چکیده

Background: NADPH:cytochrome P450 oxidoreductase (POR) catalyses one-electron reduction of hypoxia-activated prodrugs (HAP). Results: Knockout of POR in tumour cells inhibited activation of some HAP (e.g. 5nitroquinoline SN24349) but not others (e.g. PR104A, TH-302). Conclusion: POR at endogenous levels plays a variable role in HAP activation. Significance: POR expression alone is not a sufficient predictive biomarker for activation of most HAP.

FSL-61 is a 6-nitroquinolone fluorogenic probe for one-electron reductases in hypoxic cells.

One-electron reductases that reduce nitro compounds in hypoxic human tumour cells are poorly characterized, but are important for targeting hypoxia with nitroaromatic prodrugs. Fluorogenic probes with defined reductase profiles are needed to interrogate the activity of these enzymes in intact cells. In the present paper, we report a 6-nitroquinolone ester (FSL-61) as a fluorogenic probe for POR...

Radiolytic activation of a cytarabine prodrug possessing a 2-oxoalkyl group: one-electron reduction and cytotoxicity characteristics.

An anti-tumour agent of cytarabine (ara-C) was conjugated with a 2-oxopropyl group at the N(4) position to obtain a radiation-activated prodrug (oxo-ara-C) that targeted hypoxic tumour tissues with selective cytotoxicity. The parent anti-tumour agent, ara-C, was confirmed to be released from oxo-ara-Cvia one-electron reduction upon hypoxic X-ray treatment. The prodrug oxo-ara-C had dramatically...

Identification of P450 Oxidoreductase as a Major Determinant of Sensitivity to Hypoxia-Activated Prodrugs.

Hypoxia is a prevalent feature of many tumors contributing to disease progression and treatment resistance, and therefore constitutes an attractive therapeutic target. Several hypoxia-activated prodrugs (HAP) have been developed, including the phase III candidate TH-302 (evofosfamide) and the preclinical agent SN30000, which is an optimized analogue of the well-studied HAP tirapazamine. Experie...

Chemotherapy Rescues Hypoxic Tumor Cells and Induces Their Reoxygenation and Repopulation-An Effect That Is Inhibited by the Hypoxia-Activated Prodrug TH-302.

PURPOSE Chemotherapy targets rapidly proliferating tumor cells, but spares slowly proliferating hypoxic cells. We hypothesized that nutrition of hypoxic cells would improve in intervals between chemotherapy, and that hypoxic cells destined to die without treatment would survive and proliferate. EXPERIMENTAL DESIGN We therefore evaluated repopulation and reoxygenation following chemotherapy, a...

Correlation between drug uptake and selective toxicity of porfiromycin to hypoxic EMT6 cells.

Mitomycin C and its methylated analogue porfiromycin (Por) have significant potential as adjuncts to regimens presently used for treating solid tumors because of their preferential toxicity to cells existing in an hypoxic environment. An understanding of the factors producing the differential activity of these drugs under aerobic and hypoxic conditions would facilitate the development of new ag...
