标题:Oxidoreductase inhibitors and methods of screening and using thereof
发明人：BALENDIRAN GANESARATNAM K
摘要:The present invention relates to 1) the design and synthesis of analogs to glutathione conjugates which bind to or interact with aldose reductase (AR) through unique conformations that are distinctly different from the substrates and inhibitors of AR which are members of sugar metabolism; 2) the screening of the analogs to identify those that interact with or inhibit or enhance the activity of AR; and 3) the use of AR ligands, AR inhibitors (AR antagonsits) or AR enhancer (AR agonists) in the detection of AR activity, the modulation of AR activity, and the treatment of conditions in a subject in need of modulating AR activity. Such conditions include but not limited to cardiovascular disease, diabetes, artheriosclerosis, cancer, neoplasm, obesity, cataract, retinopathy, keratopathy, nephropathy, neurosis, thrombosis, faulty union of corneal injury and neuropathy. Examples of the treatment include the use of fibrates as AR inhibitors to treat these conditions.

标 题:Synthesis process for one-step production of monomeric polyether for polycarboxylic acid water reducing agents
发明人：MA CAIFENG; LAI KE; LI YUBO
权利人:JIAHUA CHEMICALS FUSHUN NEW MAT CO LTD
摘要:Provided is a synthesis process for the one-step production of a monomeric polyether for polycarboxylic acid water reducing agents, wherein the monomeric polyether is synthesized in one step by mixing an initator and a catalyst at a temperature and a pressure, and then introducing same into a reaction kettle together with an epoxide at a certain ratio for ring opening polymerization. The synthesis process of the present invention realizes continuous production without the need of first synthesizing a prepolymer and then synthesizing a macromolecular monomeric polyether step by step, thereby improving the production efficiency. By separating four links, i.e. displacement, polymerization, curing and neutralization, in conventional monomeric polyether production processes, the present invention more effectively controls each of the links and increases the utilization efficiency of the reaction kettle; in addition, the process is easy to control, the structure of the product is stable, and the retention of double-bonds is high.
