Inhibition of albumin denaturation and anti-inflammatory activity of acetamido [(phenyl-4'-yl)-oxymethyl)]2-(p-substituted phenylamino)-1,2,4-triazoles and -1,3,4-thiadiazoles.

ABSTRACT

Acetamido [(phenyl-4'-yl)-oxymethyl)]-2-(p-substituted-phenylamino)-1,2,4-tr iazoles (4a-4d) and 1,3,4-thiadiazoles (5a-5d) inhibited the thermal denaturation of bovine serum albumin. As protein denaturation is implicated in inflammation, some compounds which showed good inhibition of denaturation were tested in vivo for anti-inflammatory activity by carrageenan induced edema in the rat paw. Although there was no complete correlation, compounds which showed good inhibition of denaturation also showed significant anti-inflammatory activity.
