Overview

• chemoinformatics - definition

• the bright past

• the grim presence

• the bright future ?


Synthesis of Properties

The most fundamental and lasting objective of synthesis is not

production of new compoundsbut

production of properties

George S. HammondNorris Award Lecture, 1968


What structure do I need for a certain property?structure-activity relationships

How do I make this structure?synthesis design

What is the product of my reaction?reaction predictionstructure elucidation

Fundamental Questions in Chemistry


Chemoinformatics - Why?

• complex relationshipsstructure - biological activitychemical reactivity

• amount of informationmany millions of compounds and reactionsmany millions of publications

however:

now all BMBF projects go into

bioinformatics


Industry

• early work on databases

• positions in chemoinformatics

however:• hardly any in-house work done anymore• mergers lead to elimination of positions


Teaching (Europe)

however:

discontinued?

only for Molecular Science students


Funding (Europe)

6th Framework program of the European Union:

several programs for Bioinformatics

however: no mention of Chemoinformatics!


What Can be Done?

• conferences

• teaching

• cooperation academia – industry

• new application areas

• funding

• organization


Germany Chemical Society (GDCh)

Division “Chemical Information” changed to“Chemical-Information-Computer (CIC)” in 1987

Workshop:Software Development in Chemistry 1986-2004German Conference on Chemoinformatics 2005


Teaching

• define curriculum in chemoinformatics

• what contents of chemoinformatics have to go into regular chemistry curricula

Round Table + Committee


Bioinformatics in Germany

Fachgruppe 4 der Gesellschaft für Informatik(Division 4 of the Society for Informatics)

• definiton of a curriculum on Bioinformatics in 1990

• was then put on the web

all positions in bioinformatics at German universities were given to computer scientists


Application Areas for Chemoinformatics

• drug design


• chemical engineering

• inorganic chemistry

• medicinal chemistry

• organic chemistry

• physical chemistry

• theoretical chemistry


Cooperation Industry - Academia

• industry: generate data

• academia: develop methods

provide academia access to data


Funding

• increase awareness for importance of Chemoinformatics

• go into committees
