N- and 2-substituted N-(phenylsulfonyl)glycines as inhibitors of rat lens aldose reductase

Abstract

A variety of N-(phenylsulfonyl)-N-phenylglycines 5, N-(phenylsulfonyl)-2-phenylglycines 6, and N-(phenylsulfonyl)anthranilic acids 7 were prepared as analogues of the N-(phenylsulfonyl)glycine 1 aldose reductase inhibitors. In the rat lens assay, several derivatives of 5 display greater inhibitory activity than the corresponding glycines 1, suggesting that N-phenyl substitution enhances affinity for aldose reductase. Enzyme kinetic evaluations of the 4-benzoylamino analogues of 5 and 1 demonstrate that these compounds produce inhibition by the same mechanism. However, the significant differences in relative inhibitory potencies between compounds of series 5 and 1 may indicate that these compounds do not interact with the inhibitor binding site in precisely the same manner. Evaluation of the individual enantiomers of series 6 reveals that the S isomers are substantially more active than the corresponding R isomers. Also, with the exception of the naphthalene analogue 6n, the S stereoisomers of this series display greater inhibitory potencies than the glycines 1. The anthranilates 7 generally are less active than the glycines 1, demonstrating that direct incorporation of an aromatic ring in the glycine side chain may result in a ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
