among them linear di-, tri-, tetra- and pentapeptides and their cyclic analogs. In an attempt to find dipeptides with antimalarial activities we show that linear and cyclicdipeptides, the latter known as diketopiperazines, still retain the fundamental core to preserve antimalarial activity. Thirteen lineardipeptides and ten diketopiperazines were investigated. Eight lineardipeptides showed IC50

2,5-Dioxopiperazines with symmetrical as well as unsymmetrical substituent pattern can be obtained via 2,2-bis(trifluoromethyl)-1,3-oxazolidin-5-ones, and 2,5-dioxomorpholines via 2,2-bis-(trifluoromethyl)-1,3-dioxolan-4-ones, respectively.
