Corrosion control of metals is an important activity technical, economic, environmental, and aesthetical importance. The use inhibitors one the best options for protecting alloys against corrosion. This study involves investigation new effective polymeric material application corrosion inhibition on aluminium in acid medium using chemical electrochemical methods. Results obtained from weight lo...

hiv-1 integrase (in) enzyme, one of the three main enzymes of hiv-1, catalyzed the insertion of the viral dna into the genome of host cells. because of the lack of its homologue in human cells and its essential role in hiv-1 replication, in inhibition represents an attractive therapeutic target for hiv-1 treatment. since identification of in as a promising therapeutic target, a major progress h...

A series of 27 benzamidine inhibitors covering a wide range of biological activity and chemical diversity was analysed to derive a Linear Interaction Energy in Continuum Electrostatics (LIECE) model for analysing the thrombin inhibitory activity. The main interactions occurring at the thrombin binding site and the preferred binding conformations of inhibitors were explicitly biased by including...

The von Hippel-Lindau tumor suppressor protein is the substrate binding subunit of the VHL E3 ubiquitin ligase, which targets hydroxylated α subunit of hypoxia inducible factors (HIFs) for ubiquitination and subsequent proteasomal degradation. VHL is a potential target for treating anemia and ischemic diseases, motivating the development of inhibitors of the VHL:HIF-α protein-protein interactio...

Tumor cells, including leukemic cells, remodel their bioenergetic system in favor of aerobic glycolysis. This process is called "the Warburg effect" and offers an attractive pharmacological target to preferentially eliminate malignant cells. In addition, recent results show that metabolic changes can be linked to tumor immune evasion. Mouse models demonstrate the importance of this metabolic re...

The critical contribution of aquaporin-2 (AQP) to water homeostasis in mammals is highlighted by the severe concentrating defects seen in humans with mutations in the AQP2 gene and in mice that are AQP2 null or have loss-of-function mutations in AQP2.1,2 The role of the antidiuretic hormone vasopressin and its receptor, V2R, in the signaling cascade that leads to membrane accumulation of AQP2 i...

The fight against the emergence of mutant influenza strains has led to the screening of an increasing number of compounds for inhibitory activity against influenza neuraminidase. This study explores the chemical space of neuraminidase inhibitors (NAIs), which provides an opportunity to obtain further molecular insights regarding the underlying basis of their bioactivity. In particular, a large ...

A literature survey was performed of the methods of quantitative assessment of the activity and concentration of cathepsin D and its inhibitors. Usefulness of non-modified and modified proteins and synthetic peptides as measurement substrates was evaluated. The survey includes also chemical and immunochemical methods used to determine the distribution of cathepsin D and its inhibitors in cells ...

We explore the applicability of an additive treatment of substituent effects to the analysis and design of HIV protease inhibitors. Affinity data for a set of inhibitors with a common chemical framework were analyzed to provide estimates of the free energy contribution of each chemical substituent. These estimates were then used to design new inhibitors whose high affinities were confirmed by s...
