  4-Substituted thiophene- and furan-2-sulfonamides as topical carbonic anhydrase inhibitors

  摘要：

  A series of 4-substituted thiophene- and furan-2-sulfonamides was prepared and was found to possess nanomolar-level potency for inhibition of human carbonic anhydrase II in vitro. Selected examples from this group were further evaluated for their potential to act as topically effective ocular hypotensive agents in the ocular normotensive albino rabbit and the ocular alpha-chymotrypsinized rabbit. Solubility studies in water and pH 7.4 buffer were carried out to estimate the ability of compounds to be formulated in solution. The sensitization potential of key representative structures was determined by in vitro glutathione reactivity studies and guinea pig maximization testing.

  摘要：

  在乙酸酐中区域选择性地用硫酸磺化3-芳基噻吩和呋喃，得到相应的2,4-二取代的杂环。母体磺酰胺的苄胺衍生物可通过芳基酚的曼尼希反应，或通过采用自由基溴化后进行选择性氨解的顺序获得。该方法学提供了对各种区域选择性取代的杂环的容易获得的途径。

  Sulfonation of 3-aroylthiophenes and furans with sulfuric acid in acetic anhydride regioselectively affords the corresponding 2,4-disubstituted heterocycle. Benzylamine derivatives of the parent sulfonamides are obtained either by Mannich reaction of aryl phenols, or via a sequence employing free radical bromination followed by selective ammonolysis. This methodology provides ready access to a wide
