Abstract

In 2014, we isolated kurahyne, an acetylene-containing lipopeptide, from a marine cyanobacterial assemblage of Lyngbya sp. Kurahyne exhibited growth-inhibitory activity against human cancer cells, and induced apoptosis in HeLa cells. However, its mode of action is not yet clear. To elucidate its mode of action, we carried out several cell-based assays, and identified the intracellular target molecule of kurahyne as sarco/endoplasmic reticulum Ca²⁺ ATPase (SERCA). In addition, we found that kurahyne inhibited the differentiation of macrophages into osteoclasts.
