Taking the 1 mL working solution as an example, add 50 μL of 100 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 make it clear; 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

AZD5991 is a macrocyclic MCL-1 inhibitor with sub-nanomolar affinity for MCL-1 (Ki = 0.13 nM). The binding affinity of AZD5991 is about 25-fold lower for mouse Mcl-1 vs. human Mcl-1 but only four-fold lower for rat Mcl-1.

Targets

Mcl-1 ^[2] (Cell-free assay)	Mcl-1 ^[1] (Cell-free assay)
0.13 nM(Ki)	0.7 nM

In vitro

AZD5991 is a potent and direct inhibitor of Mcl-1 with high selectivity versus other Bcl-2 family proteins. AZD5991 binds directly to Mcl-1 and induces rapid apoptosis in cancer cells, most notably myeloma and acute myeloid leukemia (GI50 < 100nM), by activating the Bak-dependent mitochondrial apoptotic pathway. In a panel of cancer-derived cell lines of hematological or solid tumor origin, AZD5991 preferentially kills hematological cells^[1]^[3].

In vivo

AZD5991 shows potent antitumor activity in vivo with complete tumor regression in several models of multiple myeloma and acute myeloid leukemia after a single tolerated dose as monotherapy or in combination with venetoclax. In these in vivo studies, the cytotoxic activity of AZD5991 tightly correlates with induction of the mitochondrial apoptotic pathway as evidenced by cleavage of caspase-3 and PARP^[1].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines MOLP-8 cells Concentrations 0-500 nM Incubation Time 30 min Method MOLP-8 cells are treated with AZD5991 or DMSO ontrol for 30 min. Then samples are centrifuged and pellet resuspended in ice-cold lysis buffer and incubated for 20 min on ice with vortexing every 5 min. Next, samples are centrifuged and protein concentration was assessed. Samples are pre-cleared for 30 min using rotation at 4 °C with 50% slurry of Protein A/G magnetic beads followed by incubation with anti-Mcl-1 antibody overnight at 4 °C with rotation. Protein A/G magnetic beads are then added for 1 h at 4 °C with rotation. Beads are washed four times with lysis buffer / PBS (1:1), then 10% sample reducing agent is added to each IP pellet followed by western blotting analysis.
