    Structural Characterization<\/h3>\n

    PT-141 is a compact macrocyclic peptide whose constrained geometry is defined by a lactam linkage between the aspartyl and lysyl residues. The sequence contains norleucine, aromatic residues, and basic side chains, giving the compound a mixed hydrophobic and cationic profile in laboratory characterization.<\/p>\n
