Abstract

Background: Breast Cancer (BC) is the most widely occurring disease in women. A massive number of women are diagnosed with breast cancer, and many lose their lives every year. Cancer is the leading cause of death worldwide, posing a formidable challenge to the current medication difficulties.

Objectives: The main objective of this study is to examine and explore novel therapy (PROTAC) and its effectiveness against breast cancer.

Methods: The literature search was conducted across Medline, Cochrane, ScienceDirect, Wiley Online, Google Scholar, PubMed, and Bentham Sciences from 2001 to 2020. The articles collected were screened, segregated, and selected papers were included for writing the review article.

Results and Conclusion: A novel innovation emerged around two decades ago that has great potential to overcome the limitations and provide future direction for the treatment of many diseases, which has presently not many therapeutic options available and are regarded as incurable with traditional techniques. That innovation is called PROTAC (Proteolysis Targeting Chimera), which can efficaciously ubiquitinate and debase cancer, encouraging proteins through noncovalent interaction. PROTACs constituted of two active regions isolated by a linker are equipped for eliminating explicit undesirable protein. It is empowering greater sensitivity to "drugresistant targets" and a more prominent opportunity to influence non-enzymatic function. PROTACs have been demonstrated to show better target selectivity contrasted with traditional small-molecule inhibitors. So far, the most investigation into PROTACs mainly concentrated on cancer treatment applications, including breast cancer. The treatment of different ailments may benefit the patients from this blossoming innovation.

Keywords: Breast cancer, novel therapy, protein degradation, PROTACs, ER-PROTAC, BET-PROTAC, BRD4-degrader.
