosome 12 is required for elevated HIV-1 expression in human-hamster hybrid cells (1989)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1989-10-27
    Description: Host cell factors act together with regulatory genes of the human immunodeficiency virus (HIV) to control virus production. Human-Chinese hamster ovary hybrid cell clones were used to probe for human chromosomes involved in regulating HIV gene expression. DNA transfection experiments showed that 4 of 18 clones had high levels of HIV gene expression measured by both extracellular virus production and transactivation of the HIV long terminal repeat in the presence of the trans-activator (tat) gene. Karyotype analyses revealed a 94% concordance (17/18) between human chromosome 12 and HIV gene expression. Other chromosomes had an 11 to 72% concordance with virus production.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hart, C E -- Ou, C Y -- Galphin, J C -- Moore, J -- Bacheler, L T -- Wasmuth, J J -- Petteway, S R Jr -- Schochetman, G -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):488-91.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centers for Disease Control, Atlanta, GA 30333.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2683071" target="_blank"〉PubMed〈/a〉

    Rational design of potent, bioavailable, nonpeptide cyclic ureas as HIV protease inhibitors (1994)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1994-01-21
    Description: Mechanistic information and structure-based design methods have been used to design a series of nonpeptide cyclic ureas that are potent inhibitors of human immunodeficiency virus (HIV) protease and HIV replication. A fundamental feature of these inhibitors is the cyclic urea carbonyl oxygen that mimics the hydrogen-bonding features of a key structural water molecule. The success of the design in both displacing and mimicking the structural water molecule was confirmed by x-ray crystallographic studies. Highly selective, preorganized inhibitors with relatively low molecular weight and high oral bioavailability were synthesized.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lam, P Y -- Jadhav, P K -- Eyermann, C J -- Hodge, C N -- Ru, Y -- Bacheler, L T -- Meek, J L -- Otto, M J -- Rayner, M M -- Wong, Y N -- New York, N.Y. -- Science. 1994 Jan 21;263(5145):380-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Virology Research, DuPont Merck Pharmaceutical Company, Wilmington, DE 19880.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8278812" target="_blank"〉PubMed〈/a〉
