Inhibition of ferrochelatase and accumulation of porphyrins in mouse hepatocyte cultures exposed to porphyrinogenic chemicals

The ability of 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC), 3,5-diethoxycarbonyl-4-ethyl-1,4-dihydro-2,6-dimethylpyridine (EDDC) and griseofulvin to induce porphyria in primary cultures of mouse hepatocytes has been examined. Exposure of cultured mouse hepatocytes to DDC, EDDC or griseofulvin resulted in a marked inhibition of ferrochelatase which was… CONTINUE READING
