Abstract:

This invention relates to the preparation and use of supported, manganese sulfide promoted molybdenum and tungsten sulfide catalysts useful for hydroprocessing processes, particularly hydrotreating. These catalysts are prepared by heating a composite of support material and precursor salt under oxygen-free conditions and in the presence of sulfur, wherein said precursor salt contains a thiometallate anion of Mo, W or mixture thereof and a cation comprising one or more promoter metals which are chelated by at least one neutral, nitrogen-containing polydentate ligand, and wherein said promoter metal comprises Mn alone or a mixture of Mn with Co, Ni, Zn, Cu or mixture thereof.

Abstract:

A new composition of matter comprising molybdenum trioxide and heterocyclic nitrogen or oxygen Lewis bases. The molybdenum trioxide, upon reaction with Lewis base, forms a layered compound characterized in that the Lewis base is covalently bonded to molybdenum atoms in molybdenum oxide layers. The layered compound has the formula LMoO. sub. 3 where L is a Lewis base containing nitrogen or oxygen electron donors and selected from the group consisting of 5- and 6-membered heterocyclic amines, amine oxides, triorganophosphates, phosphine oxides and sulfoxides. L has the steric requirement such that its cross-sectional area perpendicular to an axis running through the L-Mo covalent bond is less than about 30(A). sup. 2.

Abstract:

The invention relates to the discovery of a gene, NMD2, named after its role in the Nonsense-Mediated mRNA Decay pathway, and the protein, Nmd2p, encoded by the NMD2 gene. The amino acid sequence of Nmd2p and the nucleotide sequence of the NMD2 gene encoding it are disclosed. Nmd2p is shown herein to bind to another protein in the decay pathway, Upf1p. A C-terminal fragment of the protein is also shown to bind Upf1p and, when overexpressed in the host cell, the fragment inhibits the function of Upf1p, thereby inhibiting the nonsense-mediated mRNA decay pathway. The invention also relates to methods of inhibiting the nonsense-mediated mRNA decay pathway to stabilize mRNA transcripts containing a nonsense codon which normally would cause an increase in the transcript decay rate. Such stabilization of a transcript is useful for the production of a recombinant protein or fragment thereof. The invention also relates to methods of identifying molecules that inhibit the nonsense-mediated mRNA decay pathway, and the use of such molecules for treatment of disorders associated with nonsense mutations.

Abstract:

Supported hydroprocessing catalysts comprising a sulfide of trivalent chromium and Mo, W or mixture thereof are obtained by compositing a preselected quantity of support material with a precursor comprising a mixture of (i) a hydrated oxide of trivalent chromium and (ii) a salt containing a thiometallate anion of Mo or W and a cation comprising the conjugate acid of at least one neutral, nitrogen-containing polydentate ligand and heating the composite in the presence of sulfur and hydrogen in an oxygen-free atmosphere. These compositions have been found to be useful hydrotreating catalysts having nitrogen removal activity superior to that of commercial catalysts derived from cobalt molybdate on alumina.
