ANTIPROLIFERATIVE, ADME AND POTENTIAL IN SILICO G6PDH INHIBITORY ACTIVITY OF NOVEL 2-(1-BENZOFURAN-2-YL)-4-(5-PHENYL-4H-1, 2, 4-TRIAZOL-3-YL) QUINOLINE DERIVATIVES

Objectives: Synthesis of new 2-(1-benzofuran-2-yl)-4-(5-phenyl-4H-1, 2, 4-triazol-3-yl) quinoline and its derivatives for antiproliferative potential against cancer cells.Methods: The general methods were employed for the synthesis and the structures were confirmed by IR, 1H-NMR, 13C-NMR and mass spectral analysis. The antiproliferative activity was performed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and molecular docking study were performed by Auto Dock Tools. In silico Absorption-Distribution-Metabolism-Excretion-Toxicity (ADMET) study for the drug, likeliness was carried out on ACD/lab-2.Results: The compound 3l showed 44, 44, 38 and 37 % inhibition against MCF-7, HepG2, Colo205 and HeLa cell lines, respectively; whereas, the compounds 3i and 3j exhibited 49 and 42 % inhibition against MCF-7 cell line. The molecular docking study revealed that the compound 3i has the lowest binding energy (-8.60 Kcal mol-1), suggesting to be potentially best inhibitor of Glucose-6-phosphate dehydrogenase (G6PDH). The in silico ADME analysis also revealed that compound 3i does not violate any of the Lipinski rules of five and has the best stimulative human colonic absorption up to 95 %.Conclusion: The study reveals that the compounds containing benzofuran coupled nitrogen heterocycles are essential for activity as they possess excellent drug-like characteristics.Â

3-(2-Bromo­acet­yl)-6-fluoro-2H-chromen-2-one

The non-H atoms of the title compound, C11H6BrFO3, are essentially coplanar (r.m.s. deviation for all non-H atoms = 0.074 Å). In the crystal, the molecules are linked by C—H⋯O and C—H⋯Br inter­actions

4-4-(Heptyloxy)benzoyloxyphenyl 2-oxo-7-trifluoromethyl-2H-chromene-3- carboxylate

The title compound, C31H27F3O7, is a liquid crystal and exhibits enanti¬otropic SmA and nematic phase transitions. In the crystal, the the 2H-chromene ring system makes dihedral angles of 54.46 (17) and 7.79 (16)°, respectively, with the central benzene ring and 4-(hept¬yloxy)benzene ring. The three F atoms of the -CF3 group are disordered over two sets of sites, with an occupancy ratio of 0.62 (3):0.38 (3). The crystal structre features two pairs of C-H O hydrogen bonds, which form inversion dimers and generate R22(10) and R22(30) ring patterns. C-H O inter¬actions along [100] and C-H inter¬actions futher consolidate the packing, leading to a three-dimensional network
