Abstract

A series of 2,1,3- and 1,2,4-benzothiadiazine derivatives (BTDs) were synthesized and evaluated for their inhibitory activity versus enzymatic isoforms PDE3, PDE4 and PDE7. The compounds characterized by the 3,5-di-tert-butyl-4-hydroxybenzyl moiety at N1 position of 2,1,3-benzothiadiazine core (8, 13, 18), were found active and selective at micromolar level versus PDE4 and could be studied as new leads for the treatment of asthma and COPD (Chronic Obstructive Pulmonary Disease). The antioxidant activity evaluation on the same compounds highlighted 13 as the most significative. Molecular modelling studies gave further support to biological results and suggested targeted modifications so as to improve their potency.
