| 动物实验 |
HFD-induced obese mouse model: 6-week-old C57BL/6 mice were fed a high-fat diet (60% kcal from fat) for 12 weeks to induce obesity and metabolic dysfunction. Mice were randomly divided into vehicle and treatment groups. NDI-091143 was suspended in 0.5% carboxymethylcellulose sodium and administered orally at 10, 30, or 100 mg/kg/day for 28 days. Body weight and food intake were monitored weekly. At the end of treatment, serum was collected for lipid and insulin analysis; liver and epididymal fat pads were harvested to measure triglyceride content and histological changes [1]
- Glucose tolerance test (GTT): On day 24 of treatment, mice were fasted for 16 hours, then administered glucose (2 g/kg, intraperitoneal). Blood glucose levels were measured at 0, 15, 30, 60, and 120 minutes post-glucose injection to calculate AUCglucose [1] - Rebound effect assessment: A subset of mice treated with 30 mg/kg/day for 28 days was withdrawn from drug treatment and monitored for additional 7 days. Serum lipids and body weight were measured to evaluate rebound lipid accumulation [1] |
| 药代性质 (ADME/PK) |
Oral bioavailability: 65% (mouse), 71% (rat) [1]
- Plasma half-life (t1/2): 5.8 hours (mouse, oral), 7.2 hours (rat, oral) [1] - Peak plasma concentration (Cmax): 2.3 μg/mL (mouse, 30 mg/kg oral), 3.1 μg/mL (rat, 30 mg/kg oral) [1] - Volume of distribution (Vss): 2.8 L/kg (mouse), 3.5 L/kg (rat) [1] - Clearance (CL): 0.32 L/h/kg (mouse), 0.27 L/h/kg (rat) [1] - Metabolism: Minimally metabolized in the liver (≤15% metabolized after 24 hours); unchanged drug accounts for ~85% of plasma radioactivity [1] - Excretion: ~60% excreted in feces (unchanged drug + metabolites), ~35% in urine (primarily unchanged drug); <5% metabolized to inactive derivatives [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
Acute toxicity: LD50 > 500 mg/kg (oral in mouse and rat); no mortality or overt adverse effects (ataxia, lethargy) at doses up to 500 mg/kg [1]
- Subchronic toxicity: Daily oral administration of 100 mg/kg for 28 days in rats caused no significant changes in liver/kidney function (ALT, AST, creatinine) or hematological parameters [1] - Plasma protein binding rate: ~92% (human), ~90% (mouse), ~91% (rat) [1] - No hepatotoxicity: Liver histopathology showed no inflammation or steatosis in mice treated with 100 mg/kg/day for 28 days [1] |

NDI-091143 is a potent, selective, orally active allosteric inhibitor of human ATP-citrate lyase (ACL) [1]
- Core mechanism of action: Binds to a unique allosteric pocket of ACL, inducing conformational changes that abrogate its catalytic activity without competing with substrates (ATP/citrate); blocks de novo lipid synthesis by reducing acetyl-CoA availability [1] - Potential therapeutic applications: Metabolic disorders including obesity, non-alcoholic fatty liver disease (NAFLD), hyperlipidemia, and type 2 diabetes [1] - Distinguished by high oral bioavailability, long half-life, minimal metabolism, and lack of rebound effects, supporting clinical utility for chronic metabolic disease treatment [1] - Structural advantage: Allosteric binding mode confers higher selectivity vs. orthosteric ACL inhibitors, minimizing off-target metabolic effects [1] |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
