Task: Please give me a SMILES based on the text description below.
Description: The molecule is a peptide cation obtained by deprotonation of the carboxy terminus and protonation of the side-chain guanidino group and the amino terminus of Phe-Arg; major species at pH 7.3. It is a conjugate acid of a Phe-Arg.
Result: NC(N)=[NH+]CCC[C@H](NC(=O)[C@@H]([NH3+])Cc1ccccc1)C(=O)[O-]
