0.63mg/ml
(1.66mM)
Taking the 1 mL working solution as an example, add 50 μL of 12.6 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results.
* <1 mg/ml means slightly soluble or insoluble. * Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations. * Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity
Description
MKC3946 is a potent and soluble IRE1α endoribonuclease domain inhibitor which triggered modest growth inhibition in multiple myeloma cell lines, without toxicity in normal mononuclear cells.
Targets
IRE1α endoribonuclease
In vitro
MKC-3946 triggers modest growth inhibition in MM cell lines, without toxicity in normal mononuclear cells. Importantly, it significantly enhances cytotoxicity induced by bortezomib or 17-AAG, even in the presence of bone marrow stromal cells or exogenous IL-6. Both bortezomib and 17-AAG induce ER stress, evidenced by induction of XBP1s, which is blocked by this compound. Apoptosis induced by these agents is enhanced by this chemical, associated with increased CHOP. This compound treatment does not inhibit IRE1α kinase function or binding of activated IRE1α to TRAF2 and downstream JNK signalling.
In Vivo
MKC-3946 inhibits XBP1 splicing in a model of ER stress in vivo, associated with significant growth inhibition of MM cells.
RPMI 8226 cells are treated with or without Tm (5 μg/mL) in combination with MKC-3946 (0-10μM) for 3 hours. Total RNA is extracted; XBP1 and β-actin mRNA are evaluated by RT-PCR.
