Cockayne syndrome (complementation groups A and B) is a rare autosomal recessive DNA repair disorder characterized by photosensitive skin and severely impaired physical and intellectual development. The Cockayne syndrome A and B proteins intervene in the repair of DNA modifications that block the RNA polymerase in transcribed DNA sequences (transcription-coupled repair). Recent results suggest that they also have Read More

This review will describe the recent advances in the field of aza-C-nucleosides with a particular emphasis on immucillins and related compounds. The review will cover both chemical and biological aspects concerning their preparation and/or occurrence in Nature as well as their biological properties which include glycosidase, glycosyl transferase, and nucleoside hydrolase and phosphorylase inhibition, among others. These Read More

The cytokine granulocyte colony-stimulating factor (G-CSF) is produced by numerous cell types including immune and endothelial cells. G-CSF binding to its receptor G-CSF-R which belongs to the cytokine receptor type I family depends on the interaction of alpha-helical motifs of the former and two fibronectin type III as well as an immunoglobulin-like domain of the latter. It activates several signalling transduction pathways i Read More

Adhesion is a hallmark of haematological and solid cancer cells. All five classes of cell adhesion molecules (CAM) - integrins, cadherins, immunoglobulin-like CAMs, selectins and CD44s - are characteristically dysregulated in human cancer. Adhesion enables and promotes cancer-defining biological processes like growth, survival, migration, extravasation, homing, and metastasis. Furthermore, cell adhesion mediat Read More

Aggressive immunity characterized by the motion of cytotoxic T lymphocytes (CTLs), T helper (Th) 1 cells, and natural killer (NK) cells is the first line of defense against intracellular microorganism invasion and tumor formation. In patients with infectious diseases and tumors, aggressive immunity is often attenuated by immune suppressive effects provided by regulatory T (Treg) cells including CD4+ CD25+ forkhead-box (fox) p3+ Read More

Arbidol (ARB; ethyl-6-bromo-4-[(dimethylamino)methyl]-5-hydroxy-1-methyl-2-[(phenylthio)methyl]-indole-3-carboxylate hydrochloride monohydrate), is a Russian-made potent broad-spectrum antiviral with demonstrated activity against a number of enveloped and non-enveloped viruses. ARB is well known in Russia and China, although to a lesser extent in western countries. Unlike other broad-spectrum antivirals, Read More

Endometriosis, a chronic gynecologic disease frequently resulting in chronic pelvic pain, severe dysmenorrhoea, and subfertility, is defined as the presence of endometrial tissue at extrauterine locations, most commonly on the peritoneum and ovaries. Conclusive diagnosis requires laparoscopic surgery followed by histological confirmation. The treatment options -at present- are limited to hormonal therapies and/or Read More

Virtual screening (VS) is an important component of cheminformatics and molecular modeling. An abundance of structural information, indicated by both the ever-increasing availability of 3-dimensional (3D) protein structures and the readiness of free conformational databases of commercially available compounds, such as ZINC, supplies a broad platform for VS. At the same time, new technology enables the impl Read More

Obesity is a chronic disease characterized by the accumulation of excess adipose tissue associated with an increased risk of multiple morbidities and mortality. At the present time, only three drugs have been approved by the Food and Drug Administration (FDA) for the treatment of obesity. Agonists and antagonists of some of the substances implicated in the regulation of energy homeostasis represent opportunities for anti- Read More
