NJC Poster Prize Winners at Metals and Genetics Meeting

Three young scientists were recognized for their contributions at the 6th International Conference on Metals and Genetics, which took place earlier this year at the Indian Institute of Science in Bangalore.

The winners (in no particular order) of the NJC Poster Prizes awarded at this conference were:

Mr Vadde Ramu, National Chemical Laboratory, Pune
Poster title: New imaging reagents for lipid dense regions in live cells and the nucleus in fixed MCF-7 cells

The presented work is part of Vadde’s Ph.D. thesis, carried out under the supervision of Dr. Amitava Das. Vadde will be defending his thesis work this month and is moving to Jena for a post-doctoral position in October.

The presented research work demonstrated the design and synthesis of two new uracil (U) and 5-flurouracil (5-FU) labelled ruthenium(II)-polypyridyl based cellular imaging reagents. These two complexes were found to show affinity towards DNA in the nucleus of the PFA fixed cells. A large Stokes shift (λ = 160 nm) and an appreciably long-lived 3MLCT excited state (λ = 320 ns) in aq. buffer medium (pH 7.4) are other key features of these complexes. Unlike the common nuclear DNA staining reagents like DAPI, these low-cytotoxic reagents are found to be highly stable towards photo-bleaching upon irradiation with λ > 455 nm at the MLCT band for these complexes.

Mr Samsuzzoha Mondal, Tata Institute of Fundamental Research, Mumbai
Poster title: Sensing Signalling Phospholipids with ‘Lanthano-proteins’

Samsuzzoha is a Ph.D. student working in the group of Dr. Ankona Datta. He is in his final year and expects to defend his degree in mid-2017.

His present research is about developing fluorescent probes for imaging the crucial phospholipids involved in cell signaling processes. Currently available genetically encoded fluorescent probes lack ‘on-off’ sensing and have problems with background signal. Hence tracking the spatio-temporal dynamics of phospholipids in a live cellular process with those fluorescent proteins is challenging. The authors are addressing this issue by developing novel fluorescent probes with ‘turn on’ or ‘ratiometric’ fluorescence sensing. The poster presents a ‘lanthano’-protein based ‘turn on’ sensor for phosphatidylserine, a phospholipid involved in cell-death signals mediation and several other signaling processes. Additionally, a recently developed, cell permeable, ratiometric sensor for phosphoinositides, the most important signaling phospholipids in the cellular system, is demonstrated.


Ms Tandrila Das, Indian Institute of Science, Bangalore
Poster title: Vacancy-Engineered Nanoceria: Enzyme Mimetic Hotspots for the degradation of Nerve Agents

Tandrila did the work presented in the poster as a 5th year BS-MS student under the direction of Prof. Govindasamy Mugesh. She is now a 1st year student in the Tri-Institutional Ph.D. program in chemical biology offered by Weill Cornell Medicine, Memorial Sloan-Kettering Cancer Center and The Rockefeller University (all located in New York City).

The study of phosphotriesterase (PTE) enzymes and synthesis of its structural and functional mimics has been a long time interest of the lab. PTE enzymes degrade organophosphorus nerve agents, which are known to inhibit acetylcholine esterase, thus resulting in paralysis, respiratory failure, etc.  For her Master’s thesis, Tandrila worked on developing a nano-mimic of PTE enzyme. The poster work showed that vacancy engineered nanoceria (CeO2) with Ce in both +3 and +4 oxidation states very efficiently act as a catalyst to hydrolyze organophosphorus nerve agents like paraoxon, parathion, etc.

(The photo shows Tandrila on the left with co-author Dr Amit Vernekar, currently a post-doc in the Lippard group at MIT.)

Congratulations to the 3 laureates, and best wishes for continuing success in their research and careers.

NJC issue 07 now online

NJC July 2016 OFC NLigands - Dr Monchaud

This month’s issue includes a themed collection put together by guest editors Claude Gros and Franck Denat (Université Bourgogne Franche-Comté, France). It reports recent advances in the chemistry of Nitrogen Ligands, including organic, coordination, metal-organic and bioinorganic chemistry, and also materials science and catalysis. This themed issue follows the 6th EuCheMS Conference on Nitrogen Ligands held in Beaune in September 2015. The Editors and the NJC team are very grateful to all the authors (representing 13 countries) and reviewers of the 39 contributions to this themed issue.

Access the Editorial here.

We would like to thank Dr David Monchaud (Université Bourgogne Franche-Comté, France) for designing the outside cover. It illustrates an article reporting a palladated porphyrin named Pd·TEGPy. The authors show that its efficiency as a quadruplex-selective fluorescent dye relies on a structural design that endows it with attractive supramolecular and electronic properties and makes it an efficient turn-on, fluorescent stain thanks to a DNA-mediated sensitization mechanism that ensures a high level of specificity.

DNA structure-specific sensitization of a metalloporphyrin leads to an efficient in vitro quadruplex detection molecular tool
Pape Diaba Diabate, Aurélien Laguerre, Marc Pirrotta, Nicolas Desbois, Julien Boudon, Claude P. Gros and David Monchaud, New J. Chem., 2016, 40, 5683-5689. DOI: 10.1039/C6NJ01012A.

NJC IFC July 2016 - Dr HR Zhang

The inside cover is proposed by Dr Hai-Rong Zhang (Guangxi Normal University, China) to illustrate a paper showing the authors’ interest in finding novel non-platinum metal-based complexes with maximal beneficial antitumor properties and minimal side effects. In their study, Dr Zhang and his colleagues synthesize and structurally characterize two rhodium(III) complexes of 8-hydroxyquinoline (HOQ) and its derivative 5-bromo-8-hydroxyquinoline (HBrQ). They also screen the in vitro cytotoxicity against a series of human cancer cell lines and study the DNA binding properties of the best cytotoxic complex.

2015 Winners of the New Journal of Chemistry Poster Prize

New Journal of Chemistry is delighted to present the five winners of the NJC poster prizes awarded in 2015.

WGidt - NJC Poster prize 2015Wjatscheslaw Gidt (Ph.D. student working in the group of Prof. Helmut Sitzmann at the Technischen Universität Kaiserslautern, Germany) received the award at the 13th Ferrocene Colloquium (held in Leipzig last winter) for his poster entitled “Synthesis, Structure and Reactivity of the Chromium Complexes [4CpCrX]2 (X = OAc, Cl, I, OTf)”.

His study shows that paramagnetic cyclopentadienylmetal halides of nickel, cobalt and iron, with bulky alkylcyclopentadienyl ligands, are very reactive starting materials for the formation of novel organometallic compounds capable of carbon-carbon bond formation or cleavage.

__________________________________________________________

This summer, at the International Conference on Advanced Inorganic Complex Nanomaterials held in Namur, Belgium, two young scientists were honoured.SoraChoi - NJC Poster prize 2015

Sora Choi (Ph.D. student under the supervision of Prof. Moonhyun Oh at the Yonsei University, Korea) won a poster prize for her work “Structural and Morphological Transformation of Metal-Organic Frameworks via Destruction and Reconstruction Pathways” in which she reports the structural and morphological transformations of three-dimensional Kagome-like structured hexagonal lumps (In-MIL-68, [In(OH)(BDC)]n) with blunted ends, into three-dimensional quartz structured hexagonal rods (QMOF-2, [InH(BDC)2]n) with pointed ends.

CedricMarien - NJC Poster prize 2015

Cédric Marien (Ph.D. student with Didier Robert at the University of Strasbourg, France and the INRS, Canada) received the award for his research that aims to develop TiO2 based nanostructures for the photo(electro)catalytic removal of organic compounds in water. His poster “Removal of organic pollutants by photocatalysis with TiO2 nanotubes” reported TiO2 nanotubes electrochemically grown on titanium foils. The study shows that the photocatalytic activity of the tubes depends on their morphology, particularly on the internal diameter and wall thickness.

__________________________________________________________

The XIII International Symposium on Bioinorganic Chemistry held in Karpacz, Poland, in September, also revealed two young talented chemists.

KSokolowski- NJC Poster prize 2015The award-winning poster of Kamil Sokołowski (postdoctoral researcher at the Institute of Physical Chemistry of the Polish Academy of Sciences in the research group of Prof. Janusz Lewiński), entitled “Bio-inspired fixation of CO2 on organozinc hydoxides: efficient routes to novel nanomaterials based on zinc carbonates”, summarized his Ph.D. project. The presented research demonstrated that carbon dioxide in combination with well-defined organozinc hydroxides of the type [RZnOH]n or [(R)xZny(L)z(OH)n], can be successfully utilized for the formation of novel molecular organozinc carbonates, as well as meso- and microporous materials with unique physicochemical properties. The studies underline the great potential of simple organozinc precursors featuring CO2-reactive Zn–OH groups and proton-reactive Zn–C bonds for the design of new functional materials based on zinc carbonate components.

Joanna_Watly - NJC Poster prize 2015Joanna Wątły (Ph.D. student under the supervision of Prof. Henryk Kozlowski at the University of Wroclaw, Poland) was also recognised for her work, “The Impact of the Cu(II) Coordination on the Structural and Thermodynamic Properties of Poly-His Peptides”, in which she studied the coordination of Cu(II) with (His)6-tag peptide (used in IMAC chromatography) and peptide fragments from snake venoms. The results showed that all studied peptides have a high affinity towards Cu(II) ions. Formation of an α-helical structure induced by metal-ion coordination and the occurrence of polymorphic binding states is very characteristic for these peptides, but the most interesting results were obtained for a snake venom peptide fragment with nine histidine residues. The specific role of these nine His residues in venom is unknown, but this peptide may play a key role in the interaction with metal ions and consequently in the inhibition of the snake metalloproteases.

Congratulations to all five winners !

We wish them continuing success in their research and send them our best wishes for 2016!

Congratulations to the NJC Poster Prize winner at ISXB-1

NJC was pleased to honour Alavi Karim from the University of Gothenburg (Sweden) for her outstanding poster presentation at the 1st International Symposium on Halogen Bonding (ISXB-1) that was held in Porto Cesareo (Italy) on June 18–22.

Alavi Karim is a graduate student in the Department of Chemistry and Molecular Biology where she works under the supervision of Dr. Mate Erdelyi. Her project currently focuses on Understanding Halogen Bonding in Solution.

In her award-winning poster titled “The Nature of [N–Cl–N]+ and [N–F–N]+ Halogen Bonds in Solution” she presented solution-phase NMR spectroscopy data and theoretical studies investigating the geometries and stabilities of the highly reactive, lighter haloniums in comparison to their well-studied iodonium and bromonium centered analogues. Alavi said: “We have characterized three-centre-four-electron halogen bonds, [N–X–N]+, in solution and demonstrated the iodine-, bromine- and chlorine-centred halogen bonds to be static symmetric. In line with fluorine, the [N+–F···N] system shows different behaviour in comparison to the heavier halogens. The complex is asymmetric and thus encompasses one conventional-covalent and one conventional-weak halogen bond. The fluorine- and chlorine-centred systems are highly reactive and could therefore only be stabilized in solution at low temperature. The conclusions drawn from NMR studies were supported by DFT calculations.”

The poster prize committee and winner (from left to right): Giuseppe Resnati, Francesca Baldelli-Bombelli, Alavi Karim and Pierangelo Metrangolo.

Many congratulations to Alavi on receiving her NJC poster prize. She also received a book from the Royal Society of Chemistry and a 1-year electronic subscription to New Journal of Chemistry.
