Parke-Davis Pharmaceutical Research Division, Ann Arbor, MI, 1992 - 2000
Director of Diabetes Chemistry
- Began start-up of the chemistry group to support our diabetes project.
- Searched for novel agents in the diabetes and obesity area with a team of sixteen chemists.
- As the Project Co-coordinator, Project Leader and a member of the joint Research Council for the Parke-avis/Ligand Pharmaceutical initiated collaboration to find novel estrogenic agents.
- As member of the Research Management Committee in the Parke-Davis/Allergan Inc. joint venture identified novel retinoids with anti-diabetic activity.
Associate Research Fellow
- Became a part of the anti-cancer project, using the latest advances in signal transduction to find original, mechanism based therapies.
Research Fellow
- Following promotion began designing and synthesizing very potent and specific tyrosine kinase inhibitors, culminating in low picomolar inhibitors of the EGFR tyrosine kinase, an improvement of 105 in potency over our original leads.
- Demonstrated that selective potent inhibitors of tyrosine kinases could be obtained, and at the highly conserved ATP-binding site.
- Developed very selective, irreversible, inhibitors of the ErbB family of RTKs from our original leads, and was heavily involved in the discovery and development of CI-1033, first clinical candidate.
- Participated with biology staff in getting new targets screened, and in coordinating strategy for both in vitro and in vivo screening.
- Identified and defined leads from kinase random screens.
- Sole identifier in the selective MEK inhibitor PD 098059 from random screening.
- As Chairman of the MAP kinase working group, developed selective, nanomolar potency, nanomolar inhibitors for the enzyme MEK, including two clinical candidates CI-1040 and PD 0325901.
Senior Scientist, 1984 - 1988
- Chemical coordination for antipsychotic evaluation in the Adenosine Receptors project.
- Lead chemist on the synthesis of the first potent, highly selective, adenosine A2a receptor agonist, in a project involving innovative use of molecular modeling.
- Began working on quinolones in the Anti-infective project, and was promoted to Research Associate.
- Developed innovative techniques for novel quinolone synthesis, including developing chemistry to exploit the ability of aryl fluorides to direct ortho-lithiation.
- Gained considerable experience interacting with both biochemists and pharmacologists, and at picking compounds for both primary and secondary screening for efficacy and liabilities.
