Description

Trabectedin is an alkylating drug with the chemical name (1′R,6R,6aR,7R,13S,14S,16R)-5-(acetyloxy)-3′,4′,6,6a,7,13,14,16-octahydro-6′,8,14-trihydroxy-7′,9-dimethoxy-4,10,23-trimethyl-spiro[6,16-(epithiopropanoxymethano)-7,13-imino-12H-1,3-dioxolo[7,8]isoquino[3,2-b][3]benzazocine-20,1′(2′H)-isoquinolin]-19-one. The molecular formula is C39H43N3O11S. The molecular weight is 761.84 daltons. The chemical structure is shown below:

Trabectedin is hydrophobic and has a low solubility in water.

YONDELIS (trabectedin) for injection is supplied as a sterile lyophilized white to off-white powder/cake in a single-dose vial. Each single-dose vial contains 1 mg of trabectedin, 27.2 mg potassium dihydrogen phosphate, 400 mg sucrose, and phosphoric acid and potassium hydroxide (for pH adjustment to 3.6 – 4.2).

Mechanism of Action

Trabectedin is an alkylating drug that binds guanine residues in the minor groove of DNA, forming adducts and resulting in a bending of the DNA helix towards the major groove. Adduct formation triggers a cascade of events that can affect the subsequent activity of DNA binding proteins, including some transcription factors, and DNA repair pathways, resulting in perturbation of the cell cycle and eventual cell death.
