摘要:

Neural Regen Res:蛋白降解靶向嵌合体技术:一种治疗中枢神经系统疾病的新策略

 

来自中国南通大学神经再生重点实验室的周松林团队,对于蛋白降解靶向嵌合体(PROTACs)技术的作用原理、最新进展、局限性及其在治疗中枢神经系统方面的应用进行了总结。文章将为利用PROTACs技术克服过去在研发药物以及神经系统疾病治疗方面遇到的难题提供思路。

既往多项研究从不同角度分析了PROTACs技术的优点,并利用此技术降解突变体BTK、mHTT、Tau等治疗脑卒中、阿尔茨海默病、帕金森病和亨廷顿病等神经系统疾病。

周松林等首先介绍了PROTACs的原理,然后关注PROTACs技术的最新进展,如降解多种突变BTK蛋白,从而治疗ibrutinib抵抗的非霍奇金淋巴瘤;使用小分子化合物iRucaparib-AP6降解PARP1;使用SD-36锁定STAT3;ADC技术平台对难治性HER2阳性乳腺癌的缓解;降解tau蛋白从而治疗阿尔兹海默症;通过dBET1降解BET蛋白,减缓小胶质细胞促炎反应等。文章同时从整体上指出PROTACs研究的优点与不足,为未来PROTACs的发展方向以及改进方法提供了新的思路。

这项成果撰写的文章发表在《中国神经再生研究(英文版)》杂志202110期。

Abstract: Neurological diseases such as stroke, Alzheimer’s disease, Parkinson’s disease, and Huntington’s disease are among the intractable diseases for which appropriate drugs and treatments are lacking. Proteolysis targeting chimera (PROTAC) technology is a novel strategy to solve this problem. PROTAC technology uses the ubiquitin-protease system to eliminate mutated, denatured, and harmful proteins in cells. It can be reused, and utilizes the protein destruction mechanism of the cells, thus making up for the deficiencies of traditional protein degradation methods. It can effectively target and degrade proteins, including proteins that are difficult to identify and bind. Therefore, it has extremely important implications for drug development and the treatment of neurological diseases. At present, the targeted degradation of mutant BTK, mHTT, Tau, EGFR, and other proteins using PROTAC technology is gaining attention. It is expected that corresponding treatment of nervous system diseases can be achieved. This review first focuses on the recent developments in PROTAC technology in terms of protein degradation, drug production, and treatment of central nervous system diseases, and then discusses its limitations. This review will provide a brief overview of the recent application of PROTAC technology in the treatment of central nervous system diseases.
