Abstract

Malaria is an infectious disease caused by protozoa of the genus Plasmodium and then transmitted to humans through the Anopheles mosquito. One of the natural peptides found in previous studies is cyclic hexapeptide (Pro-Leu-Pipe-Trp- -Ala-Ile) from endophytic fungi isolated from the roots of Tritikum sp and produced pipecolisporin isolation which has been proven to have antimalarial activity. In this study the cyclic hexapeptide analogue pipecolisporin (Pro-Lys-Pipe-Trp- -Ala-Phe) has been successfully synthesized using a solid phase combination method (Solid Phase Peptide Synthesis) and a solution phase with a strategy of using Fmoc protective groups, solid phase buffers namely 2-chlorotrityl chloride resin and coupling reagents namely HATU, HOAt, and DIPEA. A linear hexapeptide compound has been formed which is indicated by the results of characterization using a mass spectrophotometer with an m/z value of 959.4612 at the ion peak and also a cyclic hexapeptide compound has been formed which is indicated by an m/z value of 741.4842 at the peak of the molecular ion [M+H].
