Inhibitors of glucosamine-6-phosphate synthase as potential antifungal drugs.
PublikacjaPrzedstawiono stan obecny i perspektywy zastosowania inhibitorów enzymu syntazy GlcN-6-P jako leków skutecznych w leczeniu grzybic układowych. Używając metod modelowania molekularnego zaprojektowano struktury inhibitorów enzymu należących do dwóch grup strukturalnych: analogów glutaminy oraz analogów stanu przejściowego reakcji katalizowanej przez enzym. Opracowano metody syntezy pochodnych zoptymalizowanych inhibitorów, wykazujących...

Procognitive activity of nitric oxide inhibitors and donors in animal models
PublikacjaNitric oxide is a small gaseous molecule that plays important roles in the majority of biological functions. Impairments of NO-related pathways contribute to the majority of neurological disorders, such as Alzheimer’s disease (AD), and mental disorders, such as schizophrenia. Cognitive decline is one of the most serious impairments accompanying both AD and schizophrenia. In the present study, the activities of NO donors, slow (spermine...

Diaryl Sulfide Derivatives as Potential Iron Corrosion Inhibitors: A Computational Study
PublikacjaThe present work aimed to assess six diaryl sulfide derivatives as potential corrosion inhibitors. These derivatives were compared with dapsone (4,4′-diaminodiphenyl sulfone), a common leprosy antibiotic that has been shown to resist the corrosion of mild steel in acidic media with a corrosion efficiency exceeding 90%. Since all the studied compounds possess a common molecular backbone (diphenyl sulfide), dapsone was taken as the...

Carboxylic acids as efficient corrosion inhibitors of aluminium alloys in alkaline media
PublikacjaThe efficiency of AA5754 aluminium alloy corrosion inhibition achieved with maleic, malic, succinic, tartaric, citric, tricarballylic acids and serine in alkaline environment (pH 11) was examined. Selected corrosion inhibitors are characterized by different numbers and distribution of carbonyl and hydroxyl groups within their molecules. We have proposed and verified a novel approach for determining the adsorption isotherms based...

N-Alkyl Derivatives of L-Glutamine As Inhibitors of Glutamine - Utilizing Enzymes
PublikacjaA general facile method to synthesize the N-gamma-alkyl and N-gamma,N-gamma-dialkyl derivatives of L-glutamine (1a-d) from L-glutamic acid as a starting substrate is presented. The obtained compounds are shown to inhibit three diferent glutamine-utilizing enzymes, namely: glutaminase, gamma-glutamyl transpeptidase, and glucosamine-6-phosphate synthase, with inhibitory constants within the milimolar range.

Antifungal activity of L-homoserine O-acetyltransferase (CaMet2p) inhibitors.
Dane BadawczeThe dataset contains a set of optical densities at 600 nm measured at microplate reader to determine the rate of fungal growth in the presence of Candida albicans homoserine O-acetyltransferase inhibitors. Antifungal activities were determined against several strains from Candida spp. and others by the modified M27-A3 method specified by the CLSI. We...

Geometry optimization of steroid sulfatase inhibitors - the influence on the free binding energy with STS
PublikacjaIn the paper we review the application of two techniques (molecular mechanics and quantum mechanics) to study the influence of geometry optimization of the steroid sulfatase inhibitors on the values of descriptors coded their chemical structure and their free binding energy with the STS protein. We selected 22 STS-inhibitors and compared their structures optimized with MM+, PM7 and DFT B3LYP/6–31++G* approaches considering separately...

Inhibitors of glucosamine-6-phosphate synthase as potential antimicrobials or antidiabetics – synthesis and properties
PublikacjaGlucosamine-6-phosphate synthase (GlcN-6-P synthase) is known as a promising target for antimicrobial agents and antidiabetics. Several compounds of natural or synthetic origin have been identified as inhibitors of this enzyme. This set comprises highly selective L-glutamine, amino sugar phosphate or transition state intermediate cis-enolamine analogues. Relatively low antimicrobial activity of these inhibitors, poorly penetrating...

Application 2D Descriptors and Artificial Neural Networks for Beta-Glucosidase Inhibitors Screening
PublikacjaBeta-glucosidase inhibitors play important medical and biological roles. In this study, simple two-variable artificial neural network (ANN) classification models were developed for beta-glucosidase inhibitors screening. All bioassay data were obtained from the ChEMBL database. The classifiers were generated using 2D molecular descriptors and the data miner tool available in the STATISTICA package (STATISTICA Automated Neural...
