Fluorine-containing pharmaceuticals approved by the FDA in 2020:Synthesis and biological activity

Thirteen new fluorine-containing drugs,which have been granted approval by the US Food and Drug Administration(FDA)in 2020,are profiled in this review.Therapeutic areas of these new fluorinated pharmaceuticals include medicines and diagnostic agents for Cushing's disease,neurofibromatosis,migraine,Alzheimer's disease,myelodysplastic syndromes,hereditary angioedema attacks,and various cancers.Molecules of these approved drugs feature aromatic fluorine(Ar-F)(11 compounds),aromatic Ar-CF_(3)(1),aliphatic CHF(1)and CF_(2)(1)groups.For each compound,we provide a spectrum of biological activity,medicinal chemistry discovery,and synthetic approaches.
