Network, nodes and nexus: systems approach to multitarget therapeutics

► Complex diseases are an outcome of multiple triggers that precipitate into similar phenotypes. ► Systems level understanding can reveal dynamic aspects of disease progression profile. ► Correlation of metabolic remodeling to phenotypic alteration can delineate critical nodes of interventions. ► Multitargeting of key nodes of metabolic networks can be an effective therapeutic strategy. ► Robust and high-throughput data integration in conjunction with simulation would make the drug discovery process more efficient.
