| 半岛bd体育手机客户端 描述 | IC50: N/A Pifithrin-α is an inhibitor of p53 blocking p53-dependent transactivation of p53-responsive genes. Chemotherapy and radiation therapy for cancer often have severe side effects that limit their efficacy. P53 determines the toxic side effects of anticancer treatment, and thus may be an appropriate target for reducing the damage to normal tissues in the process of anticancer therapy [1]. Therefore, to find inhibitors of p53 may be effective method for reducing the side effects of cancer therapy and other types of stress associated with p53 induction. In vitro: Pifithrin-α blocks p53-dependent transactivation of p53-responsive genes in ConA cells. Pifithrin-α (10 μM) inhibits apoptotic death of C8 cells guided by etoposide, Taxol, Dox, cytosine arabinoside. Pifithrin-α has significant effect on the inhibition of p53-dependent growth arrest of human diploid fibroblasts in response to DNA damage but not on p53-deficient fibroblasts. Pifithrin-α may monitor the nuclear import or export (or both) of p53 or may make nuclear p53 instability [2]. In vivo: Pifithrin-α-mice (2.2 mg/kg i.p.) were completely survival with both strains from 60% killing doses of gamma irradiation (8 Gy for C57BL and 6 Gy for Balb/c). Mice pretreated with Pfithrin-α lost less weight than irradiated mice without the Pifithrin-α. Pifithrin-α (2.2 mg/kg) eliminates p53-dependent regulation of DNA replication after whole-body gamma irradiation in mice [2]. Clinical trial: So far, no clinical study has been conducted.
