It is active against SV40 tumour cells, and inhibits the growth of solid tumour-derived cell lines such as DLD-1 human colon cancer cells with increased cells in G1 and S phases. It has a role as an antimicrobial agent, an antineoplastic agent and a bacterial metabolite. It is a macrolide, a cyclic hemiketal, a member of oxanes, a secondary alcohol, an enoate ester, an alpha,beta-unsaturated monocarboxylic acid and an ether."}]
