JAK-2/3-IN-3 (compound ST4j) is a potent JAK2/3 surrogate with IC50s of 13.00 and 14.86 nM for JAK2 and JAK3, respectively. JAK-2/3-IN-3 inhibits JAK2 autophosphorylation and induces cellular effects in a dose- and time-dependent manner. JAK-2/3-IN-3 may be utilized in the study of lymphocyte-derived diseases and leukemia.

Biological Activity


ln Vitro JAK-2/3-IN-3 exhibits negligible toxicity to normal cells and particularly inhibits human erythroleukemia cells (0-100 μM; 72 h) [1]. Human erythroleukemia TF1 cell proliferation is inhibited by JAK-2/3-IN-3 via the JAK2/STAT5 signaling pathway [1]. In TF1 cells, JAK-2/3-IN-3 (15.53 μM; 24, 48, and 72 hours) time-dependently causes apoptosis, which results in cytotoxicity [1]. JAK-2/3-IN-3 (IC25, IC50, IC75; 24 h) dose-dependently induces apoptosis in TF1 cells, resulting in cytotoxicity [1].
Cell Assay Apoptosis analysis [1]
Cell Types: TF1 Cell
Tested Concentrations: 15.53 μM
Incubation Duration: 24, 48, 72 h
Experimental Results: Increased apoptosis by ∼20%, ∼40%, and ∼70% after 24, 48, and 72 h of incubation ,respectively. When the concentrations were IC25, IC50 and IC75, cell apoptosis increased by approximately 15%, 20% and 30% respectively.

Cytotoxicity assay [1]
Cell Types: TF1, HEL, Vero and HepG2 Cell
Tested Concentrations: 0-100 μM
Incubation Duration: 72 h
Experimental Results: Inhibited the growth of TF1 and HEL cells, IC50 were 15.53 and 17.90 μM respectively. Shows low toxicity to normal Vero cells and HepG2 cells (IC50 >100 μM in Vero cells, >50 μM in HepG2 cells).

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.)
