IC50: 150, 500 and 400 nM for Aurora Kinase A, B and C respectively

Reversine is a novel Aurora kinases inhibitor. Aurora kinases are serine/threonine kinases playing a key role in mitotic regulation. Aurora A kinase resides at spindle poles during mitosis and is implicated in the control of centrosome maturation, duplication, and separation. Aurora B is part of a chromosome passenger complex and is implicated directly in the control of microtubule kinetochore attachment. Aurora kinases have emerged as valuable targets in cancer therapy.

In vitro: Reversine could be used to induce dedifferentiation of murine myoblasts. Previous reports also showed that reversine had a role in regeneration. Moreover, a recent report indicated reversine had anti-tumor capabilities for a myeloma cell line, as demonstrated by that reversine could suppress the expression of cell cycle related proteins Aurora kinase A and Aurora kinase B [1].

In vivo: The effects of reversine on tumor weight and volume were assessed using a murine model of cervical cancer with U14 cells, separately or combined with aspirin. The inhibition rate of cells in the combination group significantly increased; moreover, such combination could synergistically inhibit the proliferation of five cervical cancer cell lines. In the mouse model, tumor weight and volume of cervical cancer bearing mice were more reduced [1].

Clinical trial: N/A
