General description

5-Chloro-1-methyl-4-nitroimidazole is an 4-nitroimidazole derivative.

Application

5-Chloro-1-methyl-4-nitroimidazole (CMNI) is suitable for use in the rapid mix experiments to investigate the mechanism of anomalous radiosensitization of mammalian cells by CMNI. It may be used in the synthesis of 5-aryl-1-methyl-4-nitroimidazoles, via Suzuki coupling with arylboronic acids, catalyzed by dichlorobis-(triphenylphosphine)palladium(II), K2CO3 and tetrabutylammonium bromide.

The transplantable rhabdomyosarcoma in WAG/Rij rats was used to test the in vivo effectiveness of 1-methyl-2-chloro-4-nitroimidazole (P13) and its analog 1-(2-hydroxy-3-methoxy-propyl)-2-chloro-4-nitroimidazole (P40) as tumor-cell radiosensitizers after their i.p. administration at low doses. The results indicate that both compounds administered repeatedly

The "extra" radiosensitization seen with GSH-reactive nitro compounds is too large to be accounted for by GSH-depletion acting independently--there must be competition. The GS-conjugate leaks out of cells slowly and is trapped at high concentrations. Its properties, such as concentration
