AZD-5991 (AZD5991) is a novel, potent, rationally designed macrocyclic molecule and selective MCL-1 inhibitor with anticancer activity. With an IC50 of 0.7 nM in the FRET assay and a Kd of 0.17 nM in the surface plasmon resonance (SPR) assay, it inhibits MCL-1. The drug AZD5991, which is currently in clinical development, has a high affinity and selectivity for Mcl-1. By activating the Bak-dependent mitochondrial apoptotic pathway, AZD5991 binds directly to Mcl-1 and causes rapid apoptosis in cancer cells, most notably myeloma and acute myeloid leukemia. After a single well-tolerated dose, AZD5991 exhibits strong antitumor activity in vivo with complete tumor regression in a number of models of multiple myeloma and acute myeloid leukemia when used alone or in combination with bortezomib or venetoclax. A Phase I clinical trial (NCT03218683) has been started to evaluate AZD5991 in patients with hematological malignancies based on these encouraging data.

ln Vitro |
AZD5991 is a potent and direct inhibitor of Mcl-1 with high selectivity versus other Bcl-2 family proteins. Apoptosis is triggered quickly in cancer cells by AZD5991 by binding directly to Mcl-1 and activating the Bak-dependent mitochondrial apoptotic pathway, most notably in myeloma and acute myeloid leukemia (GI50 100nM) cells. Hematological cells are preferentially killed by AZD5991 in a panel of cancer-derived cell lines with hematological or solid tumor origins[1][3].

|
ln Vivo |
After a single well-tolerated dose, AZD5991 exhibits strong antitumor activity in vivo with complete tumor regression in a number of models of multiple myeloma and acute myeloid leukemia when used alone or in combination with bortezomib or venetoclax. As shown by the cleavage of caspase-3 and PARP in these in vivo studies, AZD5991's cytotoxic activity closely correlates with the activation of the mitochondrial apoptotic pathway[1].

Cell Assay |
MOLP-8 cells are treated with AZD5991 or DMSO ontrol for 30 min. The samples are then centrifuged, and the pellet is resuspended in ice-cold lysis buffer and incubated for 20 min.on ice with vortexing every 5 min. After centrifuging the samples, the protein concentration was measured. Before incubating with anti-Mcl-1 antibody overnight at 4 °C with rotation, samples are pre-cleared for 30 min at 4 °C using rotation and a 50% slurry of Protein A/G magnetic beads. After that, Protein A/G magnetic beads are added and rotated for 1 hour at 4 °C. Each IP pellet is given a 10% sample reducing agent addition before being washed four times with lysis buffer/PBS (1:1) and then being subjected to a western blotting analysis.

Additional Infomation |
AZD-5991 is under investigation in clinical trial NCT03218683 (Study of AZD5991 in Relapsed or Refractory Haematologic Malignancies.).
Mcl-1 Inhibitor AZD5991 is an inhibitor of induced myeloid leukemia cell differentiation protein (myeloid cell leukemia-1; Mcl-1; Bcl2-L-3), with potential pro-apoptotic and antineoplastic activities. Upon administration, AZD5991 binds to Mcl-1, thereby preventing the binding of Mcl-1 to and inactivation of certain pro-apoptotic proteins, and promoting apoptosis of cells overexpressing Mcl-1. Mcl-1, an anti-apoptotic protein belonging to the Bcl-2 family of proteins, is upregulated in cancer cells and promotes tumor cell survival. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
