Synthesis and evaluation of osimertinib derivatives as potent EGFR inhibitors

Synthesis and evaluation of osimertinib derivatives as potent EGFR inhibitors
Osimertinib has been identified as a promising therapeutic drug targeting for EGFR T790M mutant non-small cell lung cancer (NSCLC). A new series of N-oxidized and fluorinated osimertinib derivatives were designed and synthesized. The cellular anti-proliferative activity, kinase inhibitory activity and the activation of EGFR signaling pathways of 1–6 in vitro were determined against L858R/T790M and wild-type EGFR, the antitumor efficacy in NCI-H1975 xenografts in vivo were further studied. Compound 2, the newly synthesized N-oxide metabolite in N,N,N′-trimethylethylenediamine side chain of osimertinib, showed a comparable kinase selectivity in vitro and a slightly better antitumor efficacy in vivo to osimertinib, making it valuable and suitable for the potential lung cancer therapy.
