Abstract In diabetes, increased accumulation of sorbitol has been associated with diabetic complications through polyol pathway. Aldose reductase (AR) is one the key factors involved in reduction glucose to sorbitol, thereby its inhibition important for management complications. present study, a series seven 4-oxo-2-thioxo-1,3-thiazolidin-3-yl acetamide derivatives 3 ( a–g ) were synthesized by...

We report the cloning and sequencing of a 1225-base pair cDNA encoding an abundant protein from mouse vas deferens. An open reading frame of 948 nucleotides encodes a protein of 316 amino acids with a calculated mass of 35,965 Da. A high degree of homology was found between this protein and members of the aldo-keto reductase superfamily, especially aldose reductase from human placenta (82%) and...

The polyol pathway is a two-step metabolic pathway in which glucose is reduced to sorbitol, which is then converted to fructose. It is one of the most attractive candidate mechanisms to explain, at least in part, the cellular toxicity of diabetic hyperglycemia because (i) it becomes active when intracellular glucose concentrations are elevated, (ii) the two enzymes are present in human tissues ...

OBJECTIVE To examine the role of aldo-keto reductases (AKRs) in the cardiovascular metabolism of the precursors of advanced glycation end products (AGEs). RESEARCH DESIGN AND METHODS Steady-state kinetic parameters of AKRs with AGE precursors were determined using recombinant proteins expressed in bacteria. Metabolism of methylglyoxal and AGE accumulation were studied in human umbilical vein ...

The aim of this study was to examine the possible antioxidant and antidiabetic effects of the aqueous extracts of four Flemingia species in Taiwan. A number of methods were employed for this investigation, including ABTS radical monocation scavenging, FRAP (ferric reducing antioxidant power) method, DPPH (1, 1-diphenyl-2-picrylhydrazyl) radical scavenging, total polyphenol content, total flavon...
