The secondary metabolome of the representative Roseobacter, Phaeobacter inhibens, was examined in response to algal sinapic acid. In addition to roseobacticides, sinapic acid induced the production of two new natural products, roseochelin A and B, which were characterized by NMR and X-ray crystallography. Functional assays showed that roseochelin B binds iron and is algaecidal against the algal host Emiliania huxleyi. It appears to be produced by a rarely observed combination of nonenzymatic and enzymatic transformations.

Roseochelin B，一种响应于藻类芥子酸的邻苯二酚玫瑰酸酯合成的藻类天然产物

响应于藻类芥子酸检查了代表性的玫瑰杆菌的次生代谢组份，Phieobacter inhibens。除了迷迭香外，芥子酸还可以诱导产生两种新的天然产物，即迷迭香素A和B，它们的特征在于NMR和X射线晶体学。功能分析表明，玫瑰螯素B与铁结合，对藻类寄主ili（Emiliania huxleyi）是杀藻的。它似乎是由很少见的非酶促转化和酶促转化结合产生的。
