  • Diol-containing renin inhibitors
    Patent number: 5260278
    Abstract: The invention concerns novel renin-inhibitory peptides which are useful for treating renin-associated hypertension, congestive heart failure, hyperaldosteronism, and diseases caused by retroviruses including HTLV-I and -III. Processes for preparing the peptides, compositions containing them, and methods of using them are included. Also included is a diagnostic method which uses the compounds to determine the presence of renin-associated hypertension, or hyperaldosteronism.
    Type: Grant
    Filed: April 1, 1991
    Date of Patent: November 9, 1993
    Assignee: Warner-Lambert Company
    Inventors: Richard Himmelsbach, John C. Hodges, James S. Kaltenbronn, William C. Patt, Joseph T. Repine, Ila Sircar

  • Bidirectional ultrafiltration apparatus
    Patent number: 4849102
    Abstract: A pair of membrane ultrafiltration cells are mounted one on each of the front and back surfaces of a central bidirectional manifold having an exit and an entrance conduit connector on the same side wall of the manifold. The manifold takes fluid to be filtered from a source through a conduit connector for full flow delivery to each filter cell and collects filtered fluid from each cell to be dispensed through a further connector. Plural manifolds may be connected to each other in a filter system for greatly increased filtering capacity.
