Fig. 5From: Screening lifespan-extending drugs in Caenorhabditis elegans via label propagation on drug-protein networksThe mean chemical similarity of the 195 screened drugs (F-ratio ≥2) to the effective and ineffective drugs included in the training set. The chemical similarities were calculated according to Eq. (6), on the basis of chemical attributes retrieved from PubChem [43]Back to article page
