    • Disclosed is a method of obtaining an acid addition salt, crystalline compound of the formula:



              H-MetO₂-Glu-His-Phe-D-Lys-Phe-OH.



      The resulting crystalline hexapeptide salt has better intranasal absorption characteristics in comparison to amorphous hexapeptide. The method includes: a) dissolving relatively pure hexapeptide into an aqueous acidic solvent; b) concentrating the resulting solution under reduced pressure at an elevated temperature; c) measuring the pH of the concentrated solution, and if the pH is between 4.5 and 4.8, then d) maintaining the temperature of the concentrated solution between 6 and 20 o C, if the measured pH of the concentrated solution is lower than 4.5, then adding water to the solution and repeating step b) until a pH of 4.5 to 4.8 is attained; and then e) removing the crystals from the concentrated solution by filtration at lower temperatures. Previously obtained "seed" crystals comprising the acid addition salt of the hexapeptide may be used to hasten the process. Once obtained, the crystalline compound may be used in the treatment or prevention of neuropathies or dementia.
    • 公开了获得酸加成盐的方法,即下式的结晶化合物:H-MetO 2 -Glu-His-Phe-D-Lys-Phe-OH。 与无定形六肽相比,所得结晶六肽盐具有更好的鼻内吸收特征。 该方法包括:a)将相对纯的六肽溶于含水的酸性溶剂中; b)在升高的温度下将所得溶液在减压下浓缩; c)测量浓缩溶液的pH,如果pH在4.5至4.8之间,则d)将浓缩溶液的温度保持在6至20℃之间,如果浓缩溶液的测量pH低于 4.5,然后向溶液中加水并重复步骤b),直至达到4.5至4.8的pH; 然后e)在较低温度下过滤从浓缩溶液中除去晶体。 先前获得的包含六肽的酸加成盐的“晶种”晶体可用于加速该方法。 一旦获得,结晶化合物可用于治疗或预防神经病或痴呆症。
