Thematik

The complex biochemical equilibria in living bodies as reversible chemical reactions are based on a series of weak molecular interactions. Those interactions are playing very important role in the transfers of such bioactive molecules like the drugs and toxins. Further to this, the weak molecular interactions also play important role in the molecular packing, molecular formulation of medicines. The weak character of these interactions resulted that both the molecular environment and the temperature has high impact on these interactions. The temperature itself affects the efficiency of drugs through affecting the transfer and the drug – target interactions. Therefore detailed description of the temperature dependence of weak interactions is very important also in the associated therapies. Students will become acquainted through several newest research results with the pharmaceutical applications of the processes listed above and with the associated measuring methods and equipments.
