Clioquinol
Based on 6 publication(s) in Google Scholar
Clioquinol (Iodochlorhydroxyquin) is a topical antifungal agent with anticancer activity. Clioquinol acts as an oral antimicrobial agent for the research of diarrhea and skin infections. Antibiotic. Clioquinol is a chelator that binds to Zn2+ and Cu2+ with a greater affinity than it binds to Ca2+ and Mg2+. Clioquinol freely crosses the blood-brain barrier. Clioquinol can be used for the study of Alzheimer's disease.
