Effective Tuning of Ketocyanine Derivatives through Acceptor Substitution
Authors: Poe Ambata , Della Pelle Andrea , Byrnes Sean , Thayumanavan S. 
Published: April 2015

AbstractA series of ketocyanine derivatives possessing bis(diarylamino)fluorenyl donors and variable acceptors installed at the bridging carbon atom were synthesized to investigate how the electronic structure of the dye can be systemically tuned through stabilization of the cyanine‐like character of the donor by increasing the acceptor strength. Analysis of the 1H NMR spectra indicates that the “charge‐separated” species dominates in these dyes, given that carbons possessing a positive or negative charge in the resonance structures of this state purposefully shift downfield or upfield, respectively, depending on the strength of the acceptor moiety. In DAA‐Fl‐PI, the acceptor strength and the gain of acceptor aromaticity indicates a predisposition of the separated state, indicated by asymmetry in the 1H NMR spectrum, as well as uneven distribution of the HOMO on the fluorenyl donor.
Highly Efficient AuPd/Carbon Nanotube Nanocatalysts for the Electro‐Fenton Process

Published: April 2015

AbstractDevelopment of novel nanocatalysts for the highly efficient in situ synthesis of H2O2 from H2 and O2 in the electro‐Fenton (EF) process has potential for the remediation of water pollution. In this work, AuPd/carbon nanotube (CNT) nanocatalysts were successfully synthesized by the facile aggregation of AuPd bimetals on CNTs. Characterization by X‐ray diffraction, transmission electron microscopy, and X‐ray photoelectron spectroscopy indicated that pure AuPd bimetallic heterogeneous nanospheres (≈20 nm) were well dispersed outside the CNTs, which resulted in better catalytic performance than Pd/CNTs alone: 0.36 M H2O2 was synthesized; 0.05 M Fe2+ optimally initiated the EF process due to the superior in situ Fe2+ regeneration; and the organic pollutant removal reached 100 % at 37 min, with a pseudo‐first‐order kinetic constant k1=0.051 min−1. Moreover, structural insights before/after catalysis revealed that Au strengthened the construction of the nanocrystals, avoided negative deactivation caused by AuPd agglomeration, and immobilized the active Pd(111). The catalytic stability of AuPd/CNTs over ten cycles implied long durability and promising applications of this material.
Prediction of Boron–Boron Triple‐Bond Polymers Stabilized by Janus‐Type Bis(N‐heterocyclic) Carbenes
Authors: Fantuzzi Felipe , Chaer Nascimento Marco A. 
Published: April 2015

AbstractA class of polymeric compounds containing boron–boron triple bonds stabilized by N‐heterocyclic biscarbenes is proposed. Since a triply bonded B2 is related to its third excited state, the predicted macromolecule would be composed by several units of an electronically excited first‐row homonuclear dimer. Moreover, it is shown that the replacement of biscarbene with N2 or CO as spacers could change the bonding profile of the boron–boron units to a cumulene‐like structure. Based on these results, different types of diboryne polymers are proposed, which could lead to an unprecedented set of boron materials with distinct physical properties. The novel diboryne macromolecules could be synthesized by the reaction of Janus‐type biscarbenes with tetrabromodiborane, B2Br4, and sodium naphthalenide, [Na(C10H8)], similarly to Braunschweig’s work on the room temperature stable boron–boron triple bond compounds (Science, 2012, 336, 1420).
Beyond Stereoselectivity, Switchable Catalysis: Some of the Last Frontier Challenges in Ring‐Opening Polymerization of Cyclic Esters
Authors: Guillaume Sophie M. , Kirillov Evgueni , Sarazin Yann , Carpentier Jean‐François 
Published: April 2015

AbstractMetal‐based catalysts and initiators have played a pivotal role in the ring‐opening polymerization (ROP) of cyclic esters, thanks to their high activity and remarkable ability to control precisely the architectures of the resulting polyesters in terms of molar mass, dispersity, microstructure, or tacticity. Today, after two decades of extensive research, the field is slowly reaching maturity. However, several challenges remain, while original concepts have emerged around new types or new applications of catalysis. This Review is not intended to comprehensively cover all of these aspects. Rather, it provides a personal overview of the very recent progress achieved in some selected, important aspects of ROP catalysis—stereocontrol and switchable catalysis. Hence, the first part addresses the development of new metal‐based catalysts for the isoselective ROP of racemic lactide towards stereoblock copolymers, and the use of syndioselective ROP metal catalysts to control the monomer sequence in copolymers. A second part covers the development of ROP catalysts—primarily metal‐based catalysts, but also organocatalysts—that can be externally regulated by the use of chemical or photo stimuli to switch them between two states with different catalytic abilities. Current challenges and opportunities are highlighted.

Published: April 2015

AbstractEin Ansatz zur Simulation von Trennprozessen in Packungskolonnen basiert auf Analogien zwischen komplexen, in realen Apparaten vorliegenden, und geometrisch vereinfachten Strömungsformen und ist daher als Ansatz der Hydrodynamischen Analogien (HA) bekannt. In dieser Arbeit wurde der HA‐Ansatz für die Modellierung reaktiver Absorption von CO2 in wässriger Natronlauge bei vorliegender turbulenter Gasströmung verwendet. Es wurden umfangreiche Absorptionsversuche durchgeführt, bei denen CO2‐Konzentrationen in der Gasphase über die Kolonnenhöhe vermessen wurden. Der HA‐Ansatz konnte anhand dieser experimentellen Daten erfolgreich validiert werden.

BACKGROUNDReceptors in tumor blood vessels are attractive targets for ligand‐directed drug discovery and development. The authors have worked systematically to map human endothelial receptors (“vascular zip codes”) within tumors through direct peptide library selection in cancer patients. Previously, they selected a ligand‐binding motif to the interleukin‐11 receptor alpha (IL‐11Rα) in the human vasculature.METHODSThe authors generated a ligand‐directed, peptidomimetic drug (bone metastasis‐targeting peptidomimetic‐11 [BMTP‐11]) for IL‐11Rα–based human tumor vascular targeting. Preclinical studies (efficacy/toxicity) included evaluating BMTP‐11 in prostate cancer xenograft models, drug localization, targeted apoptotic effects, pharmacokinetic/pharmacodynamic analyses, and dose‐range determination, including formal (good laboratory practice) toxicity across rodent and nonhuman primate species. The initial BMTP‐11 clinical development also is reported based on a single‐institution, open‐label, first‐in‐class, first‐in‐man trial (National Clinical Trials number NCT00872157) in patients with metastatic, castrate‐resistant prostate cancer.RESULTSBMTP‐11 was preclinically promising and, thus, was chosen for clinical development in patients. Limited numbers of patients who had castrate‐resistant prostate cancer with osteoblastic bone metastases were enrolled into a phase 0 trial with biology‐driven endpoints. The authors demonstrated biopsy‐verified localization of BMTP‐11 to tumors in the bone marrow and drug‐induced apoptosis in all patients. Moreover, the maximum tolerated dose was identified on a weekly schedule (20‐30 mg/m2). Finally, a renal dose‐limiting toxicity was determined, namely, dose‐dependent, reversible nephrotoxicity with proteinuria and casts involving increased serum creatinine.CONCLUSIONSThese biologic endpoints establish BMTP‐11 as a targeted drug candidate in metastatic, castrate‐resistant prostate cancer. Within a larger discovery context, the current findings indicate that functional tumor vascular ligand‐receptor targeting systems may be identified through direct combinatorial selection of peptide libraries in cancer patients.

Published: April 2015

SummaryCloud environments have become a standard method for enterprises to offer their applications by means of web services, data management systems, or simply renting out computing resources. In our previous work, we presented how we can use a modeling language together with the new features of JAVA 8 to overcome certain drawbacks of data structures and synchronization mechanisms in parallel applications. We extend this solution into a design pattern that allows application‐specific optimizations in a distributed setting. We validate this integration using our previous case study of the Prime Sieve of Eratosthenes and illustrate the performance improvements in terms of speed‐up and memory consumption.

Interaction of Ln3+ with Methyl‐Substituted Cucurbit[n]urils (n=5,6) Derived from 3α‐Methyl Glycoluril
Authors: Wang Chuan‐Zeng , Zhao Wen‐Xuan , Zhang Yun‐Qian , Xue Sai‐Feng , Tao Zhu , Zhu Qian‐Jiang 
Published: April 2015

AbstractThe interactions between a series of lanthanide cations (Ln3+) and methyl‐substituted cucurbiturils (SPMeQ[5] and SHMeQ[6]) derived from a 3α‐methyl glycoluril have been investigated. Single‐crystal X‐ray diffraction analysis revealed that both SPMeQ[5] and SHMeQ[6] selectively interact with certain lanthanide ions. SPMeQ[5] forms coordination capsules in the presence of [CdCl4]2−. The Ln3+ cations that interact are the four light lanthanides, La3+, Ce3+, Pr3+, and Nd3+, whereas the remaining lanthanide cations remain in solution. SHMeQ[6] formed adducts of SHMeQ[6] with aqua complexes of lanthanide cations ([Ln(H2O)8]3+); for SHMeQ[6]–Ln(NO3)3–CdCl2–HCl systems (Ln=Gd–Lu), no solid crystals were obtained from systems that contained La, Ce, Pr, Nd, Sm, or Eu. Whereas solid crystals of adducts of SHMeQ[6] with aqua complexes of lanthanide cations (Ln=Sm–Lu) formed SHMeQ[6]–Ln(NO3)3 systems in neutral solution, no solid crystals were obtained from systems that contained La, Ce, Pr, or Nd. These results suggest that SPMeQ[5]– and SHMeQ[6]–Ln(NO3)3 systems could be useful for the selective isolation of these lighter or heavier lanthanide cations from mixtures. Energy‐dispersive spectrometry indicated that the lighter or heavier lanthanide cations could be isolated from their heavier or lighter counterparts through interaction with SPMeQ[5] and SHMeQ[6].
