Description

General description

A cell permeable pyridoindole based compound that acts as a highly potent and selective inhibitor of breast tumor kinase (Brk; IC₅₀ = 3.15 nM) with minimal or no effect against a panel of more than 30 other protein kinases (IC₅₀ = <10 µM for PIM2, NEK1 and2, CAMK4, MAPKAPK3 and 5 and MARK1, 3, and 5). Does not affect the activity of Akt isoforms, AGC kinases, ERK1 and 2, JNK 1 and 2 and HIPK isoforms. Displays anti-proliferative activity against multiple breast cancer cell lines (GI₅₀ = 990 nM; 1.02 µM, and 1.58 µM for MCF7, HS-578/T, BT-549, respectively).
