The alkylation reaction of 2,2'-diseleno and 4,4'-diseleno-bis(benzoic acid) derivatives in the presence of sodium borohydride and alkyl halides allowed the synthesis of various new o- and p-alkylselenenylated benzoic acid derivatives in good yields. The anti-inflammatory activity of selected selenide derivatives on granuloma induced by subcutaneous implantation of cotton pellets in Wistar rats was examined. Selenium derivatives 2a, 2c and 2e showed anti-inflammatory activity although to a lesser extent as compared to indomethacin, however they were found less toxic than the latter.
