Published: November 2018

Hoshinoamides A (1) and B (2), new acyclic lipopeptides, were isolated from the marine cyanobacterium Caldora penicillata. Their structures were elucidated by spectroscopic analyses and degradation reactions. Hoshinoamides A (1) and B (2) did not exhibit any cytotoxicity against HeLa cells at 10 μM, but inhibited the in vitro growth of the malarial parasite Plasmodium falciparum (IC = 0.52 and 1.0 μM, respectively).
