Biological Activity
| Targets | ATM 1.0 nM (IC50) |
| ln Vitro | In SW620 and HCT116 cells, A011(compound 8d)(10, 30, 100 nM; 5 days) enhances the sensitivity to CPT-11(100 nM)[1]. When coupled with CPT-11, A011 (0-100 nM; 24, 72 h) can cause cell apoptosis and cell cycle arrest in the G2/M phase [1]. Under 1.5 or 3 Gy irradiation, A011(3, 9, 27, 83, 250 nM) dose-dependently lowers the expression of p-ATM and p-Chk2 in SW620 cells[1]. |
| ln Vivo | In mice, A011 (5 mg/kg; intraperitoneal injection; once daily for 23 days) and CPT-11 (5 mg/kg; intraperitoneal injection; once weekly) had anticancer efficacy [1]. |
| Cell Assay |
Cell Proliferation Assay[1] Cell Types: SW620, HCT116 cells Tested Concentrations: 10, 30, 100 nM Incubation Duration: 5 days Experimental Results: Increased the sensitivity of SW620 and HCT116 cells to CPT-11(100 nM). Cell Cycle Analysis[1] Cell Types: SW620, HCT116 cells Tested Concentrations: 0-100 nM Incubation Duration: 24 h Experimental Results: Dose-dependent increased in G2/M arrest was noted when A011 was combined with CPT-11 in SW620 and HCT116 cells. Apoptosis Analysis[1] Cell Types: SW620, HCT116 cells Tested Concentrations: 0-100 nM Incubation Duration: 72 h Experimental Results: Dramatically increased the apoptotic cell populations when combined with CPT-11. Western Blot Analysis[1] Cell Types: SW620, HCT116 cells Tested Concentrations: 3, 10, 30 nM Incubation Duration: 24 h Experimental Results: decreased the expression of p-Chk2 when combined with CPT-11. |
| Animal Protocol |
Animal/Disease Models: Female nude mice (SW620 tumor xenograft model)[1] Doses: 5 mg/kg; CPT-11 (5 mg/kg, ip; once a week) Route of Administration: Ip; one time/day for 23 days Experimental Results: Increased the antitumor activity of CPT-11. |

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.) |
