3D representation of the Anti-Neoplastic-Nervous system feature space using the t-SNE algorithm for dimension reduction. Two Anti-Neoplastic compounds (two blue dots in the black square) are markedly different from the rest of the Anti-neoplastic bulk. They correspond to compounds fluorouracil (5-FU), an atypically small compound – one ring –, and to pentostatin, also a small, polar compound; both of them acting as nucleoside analogs.
