Description
|
Trabectedin, also referred as ET-743 during its development, is a marine derived antitumoral agent discovered in the Carribean tunicate _Ecteinascidia turbinata_ and now produced synthetically. Trabectedin has a unique mechanism of action. It binds to the minor groove of DNA interfering with cell division and genetic transcription processes and DNA repair machinery. It is approved for use in Europe, Russia and South Korea for the treatment of advanced soft tissue sarcoma refractory to or unsuitable to receive anthracycline or ifosfamide chemotherapy.
|
| Indication |
Indicated for treatment of advanced soft tissue sarcoma in patients refractory to or unsuitable to receive anthracycline or ifosfamide chemotherapy in Europe, Russia and South Korea. Approved for orphan drug status by the U.S. FDA for treatment of soft tissue sarcomas and ovarian cancer. Investigated for use/treatment in cancer/tumors (unspecified), gastric cancer, ovarian cancer, pediatric indications, sarcoma, and solid tumors. |
| Pharmacology |
Two of the rings in the drug's structure allows it to covalently bind to the minor groove of DNA. The third ring protrudes from the DNA which lets it interact with nearby nuclear proteins. This has the additive effect of blocking cell division at the G2 phase. |
| Absorption |
Administered intravenously. |
| Half Life |
33-50 hours |
| Protein Binding |
94 to 98% |
