Amifostine trihydrate
Based on 16 publication(s) in Google Scholar
Amifostine trihydrate (WR2721 trihydrate) is a broad-spectrum cytoprotective agent and a radioprotector. Amifostine trihydrate selectively protects normal tissues from damage caused by radiation and chemotherapy. Amifostine trihydrate is potent hypoxia-inducible factor-α1 (HIF-α1) and p53 inducer. Amifostine trihydrate protects cells from damage by scavenging oxygen-derived free radicals. Amifostine trihydrate reduces renal toxicity and has antiangiogenic action.
