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.
The study assessed the effectiveness of thienyl phencyclidine (TCP) and its new derivatives against organophosphate and carbamate poisoning in mice.
Both TCP and its derivatives showed low toxicity levels and provided protective effects when used with atropine, particularly against carbamate poisons like propoxur and aldicarb.
However, their efficacy was reduced for organophosphate poisons; the best results were achieved using a combination of HI-6 (an antidote) with atropine and the test compounds against soman poisoning.
