    • The present invention includes a system and method that uses optical LID biosensors to monitor in real time agonist-induced GPCR signaling events within living cells. Particularly, the present invention includes a system and method for using an optical LID biosensor to screen compounds against a target GPCR within living cells based on the mass redistribution due to agonist-induced GPCR activation. In an extended embodiment, the present invention discloses different ways for self-referencing the optical LID biosensor to eliminate unwanted sensitivity to ambient temperature, pressure fluctuations, and other environmental changes. In yet another extended embodiment, the present invention discloses different ways for screening multiple GPCRs in a single type of cell or multiple GPCRs in multiple types of cells within a single medium solution. In still yet another extended embodiment, the present invention discloses different ways to confirm the physiological or pharmacological effect of a compound against a specific GPCR within living cells.
    • 本发明包括使用光学LID生物传感器实时监测活细胞内激动剂诱导的GPCR信号事件的系统和方法。 特别地,本发明包括使用光学LID生物传感器基于由于激动剂诱导的GPCR活化导致的质量再分布来筛选活细胞内的靶GPCR的化合物的系统和方法。 在扩展实施例中,本发明公开了用于自参考光学LID生物传感器以消除对环境温度,压力波动和其他环境变化的不期望的灵敏度的不同方式。 在又一个扩展的实施方案中,本发明公开了在单一培养基溶液中的多种类型的细胞中单种类型细胞或多种GPCR筛选多种GPCR的不同方式。 在又一个延伸的实施方案中,本发明公开了确定化合物对活细胞内特异性GPCR的生理或药理作用的不同方式。

    • Drug discovery is a complex undertaking facing many challenges, not the least of which is a high attrition rate as many promising candidates prove ineffective or toxic in the clinic owing to a poor understanding of the diseases, and thus the biological systems, they target. Therefore, it is broadly agreed that to increase the productivity of drug discovery one needs a far deeper understanding of the molecular mechanisms of diseases, taking into account the full biological context of the drug target and moving beyond individual genes and proteins. The present methods rely on the use of label-free cellular assays, particularly the DMR index, to systematically display the mode of actions, the toxicity, and the target(s) and pathway(s) of any molecules.
    • 毒品发现是一项面临许多挑战的复杂工作,其中最重要的是高消耗率,因为许多有前途的候选人在诊所中证明无效或有毒,原因是对这些疾病的认识不足,从而导致其生物系统的目标。 因此,普遍同意,为了提高药物发现的生产力,需要更深入地了解疾病的分子机制,同时考虑到药物靶标的完整生物学背景,超越个别基因和蛋白质。 本方法依赖于使用无标记细胞测定法,特别是DMR指数来系统显示任何分子的作用模式,毒性以及靶标和途径。
