A-205804 (A205804; A 205804) is a novel selective inhibitor of E-selectin and intercellular adhesion molecule-1 (ICAM-1) expression (IC50 = 20 nM and 25 nM) with potential anticancer activity. ICAM1 is a protein associated with diseases such as Malaria and Hepatocellular Carcinoma. In human vascular endothelial cells using whole-cell high-throughput assay, it was shown that A-205804 exhibited potent and selective inhibition to E-selectin and ICAM-1 with low concentrations.
| ln Vitro |
At an IC50 of 152 μM, A-205804 displays cellular toxicity for HUVEC[1]. In an in vitro flow experiment, A-205804 effectively inhibits cell-cell adhesion, indicating its applicability in a model physiological system[1].
|
|---|---|
| ln Vivo |
For rats, A-205804 (5 mg/kg; po) exhibits a half-life of one hour[1]. For two weeks, A-205804 (10 mg/kg; po; three times per week) reduces the expression of E-selectin on the endothelium vascular niche cells in mice[2].

| Animal Protocol |
Animal/Disease Models: C57BL/6 mice[2]
Doses: 10 mg/kg Route of Administration: Oral administration, 3 times per week, for 2 weeks Experimental Results: Efficiently diminished the expression of E -selectin on the endothelial vascular niche cells Animal/Disease Models: Rat[1] Doses: 5 mg/kg (pharmacokinetic/PK Analysis) Route of Administration: Oral administration Experimental Results: t1/2 = 1 hour |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (6.92 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 20.8 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 2: ≥ 2.08 mg/mL (6.92 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 20.8 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.) |

| 10 mM | 0.3329 mL | 1.6644 mL | 3.3289 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
Method for preparing in vivo formulation:：Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
