Smart nanomaterials as novel anti-cancer drug delivery systems.

Lead Research Organisation: University of Bristol
Department Name: Chemistry

Abstract

The project aims to develop a novel class of targeted drug delivery systems to improve the selectivity and delivery of cytotoxic drugs towards specific cell lines.

Functional nanomaterials will be prepared combining specific targeting motifs and anticancer drugs. The new pro-drug conjugates will be tested as selective G-quadruplex binders as an anticancer target using several techniques including qPCR, UV, Fluorescence, CD, NMR and molecular modelling (in Bristol and with Dr. Morales (CSIC in Granada)).

In parallel, the pro-drug conjugates will be tested in vitro with our commercial cancer cell lines and will be screened for intracellular uptake, selectivity towards disease cell lines, specific intracellular localization as well as drug delivery rate using confocal microscopy and Fluorescence resonance energy transfer (FRET) studies.

Planned Impact

The students will be the key beneficiaries of this research as they will be exposed to and be able to exploit a new form of
PhD training in the chemical sciences. In particular they will be able to input to and shape their project before embarking on
it - this will make a key impact on the science compared to the normal PhD route and will produce students who are
motivated and engaged from the start. Aspects of the course such as Brainstorming, regular problem sessions, Outreach
and Public Engagement, and the organization and delivery of the CDT-Syngenta Award to a world-leading academic will
produce students who are more confident in their own abilities. This in turn will have a real impact on their future careers
when making presentations or when interviewed, as well as fast tracking their leadership skills. Other aspects of the
training such as IP, Entrepreneurship and Commercialisation, will help stimulate and prepare these students for developing
their own Start-up ventures based around their science skills. Science and Technology SMEs are increasingly vital to the
UK's economy and if we are to make an impact on the world stage our next generation of scientists must be empowered to
move quickly and flexibly in that direction. At an academic level the science that these students will produce will make an
impact right across the chemical synthesis landscape and will train a new generation of academic unafraid to cross
chemical boundaries. These students promise to contribute to vitally important areas of society such as healthcare,
medicine, energy and food production - all requiring new molecular entities to be produced efficiently and effectively. The
nations health both financially (eg GDP) and physically (eg antibiotics) desperately need innovative new directions. For
example, the Pharmaceutical industry requires a new direction for drug discovery. One ripe area is to explore new 3D
molecular space, a space that just a few years ago would have been avoided due to complexity and expense. If new drug
IP is to be created, and tax revenue thereof, then we must train a new generation of molecule makers who are unafraid to
take on the challenges of this unexplored space and, more importantly, be able to exploit it commercially. We believe that
our Centre will be able to train PhD students with this level of scientific skill and commercial aspiration.
Our industrial stakeholders are invaluable to the the patronage and direction of the Centre and will benefit greatly from
direct interaction with the various cohorts during their tenure in the Centre. For example, by providing the CDT students
with industrial placements, an effective two way knowledge and skills exchange will operate: students will get invaluable
insight into small, medium and large industries; industry will see first hand the highly motivated and skilled students the
Centre produces as well as get access to much of the unique electronic teaching material that the Centre has developed.
Finally the CDT will have a positive impact on supervisor behavior by ensuring collaboration under conditions that are not
forced or artificial. All potential PhD projects submitted for Brainstorming must have at least two supervisors. This can be
either academic -academic (home/away) or academic-industrial. We have found with the current CDT that these proposals
must describe real collaborations or the students are unlikely to select them. This provides the right encouragement for
collaborators to generate strong proposals that will interest all parties, which in turn is leading to high quality publications in
high impact journals.

Results and Impact Industrial partners of the EPSRC BCS CDT attended a 2 day conference at the University of Bristol in 2018 and 2019. As part of this conference in 2018 I carried out a presentation discussing my PhD project and future plans. In 2019 I presented a poster based on work carried out during my PhD.

Results and Impact Varying numbers of students (ranging from 10-60 on each occasion) across years 9-13 (ages 13-18) from multiple different schools across the UK and Malta attended the University of Bristol on many different dates from 2018-present to take part in Bristol ChemLabs outreach activities. Part of their day involved them listening to a 30 minute talk about my journey into a PhD and about the chemistry involved in my PhD project. The purpose of this activity was to inspire students to study STEM subjects, specifically chemistry, in further education, and to educate students on what PhDs actually are, and to help them relate some of the science they learn at school to the science involved in my PhD, such as carbohydrate chemistry and nanoparticles. This sparked interest and discussion with the students. This talk has been carried out 16 times from november 2018-january 2020 and altered depending on the age group of the audience.

Results and Impact Richard Huish College hosted a Chemistry conference presented by Bristol ChemLabs and funded by the Royal Society of Chemistry Bristol and District, for Year 10 and 11 students from across local secondary schools as well as Huish students currently studying A Level Chemistry. Students from Kingsmead School, Court Fields School, Sidcott School, Shapwick School and The Taunton Academy all attended (approx 100 students). As part of the conference I presented a talk about my academic background, what a PhD is, and spoke about my PhD project and some of the chemistry related to this.

Results and Impact A couple of Bristol PhD students visited an FE college in Ebbw Vale to talk to A-level students during their STEM club. I presented a talk about my academic background, what a PhD is, and spoke about my PhD project and some of the chemistry related to this. There was then a Q&A where we had a discussion with students and offered advice about University.
