BRD4-IN-12 is a potent and orally active BRD4 inhibitor with an IC50 of 7.9 nM. BRD4-IN-12 downregulates the expression of c-MYC, BCL-2, CDK4 and upregulates p21. BRD4-IN-12 inhibits tumor cell proliferation and promotes apoptosis. BRD4-IN-12 exhibits excellent antitumor effects in the HCT-116 colorectal cancer xenograft model. BRD4-IN-12 can be used for the study of colorectal cancer (CRC).

Description

BRD4-IN-12 is a potent and orally active BRD4 inhibitor with an IC50 of 7.9 nM. BRD4-IN-12 downregulates the expression of c-MYC, BCL-2, CDK4 and upregulates p21. BRD4-IN-12 inhibits tumor cell proliferation and promotes apoptosis. BRD4-IN-12 exhibits excellent antitumor effects in the HCT-116 colorectal cancer xenograft model. BRD4-IN-12 can be used for the study of colorectal cancer (CRC)[1].

In Vitro

BRD4-IN-12 (H5) (72 h) shows cytotoxicity against HCT-116 colorectal cancer cells with an IC50 value of 0.84 μM, the cytotoxicity of BRD4-IN-12 induced in HCT-116 cells is BRD4-dependent[1].
BRD4-IN-12 (1.25-5.0 μM; 24 h) downregulates the protein expression of c-MYC, CDK4 and BCL-2, and dose-dependently upregulates the protein expression of p21 in HCT-116 cells[1].
BRD4-IN-12 (20 μM; 3 h) stabilizes BRD4 protein in HCT-116 cell lysates, confirming its intracellular binding to BRD4[1].

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

In Vivo

BRD4-IN-12 (H5) (25 mg/kg or 50 mg/kg; p.o.; once a day; for 18 days) exhibits 52% and 82% tumor growth inhibition (TGI) at 25 mg/kg and 50 mg/kg, respectively, in male BALB/c nude mice bearing HCT-116 colorectal cancer xenografts; maintains stable body weight and causes no significant pathological damage to major organs (heart, liver, spleen, lung, kidney); and downregulates the expression of c-MYC and BCL-2 in tumor tissues; induces increased cell spacing, smaller and rounded nuclei in tumor tissues of male BALB/c nude mice with HCT-116 colorectal cancer xenografts[1].

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

Animal Model: Male BALB/c nude mice (4-6 weeks old, 18-22 g) were subcutaneously inoculated with HCT-116 cells (5 × 106 cells/mL)[1].
Dosage: 25 mg/kg or 50 mg/kg
Administration: Dissolved in vehicle containing 5% ethanol, 40% PEG 400, 5% Tween 80, and 50% water; Oral (p.o.) administration; once daily; for 18 days
Result: Both doses maintained stable body weight and caused no obvious pathological damage to major organs (heart, liver, spleen, lung, kidney).
Both doses downregulated the expression of c-MYC and BCL-2 in tumor tissues and induced increased cell spacing, smaller and rounded nuclei in tumor tissues (H&E staining).
The 25 mg/kg dose exhibited 52% tumor growth inhibition (TGI) without significant body weight loss.
The 50 mg/kg dose achieved 82% tumor growth inhibition (TGI) and downregulated the expression of c-MYC and BCL-2 in tumor tissues.

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.
