The invention provides a bioconjugates comprising a synthetic polypeptide of Formula I′ (SEQ ID NO: 1):
or an amide, an ester or a salt thereof, wherein X1, X2, X3, X4, X5, X6, X7, X8, X9, X10, X11, X12 and X13 are defined herein and a half-life extending moiety wherein the peptide and the half-life extending moiety are covalently linked or fuse, optionally via a linker. The polypeptides are agonist of the APJ receptor. The invention also relates to a method for manufacturing the bioconjugates of the invention, and its therapeutic uses such as treatment or prevention of acute decompensated heart failure (ADHF), chronic heart failure, pulmonary hypertension, atrial fibrillation, Brugada syndrome, ventricular tachycardia, atherosclerosis, hypertension, restenosis, ischemic cardiovascular diseases, cardiomyopathy, cardiac fibrosis, arrhythmia, water retention, diabetes (including gestational diabetes), obesity, peripheral arterial disease, cerebrovascular accidents, transient ischemic attacks, traumatic brain injuries, amyotrophic lateral sclerosis, burn injuries (including sunburn) and preeclampsia. The present invention further provides a combination of pharmacologically active agents and a pharmaceutical composition.
本发明提供了一种生物共轭物,包括公式I'(SEQ ID NO:1)的合成多肽或其酰胺、酯或盐,其中X1、X2、X3、X4、X5、X6、X7、X8、X9、X10、X11、X12和X13在此定义,并且具有半衰期延长基团,其中肽和半衰期延长基团通过连接剂或融合共价连接,可选地。这些多肽是APJ受体的激动剂。本发明还涉及一种制造该生物共轭物的方法,以及其治疗用途,例如治疗或预防急性失代偿性心力衰竭(ADHF)、慢性心力衰竭、肺动脉高压、心房颤动、Brugada综合征、室性心动过速、动脉粥样硬化、高血压、再狭窄、缺血性心血管疾病、心肌病、心脏纤维化、心律失常、水潴留、糖尿病(包括妊娠糖尿病)、肥胖症、外周动脉疾病、脑血管意外、短暂性脑缺血发作、创伤性脑损伤、肌萎缩性侧索硬化、烧伤(包括晒伤)和妊娠高血压。本发明还提供了药理活性剂的组合和制药组合物。
