Sulfonamide-incorporated bis(α-aminophosphonates) as promising carbonic anhydrase inhibitors: Design, synthesis, biological evaluation, and X-ray crystallographic studies.

A novel series of sulfonamide-incorporated bis(α-aminophosphonates) acting as effective carbonic anhydrase (CA, EC 4.2.1.

Inhibition Profiles of Some Novel Sulfonamide-Incorporated α-Aminophosphonates on Human Carbonic Anhydrases.

A series of hitherto unknown sulfonamide-incorporated α-aminophosphonate derivatives were synthesized through the one-pot, two-step FeCl-catalyzed coupling of 4-aminobenzenesulfonamide with the appropriate benzaldehydes and diethyl phosphite. The new sulfonamides inhibition studies were performed on four carbonic anhydrase isoforms, i.e.
