Biochem/physiol Actions

3-Aminopyridine-2-carboxaldehyde thiosemicarbazone (3-AP) is a ribonucleotide reductase inhibitor and iron chelator with anti-tumor activity.
3-aminopyridine carboxaldehyde thiosemicarbazone (3-AP) has a IC50 value of 0.3μM. It exhibits anti-proliferative activity in preclinical models of cancer, such as lung cancer. It also has an ability to increase the cytotoxicity, intracellular uptake and DNA incorporation of gemcitabine in vitro.

Triapine (3-aminopyridine-2-carboxaldehyde thiosemicarbazone, 3-AP) is currently the most promising chemotherapeutic compound among the class of α-N-heterocyclic thiosemicarbazones. Here we report further insights into the mechanism(s) of anticancer drug activity and inhibition of mouse ribonucleotide reductase (RNR) by Triapine. In addition

The thiosemicarbazones Dp44mT (di-2-pyridylketone-4,4-dimethyl-3-thiosemicarbazone) and triapine have potent antiproliferative activity and have been evaluated as anticancer agents. While these compounds strongly bind iron and copper, their mechanism(s) of action are incompletely understood. A recent report (Rao et al., Cancer Research

Thiosemicarbazones are a group of compounds that have received comprehensive investigation as anticancer agents. The antitumor activity of the thiosemicarbazone, 3-amino-2-pyridinecarboxaldehyde thiosemicarbazone (3-AP; triapine), has been extensively assessed in more than 20 phase I and II clinical trials. These studies
