    Author: Hayat F, Moseley E, Salahuddin A, Van Zyl RL, Azam A.
    Journal: Eur J Med Chem; 2011 May; 46(5):1897-905. PubMed ID: 21377771.
    Abstract:
    A new series of chloroquinoline based chalcones were synthesized and evaluated for in vitro antiamoebic and antimalarial activities. The results showed that out of fifteen compounds, four were found to be more active against the Entamoeba histolytica; while one compound was moderatively active compared to the standard drug metronidazole (IC50=1.46 μM). In contrast, in vitro antimalarial activity against the chloroquine-sensitive (3D7) strain of P. falciparum indicated relatively low activity when compared to controls such as chloroquine and quinine (IC50=0.0065 μM and 0.14 μM, respectively). The toxicological studies of these compounds on human breast cancer MCF-7 cell line showed that all the compounds were non-toxic at the concentration range of 1.56-50 μM.
