QSAR study on carbonic anhydrase inhibitors: aromatic/heterocyclic sulfonamides containing 8-quinoline-sulfonyl moieties, with topical activity as antiglaucoma agents.

Quantitative structure-activity-relationship (QSAR) study on aromatic/heterocyclic sulfonamides containing 8-quinoline-sulfonyl carbonic anhydrase (CA) inhibitors has been carried out topologically using first-order valence connectivity index ((1)chi(v)). Excellent results are obtained against all the three isozymes; CA I, II and IV of the zinc enzyme CA by using indicator parameters along with (1)chi(v).
