A new series of diethyl (substituted phenyl/thiophen-2-yl)(quinolin-8-ylamino)methylphosphonates 4a-j of biological interest was synthesized by Kabachnik-Fields reaction. The title compounds were screened for their antimicrobial activity. Some of the compounds in the series exhibited promising antibacterial and antifungal activity. The newly synthesized compounds were subjected to molecular docking studies for the inhibition of the enzyme DNA Gyrase A, which is a new target for microbes (E. coli). The docking studies shown that 4b, 4c, 4e, 4g and 4h posses the highest binding energies compared to ciprofloxacin.
Keywords: α-Aminophosphonates, Antibacterial activity, Antifungal activity, CeCl3.7H2O, Molecular docking.
