Abstract
Two-component signal transduction systems and their expanded variants known as phosphorelays are integral elements of the virulence and antimicrobial resistance responses of a wide range of pathogenic bacteria and fungi and also regulate essential functions. As a consequence, two-component systems and phosphorelays are recognized targets for the development of novel antimicrobial agents and a number of chemically synthesized inhibitors from different chemical classes have been identified by compound library screens. However, in the majority of cases these compounds do not appear to be selective for signal transduction pathways and exert their effect by multiple mechanisms of action. The key to designing molecules to selectively disrupt signal transduction may lie with the conserved features of response regulators and the structural analysis of complexes of signaling proteins.

Chalcogen-modified nucleic acid analogues
Chalcogen-modified nucleosides, nucleotides and oligonucleotides have been of great interest to scientific research for many years. The replacement of oxygen in the nucleobase, sugar or phosphate backbone by chalcogen atoms (sulfur, selenium, tellurium) gives these biomolecules unique properties resulting from their altered physical and chemical properties. The continuing interest in ...read more
