    Sammanfattning : Quantitative structure-activity relationships (OSAR) constitute empirical analogy models connecting chemical structure and biological activity. The analogy approach to QSAR assume that the factors important in the biological system also are contained in chemical model systems.The development of a QSAR can be divided into subproblems:1.

    Sammanfattning : Glutathione transferases (GSTs) play a pivotal role in cellular defense, since they are main contributors to the inactivation of genotoxic compounds of exogenous and endogenous origins. Directed evolution was used to improve the catalytic activities of Theta class GST T1-1 toward different substrates. LÄS MER
