The present invention provides variants of C-type natriuretic peptide (CNP) comprising one or more deletions; additions of and/or substitutions with natural amino acids, unnatural amino acids and/or peptidomimetics (including peptide bond isosteres); amino acid extensions; and/or other chemical moieties such as, e.g., poly(ethylene glycol) and hydrophobic acids. The CNP variants are useful as therapeutic agents for the treatment of diseases responsive to CNP, including but not limited to bone-related disorders such as, e.g., skeletal dysplasias and achondroplasia, and vascular smooth muscle disorders such as, e.g., restenosis and arteriosclerosis.
本发明提供了C型利钠肽(CNP)的变体,包括一个或多个缺失;天然氨基酸、非天然氨基酸和/或肽类模拟物(包括肽键异构体)的添加和/或替代;氨基酸延伸;以及/或其他化学基团,如聚乙二醇和疏水酸。这些CNP变体可用作治疗对CNP敏感的疾病的治疗剂,包括但不限于骨相关疾病,如骨骼发育异常和软骨发育不全,以及血管平滑肌疾病,如再狭窄和动脉硬化。
