Prof. Chattopadhyaya is leading multidisciplinary research at the interface of the frontiers of Chemistry/Structure/Enzymology. His research focuses on (a) design of gene (RNA)-directed therapeutics based on Antisense, Small interfering RNA (siRNA) and micro-RNA, in which the translation of the RNA specific to a gene is selectively inhibited, (b) Physical and structural chemistry of DNA and RNA foldings, (c) design and synthesis of drug against resistant bacteria including hospital infections – MDR and XDR Tuberculosis, Staphylococcus aureus (both methicillin and penicillin resistant), vancomycin resitant Enterococcus and pseudomonas. In these research he employs synthetic organic chemistry of heterocycles and carbohydrates to design mimics to model biological functions and/or the transition state. The major achievements include (a) successful design of new conformationally locked chemically modified nucleo(s)tides, to self-organize oligo-DNA and –RNA molecules to minimize the contribution of entropic energy penalty to the free-energy, (b) to improve the stability and cellular delivery of siRNAs and antisense oligonucleotides; (c) development of new synthetic methodologies for RNA, DNA, and their modified analogs as potential DNA/RNA-directed therapeutics (siRNAs, antisense, triplexing agent, aptamers, etc), including synthetic and physico-chemical aspects of monosaccharide, heterocyclic, and phospholipid, phosphorylating and protecting group chemistry. (d) development of novel active antibiotic lead compounds against multiple drug resistant and extensive drug resistant strains of tuberculosis and hospital pathogens; (e) determination of NMR solution structures of RNA to understand RNA folding-dependent function of non-coding RNAs with emphasis on the role of microRNA, siRNAs and RNA catalyst; (e) elucidation of bioorganic chemical mechanisms using synthetic physical and structural (NMR) chemistry to model transition state or the intermediate of biochemical reactions, such as splicing, RNA catalysis, and RNA-RNA-ligand or RNA-DNA-ligand interactions; (f) development of new chemical tools for RNA, carbohydrate and peptide synthesis to understand molecular details of how structure of molecules dictate function.

Currently active particularly successful research areas and groups/networks, in a national or international perspective led by Prof. Chattopadhyaya
● Strong and fruitful collaboration with the infectious diseases, chemical biology and systems biology groups involved in Linnéa sponsored RNA research Consortium concentrating on “Design and Synthesis of Site-specific Bifunctional Ligands Targeted to RNA hairpin loops depending upon their Stem-Loop-size and Sequence-context” funded by the Swedish Research Council (Natural and Technical Research), “Strategic Funding of Uppsala RNA Research Center (URRC) (VR diary No 349-2006-267). Within this project we design and synthesis unique specific Ruthenium based organometalic compounds as well as metallopeptides that are aimed to bind to the sequence-specific stem-loop motif of pre-micro-RNA structure with a far reaching aim to modulate the biosynthesis, and consequently regulating the cellular function of micro-RNA.
● RNA research which is holding very high international level as recognized by the referees of 2010 VR application (VR diary No 2010-4991). This research is focused on three main goals: 1) specific RNA- and chemically modified RNA- synthesis, 2) structure and conformational determination of RNA and 3) studies of RNA function.
● Prof. Chattopadhyaya has been nominated as a Research Professor by the Dept of Science & Technology, India Gov since 2009. In that capacity, he helps to organize strategic research on biotechnology of CSIR/India in an international perspective.
● Prof. Chattopadhyaya is an honorary professor at Jilin University in China, and nominated honorary professor at Nankai University in China.
● Prof.Chattopadhyaya collaborates and actively helped to organize research with 26 scientists at the Institute of Molecular Medicine at Pune/India to devise therapeutics against resistant infectious diseases.
● He has conceived and demonstrated the concept of Stereoelectronic effects in DNA and RNA and their structural and functional implications, which has found wide applications and acceptance internationally (http://www.boc.uu.se/boc14www/publications/Stereoelectronic_effect.pdf ).
● He has conceived and demonstrated the concept of The Uppsala NMR-window concept to simplify the NMR spectra of large DNA/RNA, which is used worldwide.
● He has conceived and demonstrated the design principles for the synthesis of new conformationally-constrained nucleic acids and their enzymology to develop effective antisense oligos and siRNAs to enhance blood serum stability and facilitate delivery.
● He has conceived and demonstrated the design principles for the Synthesis and modifications of aza-modified conformationally restricted nucleotides as fluorescent DNA probes.
● He has conceived and demonstrated that the single-strand DNA and RNA conformation in the purine-rich single-strand oligo-DNA and –RNA are well pre-organized to helical form - not random coils as it was originally thought. The structure of the self-assembled single-strand oligo-DNA and -RNA is very much reminiscent of their double-stranded counterparts. The set of papers published from Uppsala on self-assembled single-strand oligo-DNA and -RNA has brought about a paradigm shift after Watson-Crick basepaired double helix as the origin of helical structure of DNA duplex
● He and his coworkers have shown that all internucleotidic phosphodiester bonds in RNA are not chemically equivalent, and their reactivity depends upon the sequence-context governed by specific intrinsic electrostatic interactions.
● He and his coworkers have developed solid-phase oligo-RNA synthesis utilizing our new 2'-O-TEM protecting group.
● He and his cowrkers have designed, synthesized, performed biological evaluation and molecular modeling studies of novel quinoline, triazole, urea and thiourea derivatives against drug resistant Mycobacterium tuberculosis.
