Pyrazole and Pyrazoline-Based EGFR TK Inhibitors: A Review Study Emphasizing Structure-Activity Relationship (SAR).

Unusual cell growth patterns, metastasis (the spread of tumors to other parts of the body), and potential death are all hallmarks of cancer. Research in oncology clearly shows that abnormalities in EGFR expression directly contribute to uncontrolled cell growth and division, resulting in the development of carcinomas. People with cancer have developed resistance due to mutations in several EGFR-associated genes. Tyrosine kinase inhibitors (TKIs) and other cancer treatments must, therefore, undergo continuous improvement. Currently, fourth-generation tyrosine kinase inhibitors (TKIs) that act allosterically against the C797S mutation are the most widely used class of medications that target EGFR mutations. To help researchers better understand how to optimize pyrazole and pyrazoline-based derivatives as antiproliferative agents, this review summarises the work done in the last fifteen years on different anti-cancer agents representing 31 most potential compounds along with their activity characteristics, with a particular emphasis on the structure-activity relationship (SAR) of possible pyrazole and pyrazoline derivatives as EGFR tyrosine kinase inhibitors.
