چکیده

3-Hydroxypy rid ine-2-carboxaldehyf le thiosemicarbazone (3-HP) has been shown to be active against leukemia L1210, Ehrlich ascites carcinoma, lym]>homa L5178Y, the Lewis lung carcinoma, and adenocarcinoma 755. 3-HP is active, in some in stances, by gavage and also by delayed treatment. 3-HP is a member of a broad class of a-(.Y)-heterocyclic carboxaldehyde thiosemicarbazones, several of which have demonstrable carcinostatic activity. The active compounds share several elec tronic, structural, and reactive features in common. They all contain the N*—N*-—S* tridentate ligand system.

α-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...

Carcinostatic action of polycarbonyl compounds and their derivatives. II. Glyoxal bis (guanylhydrazone) and derivatives.

The authors have previously investigated the carcinostatic effect of simple hydrazine deriva tives. In early work (6, 7) acetic hydrazide and some methylated derivatives of formic hydrazide were found to have an inhibitory effect on mouse Adenocarcinoma 755. A number of substituted hydrazines and related compounds were also evaluated on myeloid mouse leukemia C1498 (8). The development of hydra...

Antimicrobial activity of two antitumour agents and ribonucleotide reductase inhibitors, pyridine-2-carboxaldehyde thiosemicarbazone and the acetate form of its copper(II) chelate.

Some copper chelates have potent antitumour activity, and in some cases also the free ligands have activity in vivo. Yet, little is known about their antimicrobial properties. Copper(II) chelates of the thiosemicarbazones of a-N-heterocyclic carboxaldehydes constitute one important group of such agents, also their ligands having marked antitumour activity. Both the ligands and chelates inhibit ...

Studies of the antineoplastic activity and metabolism of -(N)-heterocyclic carboxaldehyde thiosemicarbazones in dogs and mice.

SUMMARY The antineoplastic effects of a-(/V)-heterocyclic Carboxaldehyde thiosemicarbazones were studied in dogs with lymphosarcoma, and some of their metabolic features were studied in both mice and dogs. Significant regression (38 to 72%) of tumor masses occurred in dogs treated with i.v. doses of 2 to 6 mg of the sodium salt of 1-formylisoquinoline thiosemicarbazone per kg for a maximum of 5...
