Four inhibitors of human carbonic anhydrase II (hCA II) were designed based on the previously reported subnanomolar 1,3-oxazole-based sulfonamide inhibitors of the enzyme to incorporate primary and secondary amine functionality in the carboxamide side chain. The new hydrophilic compounds were found to inhibit the target isoform in sub-nanomolar to low nanomolar range with a good degree of selectivity to several other hCA isoforms. The hydrophilic character of these compounds is advantageous for intraocular residence time but not for corneal permeability which generally requires that a drug be sufficiently lipophilic. Two of the four compounds investigated, however, were found to exert comparable efficacy as 1% eye drops in PBS to that of the clin. used 2% dorzolamide (Trusopt) eye drops. This indicated that the absorption of the compounds may occur via alternative route across conjunctiva and sclera. In addition to this study using Ethyl oxalyl monochloride, there are many other studies that have used Ethyl oxalyl monochloride(cas: 4755-77-5Recommanded Product: 4755-77-5) was used in this study.
Ethyl oxalyl monochloride(cas: 4755-77-5) belongs to acyl chlorides. In the laboratory, acyl chlorides are generally prepared by treating carboxylic acids with thionyl chloride (SOCl2). The reaction is catalyzed by dimethylformamide and other additives.Recommanded Product: 4755-77-5
