    • The invention provides a composition comprising a mixture of polypeptides, wherein each polypeptide (a) is a copolymer of the amino acids L-glutamic acid, L-alanine, L-tyrosine, and L-lysine, and (b) may be in the form of a pharmaceutically acceptable salt; and wherein in the mixture (i) the polypeptides have an average molecular weight in the range 13,500 to 18,500 daltons, (ii) 13% to 38% of the polypeptides have a diethylamide group instead of a carboxyl group present at one end thereof, and (iii) 68% of the polypeptides have a molecular weight between 7,000 and 41,000 daltons. In an embodiment, the average molecular weight is 16,000 daltons. The invention also provides a method of treating a human subject afflicted with a neurodegenerative disease comprising administering to the human subject a therapeutically effective amount of any of the disclosed compositions so as to thereby treat the human subject.
    • 本发明提供包含多肽混合物的组合物,其中每个多肽(a)是L-谷氨酸,L-丙氨酸,L-酪氨酸和L-赖氨酸的氨基酸的共聚物,和(b)可以在 形式的药学上可接受的盐; 并且其中在所述混合物(i)中,所述多肽的平均分子量范围为13,500至18,500道尔顿,(ii)13%至38%的多肽具有二乙酰胺基团而不是存在于其一端的羧基,以及 (iii)68%的多肽具有7,000至41,000道尔顿的分子量。 在一个实施方式中,平均分子量为16,000道尔顿。 本发明还提供了治疗患有神经变性疾病的人类受试者的方法,包括向人类受试者施用治疗有效量的任何所公开的组合物,从而治疗人受试者。
