Cat. No. 2443
Alternative Name: NSC 652287
Chemical Name: 5,5'-(2,5-Furandiyl)bis-2-thiophenem
Biological ActivityAnti-tumor agent that binds wild-type p53 (Kd = 1.5 nM) preventing p53-MDM2 (HDM2) interaction. Induces p53 accumulation and stimulates apoptosis in tumor cell lines expressing wild-type p53 in vitro and in vivo. Inhibits HPV-E6-mediated proteasomal degradation. Suppresses expression of cervical carcinoma HeLa xenografts in vivo.
