Cat.No. 2185 - NSC 146109 hydrochloride | C17H16N2S.HCl | CAS No. 59474-01-0
Description: Cell-permeable, genotype-selective antitumor agent; activates p53-dependent transcription
Chemical Name: (10-Methyl-9-anthracenyl) methyl carbamimidothioic acid ester hydrochloride
Purity: ≥99% (HPLC)

Biological Activity

Cell-permeable, genotype-selective antitumor agent that activates p53-dependent transcription. Increases levels of endogenous p53 in tumor cells and protects p53 from Mdm2-mediated degradation. Displays some selectivity for tumor cells vs. normal cells in an MTT cell viability assay.

Cell Cycle & DNA Damage Repair Poster

In normal cells, each stage of the cell cycle is tightly regulated, however in cancer cells many genes and proteins that are involved in the regulation of the cell cycle are mutated or over expressed. Adapted from the 2015 Cancer Product Guide, Edition 3, this poster summarizes the stages of the cell cycle and DNA repair. It also highlights strategies for enhancing replicative stress in cancer cells to force mitotic catastrophe and cell death.

Pathways for NSC 146109 hydrochloride


p53 Signaling Pathway

p53 signaling plays an important role in the co-ordination of the cellular response different types of stress such as DNA damage and hypoxia. The downstream signals lead to apoptosis, senescence and cell cycle arrest.
