    • Can we have a code for single-stranded nucleic acid recognition?
    • Dr.Neel Sarovar Bhavesh, Transcription Regulation group, International Centre for Genetic Engineering and Biotechnology (ICGEB), New Delhi, India
      Regulation of gene expression in eukaryotes is largely through post-transcriptional modifications of RNA. These modifications include splicing, mRNA polyadenylation, 5’ capping and RNA editing.During his talk, Dr. Neel Sarovar Bhavesh explained how RBPs bind RNA through specific RNA binding domains (RBDs) or modules, and that the binding affinities and specificities vary throughout this family of proteins. In nature, the most widely distributed RBD is the RNA recognition motif (RRM), these RRMs possess a remarkably diverse RNA recognition capability. In this talk Dr. Bhavesh also shared his research team’s recent structural studies on RNA recognition by RRMs. Their studies reveal how a single fold is able to recognize different cognate RNAs by virtue of minor but crucial alterations to its binding surface. In addition, delineation of RNA binding specificities of RRMs has provided molecular clues to the progression of debilitating diseases such asmyotonic dystrophy, FALS and malaria.

        • Tunable Luminescence from Liquid-crystalline Au(I) Complexes
        • Prof. Osamu Tsutsumi, (Department of Applied Chemistry, Ritsumeikan University
          This talk on luminescent materials and their application in light emitting devices by Prof. Osamu Tsutsumi focussed on a phenomenon called aggregation-induced emission (AIE). It has been observed that organic molecules generally have a much-reduced photoluminescence intensity in concentrated solutions or in condensed state due to concentration quenching or aggregation-caused quenching. Some organic molecules, owing to their molecular structure and the structure of their molecular aggregates tend to show high photoluminescence in condensed phase as a result of AIE. Prof. Tsutsumi’s lab has developed liquid-crystalline (LC) luminophores with the AIE property (AIEgen). This lecture reported the luminescent behaviour of LC AIEgen in both solid and LC phases.

        • The Secret of Health is in Gene Expression: Strategies to Regulate Gene Expression to induce Tissue Repair and to Treat Cancer
        • Dr.Oommen P. Varghese, Associate Professor, Translational Chemical Biology Group, Department of Chemistry, Ångström Laboratory, Uppsala University, Sweden
          Genes regulate all cellular processes, therefore, novel strategies that regulate gene expression will allow us to understand and modulate cellular processes. In this meeting, Dr. Oommen Varghese explained how delivering therapeutic proteins such as recombinant human bone morphogenetic protein-2 (rhBMP-2)1-2 could promote stem cell differentiation towards bone, or gene silencing molecules such as short interfering RNA (siRNA) 3 and microRNA (miRNA) could target cancer cells and inhibit their proliferation. To deliver these molecules they exploited hyaluronic acid (HA), a natural polymer present in the space between cells known as the ‘Extracellular Matrix’ that gets chemically modified and forms hydrogels or self-assembled nanocarriers. These HA-based nanocarriers, Dr. Oommen explained, present the first non-cationic delivery system that is stabilized by Van der Waals interactions between the biologics and HA. Since HA is known to target the cellsurface CD44 receptors, expressed in cancer stem cells and adult stem cells, it represents a novel drug delivery strategy for translational medicine.

        • Glycosaminoglycans: A formidable biomaterial for nanomedicine, tissue engineering and modulating the immune response
        • Dr.Oommen P. Oommen, Assistant Professor, Bioengineering and Nanomedicine Lab, Faculty of Medicine and Health Technology, Tampere University, Finland
          Cells communicate, transport biologics and regulate cellular processes through the Extracellular Matrix or ECM polymers present at the interphase between the cells. One such group of ECM polymers are glycosaminoglycans (GAGs) (e.g. hyaluronic acid, chondroitin sulfate, heparin, dermatan sulfate, etc). They are the hydrating molecules that keep the cells intact in tissues and regulate cellular processes.Dr. Oommen’s lab has exploited the intrinsic biological properties of these polymers for engineering immunomodulatory nano materials and bulk hydrogels following a supramolecular synthetic strategy. The nano materials engineered using these ECM polymers mitigate the toxic side effect of chemotherapy. Recently, Dr. Oommen’s research group discovered that nano particles designed using specific ECM polymers were capable of penetrating the impermeable blood-brain barrier and could effectively deliver cytotoxic drugs and biologics to the intact brain, opening a plethora of opportunity for treating diseases of the central nervous system. During this meeting Dr.Oommen presented the latest discoveries from his lab, that of discovering the unique property of hyaluronic acid, (the only non-sulfated glycosaminoglycan present in ECM), to deliver siRNA across cellular barrier resulting in the development of the first anionic transfection method for cancer cells and stem cells that express the HA-receptor CD44. His team has successfully engineered ECM mimetic 3D scaffolds and demonstrated its utility in the regeneration of bone and cardiac tissue.

                  • What Controls Asymmetric Catalysis - Steric Repulsion or Weak Noncovalent Interactions?
                  • Prof. Raghavan B. Sunoj, IIT Bombay
                    The key objective of Prof. Raghavan Sunoj’s research group is to gain molecular insights on the factors responsible for stereo selectivity and to exploit such insights towards ‘in silico’ design of novel asymmetric catalysts. Prof Sunoj’s lab employs ab initio as well as DFT methods to gain insights into carbon-carbon and carbon-heteroatom bond-forming reactions of immediate practical significance. This lecture by Prof. Sunoj was designed to cater to a broad and diverse group of audience and therefore focussed on chemical insights rather than technical details. The presentation dealt with a few contemporary themes in the domain of asymmetric multi-catalytic reactions and interesting interpretations/rationalizations of experimental observations.The talk also provided meaningful guidelines for rational improvements in the design of asymmetric catalysts.

                      Dr. Biju’s lab is involved in the study of various catalytic methods. This presentation focussed on NHC catalysis where they have demonstrated for the first time, the NHC-catalyzed umpolung of imines for the synthesis of 2,3-disubstituted indoles, functionalized quinolines and dihydroquinoxalines. Further, Dr. Biju went on to explain the enantioselective NHC-catalyzed annulation reactions for the synthesis of dihydropyranones, dihydropyridinones, cyclopentenes, pyrazoles, spirocyclohexadienones, tricyclic lactones, tetracyclic indoles etc., where NHC-bound α,β-unsaturated acylazoliums are the key intermediates.

                      • Dr. Ramaswamy Murugavel, IIT Bombay
                        Dr. Ramaswamy Murugavel’s research group has been employing an organic-soluble organophosphate as the building block to assemble polyhedral molecules that resemble many of the secondary building units (SBUs) of zeolite materials. This presentation explained in detail how reaction of this phosphate with a divalent metal such as Zn 2+ in a donor solvent (L) leads to the isolation of tetranuclear metal phosphates [(ArO)PO 3 Zn(L)] whose inorganic core resembles the zeolitic D4R SBU. Dr. Murugavel, in this lecture, disclosed how his lab has also unravelled that it is possible to isolate even larger SBUs through small variations in the reaction conditions. Thus, previously unknown discrete clusters with D6R and D8R SBU like cores (Zn 6 O 18 P 6 and Zn 8 O 24 P 8 cores, respectively) have been isolated by switching the solvent from methanol to acetonitrile and the co-ligand from DMSO to either 4-formylpyridine or 4-cyanopyridine. These compounds find application as molecular magnets, and in phosphorous based perovskites.

                      • Dr. Jyotishman Dasgupta, TIFR, Department of Chemical Sciences, School of Natural Sciences
                        There has been considerable change in photovoltaics in the last decade or so, with organic photovoltaics becoming the preferred choice especially due to their lower processing costs and the large choice of available photoactive material, as opposed to silicon-based solar cells. Dr. Jyotishman Dasgupta, in this presentation, described their research interest in understanding the exciton dynamics in variety of conjugated polymers that form the material basis for organic solar cells. He went on to explain Singlet Fission and the experiments conducted in his lab that have helped identify mechanisms of singlet fission in three classes of chromophores: carotenoids, diketopyrrolopyrroles and pentancenes.

                        • Prof. V. G. Anand, Department of Chemistry, IISER Pune
                          This lecture by Prof. Anand focussed on how antiaromatic systems differ significantly in their reactivity and electronic properties compared to aromatic molecules and how π-extended antiaromatic macrocycles after undergoing reversible redox reactions switch between two different states of conjugation. In between these two states of conjugated macrocycles, there also exists the possibility of (4n+1)π and (4n+3)π states, which would ideally belong to the neutral radical species. Such species were not known until the synthesis of a 25π pentathiophene macrocycle. In this talk, Prof. Anand discussed the synthesis, and the reversible redox properties of few antiaromatic macrocycle, to highlight the electron transfer assisted structural transformations in an antiaromatic macrocycle.

                          • Dr. Jennifer M. Heemstra (Emory University)
                            In this presentation Dr. Heemstra reported that in her lab nucleic acids – DNA and RNA are used for applications in biosensing and biomolecular imaging. She talked about how in one project, they had developed RNA sequences that were capable of recognizing specific small molecule fluorophores, and promoting covalent self-labelling with these fluorophores. These self-labelling ribosomes could be used for imaging of RNA in living cells. They had also demonstrated selective enrichment of inosine-containing RNAs using EndoV for non-covalent capture, which they anticipate will enable the identification of new sites of A-to-I editing in cells.
