HDAC6-IN-31 (compound 8m) is a selective HDAC6 inhibitor , with the IC 50 value of 0.026 μM, that significantly inhibits the production and release of pro-inflammatory cytokines. While HDAC6 is critically involved in the activation of inflammasomes, HDAC6-IN-31 has the potential to inhibit NLRP3 inflammasome-driven inflammatory diseases. HDAC6-IN-31 also inhibits glioblastoma cell migration.
