A novel class of endogenous mammalian lipids endowed with antidiabetic and anti-inflammatory properties has been recently discovered. These are fatty acid esters of hydroxy fatty acids (FAHFAs) formed by condensation between a hydroxy fatty acid and a fatty acid. FAHFAs are present in human serum and tissues at low nanomolar concentrations. Therefore, high sensitivity and selectivity profiling analysis of these compounds in clinical samples is demanded. An automated qualitative and quantitative method based on on-line coupling between solid phase extraction and liquid chromatography-tandem mass spectrometry has been here developed for determination of FAHFAs in serum with the required sensitivity and selectivity...

The dichromium(III)-containing heteropoly-16-tungstates [Cr(III)2(B-β-Si(IV)W8O31)2](14-) (1) and [Cr(III)2(B-β-Ge(IV)W8O31)2](14-) (2) were prepared via a one-pot reaction of the composing elements in aqueous, basic medium. Polyanions 1 and 2 represent the first examples of Cr(III)-containing heteropolytungstates comprising the octatungstate unit {XW8O31} (X = Si, Ge). Magnetic studies demonstrated that, in the solid state, the two polyanions exhibit a weak antiferromagnetic interaction between the two Cr(III)centers with J = -3...

Dipeptidyl peptidase-4 (DPP-4) inhibitors are a new class of oral antidiabetic agent for the treatment of type 2 diabetes mellitus. They increase endogenous levels of incretin hormones, which stimulate glucose-dependent insulin secretion, decrease glucagon secretion, and contribute to reducing postprandial hyperglycemia. Although DPP-4 inhibitors have similar benefits, they can be differentiated in terms of their chemical structure, pharmacology, efficacy and safety profiles, and clinical considerations. Gemigliptin (brand name: Zemiglo), developed by LG Life Sciences, is a potent, selective, competitive, and long acting DPP-4 inhibitor...

Adiponectin is the most abundant adipokine and exhibits anti-inflammatory, antiatherogenic and antidiabetic properties. Unlike other adipokines, it inversely correlates with body weight and obesity-linked cardiovascular complications. Diastolic dysfunction is the main mechanism responsible for approximately half of all heart failure cases, the so-called heart failure with preserved ejection fraction (HFpEF), but therapeutic strategies specifically directed towards these patients are still lacking. In the last years, a link between adiponectin and diastolic dysfunction has been suggested...

Pancreatic dysfunction during diabetes is linked to the induction of endoplasmic reticulum (ER) stress on pancreatic beta (β) cells. Our laboratory recently discovered that p21 protects from diabetes by modifying the outcome of ER stress response. In the present study, we explored the antidiabetic activity of ciclopirox (CPX), an iron chelator and recently described activator of p21 expression. The effects of CPX in beta cell survival and function were assessed in cultured islets in vitro as well as in diabetic mice in vivo...

Type 2 diabetes mellitus (T2DM) is a complex endocrine and metabolic disorder and is a major global public health problem with a rapidly increasing prevalence. Although a wide range of pharmacotherapy for glycemic control in T2DM is now available, management of T2DM remains complex and challenging. The kidneys contribute to glucose homeostasis primarily by the glucose reabsorption from the glomerular filtrate. The sodium-glucose co-transporter 2 (SGLT2) inhibitors, a new class of antidiabetes agents that inhibit glucose absorption from the kidney tubule independent of insulin, offer a unique opportunity to improve outcomes for patient with T2DM...

Improving efficacy and lowering resistance to metal-based drugs can be addressed by consideration of the coordination complex speciation and key reactions important to vanadium antidiabetic drugs or platinum anticancer drugs under biological conditions. The methods of analyses vary depending on the specific metal ion chemistry. The vanadium compounds interconvert readily, whereas the reactions of the platinum compounds are much slower and thus much easier to study. However, the vanadium species are readily differentiated due to vanadium complexes differing in color...
