The pathogenic alterations in various cancer tissues depend on mutant BTK for cell proliferation and survival, and BTK is also overexpressed in a range of hematopoietic cells. Due to this, BTK is emerging as a potential drug target to treat various human diseases, and several reversible and irreversible inhibitors have been developed and are being developed. As a result, BTK inhibition, clinically validated as an anticancer treatment, is finding great interest in B\u2010cell malignancies and solid tumours. This study focuses on the design and synthesis of new oxindole sulfonamide derivatives as promising inhibitors of BTK with negligible off\u2010target effects. The most cytotoxic compounds with greater basicity were PID\u20104 (2.29\u00b10.52\u2005\u03bcM), PID\u20106 (9.37\u00b12.47\u2005\u03bcM), and PID\u201019 (2.64\u00b10.88\u2005\u03bcM). These compounds caused a selective inhibition of Burkitt's lymphoma RAMOS cells without significant cytotoxicity in non\u2010BTK cancerous and non\u2010cancerous cell lines. Further, PID\u20104 showed promising activity in inhibiting BTK and downstream signalling cascades. As a potent inhibitor of Burkitt's lymphoma cells, PID\u20104 is a promising lead for developing novel chemotherapeutics.<\/jats:p>","DOI":"10.1002\/cmdc.202300511","type":"journal-article","created":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T05:12:56Z","timestamp":1698901976000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Synthesis
