A compound includes a carrier molecule wherein the carrier molecule is linked to a further molecule, wherein the further molecule is at least one cyclic peptide in which the cyclic peptide portion thereof contains at least one sequence encoding a cell receptor recognizing peptide (RRP) and with the proviso that the compound is not a naturally occurring receptor agonist or antagonist. Preferably, the RRP is a receptor specific for Hepatic Stellate Cells (HSC) or a receptor that is up-regulated on HSC during disease. The RFP may be chosen from among a PDGF receptor, a collagen type VI receptor, cytokine receptor(s) such as TGBβ, INFα and interleukinβ. The cyclic portion of the peptide can contain at least one amino acid sequence RGD or KPT. The compounds can be used as an active targeting ingredient for manufacturing a pharmaceutical composition for therapy, prophylaxis or diagnosis of a disease chosen from fibrotic disease, sclerotic disease, and chronic or acute inflammatory processes including glomeruloscherosis, interstitial fibrosis, lung fibrosis, atherosclerosis, rheumatoid arthritis, Crohns disease, colitis ulcerosa, glomerulonephritis and sepsis, and particularly for targeting HSC. Pharmaceutical compositions contain the above-compound(s).
一种化合物包括载体分子,其中载体分子与另一种分子相连,另一种分子是至少一种环肽,其中环肽部分包含至少一种编码细胞受体识别肽(RRP)的序列,但该化合物不是天然存在的受体激动剂或拮抗剂。最好,RRP 是肝星状细胞(HSC)的特异性受体或在疾病期间 HSC 上调的受体。RFP可选自PDGF受体、VI型胶原受体、细胞因子受体(如TGBβ、INFα和白细胞介素β)。肽的环状部分可包含至少一个
氨基酸序列 RGD 或 K
PT。这些化合物可用作活性靶向成分,用于制造药物组合物,以治疗、预防或诊断选自纤维化疾病、硬化性疾病和慢性或急性炎症过程的疾病,包括肾小球硬化、间质纤维化、肺纤维化、动脉粥样硬化、类风湿性关节炎、克罗恩病、溃疡性结肠炎、肾小球肾炎和败血症,特别是用于靶向造血干细胞。药物组合物含有上述化合物。
