Role of Peptide Synthesis Based Drugs

JANUARY 04, 2021

Role of Peptide Synthesis Based Drugs

Amino acids, peptides and proteins play multiple roles in the normal functioning of the body.Group of amino acids between 2 to 50 are called peptides. They often act as hormones and play diverse roles in the normal biological processes in the human body such as metabolism, intercellular signaling and neurotransmission.Peptide synthesis based drug have a high pote...

Alternate end-game strategies towards Nirmatrelvir synthesis: Defining a continuous flow process for the preparation of an anti-COVID drug


Scalable alternate end-game strategies for the synthesis of the anti-COVID drug molecule Nirmatrelvir (1,PF-07321332) have been described. The first involves a direct synthesis of 1 via amidation of the carboxylic acid 7 (suitably activated as a mixed anhydride with either pivaloyl chloride or T3P) with the ...

Frequently asked questions

What are the methods for peptide synthesis?

There are three major synthesis routes for peptides, solid phase peptide synthesis (SPPS), solution/liquid phase peptide synthesis (LPPS) and hybrid phase peptide synthesis. Hybrid phase peptide synthesis is a combination of solid and liquid peptide synthesis methods.

What is the use of microwave in peptide synthesis?

Microwave assisted peptide synthesis is one of the most efficient and environmentally friendly method, it enables high throughput synthesis of difficult to make peptides and reduces cycle times to 4 minutes while minimizing the required amount of solvent by 90%.

How long does peptide synthesis take?

Peptide synthesis depends on the required sequence length, complexity, purity and quantity of the peptide, it usually ranges from few days for a peptide to few weeks depending on these variables.

What methods are used by Aurigene to manufacture peptides?

Aurigene has expertise in development and manufacturing of peptides via solid phase peptide synthesis (SPPS) and liquid phase peptide synthesis (LPPS) procedures.

The strategies involved are

  • Convergent solid phase peptide synthesis where to fragments can be made separately and couple to make the final peptide
  • Hybrid phase peptide synthesis which involves the combination of SPPS & LPPS methods. Our laboratories are equipped with manual and automated (CS Bio) peptide synthesizers to support the peptide synthesis as per the requirement.

What is the typical maximum length of a synthesized peptide?

Depending on the requirements, short and longer peptides can be synthesized between 5mer-50mer. SPPS approach is preferable to generate longer peptides Ex: 50 mer (with 50 amino acids).

Which is the best method for synthesizing of a long chain peptide?

Long chain peptides can be preferably synthesized following Solid Phase Peptide Synthesis (SPPS) procedures. Depending on the length and complexity of the peptide convergent or hybrid approaches can be adopted.
