PK11007 cas 38275-34-2

PK11000 is a mild thiol alkylator with anticancer activity in several cell lines, especially those with mutationally compromised p53. It effectively kills cancer cells, especially with null or mutant p53 background, and shows only low cytotoxicity toward normal cells. PK11000 acts by two routes: p53 dependent and p53 independent. PK11000 stabilized p53 in vitro via selective alkylation of two surface-exposed cysteines without compromising its DNA binding activity. Unstable p53 was reactivated by PK11000 in some cancer cell lines, leading to up-regulation of p53 target genes such as p21 and PUMA. PK11007 induces mainly caspase-independent cell death.
