The present invention relates to the solid state of 6-(1H-imidazol-1-yl)-2-phenylquinazoline (I) and therefore to novel crystalline forms of the base and of pharmaceutically acceptable salts and solvates thereof, and also to methods for preparing them, to the respective pharmaceutical formulations and to their therapeutic use.
Compound (I) may be obtained as the free base in five different crystalline forms, three polymorphic forms and two hydrates. Some pharmaceutically acceptable salts of (I) that have physicochemical characteristics acceptable for pharmaceutical development were obtained, and the respective polymorphic forms and/or hydrates were characterized.
本发明涉及6-(
1H-咪唑-1-基)-
2-苯基喹唑啉(I)的固态,因此涉及该基础物质和其药学可接受的盐和溶剂化合物的新晶体形式,以及制备它们的方法,相应的制药配方及其治疗用途。化合物(I)可以以五种不同的晶体形式,三种多形形式和两种
水合物的形式获得其自由碱。已获得了一些药学可接受的(I)盐,其物理
化学特性适合药物开发,并对相应的多形形式和/或
水合物进行了表征。
