A novel, cost-effective linker creates carboxylic acid end groups on solid supports. This linker, synthesized via polystyrene modification, is acid-labile, enabling efficient peptide synthesis.

Area of Science:

  • Organic Chemistry
  • Solid-Phase Synthesis
  • Biochemistry

Background:

  • Multipin supports are crucial for combinatorial chemistry.
  • Generating carboxylic acid end groups is essential for peptide synthesis.
  • Existing linkers may lack cost-effectiveness or efficiency.

Purpose of the Study:

  • To develop a new, cost-effective linker for carboxylic acid end group generation on Multipin supports.
  • To demonstrate the linker's utility in solid-phase peptide synthesis.

Main Methods:

  • Modification of grafted polystyrene (PS) crowns.
  • Introduction of an acid-labile hydroxyethyl moiety.
  • Synthesis of model decapeptides using the developed linker.

Main Results:

  • A novel linker was successfully synthesized and characterized.
  • The linker demonstrated acid lability in trifluoroacetic acid (TFA)/dichloromethane (DCM).
  • Efficient synthesis of model decapeptides was achieved using the linker.

Conclusions:

  • The developed linker offers a cost-effective and efficient method for generating carboxylic acid end groups.
  • This linker is suitable for solid-phase peptide synthesis on Multipin supports.
  • The acid-labile nature of the linker facilitates controlled cleavage.
