Modified natriuretic 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, decreasing arterial blood pressure and in some embodiments an improved half-life in circulation as compared to unmodified counterpart natriuretic compounds. Oral, parenteral, enteral, subcutaneous, pulmonary, 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 hBNP compound are also disclosed, having an amino acid sequence that is other than the native sequence.
本发明公开了改性利钠肽化合物及其共轭物。具体而言,提供了至少连接有一个修饰基团的hBNP的共轭形式。这些改性利钠肽化合物共轭物保留了刺激cGMP产生、结合NPR-A受体、降低动脉血压以及在某些实施例中相对于未经改性的对应利钠肽化合物具有改善的循环半衰期的活性。这些化合物和共轭物的口服、静脉注射、肠内、皮下、肺部和静脉形式可作为治疗和/或治疗心脏病症,特别是充血性心力衰竭的治疗。还公开了包含具有各种长度和构型的寡聚结构的修饰基团。此外,还公开了hBNP化合物的类似物,其氨基酸序列与天然序列不同。
