KB528 (0-1 μM; 24-72 h) selectively induced apoptosis in MM1.S cells in a concentration-dependent manner after 48 hours of treatment [1]. KB528 (100 nM; 6-24 h) induced a rapid decrease in the acetylation level of IKZF3 protein in MM1.S cells, followed by a brief decrease in mRNA level, then a decrease in protein level, and finally a rebound in mRNA level.

Apoptosis analysis [1]
Cell Types: MM1.S cells Tested Concentrations: 0.1, 1 and 10 μM Incubation Duration: 24, 48 and 72 hours Experimental Results: Cell cycle arrest was induced in the first 24 hours of treatment, followed by apoptosis. RT-PCR[1] Cell Types: MM1.S cells Tested Concentrations: 100 nM Incubation Duration: 24 hours Experimental Results: It can effectively and almost completely downregulate the mRNA of IRF4 and its target genes, while the inhibitory effect on IKZF1 and IKZF3 is relatively weak. Western Blot Analysis [1] Cell Types: MM1.S cells Tested Concentrations: 100 nM Incubation Duration: 6 and 14 hours Experimental Results: MYC, IRF4 and IKZF3 protein levels were significantly reduced. Notably, the loss of IKZF3 protein was more significant than the reduction in its mRNA. |

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).

Oral Formulation 3: Dissolved in PEG400 (Please use freshly prepared in vivo formulations for optimal results.) |
| Preparing Stock Solutions | 1 mg | 5 mg | 10 mg | |
| 1 mM | 2.1526 mL | 10.7629 mL | 21.5257 mL | |
| 5 mM | 0.4305 mL | 2.1526 mL | 4.3051 mL | |
| 10 mM | 0.2153 mL | 1.0763 mL | 2.1526 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.
