User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a member of the class of bilenes that is 1,2,3,21-tetrahydro-5,7-ethanobilene-a-19(16H),5(2)-dione which is substituted at positions 2, 8, 13 and 18 by methyl groups and at positions 1, 3, 12 and 17 by carboxy, 2-carboxyethyl, ethyl and vinyl groups, respectively (the 1S,2S,3S diastereoisomer). It has a role as a luciferin. It is a member of bilenes, an oxo dicarboxylic acid, an amino dicarboxylic acid and a non-proteinogenic L-alpha-amino acid. It is a conjugate acid of a dinoflagellate luciferin(1-).
Assistant: This is a molecule that fits this description: C=CC1=C(C)C(=O)NC1Cc1[nH]c(Cc2[nH]c3c(c2C)C(=O)C/C3=C2/N[C@H](C(=O)O)[C@@H](C)[C@@H]2CCC(=O)O)c(CC)c1C
