N-Heterocyclic carbenes (NHCs) have become one of the most widely studied class of ligands in molecular chemistry and have found applications in fields as varied as catalysis, the stabilization of reactive molecular fragments, and biochemistry. More recently, NHCs have found applications in materials chemistry and have allowed for the functionalization of surfaces, polymers, nanoparticles, and discrete, well-defined clusters. In this review, we provide an in-depth look at recent advances in the use of NHCs for the development of functional materials.

Heat exchangers represent vital equipment for the production and heat recovery in thermal desalination processes. However, with operation under scale control practices, scale growth reduces the performance and efficiency. To restore this performance, acid cleaning is the most adopted and efficient descaling method. Usually, strong mineral acids are used for acid cleaning and corrosion inhibitor addition represents a necessity to protect the underlying metal. Development of cost?effective and low toxic corrosion inhibitors for acid cleaning purpose has, therefore, becomes an essential area of research. In the present work, acid cleaning corrosion inhibitors research and development efforts reported in scientific publications and patent inventions over the last thirty years is reviewed. The review strictly considers works directly related to acid cleaning (descaling) publications rather than the usual acid corrosion inhibition of metals. Critical knowledge gaps are identified and future research perspectives are highlighted.

A comparison synthesis of 1,2,3-triazoles bearing isoxazole ether was developed between conventional and microwave-assisted heating. Single/double 1,2,3-triazoles bearing isoxazole ether were synthesized by click reaction starting from substituted isoxazolyl alkyne compounds and substituted benzyl azide compounds or neopen-tylglycol diazide in the presence of copper(I) that in-situ generated. Herein, the effect of different catalysts on the yield was researched by conventional method, and the optimal catalyst was selected. The structures of all the synthe-sized compounds were confirmed by MS, FTIR, 1H and 13C NMR spectroscopies. Moreover, the crystal structure of 5-{[(1-benzyl-1H-1,2,3-triazol-4-yl)methoxy]methyl}-3-(4-fluorophenyl)isoxazole(2h) was determined.

Cutaneous drug reactions (CDR) are responsible for numerous minor to life-threatening complications. Though the exact mechanism for CDR is not completely understood, evidence suggests that bioactivation of drugs to reactive oxygen or nitrogen species is an important factor in the initiation of these reactions. Several CDR-inducing drugs having an arylamine functional group, such as sulfamethoxazole (SMX) and dapsone (DDS), undergo bioactivation to reactive arylhydroxylamine metabolites. These metabolites can generate cellular oxidative stress by forming reactive oxygen species (ROS). Several studies have demonstrated a higher cytotoxicity with DDS hydroxylamine (DDS-NOH) compared to SMX hydroxylamine (SMX-NOH). To investigate the role of differential ROS generation in the higher cytotoxicity of DDS-NOH, hydroxylamine metabolites of SMX and DDS were synthesized and ROS formation by these metabolites determined. DDS-NOH and its analogues/metabolites consistently resulted in higher ROS formation as compared to SMX-NOH. However, comparison of the ROS generation and cytotoxicity of a series of arylhydroxylamine analogues of DDS did not support a simple correlation between ROS generation and cell death. Numerous ROS scavengers were found to reduce metabolite-induced ROS formation, with differences in the potency between the agents. The decrease in DDS-NOH-induced ROS generation in NHEK with ascorbic acid, N-acetylcysteine, Trolox, and melatonin was 87, 86, 44, and 16%, respectively. Similarly, the cytotoxicity and adduct formation of DDS-NOH in NHEK was reduced in the presence of ascorbic acid. In summary, these studies show that arylhydroxylamine metabolites of SMX/DDS induce ROS generation in NHEK, though such generation is not directly related to cytotoxicity.

Regioselective nuclear bromination of aromatic compounds is investigated with N-bromosuccinimide as the brominating agent under UV irradiation to afford the corresponding brominated compounds. The reaction proceeds at ambient temperature (30 ± 2 C) without any catalyst. In most of the reactions, regioselectively mono-brominated products are obtained in good to high yields. The conversion and selectivity for bromination depend on the nature of the substituent on the aromatic ring.

Farnesoid X receptor acts as bile acid sensing transcription factor and has been identified as valuable molecular drug target to treat severe liver disorders, such as non-alcoholic steatohepatitis (NASH). Preclinical and clinical data indicate anti-fibrotic effects obtained with FXR activation that also appear promising for other fibrotic diseases beyond NASH. Strong efforts in FXR ligand discovery have yielded potent steroidal and non-steroidal FXR activators, some of which have been studied in clinical trials. While the structure-activity relationship of some FXR agonist frameworks have been studied extensively, the structural diversity of potent FXR activator chemotypes is still limited to a handful of well-studied compound classes. Together with safety concerns related to full therapeutic activation of FXR, this indicates the need for novel innovative FXR ligands with selective modulatory properties. This chapter evaluates FXR’s value as drug target with emphasis on fibrotic diseases, analyses FXR ligand recognition and requirements and focuses on the discovery and structural refinement of leading FXR activator chemotypes.

An process for epoxidizing diversely functionalized olefins by oxorhenium catalysis employs conditions which control water concentration. By controlling water concentration, one can maximize monoperoxo complex formation and increase turnover which subsequently reduces diol side products obtained from epoxide ring opening and increases the yield of the desired epoxide product. The optimal range of water concentrations is 0.50-80.0 mol %. Using less than 0.5 mol % water does not result in practical turnovers and 1.0 equivalent of water (or more) is detrimental to the lifetime of the active catalytic species formed. More particularly, there are four aspects to controlling water concentration: 1) anhydrous oxidants using trialkylsilyl peroxides and an in situ source of BTSP eliminating the need for its isolation; 2) water removal agents including molecular sieves (Aldrich, 3 A, 4 A) and common inorganic dehydrating agents; 3) rhenium catalysts; and 4) a boiling reactor process in the context of oxorhenium catalyzed epoxidation.
