HIV-1 integrase (IN) inhibition of a novel series of quinoline derivatives was investigated. The compounds were designed on the basis of quinoline molecular scaffolds that attempt to mimic the basic naphtyridine motif of the L-870810 HIV-1 IN inhibitor. It appeared that the IN inhibition of the novel compounds was limited by the electroacceptor substitution within quinoline. Although the compounds studied here indicate structural similarity to L-870810, they are much less efficient than this compound. This can be explained by differences in conformations and apparent magnesium complexing ability in the naphtyridine and quinoline based amides.
