Synchronized Fast SPE and UFLC Methods for the Analyses of Eight Antidiabetic Drugs in Human Plasma
Abstract:
Aim and Objective: The population of diabetic patients is rapidly increasing globally. The treatment of these patients is a complex phenomenon due to the use of the different drugs. The present article reports a synchronized fast SPE-UFLC separation of eight antidiabetic drugs in human
plasma. Inexpensive solid phase extraction (SPE) and ultra fast liquid chromatography (UFLC) methods were presented for monitoring of eight antidiabetic drugs in human plasma. The separated drugs include metformin HCl, vildagliptin, gliclazide, linagliptin, sitagliptin, pioglitazone, glimepiride
and repaglinide plasma sample. Material and Method: The column used was a Sunshell C18 (150 x 4.6 mm, 2.6 μm) with eluent of acetate buffer (0.05% TEA in 0.05 M NH4Ac of pH 7.0 with H 3PO4) - ACN (60 : 40, v/v). The flow rate was 1.0 mL/min with a detection wavelength of 210 nm and
column temp. of 45±1ºC. These drugs were extracted from human plasma using Sep-Pac C18 cartridge. Phosphate buffer (25 mM; pH 7.0) containing these drugs were allowed to pass through cartridge at 0.1 mL/min flow rate. The adsorbed drugs on C18 cartridge were eluted by methanol
at 1.0 mL/min flow rate. Results: The values for the retention, separation and resolution factors were ranged from 0.072 to 9.140, 1.443 to 4.208 and 2.147 to 18.652, correspondingly. The percent recoveries for these drugs in the standard laboratory samples prepared in water ranged from
77 to 88%. These values in plasma samples ranged from 10 to 22%. Conclusion: The validated method was fruitfully adopted to analyze these drugs in human plasma for the clinical monitoring of these drugs.

Abstract:
Background: Azocalix[4] arene derivative based on 2,6-diamino pyridine has been synthesized from diazo-coupling reaction between tetradiazonium salt of calix[4]arene and 2,6-diaminopyridine, and characterized by various spectroscopic methods such as IR, 1HNMR, 13CNMR and Mass spe ... mehr
Abstract:
Background: Cancer-associated metabolites result from cell-wide mechanisms of dysregulation. The field of metabolomics has sought to identify these aberrant metabolites as disease biomarkers, clues to understanding disease mechanisms, or even as therapeutic agents. Objective: Thi ... mehr
Abstract:
Background: Despite a reduction in the global burden of malaria, the disease remains responsible for 214 million cases and 438,000 deaths annually with 88% of the mortality occurring in sub-Saharan Africa. Malaria control largely depends on effective chemotherapy. However, the hi ... mehr
