Topics of research:

We design, synthesize and characterize pharmacologically novel receptor ligands for diagnostic and therapeutic applications in the fields of cancer, inflammation and neuropathic pain.

  • Development of ligands targeting purinergic receptors: P2X4R, P2X7R, P2Y1R, P1 receptors
  • HCN channel ligands
  • CD73 inhibitors
  • Development of antitrypasomal agents
  • Imaging probes
  • Targeted drug-delivery
  • Nucleoside/Nucleotide chemistry
  • Bioisosteric replacements is drug design

Chembion project description:


Hyperpolarization-activated cyclic nucleotide-gated cation (HCN) channels play a key role in the regulation of cardiac and neuronal rhythmicity. An HCN subunit is comprised of six α-helices (S1–S6) and a loop domain between the S5 and S6 helix that forms the ion selectivity filter and the positively charged S4 helix functioning as a voltage sensor. The cyclic nucleotide-binding domain (CNBD) is connected to the channel core (S6 helix) via the C-linker. cAMP binding to CNBD leads to induction of a rightward shift in the voltage-dependence of activation. The molecular structure of the CNBD in complex with cAMP was resolved for all four channel subtypes.
HCN channels were shown to be valuable targets for the treatment of stable angina pectoris, neuropathic pain and epilepsy. However, the lack of subtype-selective
