Anthony Pinkerton's Research Focus
Dr. Pinkerton is an experienced medicinal chemist, who leads MedChem efforts for the Prebys Center at SBP. He and his team drive screening hits to chemical probes or through lead optimization. Below are just a couple of examples of programs on which Tony and his team are currently working, or to which they have contributed. With a team of collaborators from Duke University Tony is leading the chemistry effort for the development of a novel series of NTR1 allosteric modulators, the first example of brain penetrant small molecule NTR1 activators that have been described. These first-in-class compounds are being optimized in to possible drug leads for the treatment of schizophrenia, drug abuse, and other neuropsychiatric disorders. In collaboration with Jose Luis Millan, a professor at SBP as well, Tony is leading the development of the first selective, potent and orally bioavailable tissue non specific alkaline phosphatase (TNAP) inhibitors that have shown strong efficacy in a range of animal models of pathological calcification. These inhibitors could have use in a range of disorders including vascular calcification, generalized arterial calcification of infancy (GACI), calciphylaxis and pseudoxanthoma elasticum (PXE). With a group of scientists from both UCSD and the University of Giessen in Germany, the SBP medicinal chemistry team has developed a series of remarkable potent and selective plasmodium falciparum G6PDH inhibitors as a potential treatment for resistant malaria. The lead compounds are currently in animal testing.

Anthony Pinkerton's Bio
Dr. Pinkerton’s career in industry began as a medicinal chemist at the Merck Research Laboratories in San Diego. Over his career, Tony has worked in multiple therapeutic areas including CNS, virology, diabetes, inflammation, and oncology, with extensive experience in GPCRs. He has been both project leader and project manager for oncology, virology and diabetes targets, as well as chemistry lead for the metabolic disease therapeutic area group, in which he helped a team identify and prosecute the most promising new targets in the field.
Tony has also performed due diligence for in-licensing efforts as well as competitive intelligence for multiple targets, in addition to developing IP strategies around multiple chemical series. He has extensive experience with outsourcing chemistry, both discovery and scale up, to China.
Tony is an inventor or co-inventor on over 35 patents or patent applications covering small molecule therapeutics, as well as over 50 publications. During his career he has helped advance multiple compounds into clinical development.
Tony originally trained as a synthetic organic chemist in the laboratories of Dieter Seebach at ETH-Zurich and Barry Trost at Stanford University. He earned his Ph.D. in chemistry from Stanford University in 2001. While at Stanford he developed new metal catalyzed reactions for synthesis and completed the total synthesis of several natural products. He was also a Fulbright Scholar at the Eidgenössische Technische Hochschule (ETH) – Zurich from 1995-1996.
