Abstract
Diabetic people have a much higher rate of cardiovascular disease than healthy people. Therefore, heart and aortic tissues are target tissues in diabetic research. In recent years, the synthesis of new vanadium complexes and investigation of their antidiabetic/lowering effect on the blood glucose levels and antioxidant properties are increasing day by day. Our study aimed to examine the effects of synthesized oxovanadium (IV) complex of 2-[(2,4-dihydroxybenzylidene]hydrazine-1-[(N-(2-hydroxybenzylidene)](S-methyl)carbothioamide [VOL] on diabetic heart and aortic tissues, as well as in vitro lactate dehydrogenase (LDH) and myeloperoxidase (MPO) inhibition, antioxidant properties, and reducing power. Electrochemical characterization of the VOL was carried out by using Cyclic Voltammetry (CV) and Linear Sweep Voltammetry (LSV) methods. In addition, in silico drug-likeness and ADME prediction were also investigated. For in vivo study, male Swiss albino rats were randomly selected and separated into four groups which are control, control + VOL, diabetic and diabetic + VOL. After the experimental procedure, biochemical parameters were investigated in homogenates of heart and aorta tissues. The results showed that VOL has a protective effect on heart and aortic tissue against oxidative stress. According to electrochemical experiments, one reversible oxidative couple and one irreversible reductive response were observed for the complex. In addition, in vitro LDH and MPO inhibition of VOL was examined. It was found that VOL had a protective effect on heart and aortic tissues of diabetic rats, and caused the inhibition of LDH and MPO in in vitro studies. On the other hand, evaluating the synthesized VOL according to in silico drug-likeness and absorption, distribution, metabolism, and excretion (ADME) prediction, it was found that VOL has drug-like properties and exhibited high gastrointestinal absorption. The VOL had a therapeutic impact on the heart and aortic tissues of diabetic rats, according to the findings.

Possibility of Venous Serum Cl - Concentration ([Cl -] s) as a Marker for Human Metabolic Status: Correlation of [Cl -] s to Age, Fasting Blood Sugar (FBS), and Glycated Hemoglobin (HbA1c). Int J Mol Sci 2021; 22:ijms222011111. [PMID: 34681771 PMCID: PMC8537275 DOI: 10.3390/ijms222011111] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Revised: 10/09/2021] [Accepted: 10/12/2021] [Indexed: 11/17/2022] Open
Abstract
The HCO3− concentration in venous serum ([HCO3−]s) is a factor commonly used for detecting the body pH and metabolic conditions. To exactly detect [HCO3−]s, the venous CO2 pressure should be kept as it is in the vein. The [HCO3−]s measurement is technically complicated to apply for huge numbers of almost heathy persons taking only basic medical examinations. The summation of [HCO3−]s and the venous serum Cl− concentration ([Cl−]s) is approximately constant; therefore, we studied if [Cl−]s could be a marker detecting metabolic conditions instead of [HCO3−]s. Venous blood was obtained from persons taking basic medical examinations (the number of persons = 107,630). Older persons showed higher values of [Cl−]s, fasting blood sugar (FBS), and glycated hemoglobin (HbA1c) than younger ones. [Cl−]s showed positive correlation to age and negative correlation to FBS and HBA1c. The negative correlation of [Cl−]s to FBS/HbA1c was obvious in persons with high FBS/HbA1c, leading us to an idea that persons with high FBS/HbA1c show high [HCO3−]s, which might be caused by low activity of carbonic anhydrase in the lung observed in persons with diabetes mellitus under acidotic conditions. Taken together, an easily measured serum electrolyte, [Cl−]s, could be a useful marker estimating metabolic conditions.
