User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a tripeptide composed of N-acetylleucyl, leucyl and argininal residues joined in sequence. It has a role as a serine protease inhibitor, a bacterial metabolite, a cathepsin B inhibitor, a calpain inhibitor and an EC 3.4.21.4 (trypsin) inhibitor. It is a tripeptide and an aldehyde.
Assistant: This is a molecule that fits this description: CC(=O)N[C@@H](CC(C)C)C(=O)N[C@@H](CC(C)C)C(=O)N[C@H](C=O)CCCN=C(N)N
