Iron is a widely used metal due to its low cost and availability, but it susceptible corrosion in many circumstances. This can result economic environmental losses, negatively affect the physical chemical properties of metal. chapter provides background on iron archaeology introduces various inhibitors for protection. It starts with general overview metallurgy iron, followed by an in-depth expl...

development of inhibitor to factor viii is the most serious complication of hemophilia therapy. to determine the prevalence of inhibitors in iran hemophilia a patients exposed to blood products, 1280 hemophilia a patients (age range 9 months-84 years) were evaluated. all patients received several blood products such as fresh frozen plasma (ffp), cryoprecipitate, and factor viii. 635 of 1280 pat...

Substantial evidence has shown that most exogenous substances are metabolized by multiple cytochrome P450 (P450) enzymes instead of by merely one P450 isoform. Thus, multi-P450 inhibition leads to greater drug-drug interaction risk than specific P450 inhibition. Herein, we innovatively established an artificial neural network cascade (NNC) model composed of 23 cascaded networks in a ladder-like...

Cytoplasmic dyneins are motor proteins in the AAA+ superfamily that transport cellular cargos toward microtubule minus-ends. Recently, ciliobrevins were reported as selective cell-permeable inhibitors of cytoplasmic dyneins. As is often true for first-in-class inhibitors, the use of ciliobrevins has in part been limited by low potency. Moreover, suboptimal chemical properties, such as the poten...

The chemical diversity, binding specificity and propensity to interact with biological targets has inspired many researchers to utilize natural products as molecular probes. Almost all reported carbonic anhydrase inhibitors comprise a zinc binding group in their structure of which the primary sulfonamide moiety (-SO2NH2) is the foremost example and to a lesser extent the primary sulfamate (-O-S...

Alkyl substituted 2-halogen-4-nitro-phenols (like bromonitrothymol) are potent inhibitors of photosynthetic electron flow in chloroplasts. There inhibition site is identical to that of DCMU, though the phenols do not contain their essential chemical element responsible for inhibition nor do they follow their correlation of chemical structure and biochemical function. Binding of labelled metribu...

Endoplasmic reticulum (ER) stress activates the unfolded protein response and its dysfunction is linked to multiple diseases. The stress transducer IRE1α is a transmembrane kinase endoribonuclease (RNase) that cleaves mRNA substrates to re-establish ER homeostasis. Aromatic ring systems containing hydroxy-aldehyde moieties, termed hydroxy-aryl-aldehydes (HAA), selectively inhibit IRE1α RNase an...

Protein-protein interactions (PPI) are involved in vital cellular processes and are therefore associated to a growing number of diseases. But working with them as therapeutic targets comes with some major hurdles that require substantial mutations from our way to design drugs on historical targets such as enzymes and G-Protein Coupled Receptor (GPCR). Among the numerous ways we could improve ou...

A quantum chemical study of the corrosion inhibition properties of some organic inhibitormolecules, pyridine, 2-picoline, 3-picoline, 4-picoline, 2, 4-lutidine at the aluminum surface inhydrochloric acid (HCl) was carried out. The models of the inhibitors adsorption on the Al-surfacewere optimized with the HF and B3LYP level using the 6-31G and LANL2DZ basis sets fromthe program package Gaussia...

Selective and nonselective cytochromes P450 (P450) chemical inhibitors and monoclonal antibodies (mAbs) are routinely used to determine the contribution of P450 enzymes involved in the biotransformation of a drug. A fluorometric assay has been established using fluorescein diacetate as a model substrate to determine the effect of some commonly used P450 inhibitors and mAbs on human liver micros...
