Jáchym Hrušák, a student from the Charles University joins our group to work on his Bachelor thesis.
Welcome and good luck!
High school student Klára Wildmannová from Brno joins the group for a 6-week internship to get her first hands-on experience in laboratory work.
Welcome!
Our new work on the synthesis of TCO and BCN containing peptides and their application in bioorthogonal labeling was just accepted in Chemistry—A European Journal.

Congratulation to all authors and big thanks to Agustina who made the great job during her postdoctoral stay in the group!
Ing. Simona Bellová who studied at UCT Prague joins the group as a research assistant.
Welcome!
Adrien Merviel, a student from the National Graduate School of Chemistry in Montpellier (ENSCM) France, joins the group for 4-month internship.
Welcome!
Many drug targets are located in particular cellular compartments known as organelles. Traditional medicinal chemistry approaches focus on bioavailability and tissue targeting, but rarely address drug delivery to specific cellular organelles. Our team has demonstrated that the delivery and release of biologically active molecules from inactive precursors can be achieved in an organelle-specific manner.

Thanks to Francesca for a great job during her internship in the lab!
In our work published as a hot paper within “The Young Chemists 2020 Special Collection” of Chemistry, we describe the influence of various substituents on the photophysical properties of dyes formed in reaction of coumarin-tetrazines with two different dienophiles. These highly fluorogenic reactions can be used for various bioimaging applications in live cells.

In collaboration with the group of Sabine Schneider at LMU Munich, we present in this paper an optimized expression system for production of norbornene-containing single chain antibody. The antibody containing the unnatural amino acid is fully functional and can be used for the attachment of other useful functional groups by click chemistry.
