Q: Please describe this drug.
Constraint: The Compound can be represented with the SMILES COc1cc2c(cc1O)CCN[C@]21CS[C@H]2c3c(OC(C)=O)c(C)c4c(c3[C@@H](COC1=O)N1[C@@H]2[C@H]2c3c(cc(C)c(OC)c3O)C[C@@H]([C@@H]1O)N2C)OCO4.
Answer: A complex structure that includes isoquinolines joined by a cyclic ester; it is a DNA-binding agent and guanine N2 alkylator derived from the marine tunicate, Ecteinascidia turbinata. Trabectedin is used for the treatment of advanced soft-tissue SARCOMA, after failure of ANTHRACYCLINES or IFOSFAMIDE drug therapy.
