  Total Synthesis and Comparative Analysis of Orlistat, Valilactone, and a Transposed Orlistat Derivative:  Inhibitors of Fatty Acid Synthase

  摘要：

  Concise syntheses of orlistat ( Xenical), a two-carbon transposed orlistat derivative, and valilactone are described that employ the tandem Mukaiyama aldol-lactonization (TMAL) process as a key step. This process allows facile modification of the alpha-side chain. Versatile strategies for modifying the delta-side chain are described, involving cuprate addition and olefin metathesis. Comparative antagonistic activity of these derivatives toward a recombinant form of the thioesterase domain of fatty acid synthase is reported along with comparative activity-based profiling.

  The TiCl4-mediated aldol reaction of the (E)-O-silyl ketene-O,S-acetal derived from 2-pyridyl thioester with benzaldehyde gave exclusively syn-aldol product. In contrast, BF3-mediated reaction afforded the corresponding anti-isomer as a major product. Chelation and acyclic transition state are postulated in order to explain the observed selectivities.

  beta-Lactam derivatives of orlistat were prepared and their inhibitory activities toward the thioesterase domain of fatty acid synthase (FAS-TE) were evaluated using a recombinant form of the enzyme. While in general these derivatives showed lower potency compared to beta-lactones, a reasonably potent, lead compound (-)-9 (IC50 = 8.6 mu M) was discovered that suggests that this class of compounds should be evaluated further.

• Activity-Based Proteome Profiling of Potential Cellular Targets of Orlistat − An FDA-Approved Drug with Anti-Tumor Activities

  Orlistat, or tetrahydrolipstatin (THL), is an FDA-approved antiobesity drug with potential antitumor activities. Cellular off-targets and potential side effects of Orlistat in cancer therapies, however, have not been extensively explored thus far. In this study, we report the total of synthesis of THL-like protein-reactive probes, in which extremely conservative modifications (i.e., an alkyne handle) were introduced in the parental THL structure to maintain the native biological properties of Orlistat, while providing the necessary functionality for target identification via the bio-orthogonal click chemistry. With these natural productlike, cell-permeable probes, we were able to demonstrate, for the first time, this chemical proteomic approach is suitable for the identification of previously unknown cellular targets of Orlistat. In addition to the expected fatty acid synthase (FAS), we identified a total of eight new targets, some of which were further validated by experiments including Western blotting, recombinant protein expression, and site-directed mutagenesis. Our findings have important implications in the consideration of Orlistat as a potential anticancer drug at its early stages of development for cancer therapy. Our strategy should be broadly useful for off-target identification against quite a number of existing drugs and/or candidates, which are also covalent modifiers of their biological targets.
