Abstract Lung cancer is one of the most‐common malignant tumors while lung adenocarcinoma (LUAD) serves as major subtype cancer. The epidermal growth factor receptor‐tyrosine kinase inhibitors (EGFR‐TKIs) are an important choice in LUAD targeted therapies. However, EGFR‐TKI acquired resistance always happens, urging for further investigating and overcoming. We scRNA‐seq data from GSE149383 PRJNA591860 databases. identified typical tendency during progression LUAD. Furthermore, we investigate potential expression profiles, upstream transcription factors, interacting drugs with LUAD, participating resistance. According to databases, was “decrease early raise later” Day 0 11. Seven pairs factors target genes were explored including TFDP1‐RPA3, TFDP1‐EIF2S1, TFDP1‐COTL1, TFDP1‐CBX1, MYBL2‐STMN1, EZH2‐CYCS, BRCA1‐STMN1.

In nonsmall cell lung cancer (NSCLC), as well in other tumors, the targeted therapy is mainly represented by tyrosine kinase inhibitors (TKIs), small molecules able to target oncogenic driver alterations affecting gene encoding epidermal growth factor receptor (EGFR). Up now, several different TKIs have been developed. However, cells showed an incredible adaptive tumor response inhibition of sequentially mutated EGFR (EGFRM+), triggering need explore novel pharmacochemical strategies. This Review summarizes recent efforts development new reversible next-generation fight resistance against T790M and C797S mutations.

Background: Despite recent breakthroughs in cancer treatment, non-small cell lung (NSCLC) and breast remain major causes of death from all malignancies. The epidermal growth factor receptor (EGFR) is an important mediator the pathways involved proliferation, apoptosis, angiogenesis. Thus, its overexpression triggers several types cancer, including NSCLC cancer. Methods: In current study, we synthesized new pyrimidine-tethered compounds (chalcone derivative (B-4), pyrazoline-carbothioamide (B-9), pyrazoline-thiazole hybrids (BH1-7)). These were then tested for cytotoxicity against A549 MCF-7 cells. Results: Of these, B-4 displayed significant both cells (IC50 = 6.70 ± 1.02 µM MCF-7; IC50 20.49 2.7 A549) compared to standard agent lapatinib 9.71 1.12 18.21 3.25 A549). anticancer potential between Jurkat leukemic T peripheral blood mononuclear (PBMCs) (healthy) was found be selective. Mechanistically, 11.9% 10.2% treated with B-4, respectively, underwent apoptosis produced 46% EGFR inhibition at a concentration 10 μM.
