摘要:
Cyclic oxyguanidine pyrazinone compounds are described, including compounds of the Formula I: 1 wherein R3, R4, R5, W, and A are as set forth in the specification, as well as hydrates, solvates or pharmaceutically acceptable salts thereof. The compounds of the invention are potent inhibitors of proteases, especially trypsin-like serine proteases, such as chymotrypsin, trypsin, thrombin, plasmin and factor Xa. Certain of the compounds exhibit antithrombotic activity via direct, selective inhibition of thrombin. Compositions for inhibiting loss of blood platelets, inhibiting formation of blood platelet aggregates, inhibiting formation of fibrin, inhibiting thrombus formation, and inhibiting embolus formation are described. Other uses of compounds of the invention are as anticoagulants either embedded in or physically linked to materials used in the manufacture of devices used in blood collection, blood circulation, and blood storage, such as catheters, blood dialysis machines, blood collection syringes and tubes, blood lines and stents. Additionally, the compounds can be detectably labeled and employed for in vivo imaging of thrombi.
摘要:
The present invention is a multi-well vessel such as a microtiter plate, made from a plastic material formulated for increased thermal conductivity. In a preferred embodiment, the plastic material is a thermally conductive formulation of a cyclic polyolefin, syndiotactic polystyrene, polycarbonate, or liquid crystal polymer, with a melting point greater than 130null C. and exhibiting very low intrinsic fluorescent properties. A conductive medium, such as conductive carbon black, is included in the formulation of the plastic material at about 5% or greater by weight to increase thermal conductivity. To further increase thermal conductivity, a thermally conductive ceramic filler, such as a Boron Nitride filler, may be added to the formulation. A polymeric surfactant may also be added to the formulation for increased performance. The invention may also include a flat piece of conductive material attached to the flat bottom of the plate to impart conductivity and flatness to the part. Alternatively, the flat bottom surface of the plate may be metallized or coated with a flat layer of conductive material. The plate may also include a transparent lid, or cover, preferably made from polycarbonates, polypropylenes, or cyclic olefins or from multi-layer films made from two or more clear materials with desired barrier properties. Additionally, a fluorescent grade of polymer, such an epoxy prepared with a fluorescent die, can be embedded at a particular position on the plate to help indicate when the lights on the test equipment are in operation.

摘要:
The present invention provides a library of compounds, each comprised of a common aminobenzenedicarboxylic acid core structure (scaffold) that serves as a template for synthesizing approximately 10.sup.1 -10.sup.6 compounds which are analogs of the scaffold. The library is employed to study ligand binding by biological receptors, such as enzymes, G-protein coupled receptors and membrane channels. For example, certain individual compounds within the library selectively bind and inhibit the action of trypsin-like serine proteases. The present invention also relates to combinatorial synthetic methods for making such libraries of compounds. Additionally, the present invention relates to novel scaffold-modified solid supports, particularly scaffold-modified polymer resins and methods for preparing said resins. Further, the present invention is directed to methods for screening a compound or plurality of compounds made according to the synthetic methods disclosed herein, which comprise using the compounds in suitable assays developed for detecting the compounds' utility as pharmaceutical agents.
摘要:
A computer based, iterative process for generating chemical entities with defined physical, chemical and/or bioactive properties. During each iteration of the process, (1) a directed diversity chemical library is robotically generated in accordance with robotic synthesis instructions; (2) the compounds in the directed diversity chemical library are analyzed to identify compounds with the desired properties; (3) structure-property data are used to select compounds to be synthesized in the next iteration; and (4) new robotic synthesis instructions are automatically generated to control the synthesis of the directed diversity chemical library for the next iteration.
