Furopyridine Derivatives as Potent Inhibitors of the Wild Type, L858R/T790M, and L858R/T790M/C797S EGFR.

The treatment of patients with nonsmall cell lung cancer (NSCLC) using epidermal growth factor receptor (EGFR) inhibitors is complicated by drug-sensitive activating L858R/T790M and L858R/T790M/C797S mutations. To overcome drug resistance, a series of furopyridine (PD) compounds were virtually screened to identify potent EGFR inhibitors using molecular docking and molecular dynamics (MD) simulations based on the solvated interaction energy (SIE) method. Several PD compounds identified from virtual screening demonstrated the potential to suppress both wild-type and mutant forms of EGFR, with IC values in the nanomolar range.

Phthalazine Sulfonamide Derivatives as Carbonic Anhydrase Inhibitors. Synthesis, Biological and in silico Evaluation.

Carbonic Anhydrases (CAs) are a large family of zinc metalloenzymes that catalyze the reversible hydration of carbon dioxide involved in several biological processes. They show a wide diversity in tissue distribution and their subcellular localization. Twenty-two novel phthalazine derivatives were designed, synthesized, and evaluated against four human isoforms: hCA I, hCA II, hCA IX, and hCA XII.

Discovery of furopyridine-based compounds as novel inhibitors of Janus kinase 2: In silico and in vitro studies.

Janus kinase 2 (JAK2), one of the JAK isoforms participating in a JAK/STAT signaling cascade, has been considered a potential clinical target owing to its critical role in physiological processes involved in cell growth, survival, development, and differentiation of various cell types, especially immune and hematopoietic cells. Substantial studies have proven that the inhibition of this target could disrupt the JAK/STAT pathway and provide therapeutic outcomes for cancer, immune disorders, inflammation, and COVID-19. Herein, we performed docking-based virtual screening of 63 in-house furopyridine-based compounds and verified the first-round screened compounds by in vitro enzyme- and cell-based assays.

Discovery of Novel EGFR Inhibitor Targeting Wild-Type and Mutant Forms of EGFR: In Silico and In Vitro Study.

Targeting L858R/T790M and L858R/T790M/C797S mutant EGFR is a critical challenge in developing EGFR tyrosine kinase inhibitors to overcome drug resistance in non-small cell lung cancer (NSCLC). The discovery of next-generation EGFR tyrosine kinase inhibitors (TKIs) is therefore necessary. To this end, a series of furopyridine derivatives were evaluated for their EGFR-based inhibition and antiproliferative activities using computational and biological approaches.

Design, Synthesis and Pharmacological Evaluation of Novel C,C-Quinoxaline Derivatives as Promising Anxiolytic Agents.

A new series of quinoxaline derivatives, -, were synthesized and their anxiolytic potential was evaluated in vivo using elevated plus maze (EPM), open field (OF) and light-dark box (LDB) techniques. According to the results of the EPM, four active compounds were found in , , , . Their anxiolytic properties were confirmed in terms of LDB and the most active was compound .

Experimental and In Silico Evaluation of New Heteroaryl Benzothiazole Derivatives as Antimicrobial Agents.

In this manuscript, we describe the design, preparation, and studies of antimicrobial activity of a series of novel heteroarylated benzothiazoles. A molecular hybridization approach was used for the designing compounds. The in vitro evaluation exposed that these compounds showed moderate antibacterial activity.
