John A. Beutler, Ph.D.
Associate Scientist
Molecular Targets Program
Head, Chemical Diversity Development Section

Dr. Beutler has identified several natural products which have potential for development as cancer drugs, among them, englerins, which are in preclinical development for kidney cancer and Ewing’s sarcoma, schweinfurthins, which are preclinical candidates in glioblastoma and malignant peripheral nerve sheath tumors, and salicylihalamides, of interest in sarcomas. As a Staff Scientist 2, Dr. Beutler oversees the Program's high-throughput screening libraries, information technology, and drug development efforts.

Areas of Expertise

1) natural products chemistry, 2) high-throughput screening, 3) molecular pharmacology

We are advancing two natural product projects towards the clinic: englerins for kidney cancer and Ewings sarcoma, and schweinfurthins for central nervous system (CNS) tumors and other NF1-dependent conditions. These natural products both have unique mechanisms of action.  In addition, our group builds and maintains the library of chemical diversity with which the Molecular Targets Program conducts high-throughput screening campaigns based on CCR-identified molecular targets.
