Application

Tirapazamine has been used to evaluate its cytotoxic effect on U-251 MG (glioblastoma cell line) cell viability.

Biochem/physiol Actions

Under hypoxic conditions, tirapazamine is a potent cytotoxic agent that induces apoptosis by inducing breaks in single and double stranded DNA, as well as chromosomal breaks. The compound sensitizes cells to other ionizing radiation and other cytotoxic agents like cisplatin.
Under hypoxic conditions, tirapazamine is a potent cytotoxic agent..

Heterocyclic N-oxides are an interesting class of antitumor agents that selectively kill the hypoxic cells found in solid tumors. The hypoxia-selective activity of the lead compound in this class, tirapazamine, stems from its ability to undergo intracellular one-electron reduction to

Tirapazamine (TPZ, SR 4233, WIN 59075, 3-amino-1,2,4-benzotriazine 1,4-dioxide, Tirazone) is the lead compound in the benzotriazine di-N-oxide class of bioreductive anticancer agents. Extensive preclinical testing has established that the mechanism for the selective toxicity towards hypoxic cells is the result

Rationale: Nanoscale vehicles responsive to abnormal variation in tumor environment are promising for use in targeted delivery of therapeutic drugs specifically to tumor sites. Herein, we report the design and fabrication of self-accelerating H2O2-responsive plasmonic gold nanovesicles (GVs) encapsulated with
