Abstract: Sirtuins (SIRTs), class III HDAC (Histone deacetylase) family proteins, are associated with cancer, diabetes, and other age-related disorders. SIRT1 and SIRT2 are established therapeutic drug targets by regulating its function either by activators or inhibitors. Compounds containing indole moiety are potential lead molecules inhibiting SIRT1 and SIRT2 activity. In the current study, we have successfully synthesized 22 indole derivatives in association with an additional triazole moiety that provide better anchoring of the ligands in the binding cavity of SIRT1 and SIRT2. In-vitro binding and deacetylation assays were carried out to characterize their inhibitory effects against SIRT1 and SIRT2. We found four derivatives, 6l, 6m, 6n, and 6o to be specific for SIRT1 inhibition; three derivatives, 6a, 6d and 6k, specific for SIRT2 inhibition; and two derivatives, 6s and 6t, which inhibit both SIRT1 and SIRT2. In-silico validation for the selected compounds was carried out to study the nature of binding of the ligands with the neighboring residues in the binding site of SIRT1. These derivatives open up newer avenues to explore specific inhibitors of SIRT1 and SIRT2 with therapeutic implications for human diseases. 2019 Elsevier Inc.
