Biological activities

NSC-207895 is a MDM2-related protein suppressor that leads to activation of p53. NSC-207895 decreases both the MDMX mRNA and protein levels in MCF-7 cells in vitro.[1] NSC-207895 induces expression of p53 as well as p53-target gene, p21 and MDM2 in MCF-7 cells in a dose-dependent manner. In another in vitro test, NSC-207895 causes a significant increase in the numbers of sub-G0/G1 cells as well as G2 arrest in MCF-7 cells. NSC-207895 also activates p53 and induces p21 and MDM2 expression in LNCaP prostate and A549 lung cancer cells. NSC-207895 induces apoptosis and inhibits cancer cell growth through inhibition of MDMX expression in MCF-7, A549 and LNCaP cells.[1] NSC-207895 dose-dependently elevates the mRNA levels of proapoptotic genes including PUMA, BAX, and PIG3 in MCF-7 cells. In MCF-7 cells, NSC-207895 cooperates with the MDM2 inhibitor nutlin-3a to activate p53 and decrease cell survival. NSC-207895 results in more than 40% of cells dying via apoptosis with the concentration of 5µM for 5 days in MCF-7 cells. NSC-207895 also induces inhibition of nucleoside uptake and phosphorylation, DNA, RNA, and protein synthesis, as well as degradation of DNA in L1210 cells.[2]

Protocols

NSC-207895 is dissolved in N, N??dimethyformaide in vitro.[2]
