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.

Product Data:
Biological target: A-1210477 is a MCL-1 inhibitor with an IC50 of 26.2 nM.
In vitro activity: Esophageal cell proliferation was reduced markedly following A-1210477 treatment. The apoptotic cells of these ESCC (esophageal squamous cell carcinoma) were evaluated after A-1210477 treatment by detecting cleaved caspase3 expression with quantitative IHC (immunohistochemistry). There was a statistically significant increase in labeling indices when control ESCC (1.2 ± 0.8) was compared with low dose (8.0 ± 3.1) and high dose ones (14.0 ± 4.5) (Figure 4A–4D). The percentage of TUNEL positive cells increased dose dependently from 1.9 % in DMSO mice to 8.9 % (p < 0.05) in low-dose A-1210477 mice and 19.0 % (p < 0.05) in high-dose A-1210477 mice (Figure 4E–4N). These data clearly demonstrated A-1210477 treatment led to increased cell death in mouse ESCC.

In vivo activity: To test whether MCL-1 plays a role in ESCC cancer progression, mice at 20 weeks after initial 4NQO exposure were injected with control vehicle, lose dose and high dose of A-1210477 daily for 4 weeks. A-1210477-treated mice had developed fewer tumors than the vehicle-treated mice did in a dose dependent manner (Figure 2A). Similarly, there was significant less body weight loss in the A-1210477-treatment group mice compared with the control ones (Figure 2B). Microscopically, there was also less malignancy formation in the esophagus following A-1210477-treatment (Figure 2C–2E).
