Synthesis and antiinflammatory activity of 2,6-bis(1,1-dimethylethyl)phenol derivatives.

The influence of 11 newly synthesized 2,6-bis(1,1-dimethylethyl)phenol derivatives substituted in the 4 position as measured on the carrageenan paw edema assay in Sprague-Dawley rats, was studied using indomethacin as a reference drug. Furthermore we studied the possible interference of few of these compounds on the calcium binding sites by using the specific ligand [3H]-PN 200-110 in "in vitro" experiments. As far as regard the antiinflammatory activity only the compounds 2b, 2j and 2k, dosed at 20 mg/Kg/os, exerted an inhibitory effect on paw edema which was practically equal, after 6 h, to that of indomethacin (approximately 30%) dosed at 2.5 mg/Kg. The compound 2k, however, showed, in comparison with indomethacin and the other new tested compounds, a longer lasting effect, reaching, after 8 h, a 56.7% inhibition of the edema. Finally the above mentioned compounds, when tested alone or in combination with nitrendipine, did not exert any displacing activity on [3H]-PN 200-110 binding to synaptosomal membranes. It is noteworthy however that compound 2e, which incidentally was inactive as antiinflammatory agent, showed a negative allosteric modulatory activity on the ability of nitrendipine to displace [3H]-PN 200-110 binding.[1]
