Article Title: Virtual Screening in the Identification of Sirtuins’ Activity Modulators

doi: 10.3390/molecules27175641

Figure Lengend Snippet: Perspective of the computational studies leading to the identification of selective and/or pan-Sirtuins modulators (shown in green). The chemical structure and the explored biological activity of the discovered hit compounds are reported. The applied virtual screening (VS) strategy is specified as structure-based (SBVS) or ligand-based (LBVS) methodology. The results are listed based on the sirtuin type (alternatively in gray and cyan), according to SBVS followed by LBVS and combined SB-LB approaches, as chronological order. Data about parasitic sirtuins (depicted in coral) are also detailed, referring to the Leishmania (Lm-Sirt), Trypanosoma cruzi (Tc-Sirt) and Schistosoma mansoni (Sm-Sirt) sirtuins.
