Abstract: 8-Tert.butyl-6-(1,1-dimethyl-2-hydroxyethyl)-4-oxo-4H-1-benzopyra- n-2-carboxylic acid (I) and its pharmaceutically acceptable derivs. are new cpds. (I) and its derivs. inhibit the release and/or activity of pharmacological mediators resulting from the in vivo combination of certain types of antibodies (e.g. reaginic antibodies) and specific antigens. They are useful for the treatment of asthma (e.g. allergic asthma or intrinsic asthma) hay-fever, eye disorders such as trachoma, urticaria, atopic eczema, and gastrointestinal allergies (esp. in children e.g. milk allergy). (I) are also useful for reducing blood uric acid levels and can therefore be used in the treatment of gout. (I) and its derivs. have the advantage of better absorption and greater activity than cpds. of similar structure after oesophageal administration. (I) and its derivs. may be obtd. by (a) treating 6,8-di-tert.butyl-4-oxo-4H-1-benzopyran-2-carboxylic acid or a deriv. thereof with microsomal enzymes of the liver (or another suitable tissue) of a mammal, (b) hydrolysing novel cpd. of formula (II) (where D is a gp. hydrolysable to -COOH, e.g. an ester, acid halide or cyano gp) or (c) cyclising novel cpd. of formula (III) (where A1 and A2 stand for the pair of gps. (i) -COCH2-COCOR" and -OM or (ii) -H and -O-C(COOM)CHCOOM R" being OM or a gp. hydrolysable to OM and M is H or an alkali metal). (I) obtd. may be converted into its pharmaceutically acceptable derivs. and derivs. obtd. may be converted into (I).
