1. Pilicides and Curlicides : Design, synthesis, and evaluation of novel antibacterial agents targeting bacterial virulence
Sammanfattning : New strategies are needed to counter the growing problem of bacterial resistance to antibiotics. One such strategy is to design compounds that target bacterial virulence, which could work separately or in concert with conventional bacteriostatic or bactericidal antibiotics. LÄS MER
2. Studies on nucleic acids chemistry
Sammanfattning : This thesis is divided into three parts: Part 1: Synthesis and conformational analysis of cyclic RNAs, and comparison with lariat RNAs modelling the lariat formed during processing of Group II and Nuclear pre-mRNA. Synthesis of a hexameric lariat RNA model with a tetranucleotidyl "2' → 5' loop" and a dinucleotidyl "3'-tail" has been accomplished. LÄS MER
3. Some Aspects of Nucleic Acids Chemistry
Sammanfattning : This thesis is divided into two parts based on a total of 8 papers: Part 1: Synthesis, physicochemical and biochemical studies of chemically modified oligonucleotides and their duplexes and triplexes. Potency of the chromophore conjugated DNA oligonucleotides as antigene and antisense gene repressors was evaluated. LÄS MER
4. Modified Glycopeptides Targeting Rheumatoid Arthritis : Exploring molecular interactions in class II MHC/glycopeptide/T-cell receptor complexes
Sammanfattning : Rheumatoid arthritis (RA) is an autoimmune inflammatory disease that leads to degradation of cartilage and bone mainly in peripheral joints. In collagen-induced arthritis (CIA), a mouse model for RA, activation of autoimmune CD4+ T cells depends on a molecular recognition system where T-cell receptors (TCRs) recognize a complex between the class II MHC Aq protein and CII259-273, a glycopeptide epitope from type II collagen (CII).

5. Development and Evaluation of Tools to Explore Posttranslational HexNAc-Tyrosine and Mucin-Type O-Glycosylation
Sammanfattning : Glycosylation is the most abundant form of post-translational modification (PTM). Recently, O-glycosylation attracted much attention in the glycoproteomic field due to its association with various diseases, such as pathogenic infections and cancer. LÄS MER
