    • Peptides that are designed to inhibit the biological activity of the IL-1R type 1 receptor and inhibit IL-1R/IL-1RacP related cell signaling and biological activity are disclosed. Compositions comprising IL-1R antagonists of the present invention are useful in the treatment of IL-1 related diseases or conditions such as arthritis, rheumatoid arthritis, osteoarthritis, and inflammatory bowel disease as well as other chronic or acute inflammatory diseases. This invention also discloses an isolated compound having an IL-1R antagonist activity, said compound being selected from the group consisting of: a peptide comprising the amino acid sequence RYTPELX, wherein R, Y, T, P, E, L, refer to their corresponding amino acids, and X is selected from no amino acid and alanine (A); and a derivative of (a) wherein the derivative incorporates one, two or three amino acid modification selected from an amino acid addition, deletion or substitution in the RYTPEL portion of the peptide, and wherein said derivative maintains its antagonist IL-1R activity.
    • 公开了旨在抑制IL-1R 1型受体的生物活性并抑制IL-1R / IL-1RacP相关细胞信号传导和生物学活性的肽。 包含本发明的IL-1R拮抗剂的组合物可用于治疗IL-1相关疾病或病症如关节炎,类风湿性关节炎,骨关节炎和炎性肠病以及其它慢性或急性炎性疾病。 本发明还公开了具有IL-1R拮抗剂活性的分离化合物,所述化合物选自:包含氨基酸序列RYTPELX的肽,其中R,Y,T,P,E,L是指它们 相应的氨基酸,X选自无氨基酸和丙氨酸(A); 和(a)的衍生物,其中所述衍生物包含选自肽的RYTPEL部分中的氨基酸添加,缺失或取代的一个,两个或三个氨基酸修饰,并且其中所述衍生物维持其拮抗剂IL-1R活性。
