Targeting kinases with oncogenic driver mutations in malignancies with allosteric kinase inhibitors is a promising new treatment technique. EGFR inhibitors targeting the L858R/T790M/C797S mutation bearing thiazolidine-4-one scaffold were discovered, optimized, synthesized, and biologically evaluated. According to in silico and in vitro studies, compounds 6a and 6b resulted to be highly potent with IC50 values of 120 nM and 134 nM and good selectivity. Compound 6a displayed significant antioxidant activity, with a DPPH radical scavenging value of 92.15%. The potency of compounds was also compared with ADMET and molecular dynamics simulations study. A comparative simulation of model protein and protein-ligand complex in presence and absence of compound 6a has been carried out.Communicated by Ramaswamy H. Sarma.
