Reversed-phase high-performance liquid chromatography of dinucleoside polyphosphates

Area of Science:

• Analytical Chemistry
• Biochemistry

Background:

• Purine dinucleoside polyphosphates are vital signaling molecules.
• Efficient separation methods are needed to study these compounds.

Purpose of the Study:

• To investigate reversed-phase high-performance liquid chromatography (RP-HPLC) for separating purine dinucleoside polyphosphates.
• To develop an isocratic assay for diguanosine and diadenosine polyphosphates.

Main Methods:

• Utilized octadecyl- and phenyl-bonded silica stationary phases.
• Employed phosphate-based eluents with varying pH, ionic strength, and organic modifiers (methanol, acetonitrile).

Main Results:

• Optimized chromatographic conditions for retention and separation.
• Identified key mobile phase parameters influencing separation.
• Established an effective isocratic assay for target compounds.

Conclusions:

• RP-HPLC provides a robust method for purine dinucleoside polyphosphate analysis.
• The developed assay enables reliable quantification of diguanosine and diadenosine polyphosphates.
