Reversine is a potent small-molecule inhibitor of Aurora kinases (Aurora A/B) and Plk1, with a core mechanism involving inhibition of mitotic kinases to induce mitotic arrest and subsequent apoptosis in cancer cells. It also exhibits the unique property of inducing dedifferentiation of mesenchymal stem cells [2,3,4]
- In solid tumors (colon cancer, pancreatic cancer) and hematological malignancies (leukemia), Reversine exerts anti-tumor effects by disrupting mitotic spindle formation (via Aurora kinase inhibition) and activating cell cycle checkpoints (via p21WAF1/CIP1 upregulation) [2,3] - The dedifferentiation effect of Reversine on hMSCs suggests potential applications in regenerative medicine, though its primary preclinical focus remains on anti-tumor therapy [4] - Preclinically, Reversine shows moderate oral bioavailability and favorable tumor penetration, supporting its potential as an oral or injectable anti-tumor agent for solid and hematological cancers [3,4] |
