Third-generation epidermal growth factor receptor (EGFR) inhibitors are still the main drugs for the treatment of advanced non-small cell lung cancer (NSCLC), and these drugs have achieved remarkable clinical efficacy. However, there are still many patients suffering from drug-resistant mutations and drug side effects caused by NSCLC. In this study, guided by the molecular simulation, we applied a structure-based drug design strategy (SBDD) and optimized the structure to obtain a series of potent and selective EGFR inhibitors. The most potent compound 18e demonstrated excellent kinase inhibitory activity and selectivity for EGFR double mutants and the IC value reached nanomolar level. The selectivity of 18e against wild-type EGFR was near to 200-fold. In addition, compound 18e also inhibited H1975 cells proliferation at G2/M phase and induced apoptosis at a concentration of 0.25 μM, which makes it more valuable for potential lung cancer research.

Target cyclooxygenase 2 (COX-2) and 5-lipoxygenase (5-LOX) inhibitors; 5-([2,5-Dihydroxybenzyl]amino)salicylamides (Compounds 1-11) were examined for potential anticancer activity, with a trial to assess the underlying possible mechanisms. Compounds were assessed at a single dose against 60 cancer cell lines panel and those with the highest activity were tested in the five-dose assay. COMPARE analysis was conducted to explore potential mechanisms underlying their biological activity.

Background: The effect of lowering uric acid levels on renal function in patients with diabetic kidney disease remains unclear. Previous randomized controlled trials (RCTs) have reported conflicting results regarding the effects of xanthine oxidase inhibitors on renal function. This study aimed to examine the renoprotective effects of xanthine oxidase inhibitors (febuxostat and topiroxostat) in patients with diabetic kidney disease.

Proton pump inhibitors (PPI), relatively often used after RYGB, are associated with reduced calcium absorption. We have studied the long-term impact of PPI upon calcium homeostasis among RYGB patients.

To investigate the impact of SMARCA4 mutations on the outcomes of patients with advanced lung adenocarcinoma with epidermal growth factor receptor (EGFR) mutations. In the Memorial Sloan Kettering Cancer Center (MSK) MetTropism study, 960 patients with advanced EGFR-mutated lung adenocarcinoma were screened and included in the MSK cohort, composing of 313 males and 647 females, with a median [(, )] age of 64 (56, 72) years. A retrospective analysis was conducted on the data of 178 patients with advanced EGFR-mutated lung adenocarcinoma who received EGFR tyrosine kinase inhibitors (TKIs) treatment in the Department of Oncology, the First Affiliated Hospital of Nanjing Medical University, from January 2018 to December 2022.

Introduction: Amivantamab, an EGFR-MET bispecific antibody, is approved for multiple indications in EGFR-mutated advanced non-small cell lung cancer (NSCLC) as monotherapy or combined with other agents. Intravenous amivantamab is associated with a 67% infusion-related reactions (IRR) rate.
Methods: The phase 2 SKIPPirr study (NCT05663866) enrolled patients with EGFR-mutated (Ex19del/L858R) advanced NSCLC after progression on osimertinib and platinum-based chemotherapy who received intravenous amivantamab plus oral lazertinib (amivantamab-lazertinib), a third-generation tyrosine kinase inhibitor.
