Bringing Prebiotic Nucleosides and Nucleotides Down to Earth

Area of Science:

• Prebiotic chemistry
• Systems chemistry
• Origin of life studies

Background:

• Understanding the chemical pathways to RNA is crucial for origin of life research.
• Prebiotic systems chemistry explores how simple molecules could assemble into complex life components.

Purpose of the Study:

• To explore novel synthetic routes for prebiotic nucleoside and nucleotide precursors.
• To investigate the formation of complex molecular structures from simple chemical components relevant to early Earth.

Main Methods:

• Synthesis of nucleoside precursors by mixing Butlerow's carbohydrate precursors with Traube's 5-formylaminopyrimidines.
• Formation of supramolecular fibers using 5-phosphoribose, barbituric acid, and melamine.

Main Results:

• Successful synthesis of prebiotic purine nucleosides.
• Creation of supramolecular fibers from stacked rosettas.

Conclusions:

• Multiple chemical pathways may have led to the formation of RNA precursors.
• These findings contribute to understanding the self-assembly processes in prebiotic systems.
