A new and short fragment-based approach towards artificial (but "natural-based") complex polyphenols has been developed, exploiting the Ugi multicomponent reaction of phenol-containing simple substrates. The resulting library of compounds has been tested for its capacity to inhibit β-amyloid protein aggregation, as a possible strategy to develop new chemical entities to be used as prevention or therapy for Alzheimer's disease. Some of the members of this library have demonstrated, in thioflavin assays, a highly promising activity in inhibiting aggregation for two β-amyloid peptides: Aβ1-42 and the truncated AβpE3-42.

Using fragment-based design strategy, new pyridyl-indole hybrids 4a-y and indole intermediates 3a-e were synthesized using multicomponent one pot reaction. The synthesized compounds were subjected to screening for antimalarial activity against chloroquine sensitive (D6) and chloroquine resistant (W2) strains of Plasmodium falciparum. Several compounds exhibited antimalarial activity with IC values in the range of 1.

Fragment-based drug design has been successfully applied to challenging targets where the detection of the weak protein-ligand interactions is a key element. H saturation transfer difference (STD) NMR spectroscopy is a powerful technique for this work but it requires pure homogeneous proteins as targets. Monoclonal antibody (mAb)-relayed N-GS STD spectroscopy has been developed to resolve the problem of protein mixtures and impure proteins.
