Designing new molecules against Alzheimer’s disease using artificial intelligence techniques


About This PhD Project

Project Description

The Sheffield Chemoinformatics Research Group is pleased to offer a fully-funded 3.5 year PhD studentship. The student will be based at the University of Sheffield’s Information School (ranked best in UK and Europe in its field by the QS University ranking 2019) and will collaborate closely with Professor Beining Chen’s Medicinal Chemistry group in the Department of Chemistry.

Project description
Alzheimer’s disease (AD) is the most common type of dementia in the UK. According to the Alzheimer’s society, the number of people with dementia in the UK is expected to reach 1 million by 2025. There is currently no cure for AD and clinical trials of drug candidates have been unsuccessful, so there is still a large unmet need for a treatment against AD.

Artificial intelligence techniques, such as generative models, have become very popular in pharmaceutical research. Generative models are machine learning tools that can design novel molecules. These techniques hold great promise as an alternative to traditional techniques, where molecules are built up from small fragments. Recent research has shown that generative models can be trained to produce molecules active against a specific protein. The main aim of the PhD is to explore the possibility of training models that generate molecules active against more than one protein. Molecules with activities against several proteins are ideal drug candidates for complex diseases such as AD, where different cellular pathways are affected.

In this PhD, the successful applicant will focus on investigating how the knowledge of different biological activities is learnt and transferred when training generative models. They will test different strategies to explore under what conditions are generated molecules are active against desired proteins, with a focus on proteins known to be involved in the progression of AD.
