WebChromopynones 1 provide an illustrative example for pseudo-NP design and synthesis.21 They embody a bridged-bicyclic scaffold which combines the fragments for widely occurring, bioactive chromane and tetrahydropyrimidinone NP-fragments. They were efficiently synthesised in a one-pot procedure involving a To design a representative pseudo NP class we considered basic guidelines that we expect to be applicable in a general sense. First, because chirality is a defining property of many NPs, and stereogenic content correlates with bioactivity19,20, it was planned to combine NP fragments in a novel three-dimensional … See more To compare the chemical space occupied by the chromopynones, NP-likeness scores, as introduced in ref. 23 (Fig. 3a and Supplementary … See more Pseudo NPs may display bioactivities that are very different from those of the individual guiding NPs from which the newly combined fragments were derived. Therefore, this chemocentric approach requires a wider … See more Selectivity for inhibition of the two most cancer-relevant glucose transporters, GLUT-1 and -340,41, was assessed with human colorectal adenocarcinoma DLD-1 cells, which mainly express GLUT-1 and GLUT-3 (as reported … See more For inhibition of glucose uptake by the chromopynones a clear structure–activity relationship emerged. Thus, the substitution pattern around the fused phenyl ring was important for activity and potency (Table 1, … See more
