Our group focuses on:
1) Quality and analytics of (anticancer) medicines (small molecules and biologics) for discovery, preclinical investigations, clinical trials and post-approvals (GMP-laboratory).
2) Regulatory affairs, from discovery to market access.
3) Peptides as bioactive molecules (biomarkers, medicines): (bio)analytics, target interaction, pharmacodynamics and pharmacokinetics (receptor, cell, tissue/organ, rodent). Peptides are also involved in cancer, and as such, they can be used as biomarkers but also as theranostics. Two examples from our group highlight the role of peptides in cancer:
- quorum sensing peptides, produced by micro-organisms including our microbiome, have been demonstrated i.a. to promote metastasis. Hence, this group of bacterial molecules is also an explanatory factor in the host-microbiome interaction (e.g .CRC, breast and oral cancers)
- Cryptic peptides, derived from proteins (eg human growth hormone), can be used as novel lead molecules to target cancer cells (e.g. melanoma).
Next to our interest in peptides, we are experienced in establishing quality specifications and analytics of investigational and marketed medicines used in oncology, e.g. asparaginase.
Of note, our team is also involved in the Ghent University Expertise Centre MSsmall (mass spectrometry analysis of small organic molecules), and is a GMP (EU recognized) laboratory for quality evaluation of medicines.
Finally, we have experience in ADME in rodents (incl. BBB study) and transdermal/mucosal diffusion experiments (Franz cells using human skin and porcine oral mucosa).
