Patent CA-2278022-A1 (CA)
Title: Method to produce a transition metal carbide from a partially reduced transition metal compound
Inventor: BARKER HOBART A
IPC: C01B32/949
Filed: 1998-03-24
Abstract: A transition metal carbide (for example, WC) is prepared by the following steps. A carbon-precursor mixture is formed by mixing a precursor comprised of (i) a transition metal oxide (for example, WOx) and (ii) a material selected from the group consisting of: a transition metal (for example, W); a transition metal carbide (for example, WC) and a substoichiometric carbide (W2C), in the presence of a source of carbon (for example, carbon black) in an amount sufficient to form a reduced mixture comprised of the transition metal carbide and substoichiometric transition metal carbide, wherein the amount of the transition metal oxide and transition metal is essentially zero in said reduced mixture. The carbon-precursor mixture is heated in a reducing atmosphere (for example, 5 percent hydrogen in argon) to a reducing temperature and for a time sufficient to produce the reduced mixture. The reduced mixture is milled in the presence of a source of carbon in an amount sufficient to carburize the substoichiometric transition metal carbide to form the transition metal upon heating in a reducing atmosphere. Finally, the milled reduced mixture is heated in a reducing atmosphere to a carburizing temperature that is greater than the reducing temperature for a time sufficient to carburize the substoichiometric transition metal carbide to form the transition metal carbide of this invention (for example, WC).

Title: Drug screen targeting lipoprotein-membrane anchorage
Inventor: KLOOG YOEL
IPC: G01N33/566
Filed: 1998-02-26
Abstract: A drug screening assay for identifying compounds for their potential effects on the long chain fatty acid dependant intracellular membrane anchorage sites of lipoproteins. Membranes-anchoring-target are incubated in the presence of the compound to be tested and the proportion of the target that is released by the compound is detected and quantitated. The benchmark for this assay are the prenylated proteins such as the farnesylated and palmitoylated oncogenic ras trigger proteins which are displaced from their anchorage at the intracellular plasma membrane by derivatives of Farnesyl Thiosalicylic Acid (FTS). The assay is adaptable to flexibly assay a large variety of anchored targets using a wide range of labeling and detection techniques in test wells, tissue culture, and in animals as injected cells or transgenic, thereby directly addressing a wide range of pharmacologically relevant needs.
