“…[32] Using these earlier optimized empirical parameters and considering the better adsorption, distribution, metabolism, and excretion (ADME) properties of small molecules that are needed for designing novel inhibitors toward E. coli premises, molecular docking studies of all the synthesized compounds were performed against the co-crystallized structure of RNAP domain of E. coli (PDB: 1DDE). [33,34] Using the site C catalytic residue, Arg 155 (druggable target), molecular docking studies of the synthesized compounds were done. We noticed a considerable binding free energy ranging from (À 4.8-5.4) Kcal/ mol for all the tested compounds, Table S22, SI.…”
