    Docking findings of the top-active synthesized compounds on dual kinase enzymes. Cartoon-surface 3D representation of the kinase highlighting the color-coded secondary structures; (yellow) Gly-rich loop, (red) hinge site, (magenta) activation loop, (cyan) catalytic motif, and (orange) gatekeeper residue; predicted binding modes of the 3f, 3h, and 3d compounds (blue sticks) with the redocked co-crystallized for docking protocol validation aligned co-crystallized as green sticks over the redocked blue sticked poses of EGFR's reversible inhibitor, Erlotinib (PDB ID: 4hjo) and VEGFR-2's potent reversible inhibitor, Sorafenib (PDB ID: 4asd). Only key residues of binding at a 4 Å radius around the ligand are shown as lines and polar contacts as black-dash lines.

    Co-detection of epidermal growth factor receptor <t>(EGFR)</t> and Ca 2+ level changes using the tetrahedral DNA nanostructure-based probe (TDN-EA) in vitro and <t>in</t> <t>cellular</t> . (A) The TDN-EA probe was incubated with EGFR protein (100 nM), Ca 2+ (100 nM), or their mixture for 1 h, and fluorescence changes were measured in vitro . Ex/Em = 488/520 nm, Ex/Em = 575/600 nm. (B) Confocal microscopy images display fluorescence changes of the TDN-EA probe in human embryonic stem cell-derived cardiomyocytes (hESC-CMs) pretreated with the EGFR inhibitor erlotinib hydrochloride (EH) (1 μM) and the Ca 2+ chelator ethylene glycol tetraacetic acid (EGTA) (100 nM) for 3 h, followed by angiotensin II (Ang II) stimulation for 24 h. (C) Fluorescence changes of the TDN-EA probe in hESC-CMs measured using a multifunctional plate reader. Cells were treated with EGFR inhibitors (gefitinib (GE), erlotinib (ER), or osimertinib (OS), 1 μM) and a Ca 2+ chelating agent (EGTA, 100 nM) for 3 h, followed by Ang II stimulation for 24 h. Ex/Em = 488/520 nm, Ex/Em = 575/600 nm. Data are presented as mean ± standard error of the mean (SEM). Statistical significance was determined by one-way analysis of variance (ANOVA) with Tukey's post hoc test. ns: not significant.

    Figure Lengend Snippet: Dose–response curves of the EGFR/VEGFR2 inhibition of compound 3f. IC 50 values were calculated using the non-linear regression dose–response curves in GraphPad prism. Values are expressed as mean ± SD of three independent trials.

    Article Snippet: All molecules were evaluated for their EGFR (BPS Bioscience Corporation Catalog #40321) and VEGFR-2 kinase inhibition using (BPS Bioscience Corporation catalog#40325) using ELISA kit (Enzyme-Linked Immunosorbent Assay).

    Docking findings of the top-active synthesized compounds on dual kinase enzymes. Cartoon-surface 3D representation of the kinase highlighting the color-coded secondary structures; (yellow) Gly-rich loop, (red) hinge site, (magenta) activation loop, (cyan) catalytic motif, and (orange) gatekeeper residue; predicted binding modes of the 3f, 3h, and 3d compounds (blue sticks) with the redocked co-crystallized for docking protocol validation aligned co-crystallized as green sticks over the redocked blue sticked poses of EGFR's reversible inhibitor, Erlotinib (PDB ID: 4hjo) and VEGFR-2's potent reversible inhibitor, Sorafenib (PDB ID: 4asd). Only key residues of binding at a 4 Å radius around the ligand are shown as lines and polar contacts as black-dash lines.
