產品描述：

PRIMA-1MET selectively restores the activity of mutant p53 in tumor cells.[1]

The p53 is encoded in humans by the TP53 gene. The molecular mass of p53 is 53 KD. The p53 has the function of regulating the cell cycle, thus, it functions as preventing cancer, a tumor suppressor. The p53 plays an important role in apoptosis, inhibition of angiogenesis and genomic stability by activating DNA repair proteins, arresting cell growth though holding the cell cycle and initiating apoptosis. p53 becomes activated in response to DNA damage, osmotic shock, oxidative stress or other myriad stressors. Activated p53 activates the expression of several genes by binding DNA including p21. p21 binds to the G1-S/CDK complexes which is an important molecules for the G1/S transition, then causes cell cycle arrest. The increasing amount of p53 may be a solution for prevention of tumors spreading or treatment of them. About half of human tumours have mutant p53 then lose the control for cell apotosis.[2]

PRIMA-1MET is a methylated derivative of PRIMA-1. PRIMA-1 suppressed the growth of Saos-2-His-273 osteosarcoma cell but did not affect the cell lines which express wild type P53. PRIMA-1 directly binds to mutant p53 according to gel shift assay.[2] PRIMA-1MET induced nucleolar translocation of Hsp70, PML, CBP and p53 in MCF 7 cells.[3] PRIMA -1MET reactivate the mutant p53, then results in enhanced expression of genes which are involved in apoptosis and cell-cycle regulation[4]. In the H1299-His175 cells, treatment with 50μM PRIMA-1MET leaded to significant caspase-2 activation , then induced mitochondria-mediated apoptosis.[1]

PRIMA-1 MET at 25μM reduced the IC50 of cisplatin in H1299 cells by inducing mutant P53-dependent apotosis.[5]

In SCID mice with H1299-His175 tumor xenografts, the combination of PRIMA-1MET at 100mg/Kg and cisplatin significantly inhibited tumor grown compared to cisplatin only. [5]
