Recent advances in synthetic strategies of fourth-generation EGFR tyrosine kinase inhibitors under clinical trials for the treatment of resistant non-small cell lung cancer (NSCLC). (PubMed, Bioorg Chem) - "The present review summarizes recent advances in the synthetic strategies and biological profiles of fourth-generation EGFR-TK inhibitors currently undergoing clinical investigation for resistant Non-Small Cell Lung Cancer (NSCLC) to overcome the C797S mutation associated with Osimertinib. Representative clinical candidates, including TQB-3804, BPI-361175, BLU-945, BBT-176, BDTX-1535, QLH11811, HS-10375, and H002, are discussed with particular emphasis on synthetic route design, key intermediates, medicinal chemistry optimization, and pharmacological activity...In addition, advances in scaffold design, phosphine oxide incorporation, and conformationally optimized heterocyclic frameworks have contributed significantly to the development of next-generation mutant-selective inhibitors. Overall, this review provides a contemporary overview of synthetic innovations in fourth-generation EGFR inhibitor development and highlights emerging strategies for overcoming..."

MUCIN 1 confers inflammatory memory of tyrosine kinase inhibitor resistance in non-small cell lung cancer. (PubMed, Signal Transduct Target Ther) - "Our results further reveal that the MUC1-C-driven STAT1 inflammatory response promotes resistance of patient-derived (i) EGFR mutant NSCLC cells with MET amplification to the combination of osimertinib+MET TKIs, and (ii) EGFR(T790M/C797S) NSCLC cells to the 4th generation EGFR TKI TQB3804. Of clinical significance, we report that NSCLC cells dependent on MUC1-C for TKI resistance are druggable with an antibody-drug conjugate (M1C ADC) in vitro and in a PDX tumor model. These findings demonstrate that MUC1-C (i) is essential for TKI resistance of NSCLC cells by driving an inflammatory memory response and (ii) is a target for M1C ADC treatment of TKI-refractory NSCLCs."

A clinical review on third and fourth generation EGFR tyrosine kinase inhibitors for the treatment of non-small cell lung cancer. (PubMed, Bioorg Med Chem) - "This review delves into the current clinical status, efficacy, safety profiles, and regulatory approvals of third-generation EGFR TKIs, including Osimertinib, Lazertinib, Furmonertinib, Aumolertinib, Rezivertinib, Befotertinib, Sunvozertinib...Notable fourth-generation candidates such as TQB3804, BPI-361175, BDTX-1535, WJ13404, QLH11811, H002, HS-10375, BBT-207, JIN-A02, and HS-10504 are highlighted for their potential to overcome the C797S mutation...By evaluating the therapeutic potential and limitations of these EGFR TKIs, this review aims to guide future research in the management of EGFR-mutant NSCLC. This acts as guiding beacon for the strategic design and development of third and fourth generation EGFR-TK inhibitors to overcome the drug resistance hurdles in the development of EGFR-TK inhibitors."

.EGFR mutation mediates resistance to EGFR tyrosine kinase inhibitors in NSCLC: From molecular mechanisms to clinical research. (PubMed, Pharmacol Res) - "EGFR mutations, such as T790M and C797S, are the most common mechanism of EGFR-TKI resistance. Here, we discuss the mechanisms of EGFR-TKIs resistance induced by secondary EGFR mutations, highlight the development of targeted drugs to overcome EGFR mutation-mediated resistance, and predict the promising directions for development of novel candidates."
