Concise synthetic routes to human insulin.

Area of Science:

• Biochemistry
• Organic Chemistry
• Medicinal Chemistry

Background:

• Human insulin is a critical therapeutic protein for diabetes management.
• Current synthesis methods can be complex and time-consuming.
• Efficient and scalable synthesis routes are needed.

Purpose of the Study:

• To develop concise and efficient chemical synthesis routes for human insulin.
• To explore the utility of Trt, Acm, and t-Bu cysteine protection schemes in insulin synthesis.

Main Methods:

• Chemical synthesis of human insulin using resin-bound assembled A and B chains.
• Employed a two- or three-step combination procedure.
• Utilized Trityl (Trt), Acetamidomethyl (Acm), and tert-Butyl (t-Bu) cysteine protection schemes.

Main Results:

• Achieved a 5.4% overall yield of human insulin.
• Synthesis completed within a single work day.
• Demonstrated the effectiveness of the chosen protection schemes.

Conclusions:

• The reported routes offer a concise and efficient method for human insulin chemical synthesis.
• This approach enables rapid production of human insulin within a day.
• The Trt, Acm, and t-Bu protection strategies are viable for efficient insulin synthesis.
