Abstract: A ketorolaco derivative as shown in formula (I) has a better half-life and stability, has good pharmacokinetic properties, and has a higher stability in vitro; and as a preparation, the ketorolaco derivative can enhance efficacy and reduce toxicity. The present invention well improves the defects of frequent administration, gastrointestinal side effects, poor compliance and the like in traditional ketorolaco preparations.

Abstract: The application related to an ibuprofen ester derivative and an emulsion preparation thereof. A carboxyl group of racemic ibuprofen or S-ibuprofen is derivatized so that Compound N9 and a dextrorotatory enantiomer N9(S) thereof are obtained and further prepared into an emulsion preparation, which overcomes the problems of safety and compliance of patients existing in clinical application of existing ibuprofen/dexibuprofen injections and achieves the purposes of reducing vascular irritation, increasing clinical use approaches, and improving the stability of preparations in clinical applications.

Abstract: Provided is an ibuprofen ester prodrug represented by Structural Formula (1), a racemate, stereoisomer or pharmaceutically acceptable salt or solvate thereof, or a solvate of a pharmaceutically acceptable salt thereof. Further provided are a method for preparing the compound, a pharmaceutical composition containing the compound, and an application of the compound in preparation of nonsteroidal anti-inflammatory drugs. The pharmaceutical composition containing the ibuprofen ester prodrug may be prepared into fat emulsion injection preparations. The ibuprofen ester prodrug has good stability and good pharmacokinetic properties and overcomes the problems of ibuprofen such as a short half-life, poor stability, irritation, and incompatibility.

Abstract: Provided are an arylpropionic acid derivative represented by Formula (I), a pharmaceutical composition and a preparation method and an application thereof. The arylpropionic acid derivative has a good half-life, pharmacokinetic property and in vitro stability and can enhance efficacy and reduce toxicity after formulated into preparations, which repairs the defects of frequent administration, gastrointestinal side effects and poor patient compliance of traditional nonsteroidal anti-inflammatory drugs.
