| In Vitro | BET bromodomain inhibitor 1 (compound 38; 31.25-125 nM; 24 hours) leads to more pronounced G1-phase cell cycle arrest[1]. BET bromodomain inhibitor 1 (31.25-500 nM; 6 or 24 hours) is highly effective in inducing dose-dependent inhibition on c-Myc expression and upregulation of p21 levels[1]. BET bromodomain inhibitor 1 (31.25-125 nM; 6 hours) robustly reduces the expressions of c-Myc, BCL-2, and CDK6[1]. BET bromodomain inhibitor 1 does not inhibit five cytochrome P450 enzymes (IC50>20 μM)[1]. BET bromodomain inhibitor 1 demonstrates an excellent selectivity for the BET bromodomain family over other bromodomains, with an ∼1500-fold selectivity for BRD4(1) over EP300 (IC50=3857 nM)[1]. BET bromodomain inhibitor 1 strongly inhibited the growth of acute myeloid leukemia cell line MV4-11, acute leukemia cell lines Kasumi-1 and RS-4-11, and multiple myeloma cancer cell line MM1.S cells with IC50 values of 2.4, 4.8, 17.6 and 15.1 nM, respectively[1]. Cell Cycle Analysis[1] Cell Line: MV-4-11 cells Concentration: 31.25, 62.5, 125 nM Incubation Time: 24 hours Result: Led to more pronounced G1-phase cell cycle arrest. Western Blot Analysis[1] Cell Line: MV-4-11 cells Concentration: 31.25, 62.5, 125, 250, 500 nM Incubation Time: 6 or 24 hours Result: Induced dose-dependent inhibition on c-Myc expression and upregulation of p21 levels. RT-PCR[1] Cell Line: MV-4-11 cells Concentration: 31.25, 62.5, 125 nM Incubation Time: 6 hours Result: Robustly reduced the expressions of c-Myc, BCL-2, and CDK6. |
| In Vivo | BET bromodomain inhibitor 1 (compound 38; 6.25, 12.5 mg/kg; PO; daily ; for 28 days) exhibits stronger antitumor activities and completely inhibits the growth of tumor with a tumor growth inhibition (TGI) of 99.7% at 12.5 mg/kg[1]. BET bromodomain inhibitor 1 (1 mg/kg; IV) has a T1/2 of 1.3 hours, a CL of 21.5 mL/min•kg, and a Vss of 1464 mL/kg for rats[1]. BET bromodomain inhibitor 1 (3 mg/kg; PO) has a T1/2 of 3.6 hours, a Cmax of 159 ng/mL and an AUC of 884 ng•h/mL for rats[1]. BET bromodomain inhibitor 1 (1 mg/kg; IV) has a T1/2 of 0.9 hours, a CL of 15.3 mL/min•kg, and a Vss of 782 mL/kg for mouse[1]. BET bromodomain inhibitor 1 (1.3 mg/kg; PO) has a T1/2 of 1.3 hours, a Cmax of 399 ng/mL and an AUC of 1710 ng•h/mL for mouse[1]. Animal Model: An MV4-11 mouse xenograft model[1] Dosage: 6.25, 12.5 mg/kg Administration: PO; daily ; for 28 days Result: Exhibited stronger antitumor activities and completely inhibited the growth of tumor with a tumor growth inhibition (TGI) of 99.7% at 12.5 mg/kg. Animal Model: Male SD rats[1] Dosage: 1 mg/kg (Pharmacokinetic Analysis) Administration: IV Result: Had a T1/2 of 1.3 hours, a CL of 21.5 mL/min•kg, and a Vss of 1464 mL/kg. |
