Fluorogenic gemcitabine based light up sensor for serum albumin detection in complex biological matrices.

Area of Science:

• Chemical Synthesis
• Biochemistry
• Medical Diagnostics

Background:

• Albumin is a key biomarker for various health conditions.
• Existing methods for albumin detection can be complex or lack sensitivity.
• Development of novel, sensitive diagnostic tools is crucial for early disease detection.

Purpose of the Study:

• To synthesize a novel fluorogenic derivative of gemcitabine (GEM-DNS).
• To evaluate GEM-DNS as a sensitive and selective probe for albumin quantification.
• To explore the utility of GEM-DNS in complex biological media for disease diagnostics.

Main Methods:

• Single-step synthesis of GEM-DNS from gemcitabine hydrochloride and dansyl chloride.
• Characterization of GEM-DNS's photophysical properties, including a large stoke shift (~200 nm).
• Application of GEM-DNS for albumin concentration estimation in human urine and blood serum.

Main Results:

• Successful synthesis of GEM-DNS with desirable photophysical properties.
• Demonstrated high sensitivity and selectivity of GEM-DNS towards albumin.
• Effective quantification of albumin in complex biological samples like urine and serum.

Conclusions:

• GEM-DNS is a potent fluorogenic probe for albumin detection.
• The dye serves as a valuable diagnostic tool for conditions associated with altered albumin levels.
• GEM-DNS facilitates early detection of liver cirrhosis, diabetes, and hypertension.
