Authors: Tayo Lemmuel L. , Venault Antoine , Constantino Vryan Gil R. , Caparanga Alvin R. , Chinnathambi Arunachalam , Ali Alharbi Sulaiman , Zheng Jie , Chang Yung 
Published: May 2015

ABSTRACTThis works aims at (i) studying the antiadhesive properties and the hemocompatibility of poly[2‐(dimethylamino)ethyl methacrylate]‐co‐poly[(ethylene glycol)methacrylate] [poly(DMAEMA‐co‐PEGMA)] copolymers and (ii) investigating the insulin delivery kinetics through hydrogels at physiological pH. A series of poly(DMAEMA‐co‐PEGMA) hydrogels have been synthesized, and their controlled composition was confirmed by X‐ray photoelectron spectroscopy. Then, antibiofouling properties of hydrogels—fibrinogen, erythrocytes, and thrombocytes adhesion—are correlated to their molecular compositions through their hydrophilic properties. As DMAEMA/PEGMA ratio of 70/30 (D70) offers the best compromise between pH sensitivity and hemocompatibility, it is selected for investigating the kinetic rate of insulin release at physiological pH, and the diffusion coefficient of insulin in gel is found to be 0.64 × 10−7 cm2 s−1. Overall, this study unveils that poly(DMAEMA‐co‐PEGMA) copolymers are promising hemocompatible materials for drug delivery systems. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Coagulation factor IX regulates cell migration and adhesion in vitro

Published: May 2015

AbstractCoagulation factor IX is thought to circulate in the blood as an inactive zymogen before being activated in the coagulation process. The effect of coagulation factor IX on cells is poorly understood. This study aimed to evaluate the effects of intact coagulation factor IX and its cleavage fragments on cell behavior. A431 cells (derived from human squamous cell carcinoma), Pro5 cells (derived from mouse embryonic endothelial cells), Cos7 cells, and human umbilical vein endothelial cells were utilized in this study. The effects of coagulation factor IX and its cleavage fragments on cell behavior were investigated in several types of experiments, including wound‐healing assays and modified Boyden chamber assays. The effect of coagulation factor IX depended on its processing; full‐length coagulation factor IX suppressed cell migration, increased adhesion to matrix, and enhanced intercellular adhesion. In contrast, activated coagulation factor IX enhanced cell migration, suppressed adhesion to matrix, and inhibited intercellular adhesion. An activation peptide that is removed during the coagulation process was found to be responsible for the activity of full‐length coagulation factor IX, and the activity of activated coagulation factor IX was localized to an EGF domain of the coagulation factor IX light chain. Full‐length coagulation factor IX has a sedative effect on cells, which is counteracted by activated coagulation factor IX in vitro. Thus, coagulation factor IX may play roles before, during, and after the coagulation process.

Yolk‐Shell Porous Microspheres of Calcium Phosphate Prepared by Using Calcium L‐Lactate and Adenosine 5′‐Triphosphate Disodium Salt: Application in Protein/Drug Delivery
Authors: Ding Guan‐Jun , Zhu Ying‐Jie , Qi Chao , Sun Tuan‐Wei , Wu Jin , Chen Feng 
Published: May 2015

AbstractA facile and environmentally friendly approach has been developed to prepare yolk‐shell porous microspheres of calcium phosphate by using calcium L‐lactate pentahydrate (CL) as the calcium source and adenosine 5′‐triphosphate disodium salt (ATP) as the phosphate source through the microwave‐assisted hydrothermal method. The effects of the concentration of CL, the microwave hydrothermal temperature, and the time on the morphology and crystal phase of the product are investigated. The possible formation mechanism of yolk‐shell porous microspheres of calcium phosphate is proposed. Hemoglobin from bovine red cells (Hb) and ibuprofen (IBU) are used to explore the application potential of yolk‐shell porous microspheres of calcium phosphate in protein/drug loading and delivery. The experimental results indicate that the as‐prepared yolk‐shell porous microspheres of calcium phosphate have relatively high protein/drug loading capacity, sustained protein/drug release, favorable pH‐responsive release behavior, and a high biocompatibility in the cytotoxicity test. Therefore, the yolk‐shell porous microspheres of calcium phosphate have promising applications in various biomedical fields such as protein/drug delivery.
Aromatic Interactions in Organocatalyst Design: Augmenting Selectivity Reversal in Iminium Ion Activation
Authors: Holland Mareike C. , Metternich Jan Benedikt , Daniliuc Constantin , Schweizer W. Bernd , Gilmour Ryan 
Published: May 2015

AbstractSubstituting N‐methylpyrrole for N‐methyindole in secondary‐amine‐catalysed Friedel–Crafts reactions leads to a curious erosion of enantioselectivity. In extreme cases, this substrate dependence can lead to an inversion in the sense of enantioinduction. Indeed, these closely similar transformations require two structurally distinct catalysts to obtain comparable selectivities. Herein a focussed molecular editing study is disclosed to illuminate the structural features responsible for this disparity, and thus identify lead catalyst structures to further exploit this selectivity reversal. Key to effective catalyst re‐engineering was delineating the non‐covalent interactions that manifest themselves in conformation. Herein we disclose preliminary validation that intermolecular aromatic (CH–π and cation–π) interactions between the incipient iminium cation and the indole ring system is key to rationalising selectivity reversal. This is absent in the N‐methylpyrrole alkylation, thus forming the basis of two competing enantio‐induction pathways. A simple L‐valine catalyst has been developed that significantly augments this interaction.
Alloyed ZnS–CuInS2 Semiconductor Nanorods and Their Nanoscale Heterostructures for Visible‐Light‐Driven Photocatalytic Hydrogen Generation

Published: May 2015

AbstractA promising photocatalytic system in the form of heterostructured nanocrystals (HNCs) is presented wherein alloyed ZnS–CuInS2 (ZCIS) semiconductor nanorods are decorated with Pt and Pd4S nanoparticles. This is apparently the first report on the colloidal preparation and photocatalytic behavior of ZCIS–Pt and ZCIS–Pd4S nanoscale heterostructures. Incorporation of Pt and Pd4S cocatalysts leads to considerable enhancement of the photocatalytic activity of ZCIS for visible‐light‐driven hydrogen production.
Can Helical Peptides Unwind One Turn at a Time? ‐ Controlled Conformational Transitions in α,β2,3‐Hybrid Peptides
Authors: Balamurugan Dhayalan , Muraleedharan Kannoth M. 
Published: May 2015

AbstractUnfolding of helical trans‐β2,3‐hybrid peptides with (α–β)nα composition, when executed by increasing solvent polarity or temperature, proceeded in a systematic manner with the turns unwinding sequentially; C‐terminal region of these peptides were first to unwind and the process propagated towards N terminus with more and more β residues equilibrating from the gauche to the anti rotameric state across CαCβ. This is evidenced by clear change in their CβH signal splitting, 3JCαH–CβH values, and sequential disappearance of i,i+2 NOEs.
