High-Quality Methylxanthines Through Newly Engineered E. Coli Strain

Yielding More Biochemicals Through Greener Processes

THE PROBLEM:

Pharmaceutical treatments of Parkinson's disease, myopia, glaucoma, and macular degeneration are essential for patients' continued quality of life; however, the vital compounds, paraxanthine and 7-methylxanthine, are currently produced using toxic chemicals under environmentally-unfriendly conditions. Due to this added hazard and low yield amounts, both compounds have exceedingly high retail values at approximately $1,400/gram for paraxanthine and $450/gram for 7-methylxanthine, resulting in higher medical costs and financial hardship to patients facing these chronic illnesses.

THE SOLUTION:

Researchers at The University of Alabama have developed a genetically engineered strain of E. coli that produces these essential compounds in larger amounts via a greener, non-toxic biological process, dramatically lowering costs. Using an abundant and inexpensive feedstock like caffeine, this novel synthesis of paraxanthine and 7-methylxanthine can significantly impact the pharmaceutical and cosmetic industries.
