Abstract
Background: A chiral HPLC technique was developed to determine sitagliptin phosphate enantiomers in rat plasma in compliance with US FDA regulations. Methods & results: The technique used a Phenomenex column with a mobile phase consisting of a 60:35:5 (v/v/v) blend of pH4, 10-mM ammonium acetate buffer, methanol and 0.1% formic acid in Millipore water. The precision for both (R) and (S) sitagliptin phosphate varied between 0.246 and 1.246%, while the accuracy was 99.6-100.1%. A glucose uptake assay was used to assess enantiomers in 3T3-L1 cell lines through flow cytometry. Conclusion: Investigation of the pharmacokinetic impacts of sitagliptin phosphate racemic enantiomers in rat plasma revealed notable contrasts in R and S enantiomers in female albino Wistar rats, suggesting enantioselectivity for sitagliptin phosphate.

Abstract
Sitagliptin is a dipeptidyl peptidase-IV inhibitor for the treatment of type 2 diabetes mellitus. In the present study, a sensitive and high-throughput quantitative method based on the direct analysis in real time tandem mass spectrometry has been developed and validated for the bioanalysis of sitagliptin in rat plasma without chromatographic separation. Sitagliptin and its internal standard retagliptin were detected in positive ion mode by multiple reaction monitoring transitions at m/z 408.2→235.0 and 465.2→260.1, respectively. The method includes a simple solid-phase extraction sample preparation procedure, through which appropriate and reproducible analytical results within the linear concentration range of 20-2000 ng/mL have been achieved. The intra- and interday precisions were <10.6% and the accuracies were ranging from -8.17 to 2.60%. This method has been successfully applied to the pharmacokinetic study of sitagliptin after single intravenous administration in rats. This approach shows considerable promise of direct analysis in real time tandem mass spectrometry method in the high-throughput bioanalysis.

Abstract
Sitagliptin is a hypoglycaemic agent used to reduce blood sugar levels in patients with type 2 diabetes mellitus (T2DM). Real time monitoring of sitagliptin levels is crucial to prevent overdose, which might cause liver, kidney and pancreatic diseases. As an alternative solution, a sitagliptin voltammetric sensor was fabricated using artificial receptors called electroactive molecularly imprinted polymer nanoparticles (nanoMIPs). The nanoMIP tagged with a redox probe (ferrocene) combines both the recognition and reporting functions. Traditional electrochemical sensors determine the redox activity of an analyte. Thus, they are influenced by interfering molecules and the nature of the sample. These innovative nanoMIPs allow us to easily design and customise sensors, increase their sensitivity and minimise the cross reactivity in biological samples. The present technology replaces the traditional enzyme-mediator pairs used in traditional biosensors. The polymer composition was optimized "in silico" using docking and screening methods. Nanoparticles were synthesized via free radical polymerization and a solid phase method and then characterized by infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and dynamic light scattering (DLS). The specific sitagliptin nanoparticles were covalently immobilized on platinum electrodes via silane and carbodiimide chemistry. The determination of sitagliptin in human plasma by a nanoMIP sensor was assessed by differential pulse voltammetry (DPV). The sensor current response was directly related to the change in nanoMIP conformation triggered by the analyte. The optimisation of the sensor response was made by adjusting (i) the silane concentration, (ii) nanoMIP concentration, and (iii) immobilization time. The sensor measurements in plasma revealed high selectivity and a sensitivity of 32.5 ± 0.6 nA pM-1 towards sitagliptin, and the limit of detection of the fabricated sensor was found to be 0.06 pM. The sensor displayed a satisfactory performance for the determination of sitagliptin in spiked human plasma, demonstrating the potential of this technology for drug monitoring and clinical diagnosis.

Abstract
Background:
The determination of trace drugs in aquatic environments is important. For
this purpose, many methods such as High Performance Liquid Chromatography (HPLC) and gas
chromatography mass spectrometry (GC/MS) have been used.
Objective:
This study introduces a simple, sensitive, and rapid colorimetric method for the spectrophotometric
determination of sitagliptin (STG) in drinking water, tablet, human plasma, and human
urine using gold nanoparticles (AuNPs).
Methods:
The Surface Plasmon Resonance (SPR) property of AuNPs and the interaction between
STG and AuNPs are the base of the colorimetric method. The addition of STG into AuNPs led to the
aggregation of AuNPs. Transmission Electron Microscopy (TEM) proved the aggregation of AuNPs
in the presence of STG. Also, the size of the nanoparticles distribution was evaluated by Dynamic
Light Scattering (DLS). In addition, Fourier-Transform Infrared Spectrophotometer (FTIR) was used
to study the chemical structure of AuNPs, STG, and AuNPs in the presence of STG.
Results:
The parameters that affect the absorbance such as pH, type and volume of buffer, AuNPs
concentration, interaction time, ionic strength, and interfering ions were investigated and optimized.
Under the optimum conditions, the determination of STG was performed via this method over the
range of 50-300 μgL-1 (R2=0.9941) with the Limit of Detection (LOD) and Limit of Quantification
(LOQ) of 1.23 and 1.39 μgL-1, respectively.
Conclusion:
Eventually, the results showed that the proposed method has a high potential for simple,
rapid, sensitive, and accurate determination of STG.

Abstract
Dipeptidyl peptidase 4 (DPP-4) inhibitors are incretin-based medications used as oral antidiabetic agents for the treatment of type 2 diabetes. However, DPP-4 inhibitors produce side effects like acute pancreatitis, upper respiratory tract infection, nasopharyngitis, urinary tract infection, serious allergies, cardiovascular diseases, hemolysis, and retinopathy. Hence, the development of a fast and simple method to detect DPP-4 inhibitors in body fluids is important. In this study, we developed a derivatization-assisted microextraction method to enhance the detection sensitivity for trace levels of a DPP-4 inhibitor, sitagliptin, from a small volume (10 μL) of human plasma by using matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). Subjecting the analyte to 100 W microwave irradiation after derivatization using a quinoline alkylating reagent (8-bromomethyl quinilone, BrMQ) shortened the reaction time to ~120 s and allowed the target analyte to be easily extracted to a small volume of the organic layer (20 μL). The analyte was then detected by MALDI-TOF MS using α-cyano-4-hydroxycinnamic acid as the matrix. The relative standard deviation and relative error were below 10% in intra- and inter-day assays. Using sitagliptin-d4 as an internal standard, the limits of quantitation and detection were found to be 0.03 μg/mL and 0.01 μg/mL, respectively. All the derivatization and extraction procedures described herein were of microliter grade. This method could effectively reduce the use of organic chemicals and solvents, thereby proving to be an eco-friendly strategy that will cause no harm to the environment.

Abstract
This article describes the development and validation of a HILIC-MS/MS method for the simultaneous quantification of metformin and sitagliptin from human plasma and urine. The presented method uses quick sample preparation and fast chromatography allowing for high sample throughput. The quantification is performed using multi-reaction monitoring and ESI positive mode with stable isotope labelled internal standards for both metformin and sitagliptin. Excellent linearity in the selected calibrations ranges, low inter-day variability (CV% <6.7%), and high accuracy (95.5-104.1%) were obtained. Adequate retention was attained for both analytes by hydrophilic interaction liquid chromatography using a plain silica column in combination with a mobile phase composed of ammonium formate, acetonitrile, formic acid and water in gradient separation mode.

Abstract
A reversed-phase liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) method was established for simultaneous determination of two oral hypoglycemic drugs metformin (MET) and sitagliptin (STG) in human plasma. The analytes were extracted from 50μL human plasma by ion-pair solid phase extraction using sodium lauryl sulphate on Phenomenex Strata-X (30mg/1mL) cartridges. The chromatographic separation was accomplished on XSelect HSS CN (150×4.6mm, 5μm) column using mobile phase consisting of methanol-8.0mM ammonium formate in water, pH 4.5 (80:20, v/v) under isocratic condition. Tandem MS detection was performed on a triple quadrupole spectrometer equipped with an electrospray ionization source, operated in the positive mode. Multiple reaction monitoring (MRM) was used to quantify the analytes following transitions, m/z 130.1→60.1 and m/z 408.3→235.1 for MET and STG respectively. The method displayed acceptable linearity in the concentration range of 4.00-3200ng/mL for MET and 1.00-800ng/mL for STG. The intra-batch and inter-batch precisions were ≤5.1% and accuracy ranged from 96.5 to 103.3% for both the drugs. The mean recovery of MET and STG obtained from spiked plasma samples was 82.5% and 90.4% respectively with minimal matrix interference. Both the drugs were found to be stable under all mandatory storage conditions. The validated method was successfully applied to a clinical pharmacokinetic study for a fixed-dose tablet formulation containing 500mg MET and 50mg STG in 16 healthy volunteers.

Abstract
A sensitive and selective gas chromatography-mass spectrometry (GC-MS) method was developed and fully validated for the determination of vildagliptin (VIL) in pharmaceutical formulation. Prior to GC-MS analysis, VIL was efficiently derivatized with MSTFA/NH4I/β-mercaptoethanol at 60°C for 30 min. The obtained O-TMS derivative of VIL was detected by selected ion monitoring mode using the diagnostic ions m/z 223 and 252. Nandrolone was chosen as internal standard. The GC-MS method was fully validated by the following validation parameters: limit of detection (LOD) and quantitation (LOQ), linearity, precision, accuracy, specificity, stability, robustness, and ruggedness. LOD and LOQ were found to be 1.5 and 3.5 ng mL(-1), respectively. The GC-MS method is linear in the range of 3.5-300 ng mL(-1). The intra- and interday precision values were less than ≤3.62%. The intra- and interday accuracy values were found in the range of -0.26-2.06%. Finally, the GC-MS method was successfully applied to determine VIL in pharmaceutical formulation.

Abstract
Three extraction methods were compared for their efficiency to analyze sitagliptin and simvastatin in rat plasma by LC–MS/MS, including (1) liquid–liquid extraction (LLE), (2) solid phase extraction (SPE) and (3) supported liquid extraction (SLE). Comparison of recoveries of analytes with different extraction methods revealed that SLE was the best extraction method. The detection was facilitated with ion trap-mass spectrometer by multiple reactions monitoring (MRM) in a positive ion mode with ESI. The transitions monitored were m/z 441.1→325.2 for simvastatin, 408.2→235.1 for sitagliptin and 278.1→260.1 for the IS. The lower limit of quantification (LLOQ) was 0.2 ng/mL for sitagliptin and 0.1 ng/mL for simvastatin. The effective SLE offers enhanced chromatographic selectivity, thus facilitating the potential utility of the method for routine analysis of biological samples along with pharmacokinetic studies.
