Abstract

The contribution of membrane-bound carbonic anhydrases (CAs) to hypoxic tumor growth and progression in cancer implicates cancer-associated CAs as a promising drug target for oncology. In this paper, we present a new class of sulfonamide-linked neoglycoconjugate that was designed to selectively target and inhibit the extracellular domains of the cancer-relevant CA isozymes. We describe the application of novel, yet straightforward, chemistry toward the synthesis of inhibitors that comprise both S-glycosyl sulfenamides and S-glycosyl sulfonamides. We also present the CA inhibition profile of our new neoglycoconjugates, more specifically a library of 30 compounds (3-32) that were designed to optimize both SAR (structure-activity relationship) and SPR (structure-property relationship) characteristics. We show that our approach produces neutral, water-soluble, and potent inhibitors (K(i)s in the low nanomolar range) that target cancer-associated CAs.
