Choomuenwai, Vanida and Schwartz, Brett D. and Beattie, Karren D. and Andrews, Katherine T. and Khokhar, Shahan and Davis, Rohan A. (2013) The discovery, synthesis and antimalarial evaluation of natural product ​based polyamine alkaloids. Tetrahedron Letters, 54 (38). pp. 5188-5191. ISSN 0040-4039


Bioassay-​guided fractionation of an antimalarial ext. derived from the fungus Ramaria subaurantiaca afforded the known polyamine alkaloid, pistillarin. Nine pistillarin analogs were synthesized via EDC-​mediated chem. and these compds. along with the previously reported natural product polyamines, ianthelliformisamines A-​C and spermatinamine, were evaluated against Plasmodium falciparum (3D7) parasites and a normal human cell line to det. parasite-​specific activity. Spermatinamine (IC50 0.23 μM) and pistillarin (IC50 1.9 μM) were the two most potent antimalarials identified during these studies.
