A series of nonsymmetrical 2,3-diaminoquinoxaline derivatives prepared straight-forwardly by the C-N coupling between chloro-quinoxaline (2,3-DCQ) and various amino substrates. Synthesized products (4a-z) with excellent purity (1HNMR) without performing flash column chromatography purification. Investigated antibacterial activity selected nine compounds against Gram-positive, Gram-negative bact...

Background: The present study has been designed with the aim of evaluating A-kinase anchoring proteins 3 (AKAP3)and Procollagen-Lysine, 2-Oxoglutarate 5-Dioxygenase 3 (PLOD3) gene mutations and prediction of 3D proteinstructure for ligand binding activity in the cases of non-obstructive azoospermic male.Materials and Methods: Clinically diagnosed cases of non-obstructive azoos...

Background: There is limited information on the 3D prediction and modeling of the colistin resistance-associated proteins PmrA/B TCS in Acinetobacter baumannii. We aimed to evaluate the stereochemical structure and domain characterization of PmrA/B in an A. baumannii isolate resistant to high-level colistin, using bioinformatics tools. Methods: The species of the isolate and its susceptibility ...

TAR DNA-binding protein 43 (TDP-43) is a DNA/RNA binding playing critical role in the regulation of transcription, splicing and RNA stability. Mutations TARDBP leading to aggregation, are suspected be characteristic feature various neurogenerative diseases. The lack well-characterized anti- TDP-43 antibodies acts as barrier establish reproducible research. In thi...

A set of 18 plasmid subclones of the Autographa californica nuclear polyhedrosis virus genome supports expression from a late viral promoter in transient expression assays (J. W. Todd, A. L. Passarelli, and L. K. Miller, J. Virol. 69:968-974, 1995). Using this set of plasmids, we have assigned a role for each of the 18 genes required for optimal late gene expression with respect to its involvem...

In this study, syntheses of new pyrimidine-coupled N-ß-glucosides and tetra-O-acetyl derivatives were carried out. All glycoconjugates investigated in comparison with known chemotherapeutic agents terms their antimicrobial anticancer functions DNA/protein binding affinities. Spectral data showed that all glycoside obtained by diastereoselectivity as ß-anomers. Both tested groups exhibited stron...

During infection by human cytomegalovirus (HCMV), the tumor suppressor protein p53, which promotes efficient viral gene expression, is stabilized. However, the expression of numerous p53-responsive cellular genes is not upregulated. The molecular mechanism used to manipulate the transcriptional activity of p53 during infection remains unclear. The HCMV proteins IE1, IE2, pUL44, and pUL84 likely...
