  Optimization of Acetazolamide-Based Scaffold as Potent Inhibitors of Vancomycin-Resistant Enterococcus

  摘要：

  Vancomycin-resistant enterococci (VRE) are the second leading cause of hospital-acquired infections (HAIs) attributed to a drug-resistant bacterium in the United States, and resistance to the frontline treatments is well documented. To combat VRE, we have repurposed the FDA-approved carbonic anhydrase drug acetazolamide to design potent antienterococcal agents. Through structure-activity relationship optimization we have arrived at two leads possessing improved potency against clinical VRE strains from MIC = 2 mu g/mL (acetazolamide) to MIC = 0.007 mu g/mL (22) and 1 mu g/mL (26). Physicochemical properties were modified to design leads that have either high oral bioavailability to treat systemic infections or low intestinal permeability to treat VRE infections in the gastrointestinal tract. Our data suggest the intracellular targets for the molecules are putative alpha-carbonic and gamma-carbonic anhydrases, and homology modeling and molecular dynamics simulations were performed. Together, this study presents potential anti-VRE therapeutic options to provide alternatives for problematic VRE infections.

  摘要：

  通过使磺酰胺或5-氨基-1,3,4-噻二唑-2-磺酰胺与ω-氯链烷酰氯反应，然后用仲胺代替ω-氯原子，获得了一系列磺酰胺。已通过含有两个至五个碳原子的烷酰基-羧酰胺基连接体将掺有属于吗啉，哌啶和哌嗪环系统的杂环胺的尾巴连接至这些磺酰胺。测试了以此方式制备的新衍生物作为三种碳酸酐酶（CA，EC 4.2.1.1）同工酶，胞质同工酶CA I和II以及跨膜，肿瘤相关同工酶CA IX的催化域的抑制剂。在芳族和杂环磺酰胺系列中都检测到了几种低纳摩尔CA I和CA II抑制剂，

  Three new derivatives of 2-substituted 1,3,4-thiadiazole-5-sulfonamide have been synthesized. These compounds are 2-(3-chloropropionylamino)-1,3,4-thiadiazole-5-sulfonamide (1); 2-(2,2-dichloroacetylamino)-1,3,4-thiadiazole-5-sulfonamide (2); and 2-(3-phenylpropionylamino)-1,3,4-thiadiazole-5-sulfonamide (3). Inhibition effects of these compounds on carbonic anhydrase I and II have been investigated. By comparing I-50 and K-i values of the compounds, it has been found that compound 1 is a more potent inhibitor than acetazolamide (b) on carbonic anhydrase II. (C) 1997 Elsevier Science Ltd.
