Several novel series of nitrile-containing fluoroquinolones with weakly basic amines are reported which have reduced potential for hERG (human ether-a-go-go gene) channel inhibition as measured by the dofetilide assay. The new fluoroquinolones are potent against both Gram-positive and fastidious Gram-negative strains, including Methicillin resistant Staphylococcus aureus and fluoroquinolone-resistant
series of 7-[3-(1-aminoalkyl and 1-aminocycloalkyl)-1-pyrrolidinyl] quinolones have been prepared and their biological properties evaluated. Among them, 1-(S)-aminoalkyl derivatives exhibited potentantibacterialactivities against gram-positive and gram-negative organisms. They had moderate lipophilicity and high aqueous solubility compared to their aminomethyl counterparts; e.g., the 3-(1-aminoethyl)-1-pyrrolidinyl
