Dapagliflozin-d5 is intended for use as an internal standard for the quantification of dapagliflozin by GC- or LC-MS. Dapagliflozin is a first generation, selective sodium-glucose linked transporter (SGLT) inhibitor that blocks glucose transport with about 100-fold selectivity for SGLT2 (Ki = 6 nM; EC50 = 1.1 nM) over SGLT1 (Ki = 390 nM).1 After single oral doses ranging from 0.1 to 1.0 mg/kg, dapagliflozin increases urinary glucose excretion in both normal and diabetic rats, improves glucose tolerance in normal rats, and reduces hyperglycemia in Zucker diabetic fatty rats.2 Within two weeks of treating diabetic rats with 0.1 to 1.0 mg/kg dapagliflozin, fasting and fed glucose levels have been shown to be significantly lowered as a result of increased glucose utilization accompanied by reduced glucose production.

First identification of dapagliflozin in human hair: Development of a new liquid chromatography with tandem mass spectrometry method
Drug Test Anal 2023 Feb 15.PMID:36793221DOI:10.1002/dta.3457
Sodium-glucose cotransporter 1 inhibitors are a new class of drugs used for the treatment of type II diabetes. Due to their diuretic capabilities and the glycosuria they induce, these molecules cause effective weight loss that could attract the interest of a wider public than diabetics with all the health consequences knowing the adverse effects of these substances. In order to reveal a past exposure to these substances, hair analysis can be very useful especially in the medicolegal context. There are no data in the literature about gliflozin testing in hair. In this study, a method was developed for the analysis of three molecules belonging to the gliflozin family (dapagliflozin, empagliflozin and canagliflozin) using a liquid chromatography system coupled to tandem mass spectrometry. After decontamination with dichloromethane, gliflozins were extracted from hair following incubation in methanol in the presence of Dapagliflozin-d5. Validation showed acceptable linearity for all compounds between 10 and 10,000 pg/mg, with limit of detection and limit of quantification at 5 and 10 pg/mg, respectively. Repeatability and reproducibility were below 20% at three concentrations for all analytes. The method was subsequently applied to the hair of two diabetic subjects under dapagliflozin treatment. In one of the two cases, the result was negative, while in the second case, the concentration was 12 pg/mg. Due to the absence of data, it is difficult to explain the absence of dapagliflozin in the hair of the first case. Physico-chemical characteristics of dapagliflozin could explain its bad incorporation in hair, making detection difficult even after daily treatment.
