A major theme of this leukemia SPORE application is translational research that focuses on identifying therapeufically relevant targets for anti-leukemic drug discovery. Each of the projects presented in this application is a testament to a strong collaborative effort between clinicians and basic scientists, which nterfaces many aspects of translational research, including oncogenic signaling, epigenefics, experimental therapeufics, and immunology. The Medicinal Chemistry Core integrates the expertise of two laboratories, including medicinal chemistry, molecular and cell biology, and molecular pharmacology (Chen), and computational chemistry and structural biology (Li). In the past few years, this program has developed a series of agents targeting different molecular defects clinically relevant to leukemogenesis, two of which are ready to enter clinical trials in 2009. Thus, this core provides a platform to translate basic science findings from each of these projects into the design and synthesis of small-molecule agents for tesfing individual hypotheses, and adds an important dimension to expedite the translation from bench to the clinic. Specifically, the following three aims constitute the foci of this Medicinal Chemistry Core with initial emphasis on targefing immunomodulafion in tumor-specific T cells and natural killer cells (Project 3), and protein phosphatase (PP) 2A (Pilot Project 2), which will be expanded to address other new molecular targets arising from other projects. Overall, our specific aims include:
Aim 1. To carry out lead opfimizafion of lenalidomidie to develop specific immunomodulatory drugs for chronic lymphocytic leukemia (CLL) therapy (in collaboration with Project 3).
Aim 2. To carry out structural opfimization of FTY720 to develop novel PP2A-activating agents (in collaboration with Pilot Project 2).
Aim 3. To provide aspects of medicinal chemistry service including custom synthesis, sample preparafions, computational chemistry, and structural biology to interested investigators of this SPORE application (all Projects) and other NCI SPORE and POl investigators. An example of this is providing OSU-HDAC42 to investigators in Projects 4, 5 and Developmental Project 1. Overall, this unique core will provide members of the SPORE a greater opportunity to translate findings into therapeutic opfions for patients with leukemia.
This Core provides support in synthetic medicinal chemistry and structural biology/computational chemistry to individual projects to translate basic science findings into the design and synthesis of small-molecule agents for hypothesis testing. Lead compounds with therapeutic potential will further undergo structural optimization to develop potent agents for clinical translafion.
