Description

Amifostine is the trihydrate form of a phosphorylated aminosulfhydryl compound. After dephosphorylation of amifostine by alkaline phosphatase to an active free sulfhydryl (thiol) metabolite, the thiol metabolite binds to and detoxifies cytotoxic platinum-containing metabolites of cisplatin and scavenges free radicals induced by cisplatin and ionizing radiation. The elevated activity of this agent in normal tissues results from both the relative abundance of alkaline phosphatase in normal tissues and the greater vascularity of normal tissues compared to tumor tissues.|A phosphorothioate proposed as a radiation-protective agent. It causes splenic vasodilation and may block autonomic ganglia.

Drug Function and Efficacy

This product is an organic thiophosphate compound. After being hydrolyzed and dephosphorylated by alkaline phosphatase bound to the cell membrane in the tissue, it becomes an active metabolite WR-1065, whose chemical structure is H2N-(CH2)3-NH-(CH2)2-SH. Because the sulfhydryl group has the function of scavenging free radicals in the tissue, it can reduce the toxicity of cisplatin, cyclophosphamide and mitomycin.

This ingredient has been used in drugs with the following functions (note: it does not mean that the ingredient itself has the following health functions)
