DESCRIPTION (provided by applicant): There is little doubt that we are in the midst of a worldwide epidemic of diabetes. Insulin resistance is recognized as a characteristic trait of the disease, defined by the inability to respond to normal circulating levels of insulin, and is usuall closely associated with obesity. Recent data suggest an inflammatory link between obesity and insulin resistance. We hypothesize that the induction of a counter-inflammatory program downstream of NFκB plays a key role in preserving energy storage, reducing energy expenditure and ensuring that insulin resistance is maintained during obesity. To this end, we have searched for inhibitors of the noncanonical IKK's TBK1 and IKKϵ, and plan to develop these as new therapeutic modalities. We will pursue this plan with three aims: 1) We will development analogs of the newly discovered inhibitor amlexanox with increased potency and metabolic stability, using both medicinal chemistry and structure- based design approaches; 2) We will develop novel inhibitors of IKKϵ and TBK1 that represent new chemical entities, driven by increased potency, improved pharmaceutical properties and in vivo activity in mouse models of obese type 2 diabetes; and 3) In order to support the clinical development of these new compounds, we will develop in vivo biomarkers for IKKϵ/TBK1 inhibition.

描述（由申请人提供）：毫无疑问，我们正处于糖尿病的全球流行之中。胰岛素抵抗被认为是糖尿病的一个特征，其定义为不能对正常循环水平的胰岛素作出反应，并且通常与肥胖密切相关。最近的数据表明肥胖和胰岛素抵抗之间存在炎症联系。我们假设NFκB下游的抗炎程序的诱导在保持能量储存、减少能量消耗和确保肥胖期间维持胰岛素抵抗方面起关键作用。为此，我们已经寻找了非经典IKK的TBK 1和IKK β的抑制剂，并计划将其作为新的治疗方式。我们将以三个目标来实施这一计划：1）我们将使用药物化学和基于结构的设计方法来开发新发现的抑制剂氨来诺的类似物，其具有增加的效力和代谢稳定性; 2）我们将开发代表新化学实体的IKK β和TBK 1的新型抑制剂，由增加的效力驱动，改善的药物特性和在肥胖2型糖尿病小鼠模型中的体内活性;和3）为了支持这些新化合物的临床开发，我们将开发用于IKK β 1/TBK 1抑制的体内生物标志物。
