Solution-phase parallel synthesis of substituted chalcones and their antiparasitary activity against Giardia lamblia
摘要:
A library of 25-membered chalcones was prepared by parallel synthesis. Substituted acetophenones and benzaldehydes were condensed using the Claisen-Schmidt base-catalyzed aldol condensation. Several chalcones showed in vitro antiparasitic activity against Giardia lamblia. The highest activity observed for the IC50 values were 12.72, 15.05 and 15.31 mu g/mL, respectively; these are potential leads for the development of antigiardial compounds. (C) 2009 Elsevier Ltd.
