User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an S-substituted N-acetyl-L-cysteine arising from formal 1,4-addition of the side-chain sulfur atom to N-ethylmaleimide. It is a S-substituted N-acetyl-L-cysteine and an organic sulfide. It derives from a N-ethylsuccinimide.
Assistant: This is a molecule that fits this description: CCN1C(=O)CC(SC[C@H](NC(C)=O)C(=O)O)C1=O
