With the aim of overcoming gefitinib resistance, a series of novel quinazoline derivatives bearing an adamantyl group on the aniline ring were synthesized as potent epidermal growth factor receptor (EGFR) inhibitors. Most of these analogues are comparable to gefitinib in their ability to inhibit non-small cell lung cancer (NSCLC) cell lines, and several(More)
A series of novel azole-diphenylpyrimidine derivatives (AzDPPYs) were synthesized and biologically evaluated as potent EGFRT790M inhibitors. Among these analogues, the most active inhibitor 6e not only displayed high activity against EGFRT790M/L858R kinase (IC50=3.3nM), but also was able to repress the replication of H1975 cells harboring EGFRT790M mutation(More)
Adenine derivatives, in particular the scaffold bearing the acyclic nucleoside phosphonates (ANPS), possess significant antiviral and cytostatic activity. Till now, several effective adenine derivatives have been marketed for the treatment of HIV, HBV, CMV and other virus-infected diseases. These compounds are represented by tenofovir (PMPA), a medicine for(More)
Potential new EGFRT790M inhibitors comprised of structurally modified diphenylpyrimidine derivatives bearing a morpholine functionality (Mor-DPPYs) were used to improve the activity and selectivity of gefitinib-resistant non-small cell lung cancer (NSCLC) treatment. This led to the identification of inhibitor 10c, which displayed high activity against(More)
Treating patients suffering from EGFR mutant non-small cell lung cancer (NSCLC) with first-generation EGFR tyrosine kinase inhibitors (EGFR TKI) provides excellent response rates. However, approximately 60% of all patients ultimately develop drug resistance due to a second T790M EGFR TKI mutation. In this study, we report the novel molecule(More)
Because of the development of drug-resistance mutations, particularly the "gatekeeper" threonine(790)-to-methionine(790) (T790M) mutation in the ATP-binding pocket of the epidermal growth factor receptor (EGFR), the current generation of EGFR tyrosine kinase inhibitors lost their clinical efficacy. Recently, a large number of small-molecule inhibitors with(More)
BACKGROUND Although a number of agents can achieve high response in acquired immunodeficiency syndrome (AIDS) patients, safer and more active HIV inhibitors are still needed for the growing number of patients infected with resistant HIV virus strains. GW678248, is one of the most potent benzophenone derivatives, exhibiting high potency against a panel of(More)
