The present disclosure relates to systems and methods for determining the renal glomerular filtration rate or assessing the renal function in a patient in need thereof. The method includes administering a pyrazine compound of Formula I to a patient and monitoring the rate in which the kidneys of the patient eliminate the pyrazine from the systemic circulation of the patient. The pyrazine compound fluoresces when exposed to electromagnetic radiation which is detected using one or more sensors. The rate in which the fluorescence decreases in the patient is used to calculate the renal glomerular filtration rate in the patient.

The present invention relates to pyrazine derivatives such as those represented by Formulas I and II below.
X
1
to X
4
of the compounds of Formulas I and II may be characterized as electron withdrawing groups. In contrast, Y

to Y
4
of the compounds of Formulas I and II may be characterized as electron donating groups. Pyrazine derivatives of the present invention may be utilized in assessing renal function. In particular, an effective amount of a pyrazine derivative of the invention may be administered into a body of a patient. The pyrazine derivative that is in the body may be exposed to visible and/or infrared light to cause spectral energy to emanate from the pyrazine derivative. This emanating spectral energy may be detected and utilized to determine renal function of the patient.
