MKI-3 is a selective microtubule-associated serine/threonine kinase-like ( MASTL ) inhibitor with an IC50 of 5.72 nM and a K d of 1.89 nM.
Products are for research use only. Not for human use. We do not sell to patients.
Cas No.: 3084702-28-0
Sample solution is provided at 25 µL, 10mM.
In Vivo, MKI-3 (8 mg/kg; i.p.; daily; 2 weeks) significantly reduces tumor growth in a 4T1 triple-negative breast cancer mouse model, induces mitotic cell death, and suppresses the MASTL−ENSA−Aurora A signaling pathway[1].
In Vitro, MKI-3 inhibits cellular MASTL activity with an IC50 of 114.9 nM[1]. MKI-3 (72 h) inhibits proliferation of breast cancer cell lines 4T1, MCF7, MDA-MB-231, and BT549 with IC50 values of 42.01 nM, 93.61 nM, 91.44 nM, and 160.9 nM, respectively[1]. MKI-3 (250 nM; 12 h) suppresses the MASTL-ENSA-Aurora A signaling axis, inducing apoptotic markers, in BT549 and 4T1 breast cancer cells[1]. MKI-3 (250 nM; 24 h) activates PP2A in BT549 breast cancer cells[1]. MKI-3 (250 nM; 24 h) induces mitotic defects including aberrant nuclear morphology, multipolar spindles, and centrosome abnormalities in BT549 breast cancer cells[1]. MKI-3 (250 nM; 48 h) antiproliferative activity in BT549 breast cancer cells is mediated in part by PP2A activation, as co-treatment with 20 nM okadaic acid rescues cell viability[1].

Step 1: Enter information below (Recommended: An additional animal making an allowance for loss during the experiment)
Step 2: Enter the in vivo formulation (This is only the calculator, not formulation. Please contact us first if there is no in vivo formulation at the solubility Section.)
Calculation results:
Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid 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 master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL saline, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
