چکیده

Non-small cell lung cancer (NSCLC) has evolved into the deadliest in present scenario. The progression of NSCLC is mainly due to dysregulation tyrosine kinase family's epidermal growth factor receptor (EGFR). Thus, EGFR been widely studied as a major target treatment NSCLC, but lack selectivity and drug resistance limit use existing therapeutic agents. Considering urgent necessity for advanced development inhibitors, we have implemented three-dimensional structure-activity relationship (3D QSAR), molecular docking, MMGBSA studies on series pyrimidine derivatives. In 3D QSAR, comparative field analysis model (CoMFA) was obtained with correlation coefficient (r<sup>2</sup>) = 0.698, cross-validated (q<sup>2</sup>) 0.541, predictive r<sup>2</sup> (r<sup>2</sup><sub>pred</sub>) 0.509. similarity indices (CoMSIA) also displayed similar results r<sup>2 </sup>= 0.72, q<sup>2 0.586, r<sup>2</sup><sub>pred</sub>= 0.495. statistical parameters fulfill acceptability criteria models. Docking revealed binding interactions derivatives double mutant EGFR<sup>L858R/T790M</sup>. scores top two selected compounds 29 34 were 92.99 92.13, respectively. Analyzing QSAR contour plots docking reviewed some important structural attributes <sup>L858R/T790M</sup> selective which directed designing new molecules. designed showed good activity exhibited higher EGFRL858R/T790M than reference ligand gefitinib. Moreover, evaluate hits from compounds, (Molecular Mechanics-Generalized Born Surface Area) performed, that compound (N7) affinity EGFR<sup>L858R/T790M</sup> (dG -68.59 kcal/mol) compared other compounds. Further, silico ADME predictions drug-likeness this work will guide researchers future developments inhibitors.

2D-QSAR and docking studies of 4-anilinoquinazoline derivatives as epidermal growth factor receptor tyrosine kinase inhibitors

Introduction: Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor derivatives play an important role in the treatment of cancer. We aim to construct 2D-QSAR models using various chemometrics using 4-anilinoquinazoline-containing EGFR TKIs. In addition, the binding profile of these compounds was evaluated using a docking study. Materials and Methods: In this study, 122 compounds of...

Identification of the Structural Features of Guanine Derivatives as MGMT Inhibitors Using 3D-QSAR Modeling Combined with Molecular Docking.

DNA repair enzyme O⁶-methylguanine-DNA methyltransferase (MGMT), which plays an important role in inducing drug resistance against alkylating agents that modify the O⁶ position of guanine in DNA, is an attractive target for anti-tumor chemotherapy. A series of MGMT inhibitors have been synthesized over the past decades to improve the chemotherapeutic effects of O⁶-alkylating agents. In the pres...

In Silico Screening Studies on Methanesulfonamide Derivatives as Dual Hsp27 and Tubulin Inhibitors Using QSAR and Molecular Docking

The expression of heat shock protein 27 (Hsp27) as a chaperone protein, is increased in response to various stress stimuli such as anticancer chemotherapy. This phenomenon can lead to survive of the cells and causes drug resistance. In this study, a series of methanesulfonamide derivatives as dual Hsp27 and tubulin inhibitors in the treatment of cancer were applied to quantitative structure–act...

Novel Approach Synthesis, Molecular Docking and Cytotoxic Activity Evaluation of N-phenyl-2,2-dichloroacetamide Derivatives as Anticancer Agents

Dichloroacetate (DCA) as a small, cheap and available anticancer agent, is a pyruvate mimetic compound that stimulates the activity of pyruvate dehydrogenase (PDH) enzyme through inhibition of pyruvate dehydrogenase kinases (PDHK1-4). DCA turns on programed cell death (apoptosis) which suppressed in tumor cells and therefore inhibits tumor growth. DCA also interferes with the glucose uses of ca...
