| Quinone-methide triterpenes and salaspermic acid from Kokoona ochracea.[Pubmed: 8158155] |
METHODS AND RESULTS:
Tingenone[1],20-hydroxy-20-epi-tingenone[2],celastrol[ 3], and Salaspermic acid [4] have been isolated from Kokoona ochracea stem bark. The quinone-methide triterpenes 1-3 exhibited strong but non-specific in vitro cytotoxicity against P-388 murine lymphocytic leukemia cells and a panel of human cancer cell lines. Salaspermic acid [4] was not active in all the cancer cell lines used in this investigation.
CONCLUSIONS:
13C-nmr spectra assignments for Salaspermic acid have been accomplished through the application of 1D and 2D nmr spectral techniques, and 13C-nmr assignments for celastrol [3] have been revised. |

| Anti-aids agents, 6. Salaspermic acid, an anti-HIV principle from Tripterygium wilfordii, and the structure-activity correlation with its related compounds.[Pubmed: 1375626] |
METHODS AND RESULTS:
Salaspermic acid [1], an inhibitor of HIV reverse transcriptase and HIV replication in H9 lymphocyte cells, was isolated from the roots of Tripterygium wilfordii for the first time. The structure of 1 derived from spectral data was established unequivocally by an X-ray analysis of crystals of the monohydrate.
CONCLUSIONS:
A structure-activity correlation of 1 with ten related compounds indicated that the acetal linkage in ring A and the carboxyl group in ring E of 1 may be required for the anti-HIV activity. |
