Chemical Synthesis of Cell Wall Constituents of Mycobacterium tuberculosis

Area of Science:

• Organic chemistry
• Immunology
• Microbiology

Background:

• Mycobacterium tuberculosis (Mtb) has a unique, thick cell envelope rich in lipids, glycolipids, and glycans.
• These cell wall components are crucial for Mtb's interaction with hosts, survival, and virulence.
• Mycobacterial natural products are of significant interest due to their complex structures and biological roles.

Purpose of the Study:

• To review 25 years of total synthesis efforts on Mtb cell envelope components.
• To highlight how synthetic chemistry has enabled immunological studies of Mtb.
