Resistance to Targeted Inhibitors
Several studies examined mechanisms of resistance or treatment response during kinase inhibition. In EGFR-mutant lung adenocarcinoma, SOS2 deletion reduced PI3K/AKT reactivation and sensitized cells to osimertinib, whereas HGF/MET-driven bypass contributed to resistance; patient-derived EML4-ALK models were used to evaluate sequential crizotinib, alectinib, lorlatinib, ceritinib, and brigatinib. Type II JAK2 inhibitor resistance in myeloproliferative neoplasms involved AXL and MAPK activation while JAK2-STAT3/5 remained suppressed, and ERK5 inhibition reduced viability in dabrafenib-resistant, but not vemurafenib-resistant, BRAF-mutant melanoma cells. In chronic myeloid leukemia, USP8 knockdown increased TKI sensitivity by suppressing EIF2S1 protein stabilization.

Clinical Targeted Therapy
Clinical studies evaluated iruplinalkib versus crizotinib in ALK-positive, ALK TKI-naive, locally advanced or metastatic NSCLC; amivantamab-lazertinib versus osimertinib as first-line treatment in previously untreated EGFR-mutated advanced NSCLC; pirtobrutinib versus investigatorβs choice of idelalisib/rituximab or bendamustine/rituximab in covalent BTK inhibitor-pretreated relapsed/refractory CLL/SLL; upadacitinib maintenance in Crohnβs disease; and ivarmacitinib with background conventional synthetic DMARDs in patients with active rheumatoid arthritis and an inadequate response to conventional synthetic DMARDs.

Computational Inhibitor Discovery
A group of studies uses virtual screening and molecular simulation to nominate kinase inhibitors before experimental testing. Machine-learning QSAR, docking, and molecular dynamics screened DrugBank compounds against PI3KΞ± in gastric cancer; virtual screening, docking, pharmacokinetics, and MM/PBSA identified the natural compounds (-)-balanol, digallic acid, and scutellarin as NEK7 candidates; and ZINC-library screening selected natural-product CDK8 binders after Lipinski, ADME, and pan-assay interference filters. AI and structure-based screening were also applied to TGFΞ²R1, while a language-model and graph-neural-network framework identified CDK9 inhibitor C1 with a reported IC50 of 1.2 nM and in vivo anti-leukemia activity.

Mechanism, Combination, And Safety
The papers also examine pathway mechanisms and clinically relevant drug effects, metabolism, and absorption. The p38Ξ± inhibitor BMS-582949 suppressed RANKL-induced osteoclastogenesis, F-actin ring formation, osteoclast-specific gene expression, MAPK/AKT signaling, and bone loss in ovariectomized mice, while dasatinib reduced bladder cancer proliferation and induced G1 arrest, apoptosis, and autophagy through PI3K/AKT/mTOR suppression. Dasatinib also reduced SAMHD1 phosphorylation, HIV-1 infection, and the inflammatory potential of macrophages; separate studies assessed osimertinib-associated QT prolongation and cardiac dysfunction, X-376 metabolism in human liver microsomes, and AI prediction of TKI malabsorption in settings such as proton-pump inhibitor use or bariatric surgery.
