Description
Technical Field
The disclosure belongs to the field of medicines, and relates to a preparation method of ecteinascidin compounds.
Background
Tribetidine (trade name Yondelis), developed by Qiangsheng pharmaceutical Co., Ltd., is a natural product isolated from the marine organism Ecteinascidia turbinata, but its content is extremely low, only 10 -6 ~10 -7 % w/w. Tributine was listed as a rare drug for soft tissue sarcoma in the European Union in 2001, and became the first modern marine drug. In 2004, the drug was classified by the U.S. Food and Drug Administration (FDA) as a rare drug for soft tissue sarcoma, and in europe and america, it was designated as an orphan drug for the treatment of acute lymphoblastic leukemia, soft tissue sarcoma, and ovarian cancer. Tribetidine can block tumorIn addition to the differentiation of cells in the G1/G2 cycle, the cells can also inhibit the secretion of Vascular Endothelial Growth Factor (VEGF) and the expression of its receptors. EP0309477B discloses a class of ecteinascidin compounds including ecteinascidins 729, 743 (trabectedin), 745, 759A, 759B and 770.
