DW34 is an orally active pan-BRD4-D1 biased inhibitor with additional BRD4-D2 inhibitive activity. DW34 displays comparable inhibitive efficacy to I-BET151 (HY-13235) (EC50 = 0.16 μM) with low nanomolar EC50 values of 0.14 μM. DW34 significantly reduces liver inflammation induced by LPS (HY-D1056) and APAP (HY-66005) via reducing chemokine expression and cellular necrosis.

Description

DW34 is an orally active pan-BRD4-D1 biased inhibitor with additional BRD4-D2 inhibitive activity. DW34 displays comparable inhibitive efficacy to I-BET151 (HY-13235) (EC50 = 0.16 μM) with low nanomolar EC50 values of 0.14 μM. DW34 significantly reduces liver inflammation induced by LPS (HY-D1056) and APAP (HY-66005) via reducing chemokine expression and cellular necrosis[1].

In Vitro

DW34 (Compound 3) (0.31-5 μM, 5 h) inhibits both CXCL1 and CCL2 expression induced by LPS (HY-D1056) (200 ng/mL, 4 h) in transformed sinusoidal endothelial cells (TSECs)[1].

DW34 (0.5-5 μM, 2 h) stabilizes BRD4 at comparable concentrations to I-BET151 (HY-13235) in HEK293T cells[1].

DW34 (0.1-200 μM, 4 h) shows good tolerance in transformed sinusoidal endothelial cells (TSECs)[1].

DW34 induces a toxicity profile with an EC50 of 90 nM in megakaryocytes[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
