Regioselective semi-synthesis of 6-isomers of 5,8-O-dimethyl ether of shikonin derivatives via an ‘intramolecular ring-closing/ ring-opening’ strategy as potent anticancer agents

Regioselective semi-synthesis of 6-isomers of 5,8-O-dimethyl ether of shikonin derivatives via an ‘intramolecular ring-closing/ ring-opening’ strategy as potent anticancer agents

Synthesis of 6-isomer of 5,8-O-dimethyl ether of shikonin (13), a promising anticancer scaffold, always remains a huge challenge. Herein a key intermediate for 13, 2-(1-hydroxyl-4-methyl-3-pentenyl)-1,4,5,8-tetramethoxynaphthalene (10), was obtained on the large-scale synthesis

Decreased expression of hyaluronan synthase 1 and 2 associates with poor prognosis in cutaneous melanoma

Hyaluronan metabolism in cutaneous melanoma seems to differ from the main adenocarcinomas, such as the breast carcinoma. Increased stromal hyaluronan content has been associated with poor survival and tumor differ- entiation in various human adenocarcinomas, whereas re- duced levels of hyaluronan ar[r]
