ABSTRACT
Fusarithioamide B (6), a new aminobenzamide derivative with unprecedented carbon skeleton and five known metabolites stigmast-4-ene-3-one (1), stigmasta-4,6,8(14),22-tetraen-3-one (2), p-hydroxyacetophenone (3), tyrosol (4), and fusarithioamide A (5) were separated from Fusarium chlamydosporium EtOAc extract isolated from Anvillea garcinii (Burm.f.) DC. leaves (Asteraceae). The structure elucidation and completeassignment of the isolated metabolites were performed mainly by the aid of various NMR and MS data. Fusarithioamide B (6) has been assessed for antibacterial and antifungal activities towards various microbial strains by disc diffusion assay. It exhibited selective antifungal activity towards C. albicans (MIC 1.9⯵g/ml and IZD 14.5â¯mm), comparing to clotrimazole (MIC 2.8⯵g/ml and IZD 17.9â¯mm). Also, it possessed high antibacterial potential towards E. coli, B. cereus, and S. aureus compared to ciprofloxacin. Furthermore, 6 was tested for the in vitro cytotoxic effect against KB, HCT-116, BT-549, MCF-7, SKOV-3, and SK-MEL cell lines. It had selective and potent effect towards BT-549, MCF-7, SKOV-3, and HCT-116 cell lines with IC50s 0.09, 0.21, 1.23, and 0.59⯵M, respectively compared to doxorubicin (IC50s 0.046, 0.05, 0.321, and 0.24⯵M, respectively). Fusarithioamide B may provide a lead molecule for future developing of antitumor and antimicrobial agents.
