In initial studies with yeast cells it was found that the primary target of the antidepressant chlorimipramine (Anafranil, CIBA-Geigy) and the anti-leprosy drug clofazimine (Lamprene, CIBA-Geigy) was the mitochondrion (Hughes & Wilkie 1970, Rhodes & Wilkie 1973). Both drugs inhibited the respiratory chain, although by different mechanisms. The oxygen uptake of isolated rat liver mitochondria was affected in a similar way to that of the intact yeast mitochondria. When these studies were extended to human skin fibroblast cultures (Wilkie & Delhanty 1970, Delhanty et al. 1974, Mittwoch & Wilkie 1971), both drugs again had a direct effect on oxygen uptake in the human cells similar to that in yeast cells. The significant finding in this series of experiments was that SV-40 transformed cells (cancer type) were much more susceptible to the inhibitory effects of the drugs than the non-transformed fibroblasts. Results with chlorimipramine on transformed cells are included in the above references, while clofazimine results showed that about 2 jsg/ml in the culture medium was a lethal dose for transformed fibroblasts but about 8 jig/ml was required to kill non-transformed cultures (unpublished results). It was noted that the respiratory rate of transformed cells was significantly less than their normal counterparts in oxygen electrode studies (Wilkie & Delhanty 1970). These results indicated that depression of mitochondrial activity (already low), in the cancer type cells, by treatment with antimitochondrial agents kills these cells, while normal cells can recover from this treatment.
