Description: ARN5187 is a novel dual inhibitor of REV-ERBβ and autophagy with potential anticancer activity. ARN5187 showed improved cytotoxicity against BT-474 breast cancer cells compared to chloroquine, a clinically relevant autophagy inhibitor. Dual inhibition of REV-ERBβ and autophagy is an effective strategy for eliciting cytotoxicity in cancer cells. REV-ERBα and REV-ERBβ nuclear receptors regulate several physiological processes, including circadian rhythm and metabolism. the REV-ERBα gene is co-overexpressed with ERBB2 in breast cancer cell lines.
