The 2020 IUPAC-Richter Prize in Medicinal Chemistry has been awarded to John Macor, PhD, Global Head Integrated Drug Discovery, Sanofi


Dr. Macor received the award in recognition of his outstanding creative contributions in the field of medicinal chemistry research on drugs for the treatment of migraine. John's improvements to the triptan core structure fueled the discovery of an effective drug within the class that displayed superior pharmacokinetics compared to the flagship triptan drug at that time, sumatriptan. John Macor is a co-discoverer of two advanced clinical candidates within a new class of small-molecule anti-migraine drugs, the calcitonin gene-related peptide (CGRP) inhibitors. One of these is currently under approval review by the FDA. John Macor's contributions to drug design and consistent support of medicinal chemistry have earned him this prestigious prize.

The IUPAC-Richter Prize, comprising a plaque and a check for USD 10,000, will be presented at the XXVI EFMC-ISMC International Symposium on Medicinal Chemistry to be held in Basel, Switzerland (September 6 - 10). The plaque will be signed by Professor Christopher M.A. Brett, President of IUPAC, Gábor Orbán, Chief Executive Officer of Gedeon Richter Plc (Budapest, Hungary), and Professor János Fischer, Chair of the IUPAC-Richter Prize selection committee. John Macor will present an acceptance lecture at this Symposium and a second lecture at the 37th ACS National Medicinal Chemistry Symposium to be held in New York (June 28-July 1).


Dr. Macor earned his Ph.D. degree at Princeton University with Professor E.C. Taylor in 1986. His career has spanned four decades and four different pharmaceutical companies. John began his career at Pfizer in 1986 where he was engaged in a variety of CNS drug discovery efforts.  He moved to Astra Arcus in 1994 and focused on cholinergic drug discovery, John then moved to Bristol-Myers Squibb in 1997, where he started in cardiovascular research before transitioning to neuroscience in 2001 and immunoinflammatory research in 2013. In October 2016, he accepted the role as Global Head Integrated Drug Discovery for Sanofi.



IUPAC was formed in 1919 by chemists from industry and academia. For more than 100 years, the Union has succeeded in fostering worldwide communications in the chemical sciences and in uniting academic, industrial and public sector chemistry in a common language. IUPAC is recognized as the world authority on chemical nomenclature, terminology, standardized methods for measurement, atomic weights and many other critically evaluated data. In more recent years, IUPAC has been proactive in establishing a wide range of conferences and projects designed to promote and stimulate modern developments in chemistry, and also to assist in aspects of chemical education and the public understanding of chemistry.  More information about IUPAC and its activities is available at
