Analysis of inhibitor binding in influenza virus neuraminidase

Abstract: Abstract2,3-didehydro-2-deoxy-N-acetylneuraminic acid (DANA) is a transition state analog inhibitor of influenza virus neuraminidase (NA). Replacement of the hydroxyl at the C 9 position in DANA and 4-amino-DANA with an amine group, with the intention of taking advantage of an increased electrostatic interaction with a conserved acidic group in the active site to improve inhibitor binding, significantly reduces the inhibitor activity of both compounds. The three-dimensional X-ray structure of the complexes of … Show more

“…This method improves the time of calculation than if all of trajectories saved were calculated. The results are known similar to other studies that calculated the binding free energy of NA-inhibitor complexes with different approaches [25,26]. In the explicit solvation systems, complex molecules calculated without any implicit solvation energetic contribution while in the implicit solvation, the calculation executed with the addition of GBMV implicit solvation energy.…”

“…The results show the values of -1.37 kcal/mol and 17.97 kcal/mol for HPAI and LPAI, respectively. Compared by other studies [25,26,31], the calculation with GBMV is at their results range (-21.7 kcal/mol to 7.3 kcal/mol). This is indicate that our…”

“…Eleven receptor-ligand complex structures were used as starting points for the neuraminidase calculations (PDB identifiers 1BJI, 1F8B, 1F8C, 1F8D, 1F8E, 1L7F, 1MWE, 1NNC, 2QWI, 2QWJ, 2QWK). [15][16][17][18][19][20] Cocrystal structures were prepared using Pfizer in-house software that automates standard protein preparation tasks. Manual preparation or publicly available tools can also be used.…”
