21st RSC/SCI Medicinal Chemistry Symposium. Cambridge/Virtual - September 13-15, 2021

The Royal Chemistry Society/Society of Chemistry Industry (RSC/SCI) Medicinal Chemistry Symposium is a key symposium in the field of medicinal chemistry that takes place every 2 years at the University of Cambridge, U.K., under the auspices of the RSC and the SCI. This year, in its 21st edition, it was run as a hybrid event, simultaneously attended by both in-person and virtual attendees. Its theme was 'Improving Success', and 25 orals and 30 posters were presented. The scientific program covered recent medicinal chemistry achievements in major therapeutic areas, with a few first-time structure disclosure presentations and particular emphasis on emerging early-stage drug discovery and lead optimization strategies, including reports of successful case studies illustrating fragment-based screening and phenotypic target engagement approaches. Applications of artificial intelligence (AI), mass spectrometry and photochemistry in drug design and discovery were also highlighted. This report will cover some of the medicinal chemistry presentations delivered at the meeting.
