KD: 28.77 μM (Skp2)[1]
|
---|---|
ln Vitro |
Skp2 can be directly bound by SCFSkp2-IN-2 (Compound AAA-237) (0.3-3 μM; 24-72 h), which will cause the proteasome to break down Skp2. In NSCLC cells, AAA-237 has a time-dependent inhibitory effect on Skp2 protein expression but no discernible effect on Skp2 mRNA expression [1]. A549 and H1299 cell proliferation is inhibited by SCFSkp2-IN-2 (0.3-3 μM; 24-72 h) in a dose- and time-dependent manner [1]. The G0/G1 checkpoint is where the cell cycle is arrested by SCFSkp2-IN-2 (0.3-3 μM; 24-72 h) because it modulates the PI3K/Akt-FOXO1 and Skp2-Cip/Kip signaling pathways [1]. A549 and H1299 cells undergo apoptosis when exposed to SCFSkp2-IN-2 (0.3-3 μM; 24-72 h) in a dose- and time-dependent manner [1]. In NSCLC cells, SCFSkp2-IN-2 (0.3 μM; 1–7 days) causes senescence [1].

ln Vivo |
In a lung cancer A549 xenograft mice model, SCFSkp2-IN-2 (Compound AAA-237) (15 or 45 mg/kg; ip; daily for 14 days) exhibits anti-tumor efficacy[1].

Western Blot Analysis[1]
Cell Types: A549 and H1299 cells Tested Concentrations: 0.3, 1 and 3 μM Incubation Duration: 24, 48 and 72 h Experimental Results: Increased the expression levels of p21Cip1 and p27Kip1. diminished the level of Skp2. diminished the expression levels of CDK2, p-CDK2, cyclin E1, CDK4, p-CDK4 and cyclin D. Increased the levels of cleaved PARP, cleaved caspase 3, cleaved caspase 9 and Bax. diminished the expression of PARP and Bcl-2. Cell Proliferation Assay [1] Cell Types: A549 and H1299 cells Tested Concentrations: 0.3, 1 and 3 μM Incubation Duration: 24, 48 and 72 h Experimental Results: Inhibited the proliferation of A549 and H1299 cells in a dose- and time-dependent manner. The IC50 for A549 was 3 μM at 24 h, 2.5 μM at 48 h and 0.7 μM at 72 h. The IC50 for H1299 was 3.9 μM at 24 h, 1.8 μM at 48 h and 1.1 μM at 72 h. Cell Cycle Analysis[1] Cell Types: A549 and H1299 cells Tested Concentrations: 0.3, 1 and 3 μM Incubation Duration: 24, 48 and 72 h Experimental Results: Arrested the cell cycle at G0/G1 in a dose- and time-dependent manner.

Animal Protocol |
Animal/Disease Models: A549 xenograft model[1]
Doses: 15 or 45 mg/kg Route of Administration: intraperitoneal (ip) administration, daily for 14 days Experimental Results: Dramatically decreased tumor volume and weight. The tumor growth inhibition of the low dose and high dose was 55% and 64%, respectively. No obvious weight loss or abnormal behavior was observed. decreased the expression of Ki67 in tumor tissue. decreased the expression of Skp2 and Bcl-2 and increased the expression of p27, the cleaving of caspase 3, caspase 9, PARP and Bax. |

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
Injection Formulation 1: DMSO : Tween 80: Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *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)] 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).

*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.
