PPIMpred: Prediction of Protein-Protein Interaction Modulators abbreviated as "PPIMpred" is a prediction server of small molecules that inhibit Protein-Protein Interactions (PPIs). Here three popular PPIs were studied : i) Mdm2/P53 ii) Bcl2/Bak and iii) c-Myc/Max. PPIMpred may complement High-throughput Docking studies using small chemicals. It allows fast and accurate way of identifying ligand on target protein using support vector machine (SVM) based method and similarity search algorithm (Tanimoto Co-efficient). Users may have singular input and batch input Options.

SVM based method
Fill up all the fields: (* marking fields are mandatory )
Users can get values of Physico-chemical properties of various chemicals directly from PubChem (Example :
Nutlin-3a (11433190) is one of well known and clinicaly tested PPIM that can inhibit the target PPI Mdm2/P53 )
