Taking the 1 mL working solution as an example, add 50 μL of 15 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

MCU-i4 is a negative modulator of the mitochondrial calcium uniporter (MCU) complex that directly binds a specific cleft in MICU1 and decreases mitochondrial Ca2+ influx.

Targets

MCU1 ^[1]

In vitro

MCU-i4 decreases mitochondrial Ca2+ influx. Docking simulations reveal that MCU-i4 directly binds a specific cleft in MICU1, a key element of the MCU complex that controls channel gating. Accordingly, in MICU1-silenced or deleted cells, the inhibitory effect of MCU-i4 is lost. Moreover, MCU-i4 fails to inhibit mitochondrial Ca2+ uptake in cells expressing a MICU1 mutated in the critical amino acids that forge the predicted binding cleft.^[1]

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines C2C12 myoblasts Concentrations 10 μM Incubation Time 24 h Method Growing medium of 90% confluent C2C12 myoblasts is replaced with DMEM containing 2%-heat inactivated horse serum (HS) (differentiation medium). Five days later, cells are incubated for 24 h with MCU-i4 (10 μM) or with DMSO alone (0.1% v/v). At the end of the experiment, myotubes images are taken and myotubes width is measured by means of ImageJ software.
