“…These SMILES structural representations of drugs are post-processed to capture features of drug pairs associated with DDIs events [45] . Moreover, pharmacological properties such as targets [8] , [46] , enzymes, transporters, genes and proteins [6] , [47] , interaction pathways like enzymes and transporters [48] , [49] , [50] , [51] , [52] , [53] , [54] , [55] , [56] , [57] , [58] , [59] , [60] , [61] can also be manipulated to represent drugs features through a set of descriptors. Network interaction mining [62] , [63] , [64] and molecular graph representations have also been used to describe substructures of drugs that come in distinctive shapes and sizes or the structural relations between entities [65] , [66] , [67] , [68] .…”
