Biochem/physiol Actions

Studies have also reported that UA62784 associates with tubulin at or near the colchicine-binding sites in cells and functions as a cytotoxic, microtubule inhibitor.
UA62784 is a specific inhibitor of centromere protein E (CENPE) kinesin-like protein; mitotic inhibitor. CENP-E is a kinesin-like motor protein that localizes to the kinetochore during mitosis and is essential for bipolar spindle formation. UA62784 is a novel specific inhibitor of CENP-E, which likely binds within the motor domain of CENP-E. UA62784 causes reversible cell cycle arrest in mitosis before metaphase, which leads to apoptosis. The compound is not interacting with microtubules directly.

Preparation Note

UA62784 is soluble in DMSO at a concentration >2 mg/ml.

A recent screen for compounds that selectively targeted pancreatic cancer cells isolated UA62784. We found that UA62784 inhibits microtubule polymerization in vitro. UA62784 interacts with tubulin dimers ten times more potently than colchicine, vinblastine, or nocodazole. Competition experiments revealed that UA62784

Functional genomic screening of KRAS-driven mouse sarcomas was previously employed to identify proliferation-relevant genes. Genes identified included Ubiquitin-conjugating enzyme E2 (Ube2c), Centromere Protein E (Cenpe), Hyaluronan Synthase 2 (Has2), and CAMP Responsive Element Binding Protein 3 Like 2 (Creb3l2). This
