Arsenic compounds are widely used for the therapeutic intervention of multiple diseases.Ancient pharmacologists discovered the medicinal utility of these highly toxic substances,and modern phar-macologists have further recognized the specific active ingredients in human diseases.In particular,Arsenic trioxide(ATO),as a main component,has therapeutic effects on various tumors(including leukemia,hepatocellular carcinoma,lung cancer,etc.).However,its toxicity limits its efficacy,and con-trolling the toxicity has been an important issue.Interestingly,recent evidence has pointed out the pivotal roles of arsenic compounds in phase separation and membraneless organelles formation,which may determine their toxicity and therapeutic efficacy.Here,we summarize the arsenic compounds-regulating phase separation and membraneless organelles formation.We further hypothesize their potential involvement in the therapy and toxicity of arsenic compounds,highlighting potential mecha-nisms underlying the clinical application of arsenic compounds.
