Research on the genus Streptacidiphilus was mainly focused on the isolation and identification of new species, with relatively less emphasis on the study of secondary metabolites. A new aluminium-complex alumioxamine (3), and two known compounds desferrioxamine E (1) and ferrioxamine E (2) were isolated from the fermentation broth of Streptacidiphilus jiangxiensis CGMCC 4.1857. Their structures were elucidated by MS, IR, NMR and single crystal X-ray diffraction technologies. Structurally, compound 3 features aluminum(III) as the central atom, which is bonded to six oxygen atoms of the ligand, forming a hexadentate complex. Furthermore, in vitro cytotoxicity assays showed that compound 1 exhibited potential inhibitory activity against four human tumor cell lines (Hela, PANC1, A375 and MHCC-97H) at a concentration of 100 μmol/L with cell viability ranging from 4.8% to 66.4%.
