Use | Tribetitin is an alkylating agent suitable for patients with unresectable or metastatic liposarcoma or leiomyosarcoma receiving a previous anthracycline [anthracycline]-regimen. |
a new drug for the treatment of soft tissue sarcoma-trabetidine | On October 23, 2015, FDA approved the listing of trabetidinol (Trabectedin), a drug of Janssen (Janssen) Company, a subsidiary of Johnson & Johnson, under the trade name Yondelis. For the treatment of patients with non-resectable or metastatic liposarcoma and leiomyosarcoma who have received chemotherapy containing an anthracycline. Tribetete was designated as an alkylating agent as a cytotoxic drug. In 2007, EMEA approved it to be listed for the first time in Europe for the treatment of advanced soft tissue sarcoma. Later, it was approved to treat recurrent ovarian cancer in Europe and Canada. The manufacturers are Spanish biotechnology company Zeltia and Johnson and Johnson. |
biological activity | Trabectedin (Ecteinascidin 743; ET-743) is a tetrahydroisoquinoline alkaloid with effective anti-tumor activity and is isolated from Ecteinascidia turbinata. Trabectedin bind to small grooves of DNA, block stress-induced protein transcription, induce DNA skeleton lysis and cancer cell apoptosis (apoptosis), and increase ROS production in MCF-7 and MDA-MB-453 cells. Trabectedin can be used for the study of soft tissue sarcoma and ovarian cancer. |

Trabectedin (ET-743; 10 nM; 24-72 hours; MCF7 cells) treatment cells accumulate in late S to G2 phase.
Trabectedin (Ecteinascidin 743) inhibits cell growth of MX-1, MCF7 and MCF7/DXR cells with IC 50 values of 0.1 nM, 1.5 nM and 3.7 nM, respectively.
Trabectedin induces cytotoxicity and apoptosis in both breast cancer cells in a time and concentration-dependent manner. The expression levels of the death receptor pathway molecules, TRAIL-R1/DR4, TRAIL-R2/DR5, FAS/TNFRSF6, TNF RI/TNFRSF1A, and FADD are significantly increased by 2.6-, 3.1-, 1.7-, 11.2- and 4.0-fold by Trabectedin treatment in MCF-7 cells. In MDA-MB-453 cells, the mitochondrial pathway related pro-apoptotic proteins Bax, Bad, Cytochrome c, Smac/DIABLO, and Cleaved Caspase-3 expressions are induced by 4.2-, 3.6-, 4.8-, 4.5-, and 4.4-fold, and the expression levels of anti-apoptotic proteins Bcl-2 and Bcl-XL are reduced by 4.8- and 5.2-fold in MDA-MB-453 cells.
In vitro treatment with noncytotoxic concentrations of Trabectedin selectively inhibits the production of CCL2, CXCL8, IL-6, VEGF, and PTX3 by myxoid liposarcoma (MLS) primary tumor cultures and/or cell lines.

Trabectedin (ET-743; 30-50 μg/kg; intravenous injection; every three days; female athymic nude mice) treatment increases the antitumor effects in nude mice bearing MX-1 mammary carcinoma xenografts without increasing toxicity.
A xenograft mouse model of human myxoid liposarcoma (MLS) shows marked reduction of CCL2, CXCL8, CD68 infiltrating macrophages, CD31 tumor vessels, and partial decrease of PTX3 after Trabectedin treatment.
Animal Model: | Female athymic nude mice bearing the nu/nu gene (5-6 weeks old, 18-20 g) injected with MX-1 cells |
Dosage: | 30 μg/kg, 40 μg/kg, 50 μg/kg |
Administration: | Intravenous injection; every three days |
Result: | Increased the antitumor effects in nude mice bearing MX-1 mammary carcinoma xenografts without increasing toxicity. |
