爆火的GLP-1到底是什么?和司美格鲁肽是什么关系?别再听外行瞎说了
GLP1减重宝典· 2025-10-03 03:50
整理 | GLP1减重宝典内容团队 ▍ 什么是GLP-1? 胰高血糖素样肽 1 ( GLP-1 ) 是一种长 30 或 31 个氨基酸的肽激素,源自胰高血糖素原肽的组织特异性翻译后加工。它由肠道肠内分泌 L 细胞和脑干孤束核内的某些神经元在进食后产生和分泌。初始产物 GLP-1 (1–37) 易受酰胺化和蛋白水解酶裂解,从而产生两种截短且 等效的生物活性形式,GLP-1 (7–36) 酰胺和 GLP-1 (7–37)。活性 GLP-1蛋白二级结构包括来自氨基酸位置 13–20 和 24–35 的两个α-螺 旋,它们由连接区隔开。 GLP-1 与葡萄糖依赖性促胰岛素肽(GIP)一样,是一种 肠促胰岛素 ;因此,它能够通过增强胰岛素的分泌,以葡萄糖依赖的方式降低血 糖水平。除了促胰岛素作用外,GLP-1 还具有多种调节和保护作用。与 GIP 不同,GLP-1 的作用在2 型糖尿病患者中得以保留。胰高血 糖素样肽-1 受体激动剂自 2000 年代起获得批准,用于治疗糖尿病和肥胖症。 内源性 GLP-1 主要被二肽基肽酶 4 (DPP-4) 以及中性内肽酶 24.11 (NEP 24.11) 和肾脏清除快速降解,导致 ...

Core Insights - The FDA issued over 50 warning letters to various companies involved in the formulation or manufacturing of GLP-1 drugs, specifically semaglutide and tirzepatide, primarily due to misleading claims regarding their products [4][6] - The FDA emphasized that these compounded drugs are not equivalent to FDA-approved versions and do not undergo the same safety, efficacy, or quality evaluations [4][6] Regulatory Concerns - The warnings addressed claims that compounded formulations are "generic versions" or contain the "same active ingredient" as FDA-approved GLP-1 drugs, which the FDA deemed false or misleading [4] - Companies must respond within 15 business days with a corrective action plan or reasonable explanation, or they may face further enforcement actions, including product seizures or bans [6] Market Implications - As demand for GLP-1 therapies for obesity and type 2 diabetes treatment surges, the FDA is reinforcing its regulatory requirements in this competitive market [6] - Companies involved in GLP-1 drug compounding need to reassess their labeling, advertising, and promotional strategies to avoid potential legal issues [6]
Nature:“为什么瘦身总是如此艰难,坚持更不容易?原来肥胖还会形成‘记忆’!”

整理 | GLP1减重宝典内容团队 近年来,关于新型基于肠促胰岛素类药物(如司美格鲁肽等单重激动剂)和替尔泊肽等双重激动剂的治疗效果,激起了人们的广泛关 注。这些药物通过靶向胰高血糖素样肽-1(GLP-1)受体和葡萄糖依赖性胰岛素分泌多肽(GIP)受体,正在成为治疗肥胖和2型糖尿 病的有效手段。如今,数十亿美元的投资正加速推动更有效、更少副作用的新型抗肥胖药物的研发。 然而,兴奋的焦点并不仅仅局限于现有的单重激动剂和双重激动剂。近日,在奥地利维也纳举办的欧洲糖尿病研究学会年会上,来自 德国慕尼黑赫尔姆霍兹糖尿病与肥胖研究所的丹妮拉·利斯基维茨博士等研究人员讨论了一种创新的新型五重激动剂。 该五重激动剂结合了GLP-1R和GIPR激动剂,并与拉尼非普诺(lamifibranor)分子结合,这种分子能激活三种不同的过氧化物酶体增 殖物激活受体(PPARs)——PPAR-α、PPAR-δ和PPAR-γ,这三种受体均在能量调节中发挥重要作用。因此,这种新型化合物总共包 含五种激动剂。 在会议上,利斯基维茨博士分享了关于GLP-1R/GIPR/全PPAR五重激动剂的最新研发进展,并强调其在治疗肥胖相关代谢性疾病中的 潜 ...

Core Viewpoint - The article discusses the safety and recommendations regarding the use of GLP-1 medications during pregnancy and breastfeeding, highlighting the need for caution and further research in this area [4][6][12]. Summary by Sections GLP-1 Medications and Pregnancy - GLP-1 receptor agonists, such as Ozempic (semaglutide) and Trulicity (dulaglutide), are increasingly used for treating type 2 diabetes and weight management, but their safety during pregnancy is uncertain [4]. - Experts recommend that women stop or delay the use of GLP-1 medications if they are pregnant or planning to become pregnant [6]. Research on GLP-1 Use During Pregnancy - A large study published in January 2024 in JAMA Internal Medicine tracked around 50,000 children born to mothers with type 2 diabetes who used GLP-1 or insulin during early pregnancy, finding no increased risk of congenital defects compared to insulin use [7]. - Another study in 2023 reviewed 39 independent studies and suggested that GLP-1 use might affect fetal weight and growth, recommending avoidance during pregnancy due to limited human data [8]. Risks Associated with GLP-1 Use During Pregnancy - Potential risks of GLP-1 medications during pregnancy include miscarriage, low birth weight, and congenital defects, primarily based on animal studies [9]. - Current evidence suggests minimal risk if GLP-1 is used in early pregnancy, but healthcare providers may recommend switching to safer alternatives [9]. Recommendations for Women Planning Pregnancy - It is advised to stop using GLP-1 medications at least two months before attempting to conceive, along with adopting healthy lifestyle measures [11]. - The CDC recommends additional preconception measures for women with diabetes to increase the chances of a healthy pregnancy [11]. Breastfeeding and GLP-1 Medications - There is insufficient research on the safety of GLP-1 medications during breastfeeding, and current recommendations suggest avoiding their use during this period [12].
新研究揭示肥胖隐藏诱因:为何"少吃多动"效果有限?
GLP1减重宝典· 2025-10-02 15:05
肥胖已成为21世纪最严峻的全球公共卫生危机之一,其蔓延速度令人震惊。据世界卫生组织最新统计,过去半个世纪全球超重人口激增 近三倍,这一数字仍在持续攀升。 传统观点将肥胖简单归结为能量失衡——即"摄入过多而消耗不足",这种理论主导了数十年的肥胖防治策略。然而,国际知名代谢研究 专家Ba r ba r a E. Co r ke y教授的最新研究发现,肥胖的成因远比我们想象的复杂。她的突破性研究指出,现代饮食中普遍存在的食品添 加剂、环境内分泌干扰物等因素,可能正在悄然改变人体的代谢调控机制。 这些隐藏在日常生活背后的"代谢干扰因子",正以我们尚未完全理解的方式,重塑着人类的能量代谢平衡系统。这一理论为理解全球肥 胖流行提供了全新视角,也解释了为何单纯依靠"少吃多动"往往难以取得理想效果。 随着研究的深入,科学家们逐渐意识到,对抗肥胖需要从更宏观的环境因素和更微观的分子机制双重维度着手。这场关乎人类健康的持 久战,正在揭开其复杂性的冰山一角。 ▍"少吃多动"失效之谜:科学家揭开肥胖背后的隐形推手 长期以来,"管住嘴、迈开腿"被视为对抗肥胖的金科玉律,但越来越多的人发现,即便严格控制饮食、坚持运动,体重仍难以有效下 ...
