    • The present invention provides a synthetic polypeptide which is a random pentapolymer or a salt thereof, comprising alanine, glutamic acid, lysine, tyrosine and phenylalanine, useful for the treatment of autoimmune diseases and, in particular multiple sclerosis (MS). The pentapolymer is a copolymer of alanine, glutamic acid, lysine, tyrosine and phenylalanine, which are randomly polymerized into a polypeptide, thereby forming a random copolymer, or a salt thereof The present invention is based in part on the unexpected finding that the novel pentapolymer shows unexpected oral bioavailability, an advantageous release profile when formulated into a depot drug delivery system and advantageous synergistic activity in autoimmune diseases when combined with an additional therapeutic agent. According to a first aspect, the present invention provides a pentapolymer or a salt thereof, which is a linear random copolymer of alanine, glutamic acid, lysine, tyrosine and phenylalanine.
    • 本发明提供了一种合成多肽,其是无机五聚物或其盐,其包含丙氨酸,谷氨酸,赖氨酸,酪氨酸和苯丙氨酸,其可用于治疗自身免疫疾病,特别是多发性硬化(MS)。 五元共聚物是丙氨酸,谷氨酸,赖氨酸,酪氨酸和苯丙氨酸的共聚物,其随机聚合成多肽,从而形成无规共聚物或其盐。本发明部分基于意想不到的发现,即新的五元共聚物 显示出意想不到的口服生物利用度,当配制成贮库药物递送系统时的有利的释放特征,以及当与另外的治疗剂组合时,在自身免疫性疾病中的有利的协同活性。 根据第一方面,本发明提供了一种五聚物或其盐,它是丙氨酸,谷氨酸,赖氨酸,酪氨酸和苯丙氨酸的线性无规共聚物。
