- 요약Every few millimeters of brain tissue are anatomically and functionally distinct from one another, with clinically relevant differential expression of key drug targets, making for significant challenges in developing new pharmacotherapies for disorders of the nervous system. While many existent drugs have demonstrated efficacy for varied indications, issues such as potential toxicity, limited targeting efficiency, and the complexity of brain pathophysiology hinder effective treatment outcomes. In this dissertation, we present our work on 1) developing a novel noninvasive nanotechnology platform for the targeted delivery of small anesthetic compounds and 2) utilizing this technology to explore the electrophysiological and behavioral effects of ketamine in small animal models.In the first study, we employed solid phase microextraction, pharmacokinetic analysis, and histological assays to validate our novel drug delivery platform. By encapsulating ketamine within ultrasound-responsive drug nanocarriers, we achieved precise delivery of the compound to a targeted region of the brain upon activation with focused ultrasound. Our results demonstrated the efficacy and safety of this approach, providing evidence of ketamine localization at the site of delivery while minimizing systemic exposure within a small animal model. Additionally, we discuss the applications of this platform in understanding the effects of ropivacaine and other pharmacological compounds.We then leveraged the nascent technology in our second study to investigate whether the system could yield functionally significant bioeffects. Using pharmacokinetic, electrophysiological, and behavioral assays, we assessed the targeted effects of ketamine in a rodent model by delivering the compound to the medial prefrontal cortex (mPFC) and retrosplenial cortex (RsC)-two distinct brain regions known to mediate different functionally significant responses to ketamine. Our results provided evidence of ketamine's unique electrophysiological signatures recorded at each region and the corresponding unique behavioral effects. These findings further validated the precision of ultrasonic uncaging for localized drug delivery and provided insight into ketamine's regional specificity of response in the brain.Our work provides an essential tool to enhance our understanding of the mechanisms of anesthetic agents and ultimately, has the potential to inform the development of more effective treatment strategies for neuropsychiatric disorders.
