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.

Jia Shou et al.
Molecular cell, 71(4), 498-509 (2018-07-24)
Chromosomal rearrangements including large DNA-fragment inversions, deletions, and duplications by Cas9 with paired sgRNAs are important to investigate genome structural variations and developmental gene regulation, but little is known about the underlying mechanisms. Here, we report that disrupting CtIP or

Therapeutic ionizing radiation damages DNA, increasing p53-regulated ribonucleotide reductase (RNR) activity required for de novo synthesis of the deoxyribonucleotide triphosphates used during DNA repair. This study investigated the pharmacological inhibition of RNR in cells of virally or mutationally silenced p53

Triapine (3-aminopyridine-2-carboxaldehyde thiosemicarbazone), which entered several phase I and II clinical trials as an antitumor chemotherapeutic agent, was found to possess intrinsic fluorescence properties (lambda(ex) = 360 nm), which enabled us to monitor the uptake and intracellular distribution in living

The enzyme RR catalyzes the conversion of ribonucleoside diphosphates to their deoxyribonucleotide counterparts. RR is critical for the generation of the cytosine, adenine, and guanine deoxyribonucleotide 5'-triphosphate building blocks of DNA, which are present in cells as exceedingly small intracellular

Stoichiometry and stability of Ga(III), Fe(III), Fe(II) complexes of Triapine and five related α-N heterocyclic thiosemicarbazones with potential antitumor activity have been determined by pH-potentiometry, UV-vis spectrophotometry, (1)H NMR spectroscopy, and spectrofluorimetry in aqueous solution (with 30% DMSO), together with
