The present invention relates to chimeric fatty body-GRF analogs with increased biological potency, their application as anabolic agents and in the diagnosis and treatment of growth hormone deficiencies. The chimeric fatty body-GRF analogs include an hydrophobic moiety (tail), and can be prepared, either by anchoring at least one hydrophobic tail to the GRF, in the chemical synthesis of GRF. The GRF analogs of the present invention are biodegradable, non-immunogenic and exhibit an improved anabolic potency with a reduced dosage and prolonged activity.
本发明涉及具有增强
生物效力的嵌合脂肪体-GRF类似物,它们的应用作为合成代谢剂以及在生长激素缺乏的诊断和治疗中的应用。嵌合脂肪体-GRF类似物包括一个疏
水基团(尾部),可以通过在
化学合成GRF时将至少一个疏
水尾部锚定到GRF上来制备。本发明的GRF类似物是可
生物降解的,非免疫原性的,并且具有改善的合成代谢效力,用量减少和活性延长的特点。
