Abstract:
Background: Lung cancer has become the prominent cause of the cancer-related deaths
globally. More than 80 % of all lung cancers have been diagnosed with Non- Small Cell Lung
Cancer (NSCLC). The USFDA approved osimertinib to treat patients with metastatic T790M
EGFR NSCLC on a regular basis in March 2017. Recently, C797S mutation to osimertinib has
been reported, which indicates the need for structural modification to overcome the problem of
mutation.
Methods: In this bioinformatics study, we have evaluated the impact of various acrylamide as an
electrophilic warhead on the activity and selectivity of osimertinib.
Result: Osimertinib analouge 48, 50, 60, 61, 67, 75, 80, 86, 89, 92, 93, 116 and 124 were the most
active and selective compounds against T790M EGFR mutants compared to Osimertinib.
Conclusion: These compounds also showed less inclination towards WT-EGFR.
