Abstract: A series of novel fluorine-containing lupane triterpenoid acid derivatives with fluoroaromatic amide moieties at the C-28 position (1-8) or with 2-(fluoroacyl) cyclopentane-1,3-dione fragments at the C-3 position (9-18) of lupane skeleton was synthesized. A simple synthesis of novel lupane triterpenoid hybrids with 2-(fluoroacyl)-2-cyclopenten-1-one moieties was developed. An interaction of 2-acyl-3-chlorocyclopent-2-en-1-ones, obtained from corresponding cyclic beta-triketones, with methyl 3-amino-3-deoxybetulinate gave 3 beta-isomers (9-13) and 3 alpha-isomers (14-18) of target hybrids, which were isolated as individual compounds. Anti-inflammatory properties of selected synthesized compounds were studied in vivo using the histamine-, concanavalin A- and sheep erythrocytes immunization-induced mouse paw edema models. The antioxidant activity was investigated in vivo on the model of tetracycline-induced hepatitis. Majority of synthesized fluorine-containing lupane triterpenoid acid derivatives exhibited significant anti-inflammatory and antioxidant effects. Among studied compounds, 3 beta-hybrid 11 with 2-perfluorobutanoyl-2-cyclopenten-1-one moiety was the most potent bioactive compound.
