标 题:Synthesis of methotrexate-containing heterodimeric molecules
发明人：MURTHI KRISHNA K; SMITH CHASE C
权利人:GPC BIOTECH INC
摘要:The present invention relates to novel compositions of methotrexate-containing heterodimeric probe molecules, also known as chemical inducers of dimerization (CID), useful in three-hybrid assays. The invention further relates to synthesis of said compositions and their intermediates. Another aspect of the invention is a method for using the heterodimeric probe molecules described herein in drug screens to identify potential protein targets to a given ligand, optimize protein-ligand interactions, or identify potential ligands for a given protein target. In certain embodiments, the invention contemplates the synthesis of the following methotrexate-containing heterodimeric probe:

权利人:APALENE TECH CO LTD JIAXING
摘要:The present invention relates to a metallocene compound, and preparation and use thereof, and the compound can be used as a catalyst for synthesis of poly-α-olefin as lubricating base oil. The metallocene compound includes a substituted aryl group, a bridged atom, an optionally unsubstituted, 3-mono-substituted or 3,6-disubstituted 5H-indeno [1,2-b] pyridyl group or optionally unsubstituted, 3-mono-substituted or 3,6-disubstituted 5H-indeno [1,2-b] thiopyranyl group, and a metal coordination group. As a catalyst, the metallocene compound is shown to be structurally stable and high in catalytic efficiency, and the preparation of the catalyst is relatively easy in operation, high in yield, low in cost, low in pollution and easy to scale up for industrial production.

标题 :Process for synthesis of polymer compositions, polymer compositionS obtainable by the process, and use of the same
发明人：ROOS SEBASTIAN; EISENBERG BORIS; HARPE CAROLIN
权利人:ROHMAX ADDITIVES GMBH
摘要:The present invention relates to a process for synthesis of polymer compositions with reduced catalyst content, wherein ethylenically unsaturated monomers containing less than 0.5 wt % of ethylenically unsaturated monomers with at least one carboxylic group, sulfonic acid group and/or at least one phosphonic acid group relative to the total weight of the ethylenically unsaturated monomers are polymerized by means of initiators containing a transferable group of atoms and of one or more catalysts comprising at least one transition metal in the presence of ligands which can form a coordination compound with the metal catalyst or catalysts and, after the polymerization, the catalyst contained in the polymer is at least partly separated. For this purpose, the polymer composition is filtered, after the polymerization, in the presence of at least one filter aid which contains at least 0.5 wt %, relative to the total weight of the filter aid, of repeating units that contain at least one carboxylic acid group, sulfonic acid group and/or at least one phosphonic acid group.
