  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.

  Fatty acid synthase (FAS) is necessary for growth and survival of tumor cells and is a promising drug target for oncology. Here, we report oil the syntheses and activity of novel inhibitors of the thioesterase domain of FAS. Using the structure of orlistat as a starting point, which contains a beta-lactone as the central pharmacophore, 28 novel congeners were synthesized and examined. Structural features such as the length of the alpha- and beta-alkyl chains, their chemical composition, and arnino ester substitutions were altered and tile resulting compounds explored for inhibitory activity toward the thioesterase domain of FAS. Nineteen congeners show improved potency for FAS in biochemical assays relative to orlistat. Three of that subset, including the natural product valilactone, also display all increased potency in inducing tumor cell death and improved solubility compared to orlistat. These findings Support the idea that all orlistat congener can be optimized for use in a preclinical drug design and for clinical drug development.

  An efficient enantioselective synthesis of sphinganine and clavaminol H is reported. These sphingoid-type bases were obtained from commercially available fatty acids using highly enantioselective Ru-catalyzed hydrogenation and organocatalytic electrophilic amination reactions to create the stereogenic centers.
