Testusterol, a new sterol of the sponge species Xestospongia testudinaria from Phu Quoc island, Vietnam
A new sterol, named testusterol (1), and five known compounds (2-6) were isolated from the n-hexane and dichloromethane extracts of the sponge species Xestospongia testudinaria. Their chemical structures were elucidated based on extensive spectroscopic analyses (1D, 2D NMR, ESIMS and HRESIMS) and comparison with published data. The results of in vitro test (utilizing brine shrimp Artemia salina LEACH) showed that three extracts ethanol, dichloromethane, and ethanol/water, significantly inhibited Artemia salina with LC50 values ranging from 6.09 to 16.83 µg/mL. Remarkably, the new compound 1 exhibited potent inhibition against both Gram-positive (Staphyloccocus aureus, Bacillus subtilis, Lactobacillus fermentum), and Gram-negative (Escherichia coli, Salmonella enterica, Pseudomonas aeruginosa) bacteria species, with IC50 values of less than 12.0 nM and MIC ranging from 4.70 to 75.23 nM as determined by the broth-microdilution assay.
