چکیده
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 human cancer cells by fluorescence microscopy.

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 have demonstrated that 3-AP induces methemoglobin (metHb) formation and hy...
متن کاملα-N-Heterocyclic thiosemicarbazones induce ER stress-mediated CHOP activation
Background Blocking of DNA synthesis through inhibition of ribonucleotide reductase has been proposed to be the main mechanism of anti-neoplastic action for a-N-heterocyclic thiosemicarbazones. Currently the best-studied agent of this class of compounds is triapine (3-amino-2-carboxaldehyde thiosemicarbazone), which has been tested in several phase I and II clinical trials. We synthesized triap...
متن کاملA Ferrous-Triapine complex mediates formation of reactive oxygen species that inactivate human ribonucleotide reductase.
Ribonucleotide reductase plays a central role in cell proliferation by supplying deoxyribonucleotide precursors for DNA synthesis and repair. The holoenzyme is a protein tetramer that features two large (hRRM1) and two small (hRRM2 or p53R2) subunits. The small subunit contains a di-iron cluster/tyrosyl radical cofactor that is essential for enzyme activity. Triapine (3-aminopyridine-2-carboxal...
متن کاملTriapine and a more potent dimethyl derivative induce endoplasmic reticulum stress in cancer cells.
Triapine (3-AP; 3-aminopyridine-2-carboxaldehyde thiosemicarbazone), a ribonucleotide reductase inhibitor, has been extensively evaluated in clinical trials in the last decade. This study addresses the role of endoplasmic reticulum (ER) stress in the anticancer activity of 3-AP and the derivative N(4),N(4)-dimethyl-triapine (3-AP-Me), differing from 3-AP only by dimethylation of the terminal ni...
متن کاملIron chelators as therapeutic agents for the treatment of cancer.
A wide variety of studies in vitro, in vivo, and in clinical trials have demonstrated that the chelator currently used to treat iron overload disease, desferrioxamine, has anti-proliferative effects against both leukemia and neuroblastoma. However, the efficacy of desferrioxamine is severely limited due to its poor ability to permeate cell membranes and chelate intracellular iron pools. These s...
