Structural Characterization

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.

  • Peptide Class: Cyclic heptapeptide with C-terminal free acid
  • Conformation: Lactam-constrained macrocycle
  • UV Absorption: Aromatic residue signal from Trp and Phe chromophores
  • Appearance: White to off-white lyophilized powder

Physicochemical Notes

  • Solubility: Soluble in aqueous laboratory buffers
  • Charge Profile: Mixed cationic and hydrophobic residue distribution
  • Handling: Best stored frozen, dry, and protected from prolonged light exposure
