Biological Activity
| ln Vivo | Oral gavage of 100 mg/kg of icosalbutanil produced portal plasma flow rates (522 mL/h) that were significantly higher than mesenteric lymph fluid flow rates (0.5 mL/h). This suggests that icosalbutanol is almost entirely absorbed via the lymphatic route through the portal vein (>99%) in 8-week-old male Wistar rats [1]. Icosalbutanil ([14-C]-Icosalbutanil; oral gavage; 100 mg/kg; once) demonstrated peak radioactivity concentrations in most tissues 4–8 hours after administration (radiactivity levels in most other tissues are lower than those in the plasma of male albino Wistar rats [1]). Icosalbutinate (dietary administration; 135 mg/kg/day; 5 weeks) significantly improved glucose tolerance following oral glucose loading, significantly reducing AUC (0–120 min) by 60%, without affecting body weight, and lowering Plasma alanine aminotransferase (ALT) levels improve glucose metabolism by significantly lowering blood glucose, hemoglobin A1c, plasma insulin, and HOMA-IR in mice (-50%, -47%, -76%, and -87%, respectively) [ 1”. Oral icoxabutate (112 mg/kg/day; 20 weeks) inhibited hepatocellular hypertrophy (-82%) and microvesicular steatosis (-35%) but not macrovesicular steatosis. Despite a similar decrease in liver inflammatory cell aggregates, only icosabutate decreased the amount of liver collagen after 20 weeks of treatment [1]. |
| Animal Protocol |
Animal/Disease Models: 6-8 weeks old male ob/ob mice [1] Doses: 135 mg/kg Route of Administration: 135 mg/kg/day, administered through diet; 5-week Experimental Results: Improved glucose metabolism and insulin resistance. Animal/Disease Models: 8-15 weeks old male APOE*3 Leiden.CETP mice, fed a high-fat and high-cholesterol diet [1] Doses: 112 mg/kg/day Route of Administration: po (oral gavage); 20-week Experimental Results: Improved microbiome Alveolar steatosis, liver inflammation, and fibrosis. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~266.98 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.67 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 2.5 mg/mL (6.67 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 3: ≥ 2.5 mg/mL (6.67 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
