Novel dioxoacridine sulfonamide compounds were synthesized from reaction of cyclic 1,3-diketones, sulfanilamide (4-amino benzene sulfonamide) and aromatic aldehydes. The structures of these compounds were confirmed by using spectral analysis (IR, H-NMR, (13)C-NMR, and mass). Human carbonic anhydrase isoenzymes (hCA I and hCA II) were purified from(More)
Novel sulfonamide derivatives 6a-i, as new carbonic anhydrase inhibitors which candidate for glaucoma treatment, were synthesized from the reactions of 4-amino-N-(4-sulfamoylphenyl) benzamide 4 and sulfonyl chloride derivatives 5a-i with high yield (71-90%). The structures of these compounds were confirmed by using spectral analysis (FT-IR, (1)H NMR, (13)C(More)
The bisoctahydroxanthen-1,8-dione derivatives were synthesized effectively via p-dodecylbenzene sulfonic acid the catalysed cyclocondensation of cyclic 1,3-dicarbonyl compounds with 1,3- or 1,4-benzene dicarboxaldehydes in water. The products were obtained with yield ranged from 75 to 95%. The structures of compounds were characterized by FT-IR, 1H-NMR and(More)
