A number of isothiazolo[4,5-b]carbazole derivatives were prepared via a Diels Alder approach involving thermally induced indole-2,3-quinodimethane intermediates. Preliminary biological tests revealed a CSK-3 beta kinase inhibitor (29) and some free NH group containing compounds (17d, 19c, 29) displayed selective human carbonic anhydrase I inhibitory activities.
