  Discovery and evaluation of spirocyclic derivatives as antagonists of the neuropeptide Y5 receptor

  摘要：

  A novel series of spirocyclic derivatives was synthesized and evaluated as NPY Y5R antagonists for the treatment of obesity. Cis and trans analogs 7a and 8a were equipotent in a Y5R binding assay (K-i's <= 1 nM) and displayed good stability in human and rat liver microsome preparations. Compound 7a failed to demonstrate weight loss activity in a diet-induced obese (DIO) rat model at unbound drug levels in the brain that exceeded the Y5R K-i value by 25-fold over a 24-h time-period.

  Practical Synthesis of (1s,4s)-4-(Methylamino)-1′H-spiro[cyclohexane-1,3′-furo[3,4-c]pyridin]-1′-one

  摘要：

  A practical and scalable process for the preparation of (1s,4s)-4-(methylamino)-1'H-spiro[cyclohexane-1,3'-furo[3,4-c]pyridin]-1'-one 2a, a highly functionalized and potentially useful building block for pharmaceutical research is described. The material is prepared via an efficient two-step sequence from readily available materials and is isolated as a single diastereomer in high chemical purity.
