Immunopharmacology Ligand
Comment: UFM24 is a flavone extracted from the Annonaceae Uvaria flexuosa [2]. It exhibits anti-inflammatory effects that are mediated by inhibition of PDE4 cAMP phosphodiesterases in neutrophils. The anti-inflammatory activities (inhibition of superoxide anion generation and elastase release from human neutrophils in response to fMLP) of seco-cyclohexenes and cyclohexenes isolated from Uvaria flexuosa leaves are reported by Hsu et al. (2016) [1].
