  An Oral Sphingosine 1-Phosphate Receptor 1 (S1P₁) Antagonist Prodrug with Efficacy in Vivo: Discovery, Synthesis, and Evaluation

  摘要：

  A prodrug approach to optimize the oral exposure :of a series of sphingosine 1-phosphate receptor 1 (S1P(1)) antagonists for chronic efficacy studies led to the discovery of dimethylphenylsulfonylamino)-3,5-dimethylbiphenyl-4-carbonyl]-methylamino}-4-dimethylaminobutyric acid methyl ester 14. Methyl ester prodrug 14 is hydrolyzed in vivo to the corresponding carboxylic, acid 15, a potent and selective S1P(1) antagonist.: Oral; administration of the prodrug 14 induces sustained peripheral blood lymphocyte reduction.. in rats. In a rat: cardiac transplantation model coadministration of a nonefficacious dose of prodrung 14 with a nonefficacious dose of sotrastaurin (19), a protein kinase C inhibitor, or everolimus mTOR inhibitor, effectively prolonged the survival time of rat cardiac allografts. This demonstrates that clinically useful immunomodulation mediated by the S1P(1) receptor can be achieved with an S1P(1) antagonist generated in vivo after oral administration of its prodrug.

  The total synthesis of physarorubinic acid, a polyenoyltetramic acid plasmoidal pigment from Physarum polycephalum, is described in a series of steps from (E)-3-iodoacrylic acid 6 and employs aminolysis of the pentaene thioester 11 as a key synthetic step. Lacey–Dieckmann cyclisation and subsequent deprotection then affords physarorubinic acid 1 in high yield and purity.

• Fluorogenic Peptide Substrates for Serine and Threonine Phosphatases
  作者：Fengtian Xue、Christopher T. Seto

  DOI：10.1021/ol1003065

  日期：2010.5.7

  A new fluorescent assay for Ser/Thr protein phosphatases has been developed. Hydrolysis of a phosphoSer residue liberates the Ser hydroxyl group, which induces a cyclization reaction on the N-terminal carbamate and releases a fluorescent reporter. Sequence selectivity is observed using several peptide substrates against alkaline phosphatase (ALP), bacteriophage lambda protein phosphatase (lambda-PPase), and vaccinia H1 related phosphatase (VHR). These studies suggest that the assay could be a useful tool for profiling the substrate specificities of medicinally important phosphatases.
