Novel growth hormone conjugates comprising a growth hormone compound (GH) and a growth hormone binding protein (GHBP) are disclosed. The invention also encompasses a novel derivatization method for producing stable, long-lasting conjugate (hGH-GHBP) by site specific conjugation. The novel GH-GHBP conjugates have an extended half-life in circulation that facilitates therapeutic use of the protein. The GH-GHBP conjugates exhibit pharmacological properties such as increased functional in vivo half-life, improved renal filtration, improved protease protection and albumin binding.
揭示了包括生长激素化合物(GH)和生长激素结合蛋白(GHBP)的新型生长激素共轭物。该发明还涵盖了一种用于通过位点特异性结合制备稳定、持久的共轭物(hGH-GHBP)的新型衍生化方法。新型GH-GHBP共轭物在循环中具有延长的半衰期,有助于蛋白质的治疗应用。GH-GHBP共轭物表现出诸如增加的体内功能半衰期、改善的肾脏过滤、改善的蛋白酶保护和结合白蛋白等药理特性。
