The present invention provides a pharmaceutically acceptable strong acid salt of 3-(4-amino-1-oxo-1,3-dihydro-isoindol-2-yl)piperidine-2,6-dione, a solvate thereof, a process for preparing the same and use in the preparation of a medicament for treating diseases or physiological abnormities by inhibiting inflammatory factors or angiogenesis. The water-solubility of the pharmaceutically acceptable strong acid salts of 3-(4-amino-1-oxo-1,3-dihydro-isoindol-2-yl)piperidine-2,6-dione is quite higher than that of 3-(4-amino-1-oxo-1,3-dihydro-isoindol-2-yl)piperidine-2,6-dione. The present invention also provides polymorphs of a pharmaceutically acceptable strong acid salt of 3-(4-amino-1-oxo-1,3-dihydro-isoindol-2-yl)piperidine-2,6-dione and a solvate thereof.
本发明提供了一种3-(4-氨基-1-氧代-1,3-二氢异吲哚-2-基)哌啶-2,6-二酮的药用可接受的强酸盐,其溶剂化物,其制备方法以及在制备用于抑制炎症因子或血管生成的药物治疗疾病或生理异常方面的用途。药用可接受的3-(4-氨基-1-氧代-1,3-二氢异吲哚-2-基)哌啶-2,6-二酮的强酸盐的水溶性相当高于3-(4-氨基-1-氧代-1,3-二氢异吲哚-2-基)哌啶-2,6-二酮。本发明还提供了药用可接受的3-(4-氨基-1-氧代-1,3-二氢异吲哚-2-基)哌啶-2,6-二酮的强酸盐及其溶剂化物的多晶形态。
