IBPR002
IBPR002 is an inhibitor of Aurora kinase A and Aurora kinase B, with IC50 values of 41 nM and 17 nM, respectively. IBPR002 disrupts the nucleation and bundling of kinetochore microtubules, impairs the bipolarity of mitotic spindles, and promotes the binding of non-phosphorylated hepatoma up-regulated protein (HURP) to microtubules derived from the mother centrosome. IBPR002 reduces tumorigenesis levels in a colorectal cancer xenograft model using athymic nude mice. IBPR002 is applicable for research related to colorectal cancer.

IBPR002 (1.0 μM; 13 h) disrupts bipolar spindle formation and restricts unphosphorylated HURP to the minus ends of centrosomal microtubules, inducing three distinct mitotic phenotypes in HeLa cells[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Cell Line:HeLa cells
-
Concentration:1.0 μM
-
Incubation Time:13 h (after thymidine release)
-
Result:Induced three distinct HURP localization phenotypes: ~20% of cells showed a monoastral spindle with HURP surrounding unseparated centrosomes (Phenotype-1), the majority showed HURP associated with centrosomal microtubules projecting toward chromosomes from one separated centrosome (Phenotype-2) or both separated centrosomes (Phenotype-3).
Disrupted bipolar spindle formation.
Restricted HURP to the minus ends of centrosomal microtubules, unlike control cells where HURP localizes to both ends of microtubules.

Animal Model:athymic nude (male)[1]
-
Dosage:50 mg/kg
-
Administration:i.v.; five daily doses per week; two consecutive weeks
-
Result:Significantly inhibited growth of xenograft colorectal cancer cells, with mean tumor volume at study end being substantially lower than vehicle control levels.
