  Design, synthesis, and kinetic evaluation of high-affinity FKBP ligands and the X-ray crystal structures of their complexes with FKBP12

  摘要：

  The design and synthesis of high-affinity FKBP12 ligands is described. These compounds potently inhibit the cis-trans-peptidylprolyl isomerase (rotamase) activity catalyzed by FKBP12 with inhibition constants (K(i,app)) as low as 1 nM, yet they possess remarkable structural simplicity relative to FK506 and rapamycin, from which they are conceptually derived. The atomic structures of three FKBP12-ligand complexes and of one unbound ligand were determined by X-ray crystallography and are compared to the FKBP12-FK506 and FKBP12-rapamycin complexes.

• P(RNCH₂CH₂)₃N:  Efficient Catalysts for Transesterifications, Acylations, and Deacylations

  Extremely strong nonionic superbases of the type P(RNCH(2)CH(2))(3)N catalyze the transesterification of carboxylic acid esters with high selectivity and yields at 25 degrees C. These bases also catalyze the deacetylation of alcohols under mild conditions in quantitative yields. Using enol acetates as acylating agents, primary and secondary alcohols are efficiently protected as acetates through the
