Cyclic Pifithrin-α hydrobromide
Cat. No. 3843
Alternative Name: Pifithrin-β
Chemical Name: 5,6,7,8-Tetrahydro-2-(4-methylpheny
Biological ActivityCyclic analog of pifithrin-α (Cat. No. 1267), a small molecule inhibitor of p53. Prevents dexamethasone-induced cell death in murine thymocytes (EC50 = 2.01 μM). Sensitizes p53-deficient tumors to radiotherapy and chemotherapy; increases apoptosis in target cells when used in combination with antimicrotubule agents.
