Diffusion, partitioning, and binding of two aldose-reductase inhibitors (ARI) in the rat lens were investigated under in vitro conditions. A lipophilic ARI (CT-112) and a hydrophilic ARI (AD-5467) were used as model drugs. Under lens-uptake conditions, the drug concentration in the lens increased rapidly during the initial 10 hr and reached steady state (equilibrium) after 24 hr. Despite the eq...

The proteomic approach is a valuable tool to detect and identify proteins that are associated with cancer. In previous investigations on experimentally induced rat hepatomas, we detected aldose reductase-like protein (ARLP) as a highly significant marker protein. Our present study was intended to look for the presence of similar tumor-associated marker proteins on human hepatocellular carcinoma...

Diabetes mellitus has become a major health threat as a global rise in it has been seen. The chronic disease has afflicted over 171 million people worldwide in 2000 and the incidence is expected to grow steadily to 366 million by 2030. As of May 2008, an estimated 92 million adults in China of the most populous country were living with diabetes and 148 million adults with prediabetes [1]. Diabe...

WF-3681 was isolated from a cultured filtrate of Chaetomella raphigera as a novel inhibitor of aldose reductase. It was extracted with ethyl acetate and then purified with silica gel chromatography. Its molecular formula was determined to be C13H12O5 by elemental analysis and high resolution electron impact mass spectrometry. IC50 of WF-3681 was 2.5 X 10(-7) M for partially purified aldose redu...

A hallmark of early diabetic retinopathy is the selective loss of the retinal mural cells (pericytes) from vessels. Using antibodies prepared against purified human placental aldose reductase, the presence of the enzyme aldose reductase can be demonstrated immunohistochemically in the cytoplasm of retinal mural cells of trypsin-digested human retinal vessels. This enzyme, which reduces various ...

Diabetes is a disease, which has assumed vital public health importance because of the complications associated with it. Various mechanisms including polyol pathway along with a complex integrating paradigm have been implicated in glucose-mediated complications. Though polyol pathway was established as a major mechanism, precise pathogenesis of these complications is not yet completely elucidat...
