项目摘要

CONTE CENTER SUMMARY Neuroactive steroids (NAS) offer novel directions for psychiatric therapeutics. The prototypical NAS is allopregnanolone (AlloP), which under the formulation of brexanolone, has recently been approved by FDA for treatment of women with postpartum depression; a second, orally-active NAS has had a successful Phase 3 study for postpartum depression and a Phase 2B study for men and women with major depression. While AlloP is a potent and effective enhancer of GABAA receptors (GABAARs), it is not presently clear that the antidepressant effects of NAS are mediated solely by GABAergic effects, and recent data indicate that other mechanisms including effects on cellular stress and inflammatory pathways could also be involved. Members of our center have extensive experience studying the medicinal chemistry and mechanisms underlying the effects of AlloP-like NAS. In this Conte Center proposal we will leverage novel NAS compounds to probe varied molecular, synaptic, network and behavioral effects of NAS as clues to their therapeutic mechanisms and potential. Our center proposal is driven by unique NAS analogues synthesized in our Chemistry Core and involves three complementary and intertwined projects that will pursue three specific goals. First, we will test the hypothesis that selective actions of NAS on a class of GABAARs underlies effects on hippocampal electrical activity, network function and behavior in novel mouse lines and mouse models of postpartum and major depression. Second, we will examine the role of non-GABAA ion channels in mediating hippocampal and behavioral effects of NAS focusing on novel NAS that modulate NMDA glutamate receptors and low voltage activated calcium channels. These studies will use unique photoaffinity labeling approaches to elucidate sites of actions of NAS on NMDA receptors and other targets. Other studies will examine effects of NAS analogues on cellular function, neural network function, and behavior. Third, we will test the role of intracellular targets engaged by NAS on hippocampal circuits and behavior, focusing on the roles of neuroinflammation and cellular stress pathways. Our center is uniquely positioned to traverse the exploration of antidepressant NAS from molecules to sites of action and effects on dysfunctional circuits to identify potentially novel agents and targets for psychiatric therapeutic development.

CONTE中心摘要神经活性类固醇（NAS）为精神病治疗提供了新的方向。NAS的原型是别孕烯醇酮（AlloP），其在Brexanolone的剂型下，最近已被FDA批准用于治疗产后抑郁症的妇女;第二，口服活性NAS已经成功地产后抑郁症的3期研究和男性和女性重度抑郁症的2B期研究。虽然AlloP是GABAA受体（GABAAR）的有力且有效的增强剂，但目前尚不清楚 NAS的抗抑郁作用仅由GABA能作用介导，最近的数据表明，也可能涉及其它机制，包括对细胞应激和炎症途径的影响。我们中心的成员在研究药物化学和机制方面具有丰富的经验这是AlloP样NAS效应的基础。在本Conte Center提案中，我们将利用新型NAS 化合物来探测NAS的各种分子、突触、网络和行为效应，作为其治疗机制和潜力。我们的中心提案由独特的NAS类似物驱动在我们的化学核心合成，涉及三个互补和相互交织的项目，将追求三个具体目标。首先，我们将测试的假设，选择性行动的NAS对一类 GABAARs是影响海马电活动、网络功能和行为的基础，产后抑郁症和重度抑郁症的小鼠品系和小鼠模型。第二，我们将研究非GABAA离子通道介导NAS对海马和行为的影响调节NMDA谷氨酸受体和低压激活钙通道。这些研究将使用独特的光亲和标记方法来阐明NAS对NMDA受体的作用位点，其他目标。其他研究将检查NAS类似物对细胞功能，神经网络功能和行为。第三，我们将测试NAS参与的细胞内靶点对海马神经元的作用。电路和行为，侧重于神经炎症和细胞应激途径的作用。我们中心是独特的定位，以遍历探索抗抑郁剂NAS从分子到网站的行动以及对功能失调的回路的影响，以确定潜在的新药物和精神病治疗的靶点。治疗发展
