Modified n atriuretic compounds and conjugates thereof are disclosed in the present invention. In particular, conjugated forms of hBNP are provided that include at least one modifying moiety attached thereto. The modified natriuretic compound conjugates retain activity for stimulating cGMP production, binding to NPR-A receptor, and in some embodiments an improved half-life in circulation as compared to unmodified counterpart natriuretic compounds. Oral, parenteral, subcutaneous, and intravenous forms of the compounds and conjugates may be prepared as treatments and/or therapies for heart conditions particularly congestive heart failure. Modifying moieties comprising oligomeric structures having a variety of lengths and configurations are also disclosed. Analogs of the n atriuretic compound are also disclosed, having an amino acid sequence that is other than the native sequence.
本发明公开了经修饰的利尿化合物及其共轭物。特别是,本发明提供了 hBNP 的共轭形式,其中包括至少一个连接在其上的修饰分子。修饰的利钠化合物共轭物保留了刺激 cGMP 生成、与 NPR-A 受体结合的活性,在某些实施方案中,与未修饰的对应利钠化合物相比,其在循环中的半衰期得到了改善。口服、肠外、皮下和静脉注射形式的化合物和共轭物可制备成治疗和/或治疗心脏疾病,特别是充血性心力衰竭的药物。此外,还公开了由具有各种长度和构型的低聚物结构组成的修饰分子。此外,还公开了具有不同于原生序列的氨基酸序列的利尿化合物类似物。
