Abstract: Objective To study the chemical composition and biological activity of the cultured sponge Tedania anhelans, and provide a basis for the large-scale breeding and development of medicinal sponges. Methods Comprehensive use of thin layer chromatography, silica gel chromatography, ODS C18 chromatography, Sephadex LH-20 gel column chromatography, semi-preparative HPLC, and other methods to separate the chemical components; MS, NMR, and other methods combined with related literature, the structure of the compound was identified. Results 13 compounds were isolated from the cultured sponge T. anhelans, namely cholesterol (1), 24-methylenecholest-5-en-3-hydroxy-7-one (2), and cholesta-5-ene-3β,7α-diol (3), cholesta-5-ene-3β,7β-diol (4), 3β-hydroxycholesta-5-en-7-one (5), Thymidine (6), desmethylthymidine (7), Cyclo-(proline-valine) (8), Piperazirum (9), (E)-4-(1H-indol-3-yl)but-3-en-2-one (10), 3- Indole methyl acetate (11), 3-indole carboxaldehyde (12), pubinernoid A (13). Conclusion All 13 compounds were isolated from this sponge for the first time. Compound 8 showed an inhibition rate of 60.7% against the HSV-2 virus at a concentration level of 50 μmol·L-1. |
