Beschreibung
RITA (reactivation of p53 and induction of tumor cell apoptosis, 213261-59-7) binds to p53 (Kd = 1.5 nM), changing its conformation, preventing it from binding to HDM2 and preventing its proteasomal degradation.1 It also weakly (computed Kd = 22 μM) binds HDM2 in the cleft that contacts the p53 transactivation domain.2 Its restoration of mutant p53 function depends on eIF2α phosphorylation, and it induces apoptosis via p53-dependent and -independent (JNK/SAPK/p38; protein translation) pathways.3-5 Induces senescence in head and neck cancer cells.6
Verwenden
NSC 652287, a DNA damaging agent. It induces p53 tumor suppressor protein.
Verwenden
A cell-permeable, p53-targeting, tricyclic thiophene derivative
Definition
ChEBI: [5-[5-[5-(hydroxymethyl)-2-thiophenyl]-2-furanyl]-2-thiophenyl]methanol is a member of thiophenes.
Biologische Aktivität
Anti-tumor agent that binds wild-type p53 (K d = 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 .
in vitro
a number of cell lines showed a striking differential sensitivity to nsc 652287 when compared with the other cell lines in the panel, with gi50 values of 10–60 nm. the compound was found to decrease the initial number of cells by 50% (lc50) at a concentration of 100 nm in the a-498 cell line, compared with ~100 mm for the majority of the tumor cell lines. the a-498 and tk-10 cell lines were particularly sensitive to nsc 652287-induced cytotoxicity compared with achn and uo-31 cell lines [1].
in vivo
nsc 652287 was evaluated against a-498 tumor cell xenografts grown subcutaneously in nude mice. when nsc 652287 was administered twice a day, all three doses resulted in complete tumor regression in 100% of the treated mice by the end of the third treatment period. the tumors did not regrow during the remaining 40 days of the study, and no gross evidence of toxicity was observed. studies with xenografts derived from other sensitive cell lines including the renal caki-1, melanoma uacc-257, ovarian ovcar-5, and colon hcc-2998, showed moderate or minimal in vivo activity [2].
IC 50
2 nm and 20 nm for a-498 and tk-10, respectively
Lager
Store at -20°C
