Biography
Robert Falconer is a Pharmacist, having obtained his pharmacy degree from The School of Pharmacy, University of London (now UCL School of Pharmacy). He undertook his pre-registration pharmacy training year at Joyce Green Hospital, Dartford, Kent. He then returned to academia in London, where he undertook a PhD in medicinal chemistry (2000). He was subsequently appointed Research & Teaching Fellow, and then Lecturer in Pharmaceutical Sciences.
A move to the new Institute of Cancer Therapeutics (ICT), University of Bradford followed (2005), to establish one of three new medicinal chemistry teams there. He is an academic responsible primarily for research, but also research-informed teaching (primarily the ICT’s post-graduate MSc courses) and the training of research students. His major interests include the cancer cell glycocalyx, and in the development of protease-activated anticancer prodrugs.
He has served as Deputy Director of the ICT since Feb 2017, overseeing medicinal chemistry and drug discovery, and was promoted to Professor of Medicinal Chemistry in 2019. He is a founder of University spin-out company Incanthera plc, leads the ICT's £2m Doctoral Training Centre, and currently co-leads a £1.5m programme grant from Yorkshire Cancer Research. He is a member of several professional and learned societies, notably the Royal Pharmaceutical Society and is a registered pharmacist with the General Pharmaceutical Council. As a Fellow of the Royal Society of Chemistry, he has previously served as Honorary Treasurer for the RSC Central Yorkshire Local Section Trust (2012-18).
Teaching
Teaching interests
Robert's teaching activities are primarily focused on the application of medicinal chemistry to cancer drug discovery, with contributions to several modules across the ICT's MSc and MRes post-graduate courses in Cancer Drug Discovery, Cancer Pharmacology, and Drug Toxicology and Safety Pharmacology. He leads the Principles of Drug Discovery module (INC7014-B), which provides an overview of the various elements of the drug discovery process, from designing molecules, through in vitro screening, drug metabolism and ultimately clinical trials. He contributes to some modules in the MPharm Pharmacy and BSc Clinical Sciences degrees.
He regularly supervises research projects and dissertations for MSc/MRes and undergraduate students, including ERASMUS placement students from overseas partners, and is also a personal academic tutor for students undertaking the Foundation in Clinical Sciences course.
Research
Robert’s interests are primarily focused on the tumour glycocalyx as a therapeutic target, and glycosyltransferases in particular, and in tumour protease-activated drug delivery. He is an experienced principal investigator and has secured funding from research councils and medical charities. He currently holds grants from Breast Cancer Now, Bone Cancer Research Trust, Incanthera plc, and co-leads a major £1.5m Yorkshire Cancer Research programme grant for cancer medicines discovery. He heads a team of 3 post-doctoral research assistants and 5 PhD students. He also leads the newly created Institute of Cancer Therapeutics Doctoral Training Centre (ICT DTC), established in 2019 following a major 10-year investment by Incanthera plc (£2m).
He has a keen interest and track record in knowledge transfer and cancer drug development. As lead medicinal chemist, he is co-founder and technology co-inventor of the ‘crocus smart-bomb’ (MMP-targeted anti-vascular agent ICT2588), which is being progressed to the clinic by Ellipses Pharma/Incanthera Ltd. Incanthera is an ICT/University of Bradford spin-out company (www.incanthera.com). He is co-inventor on four patents associated with this technology.
Current Research Projects
1. Anti-cancer agents targeting the tumour glycocalyx
This research is focused on the design, synthesis and biological evaluation of inhibitors of polysialyltransferase (and prodrugs thereof) as a means by which to modulate tumour cell migration, invasion and metastasis. The polysialyltransferases are responsible for the tumour cell surface biosynthesis of polysialic acid (polySia), which plays a key role in the metastatic process in a number of cancers (see review: Curr. Cancer Drug Targets, 2012, 12, 925-939). We are employing computational methods to aid the inhibitor design process and have the capability to assess enzyme inhibition (see Analyst, 2020, 145. 4512-4521, ), cell-surface polySia decoration (see review: Carbohydrate Polymers, 2019, 224, 11545), and effects on cell-cell and cell-matrix adhesion, cell migration and invasion (see PLoS ONE, 2013, 8, e73366; Scientific Reports, 2016, 6, 33026; ChemBioChem, 2017, 18, 1332-1337). This work is currently supported by Yorkshire Cancer Research (programme grant), and the ICT Doctoral Training Centre.
Current PhD students: Marrwa Ali, Alexandra Serre (ICT DTC)
Current PDRAs: Dr Francis Mprah Barnieh (YCR); Dr Goreti Ribeiro Morais (ICT DTC)
2. Endoprotease-activated therapeutics
This research is focused on the transformation of potent cytotoxic agents to inactive peptide-conjugates that are selectively activated within the tumour microenvironment, and is a strategic partnership with the DMPK group (Prof Paul Loadman) in the ICT. We are currently interested in the matrix metalloproteinases (MMPs) which are a family of endopeptidases overexpressed in tumours. We are employing both solution and solid phase chemistry to synthesise peptide-based therapeutics with potent but selective cytotoxicity in vivo. Compounds are assessed for in vitro cytotoxicity, successful cleavage in tumour tissue, stability in normal tissues (liver, kidney, lung) and plasma, before being evaluated in vivo (key collaboration with Dr Steve Shnyder, ICT). Our lead compound ICT2588 is currently progressing towards a Phase I clinical trial with Ellipses Pharma, having been licenced by Incanthera plc (see Cancer Research, 2010, 70, 6902-6912; Molecular Pharmaceutics, 2014, 11, 1294−1300).
We are also collaborating with the Daldrup-Link group (Standford University, USA) to develop a novel theranostic, which has shown efficacy in breast cancer (see Small, 2014, 10, 566-575) and glioblastoma (see Molecular Cancer Therapeutics, 2017, 16, 1909-1921 and Nanotheranostics, 2019, 3, 299-310). Current projects are focused on development of treatments for breast cancer, prostate cancer and osteosarcoma. Our research is currently funded by Breast Cancer Now, Bone Cancer Research Trust, and the ICT Doctoral Training Centre.
