Title: Crystalline polypeptides
Inventor: JANSSEN WILHELMUS P A
IPC: A61P25/28
Filed: 1991-05-29
Abstract: ABSTRACT      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)  dis-solving  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° 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.
