Amylin, a member of the calcitonin family, acts via amylin receptors in the hindbrain and hypothalamus to suppress appetite. Native ligands of these receptors are peptides with short half-lives. Conjugating fatty acids to these peptides can increase their half-lives. The long-acting human amylin analog, NN1213, was generated from structure–activity efforts optimizing solubility, stability, receptor affinity, and selectivity, as well as in vivo potency and clearance. In both rats and dogs, a single dose of NN1213 reduced appetite in a dose-dependent manner and with a long duration of action. Consistent with the effect on appetite, studies in obese rats demonstrated that daily NN1213 dosing resulted in a dose-dependent reduction in body weight over a 21-day period. Magnetic resonance imaging indicated that this was primarily driven by loss of fat mass. Based on these data, NN1213 could be considered an attractive option for weight management in the clinical setting.

NN1213 – 一种有效、长效、选择性的人胰淀素类似物



胰淀素是降钙素家族的成员,通过后脑和下丘脑中的胰淀素受体发挥作用,抑制食欲。这些受体的天然配体是半衰期短的肽。将脂肪酸与这些肽结合可以延长它们的半衰期。长效人胰岛淀粉样多肽类似物 NN1213 是通过优化溶解度、稳定性、受体亲和力和选择性以及体内效力和清除率的结构-活性努力而产生的。在大鼠和狗中,单剂量的 NN1213 以剂量依赖性方式降低食欲,且作用持续时间较长。与对食欲的影响一致,对肥胖大鼠的研究表明,每天服用 NN1213 会导致体重在 21 天内呈剂量依赖性下降。磁共振成像表明,这主要是由脂肪量减少引起的。基于这些数据,NN1213 可以被认为是临床环境中体重管理的一个有吸引力的选择。
