项目摘要
Project Summary
Significant progress in human cancer therapy in the last decade has been driven by conceptionally new
approaches to treating cancer, including cancer immunotherapy, cancer nanotherapy (e.g. liposomal doxorubicin
or mRNA vaccines), or new types of biologics and small molecules. I propose to develop new approaches to
targeting protein-membrane interactions that could yield unprecedented methods to modulate cancer signaling
and generate useful paradigms for pharmacology at large. The role of protein-membrane and drug-membrane
interactions will be explored and targeted on various levels, each highly relevant to cancer pharmacology:
1. Cancer signaling, a hallmark of cancer, is largely dependent on the recruitment of kinases (e.g. PI3K or PKC)
and GTPases (e.g. RAS) to hotspots localized at the inner plasma membrane leaflet. I aim to develop bifunctional
inhibitors with the capacity to modulate these interactions as a new approach to target cancer signaling.
2a. Membrane-integrated receptors are also key players in cellular signaling (e.g. enzyme-linked receptors or
GPCRs). Recently, a number of pharmacophores have been discovered that target these proteins directly from
the intramembrane space. These `Intramembrane pharmacophores' first partition into the membrane and then
engage their target through lateral diffusion and entry. I aim to systematically modulate membrane exposed
pharmacophore sites to explore principles governing the action of these pharmacophores which in turn will aid
in the discoveries of new intramembrane pharmacophores.
2b. The majority of bioactive molecules acts on membrane proteins or intracellular targets and therefore needs
to partition into or cross biological membranes. I propose to use combinatorial chemistry to discover new
principles and chemical structures that modulate and privilege pharmacophores for cellular uptake. These will
be tested in live cells using high throughput assays as a holistic approach to covering all possible uptake
mechanisms on the first level of screening (e.g. endocytosis, transporters, passive diffusion).
Combined, the proposed research will provide important insights into the functional role of protein-
membrane interactions in cancer signaling and their vulnerability to small molecule-based modulation.
Each of the proposed directions has the potential to yield fundamentally new and unprecedented
approaches to targeting cancer and other diseases.
My mentor and collaborators have extensive experience in cancer pharmacology, drug discovery, and the
biophysical characterization of protein-membrane interfaces and will provide the training needed to conduct the
proposed research. They will also provide the mentorship needed to acquire all skills and preliminary data
needed for a successful transition to an independent career in cancer research.
项目摘要
在过去的十年里,人类癌症治疗的重大进步是由新的概念推动的
治疗癌症的方法,包括癌症免疫疗法、癌症纳米疗法(例如脂质体阿霉素
或信使核糖核酸疫苗),或新型生物制品和小分子。我建议开发新的方法来
靶向蛋白质-膜相互作用可能产生前所未有的方法来调节癌症信号
并为整个药理学提供有用的范例。蛋白质膜和药物膜的作用
将在不同的层面上探索和瞄准相互作用,每个层面都与癌症药理学高度相关:
1.癌症信号是癌症的一个标志,它在很大程度上依赖于激酶(如PI3K或PKC)的募集
和GTP酶(例如RAS)到位于内质膜小叶上的热点。我的目标是开发两种功能
具有调节这些相互作用的能力的抑制剂作为靶向癌症信号的新方法。
2A。膜结合受体也是细胞信号传递中的关键角色(例如,酶连接受体或
GPCRs)。最近,已经发现了一些直接针对这些蛋白质的药效团。
膜内间隙。这些“膜内药效团”首先分配到膜中,然后
通过横向扩散和进入来吸引他们的目标。我的目标是系统地调制曝光的薄膜
药效团网站,探索这些药效团的作用原理,这反过来将有助于
在新的膜内药物载体的发现中。
2B。大多数生物活性分子作用于膜蛋白或细胞内靶点,因此需要
隔开隔开或穿过生物膜我建议使用组合化学来发现新的
调节细胞摄取的药效团的原理和化学结构。这些遗嘱
在活细胞中进行测试,使用高通量分析作为覆盖所有可能摄取的整体方法
第一层筛选的机制(例如,内吞作用、转运蛋白、被动扩散)。
总而言之,这项拟议的研究将为了解蛋白质的功能作用提供重要的见解。
癌症信号转导中的膜相互作用及其对基于小分子的调制的脆弱性。
每一个提议的方向都有可能产生全新的、前所未有的结果
针对癌症和其他疾病的方法。
我的导师和合作者在癌症药理学、药物发现和
蛋白质-膜界面的生物物理特性,并将提供必要的培训
拟开展的研究。他们还将提供获得所有技能和初步数据所需的指导
成功地过渡到癌症研究的独立职业所需的。
