Abstract

- Earlier we have described new water-soluble Ag-and Zn-derivatives of tetrachloridemeso-tetra(4-N-oxiethylpyridyl) porphyrin(TOEtPyP) as potential anticancer drugs. In this workthe effect of one of these metal porphyrins, TOEtPyP Ag, on the cell population kinetics was stu-died in vitrousing morphological and biochemical techniques. The results suggested thatTOEtPyP Ag action consisted in the simultaneous suppression of the cell growth and activation ofthe cell death. About 40% of the cells were shown to die via apoptotic pathway. So, the porphyrinstudied may be attributed to inducers of both necrotic and apoptotic processes. The results ob-tained support our previous assertion that TOEtPyP Ag may be considered as a potential che-motherapeutic agent.
