Abstract A series of 3-fluro-4-alkoxyphenylalkanoic acids III was synthetized and their antiinflammatory activity and fibrinolytic capacity was evaluated. The suitable fluorinated derivative with better pharmacological profile than 3-chloro-4-benzyloxyphenylacetic acid (benzofenac) was selected. Experimental, biological activities of acids III were compared with those calculated by introducing the physico-chemical parameters into the formerly ...
