Biological Activity
| Targets | Aurora A 6.5 μM (IC50, [1]) |
| ln Vitro | AurkA allosteric-IN-1 (100 μM; 48 h) differentially induced cell cycle arrest in different cell types, including lung cancer cell lines and colorectal cancer cell lines[1]. AurkA allosteric-IN-1 (20 μM; 48 h) downregulated the level of phospho-histone H3 in cancer cells[1]. AurkA allosteric-IN-1 (25-400 μM; 48 h) exhibited significant antiproliferative activity against HeLa cells and had a synergistic effect with PHA-767491 (HY-13461), further amplifying its antiproliferative activity[1]. Cell Cycle Analysis[1] Cell Line: HeLa and Panc-1 cells, Lung cancer cell lines (A549 and H358), and colon cancer cell lines (HT29 and HCT116) Concentration: 20 μM Incubation Time: 12, 24, and 48 h Result: Arrested cell cycle at G1/S transition in lung cancer cell lines (A549 and H358), and arrested cell cycle at G2/M in colon cancer cell lines (HT29 and HCT116). Almostly unaffected HeLa and Panc-1 cells. |
| Cell Assay |
Western Blot Analysis[1] Cell Types: HT29 and HCT116 Tested Concentrations: 20 μM Incubation Duration: 48 h Experimental Results: Sharply downregulated the level of phospho-histone H3 (Ser10). Cell Cytotoxicity Assay[1] Cell Types: HeLa Tested Concentrations: 25 μM, 50 μM, 100 μM, 200 μM, and 400 μM Incubation Duration: 12, 24, and 48 h; with or without PHA-767491 Experimental Results: With PHA-767491 sensitized HeLa cells, significantly augmented anti-proliferative activity GI50: 71.7 μM to GI50: 14.0 μM by co-treatment of 1.5 μM PHA-76749. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *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. Injection Formulation 5: 2-Hydroxypropyl-β-cyclodextrin : Saline = 50 : 50 (i.e. 500 μL 2-Hydroxypropyl-β-cyclodextrin → 500 μL Saline) Injection Formulation 6: DMSO : PEG300 : castor oil : Saline = 5 : 10 : 20 : 65 (i.e. 50 μL DMSO → 100 μLPEG300 → 200 μL castor oil → 650 μL Saline) Injection Formulation 7: Ethanol : Cremophor : Saline = 10： 10 : 80 (i.e. 100 μL Ethanol → 100 μL Cremophor → 800 μL Saline) Injection Formulation 8: Dissolve in Cremophor/Ethanol (50 : 50), then diluted by Saline Injection Formulation 9: EtOH : Corn oil = 10 : 90 (i.e. 100 μL EtOH → 900 μL Corn oil) Injection Formulation 10: EtOH : PEG300：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL EtOH → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Oral Formulations Oral Formulation 1: Suspend in 0.5% CMC Na (carboxymethylcellulose sodium) Oral Formulation 2: Suspend in 0.5% Carboxymethyl cellulose Example: Take the Oral Formulation 1 (Suspend in 0.5% CMC Na) as an example, if 100 mL of 2.5 mg/mL working solution is to be prepared, you can first prepare 0.5% CMC Na solution by measuring 0.5 g CMC Na and dissolve it in 100 mL ddH2O to obtain a clear solution; then add 250 mg of the product to 100 mL 0.5% CMC Na solution, to make the suspension solution (2.5 mg/mL, ready for use in animals). Oral Formulation 3: Dissolved in PEG400 Oral Formulation 4: Suspend in 0.2% Carboxymethyl cellulose Oral Formulation 5: Dissolve in 0.25% Tween 80 and 0.5% Carboxymethyl cellulose Oral Formulation 6: Mixing with food powders Note: Please be aware that the above formulations are for reference only. InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently. (Please use freshly prepared in vivo formulations for optimal results.) |
