Genome Information Research

Dr. Victor J. Hruby is a Regents Professor in the Department of Chemistry and Biochemistry at the University of Arizona. He received his PhD at Cornell University in Theoretical Organic Chemistry and did a Postdoctoral studies with Nobel Laureate Vincent du Vigneaud. He has been a professor at University of Arizona since 1968 where he has joint appointments in the Neuroscience Program, Medical Pharmacology, and Bio5 among others. Dr. Hruby’s research interests are in the chemistry, biophysics, molecular pharmacology, molecular biology of peptide hormones and neurotransmitters and their receptors, transduction systems and in the design, synthesis and bio evaluation of novel ligands for the treatment of degenerative diseases.

Professor Hruby’s research has been primarily in the chemistry, conformation-biological activity relationships, molecular mechanisms of information transduction and of molecular diseases associated with peptide hormones and neurotransmitters and their receptors that modulate health, disease and human behavior. Specific methods and approaches used in this research include: de novo design of biologically active peptides and peptidomimetics; peptide and peptidomimetic synthesis; asymmetric synthesis; design and asymmetric synthesis of novel amino acids; computational chemistry; conformational analysis using NMR, X-ray crystallography and other biophysical tools; combinatorial chemistry; conformation-biological activity relationships; the design, synthesis and biological evaluation of peptide and peptide mimetic ligands that affect pain, addictions, feeding behaviors, pigmentation, sexual behavior and motivation, glucose homeostasis, cancer and other biological effects; peptide mimetic design; and the structure-function of G-protein coupled receptors. The Hruby group also is developing new synthetic methodologies for the assembly of multimeric ligands for the detection and treatment of pain, cancer and other diseases; a new approach to design of ligands for disease states involving the concept of overlapping pharmacophores to address several receptors simultaneously in a single molecular ligand.

In his current role he is responsible for all internal drug discovery projects at C4X Discovery as well as continued development of the technology in the context of application to drug discovery.

The spotlight in drug discovery and design has been firmly centred on “quality” and “efficiency” in an endeavour to improve productivity and reduce high development attrition rates. In particular, much attention has been focused on measured and predicted drug property optimization because this is expected to significantly impact both the quality and the efficiency of drug design. With such a dominating focus, it is right to ask if other important aspects of drug design are being generally overlooked by the medicinal and computational chemistry community. This presentation aims to make a case for the increasingly clear importance (and therefore necessary adoption) of conformational design in harmony with property optimization. It is argued that the impact of creatively applied conformational design based on a validated experimental foundation will lead to a number of benefits and can be far reaching. For example, limiting shape diversity whilst gaining a deep understanding of shape giving structural features presents a complementary approach to property based design. It will lead to a tighter integration of the highly complementary medicinal and computational chemistry workflows. And importantly, it will provide undoubtedly a driver to re-invigorate the development and creative exploitation of experimental methods aimed at describing and predicting the conformational behaviour of small molecules in solution. Hence, conformational design based on experimental evidence offers new drivers for innovation in drug discovery.

Mitsuji Yamashita was born in 1944 and has completed his PhD at the age of 27 years from Nagoya University, Japan, and postdoctoral studies from Toyota Science and Chemistry Research Institute, Japan, and Iowa State University, USA. He was a visiting professor of University of Massachusetts at Amherst, USA, and a researcher of Oxford University, UK, in 1994. He was promoted to be a professor of Graduate School of Science and Technology, Shizuoka University, Japan, in 1998 and retired at the age of 65 years old, and he is now a professor emeritus and specially-appointed professor of Shizuoka University, Japan. His research field is now focused on medicinal materials based on chemistry of carbohydrates and heterocycles. He has published more than 175 papers and patents as well as four books. Mitsuji Yamashita is now mainly concentrating in the research and development of phospha sugar antitumor agents and sugar dendritic Gd-DTPA MRI contrast agents for innovating in medical treatment for cancer patients.

By this research, novel multiple type low-molecular-weight antitumor agents of phospha sugar derivatives, which target IER5/Cdc25B and innovate in chemotheraputic treatment for cancer patients of various type of cancer cells, are developed. Sugar derivatives, whose oxygen atom in the hemiacetal ring is replaced by a nitrogen or a sulfur atom, etc., are called as pseudo sugars and well investigated. Among pseudo sugars phospha sugars in which the oxygen atom in the hemiacetal ring of sugars is replaced by a phosphorus moiety are not so well investigated in spite of important biological activities being expected for the pseudo sugar analogues. We have developed novel synthetic methodologies for preparing phospha sugar derivatives and constructed their compound library, and then preclinical evaluations have been carried out. Among the compound library of the phospha sugar derivatives, branched novel low-molecular-weight di- and tri-bromo deoxyphospha sugar derivatives (DBMPP and TBMPP) as well as some substituted phospha sugar analogues were found to exert novel, potential, and wide spectral antitumor activities by MTT in vitro evaluation method. The characterization and mechanism elucidation of these phospha sugar derivatives by flow cytometry and Western blotting showed that phospha sugars DBMPP and/or TBMPP enhanced the expression of cancer suppressors and suppressed the expression of cancer accelerators. Phospha sugar derivative TBMPP enhanced the expression of IER5 and then suppressed the expression of Cdc25B, which is the common and essential factor to act at the mitosis stage of the tumor cell cycles. Therefore, phospha sugar derivatives might induce apoptosis at G2/M stage and inhibit various kinds of cancer cells’ growth. In vivo evaluation for TBMPP against K562 cell transplanted to a nude mouse was checked visually to be successful. We are expecting that phospha sugars may be developed to be clinically useful novel antitumor agents.
