Sir Richard Brook Sykes FRS FMedSci HonFREng (born 7 August 1942) is a British microbiologist, the chair of the Royal Institution, the UK Stem Cell Foundation, and the trustees at King Edward VII's Hospital, and chancellor of Brunel University. As of June 2021, he is chair of the UK's Vaccine Taskforce, where he is responsible for overseeing the delivery of the COVID-19 vaccination programme, including preparations for booster programmes and encouraging vaccine innovation in the UK.
In 1972, after gaining a first class bachelor's degree and a doctorate, both in microbiology, Sykes was appointed head of the Antibiotic Resistance Unit at Glaxo, where he helped develop the antibiotic ceftazidime. Subsequently, he was recruited by the Squibb Institute, in the United States, where he then developed aztreonam, the first clinically effective monobactam, a term he coined in 1981 to describe a new group of monocyclic β-lactams produced by bacteria. He oversaw the merger of Glaxo with Wellcome, to form Glaxo-Wellcome in 1995 and became its chair two years later. He then oversaw the Glaxo Wellcome and SmithKline Beecham merger and held its chair until 2001.
His other appointments have included being rector of Imperial College from 2001 to 2008, chairman of NHS London from December 2008 to July 2010, vice-chairman of Lonza Group until 2013, and chairman of Imperial College Healthcare from 2012 to 2018.
Richard Sykes was born in the outskirts of Huddersfield, in West Yorkshire, on 7 August 1942 [1] to Eric Sykes and his wife Muriel Mary Sykes. [2] [3] He attended Royds Hall Grammar school. [4] Prior to his A-levels and completing school, he took up a job as a technician in a pathology laboratory. [5] After leaving secondary school he attended Paddington Technical College and Chelsea College, and gained a place at Queen Elizabeth College where he was awarded a first class BSc degree in microbiology. [2] He received his doctorate in 1972 with a thesis on β-lactamases of Pseudomonas aeruginosa , from the University of Bristol, where he worked with Mark Richmond. [2] [6] In 1973, together, they reported the first β-lactamase classification scheme. [7]
In 1972, Sykes was appointed head of the Antibiotic Resistance Unit at Glaxo. [2] [8] There, he helped develop the antibiotic ceftazidime. [9] In 1977 he left Glaxo and was recruited to the United States by the Squibb Institute for Medical Research, where he worked under George B. Mackaness, the Australian immunologist who played an important part in getting the first ACE inhibitor, captopril, licensed. [2] [10] In 1979 Squibb appointed Sykes to lead research into monocyclic β-lactam antibiotics. [2] [9] There, he isolated product SQ26.180 from Chromobacterium violaceum , a bacteria discovered at Pine Barrens. [11] By modifying the amide side chain and including a ceftazidime side chain, he produced aztreonam, the first monocyclic β-lactam antibiotic. [12] [13] In 1981 he coined this new group of antibiotics "monobactam". [9] [12] Its potential as a usefulness was published the following year. [14] It could treat gram-negative infections such as gonorrhoea and became the first monobactam to be licensed for clinical use. [9] [12]
From 1983 to 1986 he was vice-president of infectious and metabolic diseases at Squibb. [2] He returned to Glaxo in 1987 and succeeded David Jack, almost 30 years after Glaxo acquired Allen & Hanburys. [15] The Harvard Business Review noted that at Glaxo, when a group of antibiotics failed in the last stages of clinical trial, Sykes praised the teams that had worked on them and encouraged them to move on. [8] In 1993 he received his DSc. [2]
In 1994, during his time at Glaxo, he was part of the group that founded the Jenner Institute for research into vaccines. [16] [17] [18] In 1995 he oversaw the merger of Glaxo with Wellcome, to form Glaxo-Wellcome. [15] [19] In 1997, he became chair of Glaxo-Wellcome. [20] In 2000 he oversaw the Glaxo Wellcome and SmithKline Beecham merger and held its chair until 2001. [20] [21] [22] The merger resulted in the marketing of several new drugs. [21] According to Sykes at the time, "the industry would be transformed by understanding the human genome". [21]
Sykes was elected a Fellow of the Royal Society (FRS) in 1997. [23] [24] In 1994 he became a trustee of the Natural History Museum, London, [2] and in 1997 he was appointed senior independent director of Rio Tinto plc, a position he held until 2008. [25]
He was a member of the National Committee of Inquiry into Higher Education that published an influential report in 1997.[ clarification needed ] [26]
In January 2001, he was appointed rector of Imperial College London and completed his tenure in 2008. [27] [28] [29] At Imperial, he was involved in several controversial debates including on issues such as increasing tuition fees, which he favoured. [30] He criticised secondary schools for the quality of the science taught there, and opposed teaching grants being awarded on a per capita basis. [28] [31] In 2002 he proposed to merge Imperial College with University College London. [32] [33] The strength of opposition meant that it did not go through. [28] He supported the lifting of the £3,000 cap on tuition fees and instead allowing the universities to set their own fees. [32] [34]
Sykes chairs the UK Stem Cell Foundation. [25] It was established in 2005. [35] [36] [37]
From 2003 to 2005 he was trustee of the Royal Botanic Gardens, Kew. [2] From 2007 to 2011 he was senior independent director and non-executive deputy chairman of Eurasian Natural Resources Corporation. [25] [38] In September 2008, he was appointed chair of NHS London, but resigned in May 2010 over the decision of the Cameron Ministry to halt former health minister Ara Darzi's planned reorganisation of health care in London. [39] [40]
Between 2010 and 2012 he was on the advisory board of the Virgin Group. [25] Until 2013, he was vice-chair at the Swiss life sciences company Lonza AG. [25] [41] He was appointed chairman of the Royal Institution in 2010 and Imperial College Healthcare in 2012. [2] He was appointed Chancellor of Brunel University in 2013. [42] In 2020, Sykes stepped down as chairman of the NetScientific Group after serving it for nine years. [43]
In 2020 he led an independent review of the workings of the Vaccine Taskforce. [44] [45] On 14 June 2021, Sykes was appointed chair of the Vaccine Taskforce, where he will be responsible for overseeing the delivery of the UK's COVID-19 vaccination programme, including preparations for booster programmes and encouraging vaccine innovation in the UK. [44]
Sykes was chairman of the advisory panel of the think-tank Reform. [46] He is a member of the Advisory Council for the Campaign for Science and Engineering. [47] He is chair of the Trustees at King Edward VII's Hospital. [48]
Sykes was knighted in the 1994 New Year Honours. [2] [49]
He holds honorary degrees from several universities including Birmingham, Brunel, Cranfield, Edinburgh, Hertfordshire, Huddersfield, Hull, Leeds, Leicester, Madrid, Newcastle, Nottingham, Sheffield Hallam, Sheffield, Strathclyde, Surrey, Warwick and Westminster. Sykes was elected a Fellow of the Academy of Medical Sciences (FMedSci) in 1998. [50]
In 2009 he received the British Society for Antimicrobial Chemotherapy's Garrod Medal and delivered its accompanying lecture. [51] It was titled "The evolution of antimicrobial resistance: a Darwinian perspective" and was published in the Journal of Antimicrobial Chemotherapy in 2010. [52]
A beta-lactam (β-lactam) ring is a four-membered lactam. A lactam is a cyclic amide, and beta-lactams are named so because the nitrogen atom is attached to the β-carbon atom relative to the carbonyl. The simplest β-lactam possible is 2-azetidinone. β-lactams are significant structural units of medicines as manifested in many β-lactam antibiotics. Up to 1970, most β-lactam research was concerned with the penicillin and cephalosporin groups, but since then, a wide variety of structures have been described.
Beta-lactamases (β-lactamases) are enzymes produced by bacteria that provide multi-resistance to beta-lactam antibiotics such as penicillins, cephalosporins, cephamycins, monobactams and carbapenems (ertapenem), although carbapenems are relatively resistant to beta-lactamase. Beta-lactamase provides antibiotic resistance by breaking the antibiotics' structure. These antibiotics all have a common element in their molecular structure: a four-atom ring known as a beta-lactam (β-lactam) ring. Through hydrolysis, the enzyme lactamase breaks the β-lactam ring open, deactivating the molecule's antibacterial properties.
Penicillins are a group of β-lactam antibiotics originally obtained from Penicillium moulds, principally P. chrysogenum and P. rubens. Most penicillins in clinical use are synthesised by P. chrysogenum using deep tank fermentation and then purified. A number of natural penicillins have been discovered, but only two purified compounds are in clinical use: penicillin G and penicillin V. Penicillins were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci. They are still widely used today for various bacterial infections, though many types of bacteria have developed resistance following extensive use.
β-lactam antibiotics are antibiotics that contain a beta-lactam ring in their chemical structure. This includes penicillin derivatives (penams), cephalosporins and cephamycins (cephems), monobactams, carbapenems and carbacephems. Most β-lactam antibiotics work by inhibiting cell wall biosynthesis in the bacterial organism and are the most widely used group of antibiotics. Until 2003, when measured by sales, more than half of all commercially available antibiotics in use were β-lactam compounds. The first β-lactam antibiotic discovered, penicillin, was isolated from a strain of Penicillium rubens.
Methicillin (USAN), also known as meticillin (INN), is a narrow-spectrum β-lactam antibiotic of the penicillin class.
The cephalosporins are a class of β-lactam antibiotics originally derived from the fungus Acremonium, which was previously known as Cephalosporium.
Meropenem, sold under the brand name Merrem among others, is an intravenous carbapenem antibiotic used to treat a variety of bacterial infections. Some of these include meningitis, intra-abdominal infection, pneumonia, sepsis, and anthrax.
Clavulanic acid is a β-lactam drug that functions as a mechanism-based β-lactamase inhibitor. While not effective by itself as an antibiotic, when combined with penicillin-group antibiotics, it can overcome antibiotic resistance in bacteria that secrete β-lactamase, which otherwise inactivates most penicillins.
Piperacillin is a broad-spectrum β-lactam antibiotic of the ureidopenicillin class. The chemical structure of piperacillin and other ureidopenicillins incorporates a polar side chain that enhances penetration into Gram-negative bacteria and reduces susceptibility to cleavage by Gram-negative beta lactamase enzymes. These properties confer activity against the important hospital pathogen Pseudomonas aeruginosa. Thus piperacillin is sometimes referred to as an "anti-pseudomonal penicillin".
Imipenem is a synthetic β-lactam antibiotic belonging to the carbapenems chemical class. developed by Merck scientists Burton Christensen, William Leanza, and Kenneth Wildonger in the mid-1970s. Carbapenems are highly resistant to the β-lactamase enzymes produced by many multiple drug-resistant Gram-negative bacteria, thus playing a key role in the treatment of infections not readily treated with other antibiotics. It is usually administered through intravenous injection.
Sulbactam is a β-lactamase inhibitor. This drug is given in combination with β-lactam antibiotics to inhibit β-lactamase, an enzyme produced by bacteria that destroys the antibiotics.
Temocillin is a β-lactamase-resistant penicillin introduced by Beecham, marketed by Eumedica Pharmaceuticals as Negaban. It is used primarily for the treatment of multiple drug-resistant, Gram-negative bacteria.
It is a 6-methoxy penicillin; it is also a carboxypenicillin.
Monobactams are bacterially-produced monocyclic β-lactam antibiotics. The β-lactam ring is not fused to another ring, in contrast to most other β-lactams.
Beta-lactamases are a family of enzymes involved in bacterial resistance to beta-lactam antibiotics. In bacterial resistance to beta-lactam antibiotics, the bacteria have beta-lactamase which degrade the beta-lactam rings, rendering the antibiotic ineffective. However, with beta-lactamase inhibitors, these enzymes on the bacteria are inhibited, thus allowing the antibiotic to take effect. Strategies for combating this form of resistance have included the development of new beta-lactam antibiotics that are more resistant to cleavage and the development of the class of enzyme inhibitors called beta-lactamase inhibitors. Although β-lactamase inhibitors have little antibiotic activity of their own, they prevent bacterial degradation of beta-lactam antibiotics and thus extend the range of bacteria the drugs are effective against.
Carumonam (INN) is a monobactam antibiotic. It is very resistant to beta-lactamases, which means that it is more difficult for bacteria to break down using β-lactamase enzymes.
A penem is a type of β-lactam with an unsaturated five-member heterocycle containing a sulfur atom in a pentacyclic ring fused to the β-lactam ring. Penems do not occur naturally; all are synthetic. Related to penems are carbapenems, which have a carbon atom in place of the sulfur atom.
Cephalosporins are a broad class of bactericidal antibiotics that include the β-lactam ring and share a structural similarity and mechanism of action with other β-lactam antibiotics. The cephalosporins have the ability to kill bacteria by inhibiting essential steps in the bacterial cell wall synthesis which in the end results in osmotic lysis and death of the bacterial cell. Cephalosporins are widely used antibiotics because of their clinical efficiency and desirable safety profile.
Avibactam is a non-β-lactam β-lactamase inhibitor developed by Actavis jointly with AstraZeneca. A new drug application for avibactam in combination with ceftazidime was approved by the FDA on February 25, 2015, for treating complicated urinary tract (cUTI) and complicated intra-abdominal infections (cIAI) caused by antibiotic resistant-pathogens, including those caused by multi-drug resistant Gram-negative bacterial pathogens.
