  1. MULTITARGET DOCKING WITH DYNAMICS COMPOUND SELECTION Compound database (~300,000) Multiple disease related proteins DRUG-LIKE (~5000 from FDA) Compound library Computational docking with dynamics High throughput screen Computational docking Experimental verificationSuccess rate +Time .Cost $$$$$ Initial candidates Initial candidates Experimental verificationSuccess rate ++Time .Cost $$$ Experimental verificationSuccess rate +++++Time .Cost $ Disease &target identification NOVEL FRAGMENT BASED TRADITIONAL SINGLE MULTITARGET SCREENING TARGET SCREENING Single disease related protein

  2. SHOTGUN MULTITARGET DOCKING WITH DYNAMICS ALL KNOWN DRUGS (~5,000 FROM FDA) FRAGMENT BASED DOCKING WITH DYNAMICS (~50,000,000) PRIORITISED HITS DISSOCIATION CONSTANTS (KD) (~300-500) + ALL TARGETS WITH KNOWN STRUCTURE (~5,000-10,000) IN VITRO STUDIES INITIAL CLINICAL TRIALS IN VIVO STUDIES CLINICAL STUDIES/APPLICATION
