The Drug Discovery Program addresses a range of problems at the interface of chemistry, biology, modeling, data mining, engineering, and medicine, including medicinal chemistry and chemical biology. The Program focuses on research questions relevant to the development of functional small molecules with specific physicochemical or biological properties; including protein-ligand interaction, property prediction, electronic structure modeling, chemical synthesis, materials, dynamics and kinetics, and basic drug discovery. The Program also addresses chemical information analysis, data mining, and knowledge generation via semantic integration.

Vision

The Drug Discovery Program’s vision is to develop a translational drug informatics platform as a foundation to address the complex challenges in the development of chemical probes and human therapeutics, including accelerating the process and increasing the probability of success. Such a system must provide in-silico-analogous functionality of all aspects of an optimization cycle (testing, hypothesis development / refinement, synthesis, testing) in the different stages of (preclinical) development. It is built on various computational components, algorithms, data sources, ontologies, etc., which are integrated in a flexible modular architecture. The goal is to derive, capture, and effectively utilize knowledge from all accessible relevant internal and external data sources and tools, and from expert scientists.

 

Chemoinformatics Overview

Chemoinformatics and computer‐aided drug design methods play increasingly important roles in preclinical and translational drug research. To develop small molecule therapeutics and chemical probes, computational chemistry approaches are important to gain mechanistic insights and build models related to efficacy, ADME (absorption, distribution, metabolism, excretion), PK (pharmacokinetics), pharmacology, and toxicity. Chemoinformatics tools are also needed to analyze and extract knowledge from the enormous data sets that are generated by high‐throughput screening methods in the pharmaceutical industry, and also in the public domain (such as PubChem). The complexity of the drug discovery process manifests itself in high rates of clinical attrition primarily due to lack of efficacy and clinical safety (toxicity). Advances in systems biology and our increased knowledge in human genetics, functional genomics, and molecular biology hold the promise to expand the drug discovery paradigm from single‐target selective “blockbuster” drugs towards developing multi‐target drugs (polypharmacology) and individualized medicines.

The Center for Computational Science’s goal is to integrate chemoinformatics, computational biology, and bioinformatics methods to develop a translational drug‐informatics platform as a necessary component to address these complex problems. The Drug Discovery Program uses a distributed and parallelized computing environment for many of our modeling and data analysis procedures. On a number of projects, the team is working on innovative computational‐driven approaches and technologies that are relatively broadly targeted at the analysis and modeling at life science data with the goal towards developing small molecule chemical probes and human therapeutics.

Dr. Qiong Cheng joined the University of Miami’s Center for Computational Science in February 2014. Dr. Cheng graduated from Georgia State University in December 2009 with a PhD in Computer Science. Upon graduating, She spent a little over a year training in CCS and then began work as a researcher with the Department of Computer Science at the University of Illinois in Urbana-Champaign.

Dr. Cheng’s research papers cover diverse fields such as modeling and simulation, parallel and distributed computing, and bioinformatics. Her interdisciplinary projects were published in PLOS Genetics, Bioinformatics, and Genome Research with a broad range of topics such as modeling and analysis of gene regulatory mechanisms, metabolic network analysis and comparison, conflict-sensitive dynamics prediction of phospherylation networks and protein-protein interaction networks. One of her first-author papers has been voted in “top 10 papers in regulatory genomics for 2012-13”. She was also awarded the GSU Molecular Basis of Disease Fellowship in 2007, 2008, and 2009.

Her primary research interest lie in the application of machine learning, data mining, graph algorithms, and parallel and distributed computing in designing and analysis of algorithms for solving the problems in molecular biology and disease studies.

I am a computational scientist working on the development of methods and algorithms for the experimental design, analysis and modeling of biological systems. I received B.S. and M.S. in Statistics from the University of Venice (Italy), and a Ph.D. from The Microsoft Research – University of Trento Centre for Computational and Systems Biology (Italy). I’m fascinated by the systemic approach in trying to understand biology, and more recently, I brought it to the synthetic level, trying to build artificial cells that can interact with natural ones.

I joined the University of Miami in February 2016, and am working on the challenging but fascinating LINCS project (Library of Integrated Network-based Cellular Signatures) as part of the BD2K-LINCS Data Coordination and Integration Center.

I am a Medicinal Chemist in the PhD program at the University of Miami Miller School of Medicine in the department of Molecular and Cellular Pharmacology. My projects are focused on the rational design and synthesis of small libraries for the treatment of disease with “dark” targets or multiple targets through polypharmacology. Some of this work has been a part of the NIH common fund project “illuminating the Druggable Genome”. Currently, I am developing novel pre-clinical compounds for psuedokinase NACK inhibition (chemotheraputic), Wnt inhibition (addiction) and dual kinase/BRD4 inhibition (epigenetic chemotheraputic).

Our approach to lead compound identification involves the incorporation of pheno and genotypic cell-based screening data sets, large-scale data analysis, machine learning techniques, virtual library design and computational docking studies. With these powerful tools in hand, there’s a much better sense of what compounds should be synthesized.

I am also fortunate to be involved in the NIH common fund project Library of Integrated Network of Cell-Based Signatures (LINCS) where I lend my knowledge of organic chemistry towards small-molecule compound standardization pipelines for the LINCS data portal. This incredible opportunity has also facilitated a collaboration with The Broad Institute of MIT and Harvard on the design of very unique libraries for in-vitro screening.

My research interests include biomimetic synthesis, dearomatization strategies, photochemical methodologies, natural product fragment-based drug design, drug design for neuropsychiatric disease, and chemical optogenetics.
