It is reported in the literature that many compounds belonging to this class of compounds exhibit various pharmacological properties such as antibacterial, antifungal, antiviral, anticancer, inflammatory, antiglaucoma, and anticholinergic effects. Carbonic anhydrase (CA) enzymes play a critical role in pH regulation, long-term synaptic turnover and are therefore thought to be associated with such diseases as mental retardation, Alzheimer’s disease (AD) and Down syndrome. Studies have reported that there is an increase in the levels of hCA-I and hCA-II isoenzymes in AD. AD is a complex, multifactorial disorder, so therapy should probably address not only the cholinergic system but also additional systems. Based on these features, a series of novel substituted benzene sulfonamides were synthesized from 1,2,3-trimethoxy-5-methylbenzene. Sulfonyl chloride <strong>9</strong> was synthesized from the reaction of 1,2,3-trimethoxy-5-methylbenzene and excess chlorosulfonic acid.
