Radioprotective effect of a new synthetised adamantyl-thienylcydine

Several adamantyl derivatives of tenocyclidine,1-[1(2-thienylcyclohexyl)]piperidine (TCP), were synthetised and characterised (Ad-TCP I-IV).Their biological activity was evaluated by in vitro testing of their effect on proliferative and reproductive ability of human tumor strain and non- malignant mouse fibroblasts in culture.These effects were compared with those of tenocyclidine (TCP).We also tested them on cultured cells,for their radioprotective effect after ionising irradiation. The results with non-malignant mouse fibroblasts and human tumour cells show that the piperidine derivative of adamantyl tenocyclidine (Ad-TCP II)has rather outstanding radioprotective properties.This derivative revealed significant radioprotection at all survival levels,depending on the malignant or non-malignant origin of the cells,and it was significantly more evident on mouse fibroblasts then on human tumor cells.These effects were compared with those of tenocyclidine.
