Background: Several metabolic pathways are involved in the complications of diabetes like polyol pathway. Aldose reductase (AR) is a key enzyme in the polyol pathway, which catalyzes the conversion of glucose to sorbitol. AR inhibitors are appropriate to prevent and treat the diabetes complications. Objective: This study was designed to investigate the effect of different fractions of Teucrium ...

Enzymes can generally use either NADPH or NADH, but not both. Reactions requiring the input of electrons as hydride ions are usually catalyzed by enzymes specific for NADPH. Fig. 29.1. Fructose. The sugar fructose is found in the diet as the free sugar in foods such as honey or as a component of the disaccharide sucrose in fruits and sweets. It also can be synthesized from glucose via the polyo...

Butyrolactol A is an antifungal polyketide of Streptomyces bearing an uncommon tert-butyl starter unit and a polyol system in which eight hydroxy/acyloxy carbons are contiguously connected. Except for its congener butyrolactol B, there exist no structurally related natural products to date. In this study, inspired by our previous genomic analysis, incorporation of 13C- and 2H-labeled precursors...

MoO3/ZnO mixtures obtained using polyol synthesis exhibit an enhanced photochromism.

Blasticidin A (1) and aflastatin A (2), Streptomyces metabolites with similar structures, are specific inhibitors of aflatoxin production by Aspergillus parasiticus. The stereochemistry of the polyol fragment of 1 (3a) containing ten chiral centers was elucidated by applying acetonide and MTPA methods to a variety of acetonide derivatives of 3a, which determined the absolute configuration of 3a...

We report the direct soft chemical synthesis and characterization of a family of face centered cubic (fcc) and partially ordered face centered tetragonal (fct) FePt nanoparticles (NPs) suitable for biomedical applications. Both fcc and partially ordered fct-FePt NPs are synthesized by employing a simple polyol method. By using polyvinyl pyrolidone (PVP) as a stabilizer in various ratios during ...
