Based on DrugCentral, 1795 human proteins annotated to interact with 2455 approved drugs. [ 21 ] Furthermore, it is estimated that only 10-15% of human proteins are disease modifying while only 10-15% are druggable (there is no correlation between the two), meaning that only between 1 and 2.25% of disease modifying proteins are likely to be ...
