Product Name:
Trabectedin
CAS Number:
114899-77-3
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.
Mode of Action:

Trabectedin interacts with the minor groove of DNA and alkylates guanine at the N2 position, which bends towards the major groove. In this manner, it is thought that the drug affects various transcription factors involved in cell proliferation, particularly via the transcription-coupled nucleotide excision repair system. Trabectedin blocks the cell cycle at the G2 phase, while cells at the G1 phase are most sensitive to the drug. It also inhibits overexpression of the multidrug resistance-1 gene (MDR-1) coding for the P-glycoprotein that is a major factor responsible for cells developing resistance to cancer drugs. The agent is also thought to interfere with the nucleotide excision repair pathways of cancer cells, suggesting that it could be effective in the treatment of many cancer types including melanoma and sarcoma, as well as lung, breast, ovarian, endometrial and prostate cancers; clinical evaluations are underway in these indications.

Pharmacodynamics:

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.
