Brartemicin is a trehalose-based inhibitor of tumor cell invasion produced by the actinomycete of the genus Nonomuraea. In order to explore the preliminary structure–activity relationship and obtain more potent inhibitors, a series of brartemicin analogs were synthesized through the Mitsunobu coupling of the secondary hydroxyls benzyl protected α,α-d-trehalose with benzoic acid derivatives, followed by modification

Brartemicin is a trehalose-based inhibitor of tumor cell invasion produced by the actinomycete of the genus Nonomuraea. In order to find more potent anti-invasive agents and study the structureâactivity relationships, a series of 19 brartemicin analogs were prepared via two synthetic routes from α,α-D-trehalose and evaluated for their anti-invasive activities. Compound 4f, 6,6â²-bis(2,3-dimethoxybenzoyl)-α,α-D-trehalose, was more potent than the natural brartemicin. It inhibited the invasion of murine colon 26-L5, colon carcinoma SW620, melanoma B16-BL6 and breast MDA-MB-231 cells with IC50 values of 0.15, 2.35, 4.12 and 2.61âμM, respectively. Analog 4p, 6,6â²-bis(3,4-dimethoxycinnamoyl)-α,α-D-trehalose, was as potent as brartemicin against invasion of murine colon 26-L5 carcinoma cells in vitro. The structureâactivity relationships of these novel trehalose-based compounds were summarized.
