Predicting novel targets for existing drugs using side effect information

Lars Juhl Jensen

the problem

new uses for old drugs

drug–drug network

shared target(s)

chemical similarity

Campillos & Kuhn et al., Science, 2008

similar drugs share targets

only trivial predictions

the idea

chemical perturbations

phenotypic readouts

drug treatment

side effects

the implementation

information on side effects

package inserts

text mining

side-effect ontology

backtracking

side-effect correlations

GSC weighting

side-effect frequencies

raw similarity score

p-values

side-effect similarity

chemical similarity

reference set

drug–target pairs

drug–drug pairs

score bins

benchmark

fit calibration function

probabilistic scores

the results

drug–drug network

ATC codes

categorization

map onto score space

the experiments

20 drug–drug relations

in vitro binding assays

Ki<10 µM for 11 of 20

cell assays

9 of 9 showed activity

the future

target side-effect profiles

drug–target network

integration with STITCH
