  Cryptocaryols A and B: Total Syntheses, Stereochemical Revision, Structure Elucidation, and Structure–Activity Relationship

  摘要：

  The first total syntheses and structural elucidation of cryptocaryol A and ayptocaryol B were achieved in 23 and 25 linear steps, respectively. The synthesis relied on the use Of a key pseudo-C, symmetric pentaol intermediate, which in a stereochemically divergent manner was converted into either enantiomer as well as diastereomers. This synthetic effort enabled the first structure-activity relationships of this class of PDCD4 stabilizing natural products.

  The synthetic cryptocaryols A and B and a series of their analogues have been evaluated for their cytotoxicity and their ability to stabilize the tumor suppressor PDCD4. Cytotoxicities in the 3 to 30 mu M range were found. Both the cytotoxicity and PDCD4 stabilizing ability were tolerant of large stereochemical changes to the molecule. Co-dosing studies with cryptocaryols A and B and several known cancer drugs showed no measuable enhancement in cancer drug cytotoxicity.
• Hydrogen-Bond Networks: Strengths of Different Types of Hydrogen Bonds and An Alternative to the Low Barrier Hydrogen-Bond Proposal

  We report quantifying the strengths of different types of hydrogen bonds in hydrogen-bond networks (HBNs) via measurement of the adiabatic electron detachment energy of the conjugate base of a small covalent polyol model compound (i.e., (HOCH2CH2CH(OH)CH2)(2)CHOH) in the gas phase and the pK(a) of the corresponding acid in DMSO. The latter result reveals that the hydrogen bonds to the charged center and those that are one solvation shell further away (i.e., primary and secondary) provide 5.3 and 2.5 pK(a) units of stabilization per hydrogen bond in DMSO. Computations indicate that these energies increase to 8.4 and 3.9 pK(a) units in benzene and that the total stabilizations are 16 (DMSO) and 25 (benzene) pK(a) units. Calculations on a larger linear heptaol (i.e., (HOCH2CH2CH(OH)CH2CH(OH)CH2)(2)CHOH) reveal that the terminal hydroxyl groups each contribute 0.6 pK(a) units of stabilization in DMSO and 1.1 pK(a) units in benzene. All of these results taken together indicate that the presence of a charged center can provide a powerful energetic driving force for enzyme catalysis and conformational changes such as in protein folding due to multiple hydrogen bonds in a HBN.
