Abstract:

The laboratory of Toxicology and Pharmacology consists of two main research fields:

Forensic Toxicology;

Drug Discovery and Pharmacology.

The research objectives of Forensic Toxicology are focused on optimisation of analytical detection methods/tools and volatile decomposition detection. The main practice of this subdivision is its service in juridical dossiers as expertise and investigation center at the request of the Ministry of Justice. The research objectives of Drug Discovery and Pharmacology are mainly focused on investigation of venom from venomous animals such as spiders, sea-anemones, cone snails, scorpions, cnidaria, etc. Because these venom peptides regularly work on ion channels of the human body, they are interesting lead compounds for the development of for example analgetics, anti-cancer drugs, drugs for neurological disorders such as multiple sclerosis, Parkinson's disease, Alzheimer's disease, etc.
