Kinetic and thermodynamic insights into interaction of erlotinib with epidermal growth factor receptor: Surface plasmon resonance and molecular docki…
2020
Abstract Epidermal growth factor receptor (EGFR) plays an important role in cell proliferation at non-small cell lung cancer (NSCLC). Therefore, targeted therapy of cancer via this kind of receptor is highly interested. Small molecule drugs such as erlotinib and gefitinib inhibit EGFR tyrosine kinase and thus suppress cell proliferation. At this paper, erlotinib interaction with EGFR on the cell surface was studied via surface plasmon resonance (SPR) and molecular docking methods. Kinetic parameters indicated that erlotinib affinity toward EGFR was increased through increment of temperature. The thermodynamic analysis showed that van der Waals and hydrogen binding forces play a major role i…
Surface plasmon resonance signal enhancement based on erlotinib loaded magnetic nanoparticles for evaluation of its interaction with human lung cance…

Abstract Surface plasmon resonance (SPR) sensor provides a very useful tool based on its label-free, real-time monitoring and low price properties. However, measurement of small molecules and extremely diluted analytes is difficult and therefore, signal enhancement is required. In the present study, signal enhancement of erlotinib conjugated magnetic nanoparticles (erlotinib-MNPs) compared to erlotinib was evaluated via their interaction with overexpressed epidermal growth factor receptor on human lung cancer cells (A549 cell line) surface using SPR sensor at three temperature levels. The attained results showed an average signal amplification of about 2.5-fold for MNP-erlotinib interaction…
