Medicinal chemistry breakthroughs on ATM, ATR, and DNA-PK inhibitors as prospective cancer therapeutics
This review discusses the critical roles of Ataxia Telangiectasia Mutated Kinase (ATM), ATM and Rad3-related Kinase (ATR), and DNA-dependent protein kinase (DNA-PK) in the DNA damage response (DDR) and their implications in cancer. Emphasis is placed on the intricate interplay between these kinases,...

| Summary: | This review discusses the critical roles of Ataxia Telangiectasia Mutated Kinase (ATM), ATM and Rad3-related Kinase (ATR), and DNA-dependent protein kinase (DNA-PK) in the DNA damage response (DDR) and their implications in cancer. Emphasis is placed on the intricate interplay between these kinases, highlighting their collaborative and distinct roles in maintaining genomic integrity and promoting tumour development under dysregulated conditions. Furthermore, the review covers ongoing clinical trials, patent literature, and medicinal chemistry campaigns on ATM/ATR/DNA-PK inhibitors as antitumor agents. Notably, the medicinal chemistry campaigns employed robust drug design strategies and aimed at assembling new structural templates with amplified DDR kinase inhibitory ability, as well as outwitting the pharmacokinetic liabilities of the existing DDR kinase inhibitors. Given the success attained through such endeavours, the clinical pipeline of DNA repair kinase inhibitors is anticipated to be supplemented by a reasonable number of tractable entries (DDR kinase inhibitors) soon. |
