Table of Contents Ø Introduction Ø History Timeline Drug discovery Ø Products and Development IC CCR WOK Ø Drug discovery- today Ø Current TR-Integrety TR-Cortellis Ø Summary
Chemistry - the Central Science Ø Chemistry is one of the most information-rich academic disciplines Ø Integrates well with biology, physics and math Ø Has played a vital role - from the Renaissance to rockets, from nanotechnology to DNA mapping Ø Language of chemistry is universal and is widely used in other disciplines Introduction
TIMELINE Late 1950-early 60 s Importance of Chemical Information Realized Ø The Institute for Scientific Information (ISI) founded by Dr. Eugene Garfield (1957) Ø CAS Registry System (1957) Ø ACS- Journal of Chemical Documentation established (1961) Ø Founding of Institute of Information Scientists (1962) 1960 s - late 70 s Time of intensive Research Ø Ø Ø Ø Ø Algorithms for (sub)structure searching Algorithms for indexing of databases for reactions Introduction of QSAR Linear non-graphic WLN, SMILES DWPI fragmentation code
TIMELINE Developmental in nature 1980-early 90 s Ø Building on techniques introduced in previous two decades Ø Methods to complement structure and substructure searching Ø Implementation of operational systems for searching chemical databases Ø Structure-generating programs allowing conversion of 2D structure databases to 3D form 1990 s- mid 2000 s Use of both biological & chemical information Ø Combinatorial synthesis with HTS Ø Genomics - the human genome project and Proteomics Ø Advances in bioinformatics and chem(o)informatics Ø Drug-discovery
DRUG DISCOVERY 1950-80 s Ø Drugs based on natural products Ø Unplanned screening Ø Informatics only superficial Ø Data primarily from in vivo testing Ø Intuition Ø Serendipity
INDEX CHEMICUS(IC) for Print Documentation

CURRENT CHEMICAL REACTIONS(CCR) The Print Product
Model CCR Record
Traditional documentation - challenged Ø Exponential growth of information Ø Economic limitations
From Print to Online - Web of Knowledge (WOK)
WOK-Special features
Structure Search Record in WOK
Compound Record in WOK

Reaction record in WOK
Ø Vast quantities of data Drug Discovery Today Ø Start with knowledge of a biological target and maybe a known protein structure Ø Multi-disciplinary teams share knowledge Ø Informatics is of strategic importance, supports decision making Ø High-throughput screening Ø Fail early : predict drug-likeness
Biology or Chemistry? Ø If it s green or wriggles it s biology and if it stinks it s chemistry Ø In fact now there is no clear line of demarcation between biology and chemistry- Systems Chemical biology Ø Critical areas of Systems Chemical Biology include chemical libraries with small molecules biological databases high-throughput screening computational tools
