Arabilin is a chemical compound with the molecular formula C₂₈H₃₁NO₆. It was first isolated from the MK756-CF1 strain of Streptomyces in 2010. ^[1] Chemically, it contains a substituted γ-pyrone ring and a p-nitrophenyl group that is rarely found in nature.

Arabilin acts as an androgen antagonist, ^[1] and therefore has attracted research interest in its potential pharmacological use. ^{[2] [3]} A laboratory synthesis of arabilin has been reported. ^{[4] [5]}

Related compounds also isolated from Streptomyces include spectinabilin and SNF4435C. ^[1]
