    • The present invention provides novel compositions of allosteric hemoglobin modifiers which are substantially free of impurities, specifically polymeric impurities. In one embodiment, the novel compositions contain an allosteric hemoglobin modifier compound and less than 100 ppm of the polymeric impurities generated during the preparation of this compound. Included in the present invention are novel methods for preparing allosteric hemoglobin modifiers that are substantially free of polymeric impurities. Also included in the present invention are improved methods for the purification of the product formed by the method of this invention. The novel methods of purification comprise extracting the crude composition with a water immiscible or partially immiscible solvent such as methylisobutyl ketone (MIBK) to lower amounts of impurities, specifically polymeric impurities. Also included are methods to reduce impurities by recrystallization of the crude synthesized product, followed by filtration of the recrystallized product. The present invention also includes the products made by the processes of the invention and methods for analyzing compositions comprised of these products.
    • 本发明提供基本上不含杂质,特别是聚合物杂质的变构血红蛋白改性剂的新型组合物。 在一个实施方案中,新型组合物含有变构血红蛋白改性剂化合物,并且在制备该化合物期间产生小于100ppm的聚合物杂质。 本发明包括制备基本上不含聚合物杂质的变构型血红蛋白改性剂的新方法。 本发明还包括用于纯化通过本发明方法形成的产品的改进方法。 新颖的纯化方法包括用与水不混溶或部分不混溶的溶剂如甲基异丁基酮(MIBK)提取粗组合物以降低杂质量,特别是聚合物杂质。 还包括通过粗合成产物的重结晶减少杂质的方法,然后过滤重结晶产物。 本发明还包括通过本发明的方法制备的产品和用于分析由这些产品组成的组合物的方法。

    • Provided is a compressed anti-solvent technique for manufacture of drug-containing powders for pulmonary delivery. The drug is processed in a cosolvent system including two or more mutually soluble organic solvents. Also provided are powders manufacturable by the manufacture method, including powders of substantially pure drug and powders including a biocompatible polymer for pulmonary sustained drug release applications. Also provided are packaged products including drug-containing powder in a container that is receivable by and operable with a dry powder inhaler to produce an aerosol including dispersed drug-containing particles when the inhaler is actuated.
    • 提供了用于制造用于肺部递送的含药粉末的压缩反溶剂技术。 该药物在包含两种或多种相互溶解的有机溶剂的助溶剂体系中进行处理。 还提供了可通过制造方法制造的粉末,包括基本上纯的药物和粉末的粉末,其包括用于肺持续药物释放应用的生物相容性聚合物。 还提供了包含药物的粉末在包装容器中的包装产品,该容器能够通过干粉吸入器接收和操作,以在吸入器致动时产生包含分散的含药颗粒的气溶胶。
