利拉鲁肽(Liraglutide)是一种长效的胰高血糖素样肽-1(GLP-1)受体激动剂,是GLP-1 (7-37)的合成衍生物含有一个棕榈酸基团[1]。表达人GLP-1受体的CHO细胞内利拉鲁肽能够提高cAMP累积(EC50=61 pM)。体外原代新生大鼠胰岛β-细胞利拉鲁肽(100-1000 nM)能够抑制细胞因子和游离脂肪酸诱导的凋亡,分别超过95%和50%,这一效应会被GLP-1受体拮抗剂exendin-3 (9-39)和PI3K抑制剂渥曼青霉素所阻断[2]。补充膳食诱导的大鼠肥胖模型中,利拉鲁肽(0.2mg/kg,皮下注射,一天两次)降低卡路里摄取,改变饮食偏好到更高的食物与糖果比例,逆转体重和脂肪增加,以及增高胰岛素敏感性[3]。含利拉鲁肽的配方可用作辅助药物来治疗II型糖尿病,以及用于超重或肥胖成人的慢性体重控制。

体内研究:

动物模型(Animal Model):Sprague-Dawley female rats

给药剂量(Dosages):After the initial 12 weeks, the candy-fed (DIO) rats were further randomized into treatment groups for another 12 weeks: 1) liraglutide 0.2 mg/kg s.c. twice daily (n = 10), 2) vildagliptin 10 mg/kg twice daily orally (n = 10), 3) control vehicle twice daily subcutaneously (n = 7), 4) control vehicle twice daily orally (n = 7), and 5) DIO-Chow (candy excluded from diet, reverting to chow only) plus vehicle twice daily orally (n = 10).

体内研究:

动物模型(Animal Model):Human islets transplanted into the anterior chamber of the eye of streptozotocin (STZ)-induced diabetic nude mice.

药物配制(Preparation):A 1000x stock solution was prepared by dissolving 18 mg in 1 ml of sterile normal saline solution (0.9% sodium chloride), divided in single-use aliquots, and stored at−20°C.

注射剂量(Dosages):Nonfasting glycemia before and ~35 days after human islet intraocular transplantation in diabetic nude mice treated with liraglutide (300 μg/kg/day s.c.) or saline (control). Daily liraglutide or saline treatments were started two days prior to transplantation (n = 14 mice/treatment).
