Small molecules interfering with posttranslational modification of histones are of interest as tools to study epigenetic regulation of gene transcription. Specifically, drugs that interfere with histone deacetylation could be useful to induce differentiation, growth arrest as well as apoptotic cell death in tumor cells. One class of histone deacetylases is known as sirtuins some of which (Saccharomyces cerevisiae Sir2) are for example inhibited by the lactone splitomicin leading to telomeric silencing in yeast. However, splitomicin is only a micromolar inhibitor of yeast Sir2 and does not inhibit human subtypes and the lactone is prone to hydrolytic ring opening. In preliminary SAR-studies, splitomicin analogs lacking this hydrolytically labile ring were described as inactive while the naphthalene moiety could successfully be replaced by smaller aromatic rings in a fragment-like dihydrocoumarin. Here we report the synthesis and biological activity of a series of hydrolytically stable analogs with activity against human SIRT1 and 2. These comparatively small compounds characterized by high ligand efficiency are used as a starting point toward the development of specific inhibitors of histone deacetylases from the class of sirtuins.

A screening hit 1 against Trypanosoma brucei methionyl-tRNA synthetase was optimized using a structure-guided approach. The optimization led to the identification of two novel series of potent inhibitors, the cyclic linker and linear linker series. Compounds of both series were potent in a T. brucei growth inhibition assay while showing low toxicity to mammalian cells. The best compound of each series
