The Drug Discovery Unit, Wellcome Centre for Anti-Infectives Research is a fully integrated, “Biotech-style” drug discovery operation of 130 scientists, with a remit to complement Biotech/Pharma activities by tackling early-stage small molecule drug discovery across a range of therapeutic areas. We have a remit to address unmet medical need for infectious diseases of low- and middle-income countries, including TB, leishmaniasis, Chagas disease, cryptosporidiosis, schistosomiasis and malaria. Our projects and skillsets cover all aspects of early drug discovery, from hit identification, through lead optimisation to candidate selection. Our experienced team, many of whom have a background in Biotech/Pharma, works in a state-of-the-art building with cutting-edge equipment and automation for drug discovery.

Role & Expertise

Our Gates Foundation funded TB drug discovery activities, focus on identifying safe and orally dosed candidates with the greatest potential to contribute to drug regimens that will significantly reduce the duration of TB drug therapy. We work on assets arising from phenotypic screening and target-based projects, focusing on computational and medicinal chemistry, DMPK and target assays; relying on members of the TBDA to carry out all TB biology, from primary screening, mode of action determination to in vivo testing. The DDU works with the NIAID, on a high throughput in vitro method to determine the rate and routes of compound metabolism by TB.

The WCAIR Training Programme aims to support individuals from low-middle income countries working in drug discovery. We provide a range of training options, from short courses (both online and face-to-face), funded training placements in Dundee, to bespoke support for institutions to help develop their skills in drug discovery research. Our training placements in Dundee are designed to support the individual researcher, building upon the skills they have and allowing them to learn new skills and techniques that can be transferred to their own institution. Our team of trainers work with the experts in WCAIR to ensure that individuals gain as much experience as possible during their placement. Where possible, trainees are placed into working drug discovery portfolios to see how the scientists interact in a live project.

We run a number of short courses, some that cover all aspects of running a drug discovery programmes, while others are designed to teach very specific skills or techniques. We work with a number of institutions in different countries to support their own requirements, developing programmes which are suitable for their researchers. We have also developed some online resources which are free to access
