Inhibitors of 11 beta-hydroxysteroid dehydrogenase (11 beta-HSD1) show promise as drugs to treat metabolic disease and CNS disorders such as cognitive impairment. A series of 1,5-substituted 1H-tetrazole 11 beta-HSD1 inhibitors has been discovered and chemically modified. Compounds are selective for 11 beta-HSD1 over 11 beta-HSD2 and possess good cellular potency in human and murine 11 beta-HSD1 assays. A range of in vitro stabilities are observed in human liver microsome assays. (C) 2010 Elsevier Ltd. All rights reserved.

Emerging and resurging mosquito-borne flaviviruses are an important public health challenge. The increased prevalence of dengue virus (DENY) infection has had a significant socioeconomic impact on epidemic countries. The recent outbreak of Zika virus (ZIKV) has created an international public health emergency because ZIKV infection has been linked to congenital defects and Guillain-Barre syndrome. To develop potentially prophylactic antiviral drugs for combating these acute infectious diseases, we have targeted the host calcium/calmodulin-dependent kinase II (CaMKII) for inhibition. By using CaMKII structure-guided inhibitor design, we generated four families of benzenesulfonamide (BSA) derivatives for SAR analysis. Among these substances, N-(4-cyclohepty1-4-oxobuty1)-4-methoxy-N-phenylbenzenesulfonamide (9) showed superior properties as a lead CaMKII inhibitor and antiviral agent. BSA 9 inhibited CaMKII activity with an IC50 value of 0.79 mu M and displayed EC50 values of 1.52 mu M and 1.91 mu M against DENY and ZIKV infections of human neuronal BE(2)C cells, respectively. Notably, 9 significantly reduced the viremia level and increased animal survival time in mouse-challenge models.

Provided are novel benzenesulfonamide compounds that inhibit calcium/calmodulin-dependent protein kinase II (CaMKII) and pharmaceutical compositions containing the benzenesulfonamide compounds. Also provided are methods of using the benzenesulfonamide compounds to treat diseases or conditions that are associated with CaMKII activity, such as a flavivirus infection.
