Molecular modelling has become a well-established tool for studying biological mole- cules, moreover with the prospect of being useful for drug development. The thesis summarises research on the methodological advances in the treatment of molecular flexibility and intermolecular interactions. Altogether, seven original publications are accompanied by a text which aims to provide a general introduction to the topic as well as to emphasise some consequences of the computer-aided drug design. The molecular flexibility is tackled by a study of a drug-DNA interaction and also by an investigation of small drug molecules in the context of implicit solvent models. The approaches which neglect the conformational freedom are probed and compared with experiment in order to suggest later, how to cope with such a freedom if in- evitable. The noncovalent interactions involving halogen atoms and their importance for drug development are briefly introduced. Finally, a model for a faithful description of halogen bonds in the framework of molecular mechanics is developed and its per- formance and limits are tested by a comparison with benchmark ab initio calculations and experimental data. 1
