A series of N-1,3 disubstituted 2,1,3-benzothiadiazine derivatives (BTDs) were synthesized and evaluated for their inhibitory activity versus enzymatic isoform PDE4 extracted from U937 cell line. Some of the tested compounds showed a high PDE4 inhibitory activity at 100:μM and the IC50 value of the most interesting terms were evaluated. The structure-activity relationships of these compounds showed that the 3,5-di-tert-butyl-4-hydroxybenzyl moiety at N-1 position is important to obtain activity at micromolar level as previously reported. For the same compounds the antioxidant activity were evaluated highlighting 14 as the most significative one. The introduction of other bulky substituents in N-1 position is detrimental.

In order to synthesize N-isopropyl-N'-o-carbomethoxyphenylsulphamide, sulphuric chlorohydrin is reacted with a pyridic base between -10° and 50° C., after which anthranilic acid methyl ester is firstly added at 0°-60° C., followed by isopropylamine at 0°-
