Several new adamantyl derivatives of thienyl phencyclidine (TCP) were synthesized and tested for biological activity, focusing on their effects on human tumor cells and nonmalignant mouse fibroblasts.
These derivatives, particularly TAMORPH, showed reduced toxicity and improved radioprotective properties compared to TCP, promoting greater apoptotic death in cancer cells.
In vivo studies on C3Hf mice indicated that these derivatives provided enhanced radioprotection while being less toxic than the original TCP compound.
