It is well-recognized that N-heterocyclic carbene (NHC) ligands have provided a new dimension to the design of homogeneous catalysts. Part of the success of this type of ligands resides in the limitless access to a variety of topologies with tuned electronic properties, but also in the ability of a family of NHCs that are able to adapt their properties to the specific requirements of individual catalytic transformations. The term “smart” is used here to refer to switchable, multifunctional, adaptable, or tunable ligands and, in general, to all those ligands that are able to modify their steric or electronic properties to fulfill the requirements of a defined catalytic reaction. The purpose of this review is to comprehensively describe all types of smart NHC ligands by focusing attention on the catalytically relevant ligand-based reactivity.

Photocatalytic depolymerization (PCDP) of rice husk (RH) over TiO 2 in H2O2 aqueous solution under ultraviolet irradiation was investigated. The reaction mixture was fractionated into different extracts by filtration and subsequent sequential extraction with different organic solvents. In total, 172 organic compounds were identified in the extracts with GC/MS. The compounds can be classified into alkanes, alkenes, arenes, non-substituted alkanols, substituted alkanols, alkenols, phenols, alkanals, alkenals, benzaldehydes, ketones, carboxylic acids, alkanoates, phthalates, nitrogen-containing organic compounds, sulfur-containing organic compounds and other species. Alkanes are the most abundant in the group components. They resulted from the degradation of waxes in RH. Aldehydes and ketones were also detected with high relative contents, most of which were derived from cellulose, hemicellulose and waxes. Phthalates and arenes resulted from lignin degradation. Lignin-wax and hemicellulose-wax interlinkages are proposed to be new structures. According to the species identified in the extracts, the mechanisms for photocatalytic oxidation of benzene ring-containing compounds are proposed. The PCDP of RH provides an alternative way to obtain value-added chemicals from biomass with low energy consumption and under eco-friendly conditions.

A new magnetic resonance imaging probe(Gd-NAPTA) with 2-amino-7-methyl-1, 8-naphthyridine as the nucleotide triggering site incorporating into gadolinium-based contrast agent through 2,6-dimethylpyridine linker, preferentially responding to guanosine 5?-triphosphate and adenine 5?-triphosphate has been developed. The formation of strong multi-hydrogen bonds between naphthyridine and nucleotide bases made the phosphate in guanosine 5?-triphosphate and adenine 5?-triphosphate positioned on a suitable site to coordinate to the lanthanide ion, such the substitute of the coordinated pyridine promotes the water molecule close to Gd center and the relaxivity increase of the contrast agent. The longitudinal relaxivity(r1) of Gd-NAPTA could linearly respond to the concentration of guanosine 5?-triphosphate and adenine 5?- triphosphate. The limit of detection (LOD) is about 0.03 mM. The negligible cytotoxicity and appropriate blood circulation time of Gd-NAPTA allow potential application of Magnetic Resonance Imaging in vivo.

Aim: The 1,8-naphthyridine CR80 (ethyl 5-amino-2-methyl-6,7,8,9-tetrahydrobenzo[b] [1,8]naphthyridine-3-carboxylate) has shown interesting neuroprotective properties in in vitro and in vivo models of neurodegeneration. In spite of these promising outcomes, the molecular and cellular mechanisms underlying CR80 actions need to be further explored. Materials & methods: We herein report the signal transduction pathways involved in developmental, neuroprotective and stress-activated processes, as well as the gene expression regulation by CR80 in SH-SY5Y neuroblastoma cells. Results: The CR80 exposure upregulated several antioxidant enzymes (HO-1, GSR, SQSTM1, and TRXR1) and anti-apoptotic proteins (Bcl-xL, Bcl-2, P21, and Wnt6). Conclusion: The observed changes in gene expression would afford new insights on the neuroprotective profile of CR80.

Aromatic N-heterocycles have been used in electrochemical CO2 reduction, but their precise role is not yet fully understood. We used first-principles quantum chemistry to determine how the molecular sizes and substituent groups of these molecules affect their standard redox potentials involving various proton and electron transfers. We then use that data to generate molecular Pourbaix diagrams to find the electrochemical conditions at which the aromatic N-heterocycle molecules could participate in multiproton and electron shuttling in accordance with the Sabatier principle. While one-electron standard redox potentials for aromatic N-heterocycles can vary significantly with molecule size and the presence of substituent groups, the two-electron and two-proton standard redox potentials depend much less on structural modifications and substituent groups. This indicates that a wide variety of aromatic N-heterocycles can participate in proton, electron, and/or hydride shuttling under suitable electrochemical conditions.

While IFN-based hepatitis C virus (HCV) treatment regimens required long treatment duration, they only achieved a limited cure rate in HCV-infected patients and were accompanied by significant therapy-based side effects. The first curative IFN-sparing therapies revolutionized HCV treatment by utilizing a cocktail of mechanistically orthogonal direct-acting antiviral (DAA) agents to achieve much higher cure rates in a shorter period of time and with fewer side effects. One of the drug targets that these therapies usually engaged was the HCV NS5A protein. This chapter reviews the Abbott/AbbVie HCV NS5A program, which discovered inhibitors of this protein using an in vitro phenotypic screen, validated the mechanism in vivo, and ultimately discovered two FDA-approved NS5A inhibitors ombitasvir (OMB) and pibrentasvir (PIB). OMB, a first-generation NS5A inhibitor, is a component of two FDA-approved IFN-sparing DAA therapies (Viekira Pak and Technivie) with approval to treat genotypes 1 and 4, respectively. PIB, a next-generation NS5A inhibitor included in AbbVie?s next-generation therapy Mavyret (or Maviret), prevents replication of HCV genotypes 1?6 and exhibits an improved resistance profile relative to other FDA-approved first-generation NS5A inhibitors.

An effective method for transition-metal-free postfunctionalization of thiazolo[3,2-c][1,3,5,2]oxadiazaborinine dyes via direct lithiation of the 1,3-thiazole ring was developed. The reaction allows valuable regioselective C-H modification of these N,O-chelated organoboron chromophores incorporating different groups, including C-, Hal-, Si-, S-, Se-, and Sn-substituents. As a result, a library of novel fluorescent 1,3-thiazole-based organoboron complexes has been synthesized and characterized. The influence of the donor/acceptor strength of the substituent E on the photophysical properties has been established. The compound with a bulky lipophilic substituent (SnBu3) exhibits a relatively high solid-state photoluminescence quantum yield of 44%.
