Network based approaches to drug repurposing for Covid-19. a) Different biological entities related to Covid-19 disease pathogenesis and drugs in general which are later used to create a network. b) Network created can be analyzed based on network proximity, AI on graphs, and network diffusion for repurposing the potential drugs. Finally, c) shows the different Insilico, in-vitro, and in-vivo validation methods for results obtained.
