Purpose: Recombinant human growth hormone (rhGH) has been used to improve growth in children with Noonan syndrome (NS). This study aimed to investigate the efficacy of rhGH therapy in Korean children with NS. Methods: Seventeen prepubertal children (10 boys, 7 girls) with NS who received rhGH therapy for at least 3 years between 2008 and 2017 were included. To compare the response, age- and sex-matched children with GH deficiency (GHD; n=31) were included. Height and growth velocity before and during treatment were analyzed. Results: The mean age of NS patients was 6.34 +/- 2.32 years. After treatment, the height standard deviation score (SDS) increased from -2.93 +/- 0.81 to -1.51 +/- 1.00 in patients with NS and from -2.45 +/- 0.42 to -1.09 +/- 0.47 in patients with GHD. There were no significant differences in growth velocity or change in height SDS between patients with NS and GHD. Growth velocity in the first year of treatment was higher in patients with PTPN11 mutations than those without PTPN11 mutations, but the change in height SDS was not significantly different between those 2 groups. Conclusion: rhGH therapy can increase linear growth in prepubertal children with NS. The growth response between patients with NS and patients with GHD was not significantly different. Furthermore, we observed that lower doses of growth hormone have a similar effect on height compared to previous studies in patients with NS. Our study indicates that rhGH treatment is useful for growth promotion.

Historically accessed through two-electron, anionic chemistry, ketones, alcohols, and amines are of foundational importance to the practice of organic synthesis. After placing this work in proper historical context, this Article reports the development, full scope, and a mechanistic picture for a strikingly different way of forging such functional groups. Thus, carboxylic acids, once converted to redox-active esters (RAEs), can be utilized as formally nucleophilic coupling partners with other carboxylic derivatives (to produce ketones), imines (to produce benzylic amines), or aldehydes (to produce alcohols). The reactions are uniformly mild, operationally simple, and, in the case of ketone synthesis, broad in scope (including several applications to the simplification of synthetic problems and to parallel synthesis). Finally, an extensive mechanistic study of the ketone synthesis is performed to trace the elementary steps of the catalytic cycle and provide the end-user with a clear and understandable rationale for the selectivity, role of additives, and underlying driving forces involved.

Herein, we report the synthesis and application of a Zn-Bp-BTC MOF (Bp – -4,4′-bipyridine; BTC -1,3,5-benzene tricarboxylic acid; MOF -metal organic framework) as a heterogeneous catalyst for mediating organic reactions. Initially, conditions were optimized for the Knoevenagel condensation reaction using Zn-Bp-BTC as a heterogeneous catalyst by varying the solvent, temperature and catalyst loading. Although the reaction proceeded at room temperature using methanol as the solvent, 60 degrees C offered the best yield in a shorter duration. Under optimized reaction conditions, a wide range of alpha, beta-unsaturated dicyano compounds were prepared from the corresponding carbonyl precursor and malononitrile, the active methylene counterpart. Systematic investigation was also carried out to assess the role of the ligand and metal salt in the Knoevenagel condensation reaction. It was found that the Zn-Bp-BTC MOF catalyzed the reaction efficiently in comparison to its analogue Zn-BTC MOF and precursor Zn(NO3)(2) center dot 6H2O. Finally, catalytic recycling and stability studies showed that the catalyst is able to mediate the reaction for up to five consecutive cycles without undergoing any significant chemical or morphological changes. Further, the catalyst was tested for its efficacy in a multi-component reaction (MCR). A MCR with the Zn-Bp-BTC MOF as the catalyst afforded good yields and there was no reaction in the absence of the catalyst. Similarly, the catalyst was tested for its efficiency in benzimidazole synthesis.

In this work, with the available solid-liquid equilibrium (SLE) data of six aromatic carboxylic acids, aromatic dicarboxylic acid isomers (terephthalic acid (TPA), isophthalic acid (IPA), and phthalic acid (PA)), and methyl benzoic acid isomers (m-toluic acid (m-TA), o-toluic acid (o-TA), and p-toluic acid (p-TA)) in acetic acid (HOAc) + water (H2O) solvent mixtures, the relationship between the molecular structure of the above aromatic carboxylic acids and the solubility of them in HOAc + H2O solvent mixtures is discussed. It could be found that among the aromatic dicarboxylic acid isomers and methyl benzoic acid isomers, TPA and p-TA have the lowest solubility in the same solvent and temperature, respectively. Meanwhile, three new groups, p-ArCOOH, m-ArCOOH, and o-ArCOOH, in the UNIFAC (Dortmund) model were first defined to distinguish the influence of the positions of ArCOOH on the thermodynamic properties of aromatic carboxylic acid isomers, which indicates that ArCOOH is located in the para, meta, and ortho positions of the ArCOOH or ArCH3 groups, respectively. Then, the interaction parameters of ArCOOH, p-ArCOOH, m-ArCOOH, and o-ArCOOH with other involved groups in the solvent systems are first obtained by regressing these available SLE data. By using the new defined group, the UNIFAC (Dortmund) model was used to correlate SLE data for the above ternary systems, and trimesic acid + HOAc + H2O systems agree with the experimentally measured results satisfactorily.

Herein, a novel ON-OFF colorimetric and fluorometric chemosensor; 1N-allyl-2-(2, 5-dimethoxyphenyl)-4, 5-diphenyl-1H-imidazole (ADPPI), was constructed for sequential determination of Cu2+ and S2- ions in aqueous media. The interaction between chemosensor ADPPI and different metal cations was investigated using UV-VIS and fluorimetric spectroscopy. ADPPI showed a favorable and good interaction with Cu2+ ions producing blue colored solution peaked at 610 nm with blue fluorescence at lambda(em) = 447 nm. The produced complex between Cu2+ ions and ADPPI can be used as a cascade probe for detection of S2- ions. The detection limits (LODs) were 1.01 nM and 1.25 mu M for Cu2+ and S2- ions, respectively (the lowest between the family of colorimetric and fluorometric chemosensors). To further increase the applicability of the proposed method, Cu2+ and S2- ions concentrations were measured in environmental water samples. (c) 2019 Elsevier B.V. All rights reserved.

The front cover picture, provided by Burkhard Konig et al., illustrates how iodine solutions block most of the incoming light with the exception of a small part at the edge of the visible light spectral region. This spectral window (385-415 nm) with low absorptivity allows irradiation of an inexpensive anthraquinone photocatalyst, which can promote the iodination of electron-rich arenes and heteroarenes with high regioselectivity and good to excellent yields. Details are reported in the full paper on pages XXXX-XXXX (R. Narobe, S. J. S. Dusel, J. Iskra, B. Konig, Adv. Synth. Catal. 2019, 361, XXXX-XXXX;. DOI: 10.1002/adsc.201900298).

Photochemistry provides a sustainable pathway for organic transformations by inducing radical intermediates from substrates through electron transfer process. However, progress is limited by heterogeneous photocatalysts that are required to be efficient, stable, and inexpensive for long-term operation with easy recyclability and product separation. Here, we report that boron carbonitride (BCN) ceramics are such a system and can reduce organic halides, including (het)aryl and alkyl halides, with visible light irradiation. Cross-coupling of halides to afford new C-H, C-C, and C-S bonds can proceed at ambient reaction conditions. Hydrogen, (het)aryl, and sulfonyl groups were introduced into the arenes and heteroarenes at the designed positions by means of mesolytic C-X (carbon-halogen) bond cleavage in the absence of any metal-based catalysts or ligands. BCN can be used not only for half reactions, like reduction reactions with a sacrificial agent, but also redox reactions through oxidative and reductive interfacial electron transfer. The BCN photocatalyst shows tolerance to different substituents and conserved activity after five recycles. The apparent metal-free system opens new opportunities for a wide range of organic catalysts using light energy and sustainable materials, which are metal-free, inexpensive and stable.

A two-step one pot, experimentally simple protocol, based on readily available and inexpensive reagents allowed the conversion of nitro-arenes directly to N-aryl amides. A metal-free reduction of the nitro group, mediated by trichlorosilane, followed by the addition of an anhydride afforded the corresponding N-aryl carboxyamide, that was isolated after a simple aqueous work up in good-excellent yields. When the methodology was applied to the reaction with gamma-butyrolactone, the desired N-aryl butanamide derivative was obtained, featuring a chlorine atom at the gamma-position, a functionalized handle that can be used for further synthetic manipulation of the reaction product. Such an intermediate has already been employed as a key advanced precursor of pharmaceutically active compounds.
