The invention relates to analogs of 4-hydroxyisoleucine, and to lactones, pharmaceutically acceptable salts, and prodrugs thereof, to processes for their preparation, and to pharmaceutical compositions comprising the same. The analogs of the invention stimulate both glucose uptake and insulin secretion, and may thus be useful for the prevention and treatment of disorders of carbohydrate or lipid metabolism, including diabetes mellitus (type 1 and type 2 diabetes), pre-diabetes, and Metabolic Syndrome.

Glucagon-likepeptide-1 (GLP-1) signaling is an established therapeutic target for type 2 diabetes mellitus (T2DM). We developed a 7-step synthesis of N55, a positive modulator of GLP-1 signaling isolated from fenugreek (Trigonella foenum-graecum) seeds, with 29% overall yield, and we determined the absolute structure of N55 to be N-((3R,4R,5S)-4,5-dimethyl-2-oxotetrahydrofur-3-yl)linoleic amide.
胰高血糖素样肽-1 (GLP-1) 信号传导是 2 型糖尿病 (T2DM) 的既定治疗靶点。我们开发了N55的 7 步合成,这是从葫芦巴 ( Trigonella foenum-graecum ) 种子中分离的 GLP-1 信号的正调节剂,总产率为 29%,我们确定N55的绝对结构为N -((3 R ,4 R ,5 S )-4,5-二甲基-2-氧代四氢呋喃-3-基)亚油酰胺。
