A 3Dpharmacophoremodel predicting anticonvulsant activity was obtained for a series of 6,7‐dimethoxy‐1,2,3,4‐tetrahydroisoquinoline derivatives recently disclosed as a new class of noncompetitive AMPA receptor antagonists. The training set included 17 compounds with varying potency against audiogenic seizures in DBA/2 mice. The best statistical hypothesis, generated with the HypoGen module of Catalyst

In a previous paper we identified several 1-aryl-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline-2-sulfonamides that displayed inhibitory effects toward selected carbonic anhydrase isozymes at micromolar concentration. In order to deepen the structure-activity relationships (SARs) and identify novel compounds with improved activity, we synthesized a series of monomethoxy analogues of the previously investigated dimethoxy derivatives. The evaluation of biological profile has been focused on in vitro effects against several CA isoforms. The new monomethoxy derivatives showed higher hCA inhibitory effects against several isoforms compared to the dimethoxy analogues. Particularly, some of these compounds (e. g., 1b and 1h) showed low nanomolar K(I) values and excellent selectivity for hCA IX and hCA XIV versus hCA I and II inhibition. (C) 2011 Elsevier Ltd.
