A-1210477 (1668553-26-1) Description:
A-1210477 is a potent and selective MCL-1 inhibitor. A-1210477 induces the hallmarks of intrinsic apoptosis and demonstrates single agent killing of multiple myeloma and non-small cell lung cancer cell lines. A-1210477 synergizes with the BCL-2/BCL-XL inhibitor navitoclax to kill a variety of cancer cell lines. A-1210477 is a potential therapeutics for the treatment of cancer. The anti-apoptotic protein MCL-1 is a key regulator of cancer cell survival and a known resistance factor for small-molecule BCL-2 family inhibitors such as ABT-263 (navitoclax), making it an attractive therapeutic target.
A-1210477 is an effective and specific MCL-1 inhibitor with an EC50 value below 5 µmol/L Selectively, it binds to MCL-1 with an affinity of 0.45 nM.
In MCL-1-dependent SVEC cells, treatment with A-1210477 at varying doses, induced cell death in a dose-dependent manner. SYTOX Green exclusion and live-cell imaging were used to determine cell viability. In line with increased potency, cell death was more rapidly induced by A-1210477. To examine the selectivity of A-1210477 for targeting Bcl-2 family members, BcL-xL-, BcL-2-, and MCL-1-dependent SVEC cells were treated with A-1210477. A-1210477 only killed MCL-1-dependent cells. Compared with UMI-77, A-1210477 showed greater potency and specificity as an MCL-1 inhibitor, the EC50 value of UMI-77 is 10 µmol/L. In living cells, A-1210477 disrupted BIM/MCL-1 complexes. In MCL-1-dependent cancer cells, A-1210477 induced the hallmarks of mitochondrial apoptosis. In various malignant cell lines, A-1210477 induced apoptosis, synergizing with navitoclax. Data also demonstrate that A-1210477 acted through an on-target mechanism. It appeared as the first BH3 mimetic targeting MCL-1.
The pharmacokinetics of A-1210477 are not favorable for in vivo use.
