Bruce Roth

Last updated

Bruce D. Roth is an American organic and medicinal chemist who trained at Saint Joseph's College, Iowa State University and the University of Rochester, and, at the age of 32, discovered atorvastatin, the statin-class drug sold as Lipitor that would become the largest-selling drug in pharmaceutical history (as of 2003). His honours include being named a 2008 Hero of Chemistry by the American Chemical Society, and being chosen as the Perkin Medal awardee, the highest honour given in the U.S. chemical industry, by the Society of Chemical Industry, American section in 2013.

Early life and education

Roth received his undergraduate degree in chemistry from Saint Joseph's College, Philadelphia, in 1976. [1] He then went to Iowa State University as a doctoral student under George Kraus, receiving his Ph.D. in organic chemistry in 1981. [1] He then spent a year as a Postdoctoral Fellow with A.S. Kende at the University of Rochester.[ citation needed ] [2]

Career

Roth has held a number of positions in his career, from "Scientist" (medicinal chemist) through to vice president-level positions in drug discovery, and his accomplishments in his career include the discovery of the molecule atorvastatin, which would become the drug Lipitor.[ citation needed ]

Positions

In 1982, 28-year-old Roth began work as a medicinal chemist for the Parke Davis research area of Warner-Lambert, [2] [3] becoming the chemistry co-chair of the statins effort, with biologist Roger Newton, in 1984. [2] By 1985, he was at Warner-Lambert's Parke-Davis Pharmaceutical Research facility in Ann Arbor, Michigan. [4] He was promoted to Research Associate in 1986, Senior Research Associate in 1988, Section Director in 1990, Director of Atherosclerosis and Exploratory Chemistry in 1992, and Senior Director of Atherosclerosis, Inflammation and Exploratory Chemistry in 1993.[ citation needed ]By the early 1990s he held managerial positions and was no longer doing laboratory work. [5] :98 In 2000 Warner-Lambert acquired Parke-Davis. He was appointed Vice President of Chemistry just prior to the merger between Warner-Lambert and Pfizer in 2000 and remained in that role as a part of Pfizer Global Research and Development in Ann Arbor, Michigan until 2007. [5] He then joined Genentech in San Francisco, California as Vice President of Discovery Chemistry. [6]

Atorvastatin

Before atorvastatin, Roth worked to develop a different drug, but Sandoz AG beat his team to a patent.[ clarification needed ] [4] In 1985, while working at Warner-Lambert's Parke-Davis research facility, Roth "identified a molecule" that inhibited HMG CoA reductase, a "key enzyme in the metabolic pathway the body uses to produce cholesterol." [7]

Roth was listed as the inventor of trans-6-[2-(3- or 4-carboxamido-substituted pyrrol-1-yl)alkyl]-4-hydroxypyran-2-one, patented in 1986, and developed into the on-market drug, atorvastatin, which ultimately would be sold as Lipitor, [2] [8] [9] [10] and which would become the largest-selling drug in pharmaceutical history by 2003. [3] Pfizer acquired Warner-Lambert and Lipitor in 2000. [3] [11] [12]

Other activities

From 1996 until 2007, Roth served as an adjunct professor in the Department of Medicinal Chemistry at the University of Michigan. [13]

Awards and honours

For the discovery of atorvastatin, Roth received the 1997 Warner-Lambert Chairman's Distinguished Scientific Achievement Award, [5] the 1999 Inventor of the Year Award from the New York Intellectual Property Law Association,[ citation needed ] the 2003 American Chemical Society Award for Creative Invention, [14] [ better source needed ] the 2003 Gustavus John Esselen Award for Chemistry in the Public Service, [5] the 2005 Iowa State University Distinguished Alumni Award,[ citation needed ] and the 2006 Pfizer Global Research and Development Achievement Award.[ citation needed ][ citation needed ] Roth was named a 2008 Hero of Chemistry by the American Chemical Society. [7] [15] In 2013, he was chosen as the Perkin Medal awardee, the highest honour given in the U.S. chemical industry, by the Society of Chemical Industry, American section, for his innovation in applied chemistry that resulted in the outstanding commercial success of atorvastatin. [1] [ citation needed ]

Representative publications

According to the Chemical Heritage Foundation, in "addition to his discovery of atorvastatin, Roth is the inventor or co-inventor of 42 patents and the author or co-author of 48 manuscripts, 35 published abstracts and eight book chapters." [16]

His publications include:

<span class="mw-page-title-main">Cerivastatin</span> Chemical compound

Cerivastatin is a synthetic member of the class of statins used to lower cholesterol and prevent cardiovascular disease. It was marketed by the pharmaceutical company Bayer A.G. in the late 1990s, competing with Pfizer's highly successful atorvastatin (Lipitor). Cerivastatin was voluntarily withdrawn from the market worldwide in 2001, due to reports of fatal rhabdomyolysis.

<span class="mw-page-title-main">HMG-CoA reductase</span> Mammalian protein found in Homo sapiens

HMG-CoA reductase is the rate-controlling enzyme of the mevalonate pathway, the metabolic pathway that produces cholesterol and other isoprenoids. HMGCR catalyzes the conversion of HMG-CoA to mevalonic acid, a necessary step in the biosynthesis of cholesterol. Normally in mammalian cells this enzyme is competitively suppressed so that its effect is controlled. This enzyme is the target of the widely available cholesterol-lowering drugs known collectively as the statins, which help treat dyslipidemia.

In stereochemistry, a chiral auxiliary is a stereogenic group or unit that is temporarily incorporated into an organic compound in order to control the stereochemical outcome of the synthesis. The chirality present in the auxiliary can bias the stereoselectivity of one or more subsequent reactions. The auxiliary can then be typically recovered for future use.

Lanosterol synthase (EC 5.4.99.7) is an oxidosqualene cyclase (OSC) enzyme that converts (S)-2,3-oxidosqualene to a protosterol cation and finally to lanosterol. Lanosterol is a key four-ringed intermediate in cholesterol biosynthesis. In humans, lanosterol synthase is encoded by the LSS gene.

The discovery of HMG-CoA (3-hydroxy-3-methylglutaryl-CoA) reductase inhibitors, called statins, was a breakthrough in the prevention of hypercholesterolemia and related diseases. Hypercholesterolemia is considered to be one of the major risk factors for atherosclerosis which often leads to cardiovascular, cerebrovascular and peripheral vascular diseases. The statins inhibit cholesterol synthesis in the body and that leads to reduction in blood cholesterol levels, which is thought to reduce the risk of atherosclerosis and diseases caused by it.
