摘要:
Phenyl acetamide compounds are described, including compounds of Formula I: or a solvate, hydrate or pharmaceutically acceptable salt thereof; wherein R3-R6, R11, B, Y and W are set forth in the specification. The compounds of the invention are potent inhibitors of proteases, especially trypsin-like serine proteases, such as thrombin and factor Xa. 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:
A process for using sludge formed in the preparation of a high BN overbased alkylaryl sulfonate or overbased sulfurized alkylphenate, wherein the sludge is treated with an acidic reactant to convert large particles of the alkaline earth metal salt in the sludge into calcium sulfonate, then is reacted with an excess of alkaline earth base and either alkylaryl sulfonic acid or alkylphenol to produce a reaction product, which could be a low or high overbased alkylaryl sulfonate or overbased sulfurized alkylphenate.
