Organic CO Prodrugs: Structure-CO-Release Rate Relationship Studies

Area of Science:

• Biochemistry
• Medicinal Chemistry
• Pharmacology

Background:

• Carbon monoxide (CO) acts as an endogenous gasotransmitter in mammals with potential signaling roles in bacteria.
• CO exhibits recognized therapeutic effects, making it a target for medical applications.
• A major obstacle is creating pharmaceutical CO delivery systems with controllable release rates.

Purpose of the Study:

• To describe the first class of organic carbon monoxide (CO) prodrugs.
• To investigate the relationship between the structure of these prodrugs and their CO release rates.
• To enable tunable and controllable CO release in aqueous solutions at neutral pH.

Main Methods:

• Synthesis of a novel class of organic CO-releasing molecules (CORMs).
• Characterization of the prodrug structures.
• Quantitative analysis of CO release kinetics in aqueous buffer at neutral pH.

Main Results:

• The study presents the first organic CO prodrugs capable of releasing CO in neutral aqueous solutions.
• Structure-release rate studies established a correlation between molecular structure and CO release kinetics.
• The developed prodrugs demonstrate tunable release profiles.

Conclusions:

• The described organic CO prodrugs represent a significant advancement in developing controllable CO delivery systems.
• These findings pave the way for pharmaceutically acceptable CO therapeutics with predictable release.
• Further research can explore the therapeutic applications of these novel CO prodrugs.
