The birth of the IOI

The Ineos Oxford Institute for Antimicrobial Research (IOI) was established at the University of Oxford in January 2021 to rapidly advance research, education and collaboration in search of solutions to tackle the growing threat of antimicrobial resistance.

The IOI was established at the birthplace of penicillin development, thanks to a £100 million donation from INEOS.

INEOS, one of the world’s largest manufacturing companies, and the University of Oxford, one of the world's leading academic institutions, launched a new world-leading institute to combat the growing global issue of antimicrobial resistance (AMR), which currently causes an estimated 1.27 million excess deaths each year- and could cause over 10 million deaths per year by 2050.

Oxford and the history of antibiotics

The history of antibiotic development is inextricably tied to Oxford University and the culture of British innovation within its faculties- which includes the most recent and well-known development of an effective Covid-19 vaccine, and promising progress on tackling malaria.

1928

The story of Penicillin began with Alexander Fleming, at St Mary’s Hospital, London in 1928. Fleming discovered that the mould Penicillium notatum produces a substance that kills bacteria.

1945-1947

The enormous demand for Penicillin generated by World War II was a key reason for the rapid increase in its global production. By the end of 1945, there were 8 British companies - including the chemical manufacturer ICI and the pharmacist Boots, along with the Royal Navy - producing Penicillin in 12 different UK factories. In the US, Pfizer quickly became the world’s largest producer of Penicillin. In the second half of the 1940s, the use of Penicillin surged across Europe. Post-war, the newly founded World Health Organization (WHO) built its own penicillin factories to make the drug globally available.

1948

Antibiotic discovery drives through the 1940s and 1950s were massively successful. Penicillin was quickly augmented by several other classes of effective antibiotics- including cephalosporins which have become the largest class/sub-class of drugs used in clinical medicine. In 1948, Giuseppe Brotzu found that Cephalosporium acremonium produced antimicrobial properties like Penicillium spp. He subsequently worked with the Oxford team of Sir Edward Abraham and Guy Newton who characterised the compound, Cephalosporin C. Oxford Nobel Prize winner Dorothy Hodgkin defined the structure of Cephalosporin C and of Penicillin, using X-ray crystallography.

1950s-1960s

In his 1945 Nobel Prize lecture, Alexander Fleming spoke of the dangers of antibiotic ‘underdosage’ and warned that common bacteria could evolve to become resistant to the new wonder drugs- a phenomenon which indeed did quickly develop. Within a decade of the discovery and mass production of antibiotics, their low cost and widespread use (including in livestock) led to a number of antibiotic-resistant bacteria strains spreading among humans and animal populations around the globe - a process which is still ongoing.

1970s-1980s

While pharmaceutical companies developed several additional antibiotics from the 1960s to the 1980s, the recommended use of new drugs for infrequent and short course treatments made them far less lucrative. This lead to pharmaceutical companies changing their focus from discovery and development of new antibiotics to other drugs that are taken regularly and for prolonged periods.

1990s-present

Since the 1990s, pharmaceutical business models have shifted to more profitable drugs. Consequently, breakthrough antibiotics have failed to emerge to tackle the increasingly number of antibiotic-resistant pathogens. A few notable exceptions to this trend have been the discovery and development of Bedaquiline and Cefiderocol.

2021

The IOI was created in January 2021 to help rejuvenate antimicrobial research, investing in the core science underpinning drug discovery to enable the search of solutions to tackle the growing threat of antimicrobial resistance.
