carbonic anhydrase vi

Mafenide hydrochloride (4-Aminomethylbenzenesulfonamide hydrochloride) is a sulfonamide that inhibits the enzyme carbonic anhydrase and is used as topical anti-infective, especially in burn therapy.

Chlorthalidone impurity G is a potential impurity found in commercial preparations of chlorthalidone that has moderate antihypertensive effects. Chlorthalidone is a thiazide-like diuretic that inhibits the Na+/Cl- cotransporter in the distal convoluted tubule of the kidney, which prevents reabsorption of sodium and chloride leading to a reduction in plasma volume and cardiac output. It also inhibits carbonic anhydrase (CA), including the isoforms CAVB, VII, IX, XII, and XIII (Kis = 2.8-23 nM) and, to a lesser extent, CAI, CAII, IV, VA, and VI (Kis = 138-1,347 nM), which may mediate its sustained vasodilatory activity. Dietary administration of chlorthalidone (8 mg per animal per day) reduces arterial hypertension and prevents or reduces ventricular hypertrophy induced by deoxycorticosterone acetate (DOCA) in salt-hypertensive rats. Formulations containing chlorthalidone have been used alone or in combination with other antihypertensive agents to lower arterial blood pressure and as adjuvants to address edema caused by cardiac or renal disorders.

Carbonic anhydrase inhibitor 11 (compound VI) is a potent, selective inhibitor of carbonic anhydrase, targeting CA II (Ki: 40 nM), CA IX (Ki: 39 nM), and CA XII (Ki: 900 nM).
