BKT300
BKT300 is a potent and selective protein regulator of cytokinesis 1 (PRC1) inhibitor. BKT300 inhibits PRC1 dephosphorylation at T481, disrupts actin and microtubule formation, induces G2/M cell cycle arrest, triggers mitotic catastrophe, and promotes apoptosis, thereby inhibiting proliferation and migration of acute myeloid leukemia (AML) cells while sparing normal cells. BKT300 inhibits tumor growth in mouse xenograft AML models. BKT300 can be used for the research of AML.

BKT300 binds recombinant PRC1 with Kd values of 28.3 nM (SPR assay) and 104 nM (MST assay)[1].
BKT300 (31.25-5000 nM; 3 h) inhibits migration of U937 and Jurkat cells toward CXCL12, and migration of THP-1 cells toward MCP-1[1].
BKT300 (62.5-500 nM; 24 h) dose-dependently inhibits actin filament formation in U937 cells, but not in normal peripheral blood mononuclear cells (PBMCs)[1].
BKT300 (1 µM; 24 h) disrupts microtubule organization and formation in U937 cells[1].
BKT300 (7.8-5000 nM; 2-24 h) induces G2/M arrest and cell death in U937, MV4-11, OCI-AML-2, OCI-AML-3, Molm14, and Marimo AML cells[1].
BKT300 (3.9-1000 nM; 24 h) induces dose-dependent apoptosis in U937 cells, accompanied by elevated cleaved caspase-3 expression[1].
BKT300 (50-1000 nM; 24 hours) downregulates CDC25C, upregulates p21, and induces dose/time-dependent PRC1 phosphorylation at T481 in U937 and MV4-11 cells[1].
BKT300 (31.2-500 nM; 24 h) increases pPRC1 (T481) levels in U937 cells but not in normal PBMCs[1].
BKT300 (24 h) inhibits OCI-AML-3, Marimo, OCI-AML-2, MOLM-14, U937, K562, MV4-11 and HL-60 cells with IC50s of 107, 135, 120, 122, 27, 98, 98, and 110 nM, respectively[1].
