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

An economical, solvent-free, and metal-free method for peptidesynthesis via C–N bond cleavage using lactams has been developed. The method not only eliminates the need for condensation agents and their auxiliaries, which are essential for conventional peptidesynthesis, but also exhibits high atom economy. The reaction is versatile because it can tolerate side chains bearing a range of functional
A method of producing a polypeptide compound, wherein a peptide compound represented by formula (P) is obtained by inducing an amide formation reaction between an amino-protected lactam compound represented by formula (R1) and an amino acid ester or peptide ester compound represented by formula (R2).
The definitions for the reference signs in formulae (R1), (R2), and (P) are as set forth in the claims.
