A nitroimidazole-based hypoxic cell-radiation sensitizer and anti-infective against Trichomonas vaginalis.
Nimorazole is a nitroimidazole-based hypoxic cell-radiation sensitizer with less toxicity than etanidazole or misonidazole. Under low oxygen (hypoxic) condition, reductive activation of its 5-nitroimidazole moiety leads to enhanced adduct formation with reduced glutathione, which form the basis of cancer/tumour-selective radiation sensitization. Nimorazole is also a known anti-infective agent against trichomoniasis, an infectious disease caused by the protozoan parasite Trichomonas vaginalis.
Hypoxia is a characteristic feature of solid tumours that significantly reduces the efficacy of conventional radiation therapy. In this study we investigated the role of hypoxia in a stereotactic radiation schedule by using a variety of hypoxic modifiers in a
Tumour hypoxia renders cancer cells resistant to cancer therapy, resulting in markedly worse clinical outcomes. To find clinical candidate compounds that reduce hypoxia in tumours, we conduct a high-throughput screen for oxygen consumption rate (OCR) reduction and identify a number
