Abstract: Cyanine and related dyes, such as merocyanine, styryl and oxonol dyes, are strongly light-absorbing and highly luminescent. Cyanine and related dyes having functional groups make them reactive with amine, hydroxy and sulfhydryl groups are covalently attached to proteins, nucleic acids, carbohydrates, sugars, cells and combinations thereof, and other biological and nonbiological materials, to make these materials fluorescent so that they can be detected. The labeled materials can then be used in assays employing excitation light sources and luminescence detectors. For example, fluorescent cyanine and related dyes can be attached to amine, hydroxy or sulfhydryl groups of avidin and to antibodies and to lectins. Thereupon, avidin labeled with cyanine type dyes can be used to quantify biotinvlated materials and antibodies conjugated with cyanine-type dyes can be used to detect and measure antigens and haptens. In addition, cyanine-conjugated lectins can be used to detect specific carbohydrate groups.
Abstract: Use of the proprietary drug amiloride for the treatment of cancer types that depend on an enzymatic cascade triggered by the activation of plasminogen to plasmin by the specific activating enzyme Urokinase Plasminogen Activator (uPA). Administration of amiloride inhibits the action of uPA, inhibits the ability of the cancer cell to attract new blood supply, blocks the Na+/H+ transporter, and inhibits ornithine decarboxylase necessary for DNA synthesis. Further, in combination with amiloride, a different step in the enzymatic cascade is targeted by a secondary agent, Batimistat, for example, which is a metalloprotease inhibitor. Additionally, the use of hydrochlorothiazide promotes excretion of potassium.
