Unexpected Reactivity of [(η5‐1,2,4‐tBu3C5H2)Ni(η3‐P3)] towards Main Group Nucleophiles and by Reduction
Authors: Mädl Eric , Balázs Gábor , Peresypkina Eugenia V. , Scheer Manfred 
Published: April 2016

AbstractThe reduction of [Cp′′′Ni(η3‐P3)] (1; Cp′′′=η5‐1,2,4‐tBu3C5H2) with potassium produces the complex anion [(Cp′′′Ni)2(μ,η2:2‐P8)]2−(2), which contains a realgar‐like P8unit. The anionic triple‐decker sandwich complex [(Cp′′′Ni)2(μ,η3:3‐P3)]−(3) with a cyclo‐P3middle deck is obtained when1is treated with NaNH2as a nucleophile. Na[3] can subsequently be oxidized with AgOTf to the neutral triple‐decker complex [(Cp′′′Ni)2(μ,η3:3‐P3)] (4). In contrast,1reacts with LiPPh2to give the anionic compound [(Cp′′′Ni)2(μ,η2:2‐P6PPh2)]−(5), a complex containing a bicyclic P7fragment capped by two Cp′′′Ni units. Protonation of Li[5] with HBF4leads to the neutral complex [(Cp′′′Ni)2(μ,η2:2‐(HP6PPh2)] (6). Adding LiNMe2to1results in [Cp′′′Ni(η2‐P3NMe2)]−(7) becoming accessible, a complex which forms as a result of nucleophilic attack at the cyclo‐P3ring of1. The complexes K2[2], Na[3],4,6, and Li[7] were fully characterized and their structures determined by single‐crystal X‐ray diffraction.
Antifungal properties of chitosan–cobalt(II) complex and its potential on the suppression of damping‐off in cucumber seedlings
Authors: Yu Xueqing , Jing Yingjun , Xia Wenchen 
Published: April 2016

AbstractChitosan–cobalt(II) complex (CTS–Co) was prepared by the complexation of chitosan with cobalt(II) ions. Fourier transform infrared spectra showed that the amine and secondary –OH groups of chitosan were involved in the complexation with Co(II) ions. The resultant CTS–Co exhibited slightly lower thermal stability than chitosan according to the thermogravimetric analysis. Compared with chitosan, CTS–Co possessed much stronger in vitro antifungal activity. The minimum inhibitory concentrations of CTS–Co against three pathogenic fungi were 250–500 µg/mL, depending on the fungal species. CTS–Co induced the serious leakage of intracellular constituents, which demonstrates that the disturbance on the integrity of the cell membrane is a possible antifungal action of CTS–Co. Furthermore, CTS–Co treatment reduced significantly the disease incidence of damping‐off in cucumber seedlings, and the relative control effect reached 72.2–74.3% after 21‐day cultivation. Additionally, low molecular weight CTS–Co promoted the growth of cucumber seedlings. Our results suggest that CTS–Co is a possible antifungal agent and has promising potential on the control of pathogenic diseases in crop production. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.
Rhodol‐based far‐red fluorescent probe for the detection of cysteine and homocysteine over glutathione

Published: April 2016

AbstractThe simultaneous discrimination of cysteine (Cys), homocysteine (Hcy) and glutathione (GSH) is of great importance due to their roles in biology and close link to many diseases, especially via the development of a far‐red fluorescent probe that could be used for rapid, selective, and sensitive detection of all three. Herein, we report the characterization of a far‐red fluorescent probe with turn‐on fluorescence properties and visible color changes that could be used for the detection of cysteine and homocysteine over glutathione. In this study we found that the sensor could discriminate cysteine and homocysteine over glutathione within 20 min. Function of this probe was based on the conjugate addition–cyclization reaction and showed a low detection limit to cysteine and homocysteine. Upon the addition of cysteine and homocysteine, the absorption band at 592 nm rose gradually and fluorescence was detected at 645 nm. The color changed from colorless to blue and fluorescence changed from absent to strong red fluorescence, which could be differentiated by the naked eye. All these unique features make this probe particularly potentially favorable for use in cysteine/homocysteine sensing and bioimaging applications. Copyright © 2016 John Wiley & Sons, Ltd.

AbstractThe few studies that have examined rates of acute myeloid leukemia (AML) transformation in lenalidomide‐treated myelodysplastic syndrome (MDS) patients have been limited to deletion 5q MDS. The association between lenalidomide and subsequent primary malignancies (SPMs) in MDS patients has not been evaluated previously. We conducted a retrospective cohort study to evaluate the risk of both SPM and AML in association with lenalidomide. A cohort of MDS patients (n = 1248) treated between 2004 and 2012 at Moffitt Cancer Center were identified, and incident cases of SPM and AML transformation were ascertained. Using a nested case–control design, MDS controls were 1:1 matched to SPM (n = 41) and AML (n = 150) cases, on age and date of MDS diagnosis, gender, follow‐up time, IPSS, and del (5q). Associations between lenalidomide and (1) SPM incidence and (2) AML transformation were estimated with hazards ratios (HR) and 95% confidence intervals (CIs) in the cohort and odds ratios (OR) in the case–control analysis. SPM incidence did not differ significantly between cohort MDS patients treated with (0.7 per 100 person‐years) or without lenalidomide (1.4 per 100 person‐years) (HR = 1.04, 95% CI = 0.40–2.74), whereas a significantly reduced SPM risk was observed in the case–control sample (OR = 0.03, 95% CI = <0.01–0.63). Lenalidomide was not associated with AML transformation in the cohort analysis (HR = 0.75, 95% CI = 0.44–1.27) or in the case–control analyses (OR = 1.16, 95% CI = 0.52–2.56), after adjustment for potential confounders. Lenalidomide was not associated with increased risk of SPM or AML transformation in a large cohort of MDS patients mostly including nondeletion 5q MDS.
Investigating the effect of flexible constraints on the accuracy of self‐modeling curve resolution methods in the presence of perturbations
Authors: Rahimdoust Mojdehi Nahal , Sawall Mathias , Neymeyr Klaus , Abdollahi Hamid 
Published: April 2016

Self‐modeling curve resolution methods have continuously been improved during recent years. Many efforts have been made on curve resolution methods to reduce the rotational ambiguity by means of different types of constraints. Choosing proper constraints and cost functions is critically important for the reduction of the rotational ambiguity because the constraints have a direct influence on the accuracy of the area of feasible solution (AFS).In this work, we introduce a new improved cost function, which serves to apply nonnegativity, unimodality, equality, and closure constraints. We also investigate the reduction of the AFS under hard and soft constraints. Another point of this work is to evaluate the accuracy and precision of the reduced AFS in the presence of noise and perturbations, under hard and soft implementation of nonnegativity, unimodality, equality, and closure constraints. A comparison is given between the reduced AFS with soft constraints (small deviations from constraints are accepted) and the reduced AFS under hard constraints (restrictedly forced constraints). A graphical visualization of this comparison is presented for various model problems. The results show that an AFS computation with soft constraints provides more reliable results, especially in the presence of noise. The test problems substantiate significant advantages of soft constraints over hard constraints because the obtained profiles are closer to the potentially true noisy profiles, which contain small deviations from ideal responses. Using tunable parameters ϵ,γ,ω,δ is one of the advantages of soft constrained cost function that allows the small deviations from ideal responses. Ultimately, soft constraints can help to reduce the lack‐of‐fit, and they are a proper instrument to handle the effect of noise on the AFS. Copyright © 2016 John Wiley & Sons, Ltd.
Mechanical Motion of Chiral Azobenzene Crystals with Twisting upon Photoirradiation

Published: April 2016

AbstractThe photomechanical motion of chiral crystals of trans‐azobenzene derivatives with an (S)‐ and (R)‐phenylethylamide group was investigated and compared with a racemic crystal. Changes in the UV/Vis absorption spectra of the powdered crystals before and after UV irradiation were measured by using an optical waveguide spectrometer, showing that the lifetime of the cis‐to‐trans thermal back‐isomerization of the chiral crystals was faster than that of the racemic crystals. Upon UV irradiation, a long plate‐like chiral microcrystal bent away from the light source with a twisting motion. A square‐like chiral microcrystal curled toward the light with some twisting. Reversible bending of a rod‐like chiral microcrystal was repeatable over twenty‐five cycles. In contrast, bending of a plate‐like racemic microcrystal was small. A possible mechanism for the bending and twisting motion was discussed based on the optimized cis conformer determined by using calculations, showing that the bending motion with twisting is caused by elongation along the b axis and shrinkage along the a axis.

AbstractThermolysis of [Cp*Ru(PPh2(CH2)PPh2)BH2(L2)] 1 (Cp*=η5‐C5Me5; L=C7H4NS2), with terminal alkynes led to the formation of η4‐σ,π‐borataallyl complexes [Cp*Ru(μ‐H)B{R‐C=CH2}(L)2] (2 a–c) and η2‐vinylborane complexes [Cp*Ru(R‐C=CH2)BH(L)2] (3 a–c) (2 a, 3 a: R=Ph; 2 b, 3 b: R=COOCH3; 2 c, 3 c: R=p‐CH3‐C6H4; L=C7H4NS2) through hydroboration reaction. Ruthenium and the HBCC unit of the vinylborane moiety in 2 a–c are linked by a unique η4‐interaction. Conversions of 1 into 3 a–c proceed through the formation of intermediates 2 a–c. Furthermore, in an attempt to expand the library of these novel complexes, chemistry of σ‐borane complex [Cp*RuCO(μ‐H)BH2L] 4 (L=C7H4NS2) was investigated with both internal and terminal alkynes. Interestingly, under photolytic conditions, 4 reacts with methyl propiolate to generate the η4‐σ,π‐borataallyl complexes [Cp*Ru(μ‐H)BH{R‐C=CH2}(L)] 5 and [Cp*Ru(μ‐H)BH{HC=CH‐R}(L)] 6 (R=COOCH3; L=C7H4NS2) by Markovnikov and anti‐Markovnikov hydroboration. In an extension, photolysis of 4 in the presence of dimethyl acetylenedicarboxylate yielded η4‐σ,π‐borataallyl complex [Cp*Ru(μ‐H)BH{R‐C=CH‐R}(L)] 7 (R=COOCH3; L=C7H4NS2). An agostic interaction was also found to be present in 2 a–c and 5–7, which is rare among the borataallyl complexes. All the new compounds have been characterized in solution by IR, 1H, 11B, 13C NMR spectroscopy, mass spectrometry and the structural types were unequivocally established by crystallographic analysis of 2 b, 3 a–c and 5–7. DFT calculations were performed to evaluate possible bonding and electronic structures of the new compounds.

AbstractSix new (2, 4–8) and two known polyketides with a basic structure of an anthraquinone‐xanthone were isolated from mycelia and culture broth of the fungus Engyodontium album strain LF069. The structures and relative configurations of these compounds were established by spectroscopic means, and their absolute configurations were defined mainly by comparison of quantum chemical TDDFT calculated and experimental ECD spectra. Compounds 2 and 4–8 were given the trivial names engyodontochone A (2) and B–F (4–8). Compounds 5–8 represent the first example of a 23,28 seco‐beticolin carbon skeleton. The relative and absolute configurations of two known substances JBIR‐97/98 (1) and JBIR‐99 (3) were determined for the first time. All isolated compounds were subjected to bioactivity assays. Compounds 1–4 exhibited inhibitory activity against methicillin‐resistant Staphylococcus aureus (MRSA) that was 10‐fold stronger than chloramphenicol.

Abstract32‐Hetero‐5,6‐dimethoxyphenanthrisapphyrins—macrocycles that link structural features of polycylic aromatic hydrocarbons and expanded porphyrins—were obtained in a straightforward [3+1] condensation reaction of dimethoxyphenanthritripyrrane and 2,5‐bis(arylhydroxymethyl)heterocyclopentadienes. The highly folded conformation of formally 4 n π‐electron macrocycles causes them to manifest only limited macrocyclic π conjugation as explored by means of NMR spectroscopic and X‐ray structural analyses, and supported by DFT calculations. Although protonation does not change their π‐conjugation characteristics, the cleavage of ether groups at the phenanthrenylene moiety yields nonaromatic 32‐hetero‐5,6‐dioxophenanthrisapphyrins.
