Ethyl [6-bromo-1-(4-fluorophenylmethyl)-4(1H)-quinolinon-3-yl]-4-hydroxy-2-oxo-3-butenoate 1 and [6-bromo-1-(4-fluorophenylmethyl)-4(1H)-quinolinon-3-yl)]-4-hydroxy-2-oxo-3-butenoïc acid 2 were synthesized as potential HIV-1 integrase inhibitors and evaluated for their enzymatic and antiviral activity, acidic compound 2 being more potent than ester compound 1. X-ray diffraction analyses and theoretical calculations show that the diketoacid chain of compound 2 is preferentially coplanar with the quinolinone ring (dihedral angle of 0-30°). Docking studies suggest binding modes in agreement with structure-activity relationships.
