Crisaborole, sold under the brand name Eucrisa, is a nonsteroidal topical medication used for the treatment of mild-to-moderate atopic dermatitis (eczema) in people two years or older. It was approved by U.S. Food and Drug Administration on Dec 14, 2016 and June 6, 2018 by Health Canada.
Crisaborole is a phosphodiesterase-4 inhibitor, mainly acting on phosphodiesterase 4B (PDE4B), which causes inflammation. Chemically, crisaborole is a phenoxybenzoxaborole. Inhibition of PDE4B appears to suppress the release of tumor necrosis factor alpha (TNFα), interleukin-12 (IL-12), IL-23 and other cytokines, proteins believed to be involved in the immune response and inflammation.
Crisaborole (chemical name: 4-[(1-hydroxy-1,3-dihydro-2,1-benzoxaborol-5-yl)oxy]benzonitrile) is a member of the class of benzoxaboroles characterized by the presence of a boronic acid hemiester with a phenolic ether and a nitrile. Crisaborole crystallizes into two polymorphs that differ in the conformation of the oxaborole ring. A cocrystal with 4,4'-bipyridine has been prepared and studied by X-ray crystallography.
