8-Acyl and 8-sulfonylamidowogonin analogues were synthesized as potential anti-inflammatory agents. Nitration of 5,7-dihydroxyflavone (chrysin) followed by methylation of phenol groups and reduction of nitro group yielded 8-aminowogonin analogues. Acylation and sufonylation of 8-aminowogonin followed by demethylation reactions gave the title compunds. The synthesized wogonin analogues showed much reduced inhibitory activity on prostaglandin $E_2\;(PGE_2)$ production.
