Bis-alkylquinolines 1-6 were synthetized via Williamson reaction between 8-hydroxyquinaldine with different É, ù-dihaloalkanes. Structures of all the products were elucidated by spectroscopic analysis. Cytotoxic and antileishmanial activities of synthesized compounds were determinated on U-937 cells and L. (V) panamensis amastigotes, respectively. Compound 5, 1,9-bis[(2-methylquinolin-8-yl)oxy]nonane, was the most selective against axenic and intracellular amastigotes (EC50 = 11.3 and 22.6, ìg/mL), with selectivity indices greater than 17.7 and 8.8, respectively; which makes this compound promising for the developing of new leishmanicidal drugs.
