BMS-687453 对人 PPARα 的 EC50 和 IC50 分别为 10 nM 和 260 nM,在 PPAR-GAL4 反式激活中相对于人 PPARγ 4100 nM 和 >15000 nM 的选择性约为 410 倍和超过 57 倍,BMS-687453 是一种强效选择性药物。 PPARα 激动剂。在 HepG2 细胞中,与 PPARγ (EC50 = 2400 nM) 相比,BMS-687453 显示出约 50 倍的选择性和高 PPARα 效力 (EC50 = 47 nM)。 BMS-687453 在这两个物种中仍然是完全的 PPARα 激动剂,但它在啮齿动物 PPARα 功能测定中表现出较弱的活性,对小鼠的 EC50 适中,为 426 nM,对仓鼠为 488 nM[1]。

| 动物实验 |
Formulated in 2% Tween 80 and 0.5% CMC (carboxymethylcellulose) in 97.5% Gibco distilled water; 5 mL/kg; Oral gavage.
Male 6 8 week old human apoA1 transgenic mice 1. Hyperlipidemia mouse model establishment: Male C57BL/6 mice (6-8 weeks old, 18-22 g) were fed a high-fat diet (45% fat, 20% protein, 35% carbohydrate) for 8 weeks to induce hyperlipidemia. Mice with serum TG > 2.5 mmol/L and LDL-C > 1.5 mmol/L were selected for the experiment [2] 2. Experimental grouping and drug administration: Mice were randomly divided into 5 groups (n=8/group): vehicle control (0.5% carboxymethylcellulose sodium, CMC-Na), BMS-687453 1 mg/kg, BMS-687453 3 mg/kg, BMS-687453 10 mg/kg, and combination group (BMS-687453 3 mg/kg + LXR agonist 1 mg/kg). BMS-687453 was suspended in 0.5% CMC-Na and administered orally by gavage once daily for 14 days. The vehicle group received the same volume of 0.5% CMC-Na [2] 3. Sample collection and analysis: At the end of the experiment, mice were fasted for 12 hours, and blood was collected from the orbital plexus to separate serum for TG, LDL-C, and HDL-C detection using commercial kits. Mice were sacrificed by cervical dislocation, and liver tissues were collected for qRT-PCR analysis of target gene expression. Feces were collected during the last 3 days of treatment to measure cholesterol excretion using a cholesterol assay kit [2] |
| 药代性质 (ADME/PK) |
1. Oral bioavailability: In rats, oral administration of BMS-687453 (10 mg/kg) resulted in an absolute bioavailability of 52% [1]
2. Plasma pharmacokinetics: After oral administration of BMS-687453 (10 mg/kg) in rats, the peak plasma concentration (Cmax) was 2.3 μM, achieved at 1 hour (Tmax), area under the curve (AUC0-24h) was 15.6 μM·h, and elimination half-life (t1/2) was 6.8 hours [1] 3. Tissue distribution: In mice, 2 hours after oral administration of BMS-687453 (10 mg/kg), the highest drug concentration was detected in the liver (5.8 μM), followed by adipose tissue (3.2 μM), plasma (2.1 μM), and kidney (1.7 μM). Brain concentration was undetectable (<0.1 μM) [1] |
| 毒性/毒理 (Toxicokinetics/TK) |
1. Acute toxicity: In rats, single oral administration of BMS-687453 at doses up to 200 mg/kg did not cause significant mortality or obvious toxic symptoms (e.g., lethargy, weight loss, gastrointestinal distress) within 14 days of observation [1]
2. Chronic toxicity: Mice treated with BMS-687453 (10 mg/kg/day, oral) for 28 days showed no significant changes in liver function (ALT, AST) or kidney function (BUN, creatinine) compared to the vehicle group. Histopathological analysis of major organs (liver, kidney, heart, lung) revealed no abnormal lesions [1] |

| 其他信息 |
1. BMS-687453 is a selective peroxisome proliferator-activated receptor α (PPARα) agonist with an oxybenzylglycine scaffold. It activates PPARα by binding to its ligand-binding domain, thereby regulating the expression of genes involved in fatty acid oxidation, triglyceride metabolism, and lipoprotein transport [1]
2. The drug exhibits potent lipid-lowering activity in hyperlipidemic animal models, reducing TG and LDL-C while increasing HDL-C, making it a potential therapeutic agent for dyslipidemia. Its synergistic effect with LXR agonists on cholesterol excretion suggests a promising strategy for combined lipid-lowering therapy [2] 3. BMS-687453 has favorable pharmacokinetic properties, including high oral bioavailability, effective liver targeting (a key organ for lipid metabolism), and low toxicity in preclinical studies, supporting its potential for clinical development [1] 4. The high selectivity for PPARα minimizes off-target effects associated with PPARγ or PPARδ activation (e.g., weight gain, edema), enhancing its safety profile for long-term use in lipid metabolism disorders [1] |
