Bioinorganic Chemistry Workshop on Drug Discovery Heads to Ioannina
The Workshop on Bioinorganic Chemistry in Drug Discovery forms one of the flagship sessions of the 16th International Symposium on Applied Bioinorganic Chemistry in Ioannina. Held at the University of Ioannina in June 2023, the workshop gathers researchers across the Mediterranean rim to explore how metal-based compounds can be designed, screened, and translated into clinical candidates. The program pairs invited speakers with short talks drawn from the broader symposium community, with hands-on engagement built into every themed block.
For attendees arriving from the Southern Hemisphere, the workshop offers a rare chance to engage European collaborators during what would be the Australian winter. Researchers from the Parkville precinct around the University of Melbourne, the Peter MacCallum Cancer Centre, and Monash University's Institute of Pharmaceutical Sciences have historically been active ISABC contributors. Their travel to Ioannina reflects the global pull of bioinorganic chemistry at a moment when platinum, ruthenium, and gold complexes are re-entering clinical pipelines.
Designing Metallodrugs for Unmet Therapeutic Needs
The opening block turns to the strategic side of drug discovery: how do chemists decide which metal centres, ligands, and oxidation states to prioritise when a disease target remains poorly served by organic molecules? Speakers outline case studies spanning anticancer platinum derivatives, photoactivatable ruthenium scaffolds, and antimicrobial silver compounds that exploit bacterial membrane disruption. Each case shows how a careful choice of coordination geometry can deliver selectivity that purely organic leads struggle to match.
Discussions also touch on neglected indications that resonate with Australian research priorities, including tropical parasitic infections and antimicrobial resistance in remote communities. Groups at the University of Queensland's Australian Institute for Bioengineering and Nanotechnology have published on metal-based antimalarials and metallo-antibiotics, providing a natural entry point for joint sessions with Greek and Italian colleagues.
From Bench to Preclinical Models
A second block moves from molecular design into biological validation, with talks organised around cellular uptake, redox cycling, and target engagement. Researchers from CSIRO's biomedical programs and the Harry Perkins Institute in Perth have developed mass spectrometry workflows for tracking metal species inside cells, and these feature alongside European contributions on synchrotron-based imaging.
The session also explores how Australian pragmatism, often summed up by the phrase "have a go", mirrors the iterative bench-to-bench culture of preclinical drug screening. Early-career researchers are encouraged to share negative results and methodological pivots, a hallmark of the Australasian medicinal chemistry community that values persistence over polished narratives.
Computational Tools and Machine Learning
Computational bioinorganic chemistry has matured rapidly, and the workshop dedicates a full block to in silico screening, density functional theory calculations, and structure-activity modelling. Sessions cover open-source docking suites that handle metal centres poorly served by standard force fields, along with machine-learning models trained on curated metallodrug libraries.
Australian groups are well represented here, with the National Computational Infrastructure in Canberra offering high-throughput queues and University of Sydney teams contributing open datasets. The block closes with a panel on how AI-driven pipelines can be validated against experimental observables without overfitting to limited metal-coordination training sets.
Industry Partnerships and Translation
The penultimate block turns toward the regulatory and commercial landscape that determines whether a promising compound reaches patients. Representatives from Australian biotech firms with metallodrug pipelines, including Telix Pharmaceuticals and specialty firms around the Sydney Biomedical Accelerator precinct, share lessons on chemistry, manufacturing, and controls documentation and GMP scale-up. These discussions resonate with European presenters facing similar hurdles under EMA oversight.
Funding pathways receive attention too, with NHMRC development grants and ARC Linkage projects offering models for academic-industry collaboration. Speakers contrast these with European instruments such as EIC Pathfinder grants, helping researchers position themselves for cross-jurisdictional partnerships and joint funding applications.
Practical Logistics and Registration
The workshop is structured as a two-day intensive running alongside the main ISABC programme. Plenary lectures take place in the main Ioannina congress hall, with breakout sessions and poster clusters hosted in adjacent seminar rooms. Coffee breaks follow Greek custom, stretching into the late afternoon, and the evening mixer offers local Epirus wines and meze alongside scientific discussion.
Delegates should consult the symposium schedule to plan attendance around keynote sessions and travel windows. The Zita Congress & Event Management team assists with abstract submission deadlines, accommodation blocks, and visa invitation letters for Australian researchers who need to demonstrate ties to the University of Ioannina. Early-career applicants should note that the Young Scientist Travel Awards and the Best Poster Prize provide meaningful financial support.
Comparing Metallodrug Strategies
The workshop's reference materials include a side-by-side comparison of major metallodrug strategies, designed to help delegates choose which poster clusters to prioritise. The table distils the current clinical maturity of each metal class, alongside representative elements and the therapeutic indications where they show the most promise. Participants often use it to plan their movement between parallel sessions, especially when travel between rooms takes longer than expected.
| Strategy | Representative Metals | Key Therapeutic Areas | Typical Development Stage |
|---|---|---|---|
| Classical coordination complexes | Platinum, palladium | Oncology | Approved drugs, generic erosion |
| Photoactivatable scaffolds | Ruthenium, iridium | Dermatology, oncology | Preclinical and Phase I |
| Redox-active antimicrobials | Silver, copper | Wound care, AMR | Approved devices, combinations |
| Diagnostic radiometallics | Technetium, gallium | Imaging, theranostics | Approved diagnostics |
| Metal-organic frameworks | Zinc, iron, zirconium | Targeted delivery | Early preclinical |
This quick reference helps workshop attendees weigh which metal class to discuss during the poster sessions.
Book your travel early and pair the workshop with at least one day in the surrounding Epirus region, where Lake Pamvotis and traditional stone villages provide a memorable backdrop for informal conversations. Many delegates find that the strongest collaborations emerge during these unscripted hours, often over shared meals at family-run tavernas. If you are presenting a poster or short talk, prepare a one-sentence summary of your work that you can deliver confidently after a long flight. Australian researchers are known for cutting straight to the chase, a quality that pairs well with the workshop's emphasis on translational impact. Reach out to the secretariat through the Zita portal if you need assistance with registration or accommodation, and secure your spot for the Young Scientist Travel Award if you are within ten years of your PhD.
