体外研究 (In Vitro)
在HepG2细胞中,奥曲肽可逆转棕榈酸(PA)诱导的Akt和GSK3β磷酸化以及GS mRNA表达的改变[1]。奥曲肽(10 mM,6小时)可导致糖原和磷酸化糖原合成酶转换3β(GSK3β)水平升高。
细胞模型:采用人肝母细胞瘤HepG2细胞建立体外脂肪肝模型。将细胞用棕榈酸(PA,125 μM)加0.5% BSA处理24小时,以诱导脂质积累和胰岛素抵抗。加入奥曲肽(10⁻⁸ mmol/L)处理6小时后,再用胰岛素(100 μM)刺激20分钟,然后收集细胞[1]。
- 脂质积累:油红O染色显示,奥曲肽处理显著减轻了PA诱导的HepG2细胞中脂滴的积累。与仅PA组相比,奥曲肽处理组的IOD值显著降低(P<0.01)[1]。
- Akt/GSK3β信号通路:Western blot分析显示,与对照组相比,PA处理显著降低了Akt(降低74.2%)和GSK3β(降低18.7%)的磷酸化水平。奥曲肽治疗显著逆转了这些降低,与PA组相比,p-Akt增加了140.8%,p-GSK3β增加了12.2%(P<0.05)[1]。
- 糖原合成酶mRNA:RT-qPCR分析显示,PA治疗显著降低了GS mRNA水平。与PA组相比,奥曲肽治疗显著提高了GS mRNA的表达(0.940±0.07 vs. 0.60±0.08,P<0.05)[1]。
体内研究 (In Vivo)
在高脂饮食(HFD)动态组中,奥曲肽显著降低了胰岛素浓度。研究发现,奥曲肽显著降低了胰岛素浓度,但对血清甘油三酯(TG)、总胆固醇(TC)、游离脂肪酸(FFA)、丙氨酸氨基转移酶(ALT)或天冬氨酸氨基转移酶(AST)水平无影响。奥曲肽显著抑制了稳态模型评估胰岛素抵抗指数(HOMA-IR)。奥曲肽使腹腔葡萄糖耐量试验(ipGTT)和腹腔胰岛素耐量试验(ipITT)的曲线下面积(AUC)略有降低。在棕榈酸(PA)处理的HepG2细胞中,奥曲肽减少了HFD细胞引起的脂肪变性及脂滴积累。在HFD脂肪沉积中,奥曲肽刺激Akt和GSK3β的磷酸化以及谷氨酰胺合成酶(GS)mRNA的表达[1]。与对照组(CONT)相比,奥曲肽还降低了体重和湿肾重量。棕榈酸(PAS)和奥曲肽/棕榈酸联合治疗降低了环磷酸腺苷(cAMP)水平,但奥曲肽单独使用并未降低磷脂酰胆碱(PCK)水平。与单独使用PAS组相比,奥曲肽/PAS组中pS6阳性细胞的数量显著降低[2]。动物模型:雄性Sprague-Dawley大鼠(3周龄,40-60 g)喂食高脂饮食(HFD,500 kcal/100 g,60%热量来自脂肪)24周以诱导肥胖。选择体重≥对照组1.4倍的大鼠。将肥胖大鼠分为HFD对照组(n=12)和奥曲肽治疗组(n=12)。在继续高脂饮食喂养期间,每 12 小时皮下注射一次奥曲肽,剂量为 40 μg/kg 体重,持续 8 天 [1]。

- 血糖和胰岛素:奥曲肽显著降低了空腹血糖(HFD 组为 6.26±1.55 mmol/L,奥曲肽 组为 4.75±1.60 mmol/L,P<0.01)和血清胰岛素水平(157.68±43.55 mmol/L vs. 108.85±66.36 mmol/L,P<0.05)[1]

- 胰岛素敏感性:胰岛素抵抗指标 HOMA 指数经奥曲肽治疗后显著降低(HFD 组为 39.57±13.48,奥曲肽 组为 23.40±16.71,P<0.05)[1] P<0.01),表明胰岛素敏感性改善[1]

- 葡萄糖和胰岛素耐量试验:ipGTT 和 ipITT 显示,与 HFD 组相比,奥曲肽 治疗分别使曲线下面积 (AUC) 降低了 5.2% 和 10.5%,但这些变化未达到统计学意义[1]

- 血脂和肝酶:与 HFD 组相比,奥曲肽 治疗降低了血清甘油三酯 (TG)、总胆固醇 (TC)、游离脂肪酸 (FFA)、丙氨酸氨基转移酶 (ALT) 和天冬氨酸氨基转移酶 (AST) 水平,但这些变化未达到统计学意义[1]

- 肝脏脂质含量:奥曲肽 显著降低了肝脏甘油三酯 (TG) 水平(HFD 组为 29.94±14.63 mg/g 肝脏,而 18.11±7.08 mg/g 肝脏) 奥曲肽组,P<0.01)和肝脏游离脂肪酸(FFA)水平(61.22±16.04 mmol/g 蛋白 vs. 40.86±5.09 mmol/g 蛋白,P<0.01)[1]

- 肝糖原含量:奥曲肽显著增加肝糖原含量(HFD 组为 3.66±0.84 mg/g 蛋白,奥曲肽组为 4.77±0.78 mg/g 蛋白,P<0.05)[1]

- 肝脂肪变性:肝组织 H&E 染色和油红 O 染色显示,奥曲肽 治疗显著改善了 HFD 诱导的肝脂肪变性,减少了脂肪沉积和脂质浸润。与高脂饮食组(HFD组)相比,奥曲肽组的油红O染色积分光密度(IOD)值显著降低(P<0.01)[1]。
-肝脏中的Akt/GSK3β信号通路:Western blot分析显示,与高脂饮食组相比,奥曲肽治疗显著增加了肝组织中Akt(Ser473)和GSK3β(Ser9)的磷酸化水平(P<0.05)。奥曲肽治疗也显著提高了GS mRNA水平(P<0.05)[1]。

药代性质 (ADME/PK)
吸收、分布和排泄
奥曲肽皮下注射后可完全吸收。口服缓释胶囊后,峰浓度比皮下注射后低33%。口服给药后的Cmax为1.67-2.5小时,而皮下注射后仅为30分钟。肢端肥大症患者每日两次,每次20 mg时,峰浓度为2.5 mg/nL;每日两次,每次40 mg时,峰浓度为5.30 ng/mL。无论给药途径如何,AUC均随剂量成比例增加。口服奥曲肽后,约32%经尿液排泄,30-40%经肝脏经粪便排泄。约11%的原形药物残留在尿液中,2%从粪便中排出。一项药代动力学研究显示,健康志愿者体内分布容积为 13.6 L。另一项药代动力学研究显示,健康志愿者静脉给药后的分布容积范围为 18.1 至 30.4 L。奥曲肽的全身清除率为 7–10 L/h。一项药代动力学研究显示,奥曲肽的总清除率为 11.4 L/h。代谢/代谢物:据报道,奥曲肽主要在肝脏代谢。生物半衰期:皮下注射后的血浆半衰期估计为 0.2 小时。皮下给药和口服给药的平均消除半衰期为 2.3 至 2.7 小时,无统计学差异。一项药代动力学研究显示,血浆半衰期为 72 至 113 分钟。
毒性/毒理 (Toxicokinetics/TK)
肝毒性
少数接受奥曲肽治疗的患者可能会出现轻度、短暂且无症状的血清转氨酶水平升高;部分患者的转氨酶水平会持续升高并随时间推移而加重,可能需要停药。此外,已有数例由奥曲肽引起的急性、具有临床意义的肝损伤病例报道。肝损伤通常发生在开始治疗后的1至6个月内,且剂量越高,发生率可能越高。大多数与奥曲肽治疗相关的肝损伤病例无症状且无黄疸,其特征是血清ALT和AST显著升高,而血清碱性磷酸酶、GGT和胆红素水平正常或接近正常。然而,在某些情况下,尤其是在再次给药后,可能会出现黄疸。目前尚无与奥曲肽相关的急性肝衰竭或胆管消失综合征的报道;这种损伤的特点是停用注射或输注后病情迅速好转。已有数例先天性高胰岛素血症新生儿和婴儿接受高剂量奥曲肽持续输注后出现转氨酶水平显著升高的病例报道,停药后转氨酶水平迅速恢复正常。奥曲肽抑制胆囊收缩并减少胆汁分泌,长期治疗与高胆固醇胆结石发生率增加相关。前瞻性研究表明,25%至65%接受奥曲肽维持治疗的肢端肥大症患者会出现胆结石(超声检查发现),其中一些患者会出现症状性胆结石,需要住院治疗和胆囊切除术。即使在胆囊切除术后,胆固醇结石仍可能在胆总管和肝内胆管内形成,引起症状、败血症,甚至需要部分肝切除术。熊去氧胆酸治疗似乎并不能预防奥曲肽治疗期间的胆结石形成,尽管它可能有所帮助。奥曲肽还与急性胰腺炎相关,这可能是由于其对胃肠道激素释放的抑制作用,尽管其他病例可能是由于胆结石排出和胰管阻塞所致。概率评分:C(可能是具有临床意义的肝损伤原因)。
妊娠和哺乳期影响
◉ 哺乳期用药概述
尚未研究奥曲肽是否会分泌到母乳中。然而,由于其分子量高达10¹⁹道尔顿,因此分泌到母乳中的量可能极少。口服吸收不良,但已安全地通过注射直接给药于婴儿,因此不太可能对母乳喂养的婴儿产生不良影响。至少有三名婴儿成功接受母乳喂养,且未报告任何不良反应。在获得更多数据之前,哺乳期妇女应在密切监测婴儿的情况下使用奥曲肽,尤其是在婴儿未满 2 个月的情况下。
◉ 对母乳喂养婴儿的影响
一位母亲在孕期和产后接受了奥曲肽治疗肢端肥大症(剂量未说明)。她母乳喂养婴儿 4 个月(喂养持续时间未说明),未出现任何明显问题。
一位患有肢端肥大症的妇女在产后哺乳期间每 6 周接受一次长效奥曲肽(Zanderidin LAR;剂量未说明)。产后 6 个月,注射频率增加至每 4 周一次。她母乳喂养婴儿 12 个月(喂养持续时间未说明)。该儿童 5 岁时发育正常。
◉ 对母乳喂养和泌乳的影响
一位患有肢端肥大症的孕妇在妊娠 12 周时开始每月注射 10 mg 长效奥曲肽。分娩后,她继续母乳喂养至产后6周,之后奥曲肽LAR的剂量需要增加至每月20毫克。服用奥曲肽期间,她继续成功进行母乳喂养。
蛋白结合
约65%的剂量与血浆中的脂蛋白和白蛋白结合。
观察到的副作用:在8天的治疗期间,奥曲肽治疗的大鼠表现出正常的活动和进食行为。未观察到明显的不适、腹泻或脂肪泻症状[1]

- 潜在副作用(文献):讨论中提到,奥曲肽的潜在副作用包括胃肠道反应,例如厌食、痉挛、脂肪泻、稀便和腹泻。然而,本研究并未观察到这些现象[1]

药效学
奥曲肽模拟天然激素生长抑素的作用。与生长抑素类似,它能抑制生长激素和胰高血糖素,可用于治疗肢端肥大症患者的组织生长障碍和胰岛素调节紊乱。此外,奥曲肽可通过减少内脏血流量和与腹泻相关的多种胃肠道激素,缓解胃肠道肿瘤引起的潮红和腹泻。产品标签警告称,奥曲肽可能会降低健康志愿者的胆囊收缩力、胆汁分泌和促甲状腺激素 (TSH) 释放。此外,已有接受奥曲肽治疗的患者出现维生素 B12 水平下降的报道。服用奥曲肽的患者应密切监测维生素B12水平。
背景和化学特性:奥曲肽是一种生长抑素类似物,其半衰期比天然生长抑素更长,作用更强。生长抑素是一种神经激素,具有广泛的生物活性,包括减少胰岛素和胰高血糖素的分泌、抑制胃排空和胃酸分泌以及减少肠道对营养物质的吸收[1]

-既往研究:既往研究表明,奥曲肽可促进体重减轻,减少胰岛素过度分泌,并改善高脂饮食诱导肥胖小鼠的代谢异常。它还能改善代谢和氧化应激紊乱[1]。
- 临床应用:在临床医学中,奥曲肽广泛用于治疗急性胰腺炎和胃肠道出血[1]。
- 肝糖原合成的作用机制:奥曲肽通过激活Akt/GSK3β信号通路,改善高脂饮食诱导的肥胖大鼠的肝糖原合成。它增加Akt(Ser473)和GSK3β(Ser9)的磷酸化,导致GSK3β(通常抑制GS)失活,并增加GS mRNA的表达。这导致糖原合成增强、血糖水平降低和胰岛素敏感性提高[1]

- 对肥胖和代谢的双重作用:该研究表明,奥曲肽不仅能降低体重和脂肪含量,还能改善高脂饮食诱导的肥胖大鼠的肝脂肪变性、糖原合成和胰岛素抵抗,提示其在肥胖症及肥胖相关代谢紊乱(包括非酒精性脂肪性肝病)的治疗中具有潜在的应用价值[1]

- 临床意义:作者认为,基于奥曲肽对糖原合成、葡萄糖稳态和肝脂肪变性的有益作用,可将其视为治疗高脂饮食诱导的肥胖症及肥胖相关代谢紊乱的一种新型策略[1]

- 给药信息:奥曲肽以40 μg/kg体重每12小时皮下注射一次。 8 天。体外研究中,浓度为 10⁻⁸ mmol/L [1]

2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL;

3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果,工作液请现配现用!

  • Expression of p-Akt and p-GSK3β protein, and GS mRNA levels in PA-treated HepG2 cells. (A) Western blotting images of p-Akt (Ser473) expression, and (B) quantification of band intensities. The PA group exhibited the lowest protein expression levels of p-Akt among the three groups. (C) Western blotting images of p-GSK3β (Ser9) expression, and (D) quantification of band intensities. The level of p-GSK3β expression in the PA group was lower when compared with the control group. However, octreotide administration inhibited the reduction by promoting GSK3β phosphorylation. (E) The downregulation of GS mRNA in the PA group was ameliorated by octreotide intervention. Data are presented as the mean ± standard deviation of three independent experiments. *P<0.05 vs. the control group; #P<0.05 vs. the PA group. p-Akt, phosphorylated-Akt; p-GSK3β, phosphorylated-glycogen synthase kinase 3β; GS, glycogen synthase; PA, palmitate; HFD, high fat diet; IOD, integrated optical density.[1].Wang XX, et al.
