  Targeting Hypoxic Tumor Cell Viability with Carbohydrate-Based Carbonic Anhydrase IX and XII Inhibitors

  摘要：

  Carbonic anhydrase (CA) enzymes, specifically membrane-bound isozymes CA IX and CA XII, underpin a pH-regulating system that enables hypoxic tumor cell survival and proliferation. CA IX and XII are implicated as potential targets for the development of new hypoxic cancer therapies. To date, only a few small molecules have been characterized in CA-relevant cell and animal model systems. In this paper, we describe the development of a new class of carbohydrate-based small molecule CA inhibitors, many of which inhibit CA IX and XII within a narrow range of low nanomolar K-i values (5.3-11.2 nM). We evaluate for the first time carbohydrate-based CA inhibitors in cell-based models that emulate the protective role of CA IX in an acidic tumor microenvironment. Our findings identified two inhibitors (compounds 5 and 17) that block CA IX-induced survival and have potential for development as in vivo cancer cell selective inhibitors.

• Inhibition of carbonic anhydrase isozymes with benzene sulfonamides incorporating thio, sulfinyl and sulfonyl glycoside moieties

  A series of benzene sulfonamides incorporating thio, sulfinyl or sulfonyl glycoside moieties were synthesized. These glycoconjugates were investigated for their ability to inhibit the enzymatic activity of four human carbonic anhydrases (hCA): isozymes I, II and tumour-associated isozymes IX and XII. The oxidation state of the sulfur in the carbohydrate tail moiety did not influence either enzyme inhibition potency or isozyme selectivity even though presenting opportunities for differing interactions with the target isozymes.
