ECDG
ECDG is a small-molecule compound dependent on α-ketoglutarate/Fe2+ that participates in the biosynthesis of echinocandins. ECDG is involved in the targeted transport of glucose, and can be used for PET imaging after labeling with radioactive atoms. ECDG increases blood glucose levels in rats, undergoes cellular uptake mediated by D-glucose, localizes in ischemic viable myocardial tissue, and accumulates in the synovial space of rheumatoid arthritis. ECDG can be used in research related to candidiasis, glucose metabolism disorders, fungal infections, myocardial ischemia and rheumatoid arthritis.

Animal Model:Fischer 344 (female, 145-155 g, healthy; female, 250-275 g, inoculated subcutaneously with 13762 mammary tumor cells)[2]
-
Dosage:1.2 mM/kg
-
Administration:i.v. (ECDG, 99mTc ECDG, unlabeled FDG); i.m. (insulin); single dose
-
Result:Increased blood glucose levels in healthy rats, which dropped to ~20 mg/dL by 180 minutes post-insulin injection.
Recorded mean tumor-to-nontumor ROI ratios of 1.70 (immediate), 1.58 (30 minutes), and 1.82 (2 hours) for 3 mm tumors, and 2.36 (immediate), 2.41 (30 minutes), and 2.88 (2 hours) for 6 mm tumors.
Reduced tumor uptake of 99mTc ECDG by 40% following unlabeled FDG pretreatment.
Increased tumor uptake of 99mTc ECDG by 60% following insulin pretreatment.
Enabled better breast tumor visualization than 99mTc ethylenedicysteine at equivalent time points.
