Controlling the Position of Functional Groups at the Liquid/Solid Interface: Impact of Molecular Symmetry and Chirality
摘要:
With the aim of controlling the position of functional groups in a substrate-supported monolayer, a new family of functionalized linear alkyl chains was designed and synthesized, aided by molecular mechanics and dynamics simulations of its two-dimensional self-assembly on graphite. The self-assembly of these amino functionalized diamides at the liquid/solid interface was investigated with scanning tunneling microscopy. Intermolecular hydrogen-bonding interactions involving amides, combined with the effect of molecular symmetry and chirality, were found to guide the self-assembly. Control of the relative position and orientation of the amine groups was achieved, in the case of enantiopure compounds. Interestingly, racemates led to both racemic conglomerate and solid solution formation, with a concomitant loss of positional and orientational control of the amino groups as a result.
A Concise Enantioselective Synthesis ofN-Boc-(S)-2-Aminosuberic Acid
摘要:
The title compound has been enantioselectively obtained by a four-step process involving the catalytic asymmetric epoxidation of allyl alcohol 3, regio- and stereoselective oxirane opening with benzhydrylamine and one-pot oxidative cleavage-amine reprotection.

the disease results from the deletion of phenylalanine-508 (DeltaF508), leading to the accumulation of CFTR in the endoplasmic reticulum with a concomitant loss of chloride flux. We discovered that cyclictetrapeptides, such as 11, 14, and 15, are able to correct the trafficking defect and restore cell surface activity of DeltaF508-CFTR. Although this class of cyclictetrapeptides is known to contain

Histone deacetylase (HDAC) inhibitors have potential for cancer therapy. An HDAC inhibitor based on a cyclic peptide mimic of known structure, linked by an aliphatic chain to a hydroxamic acid, was designed and synthesized. The chimeric compound showed potent competitive inhibition of nuclear HDACs, with an IC50 value of 46 nM and a K-i value of 13.7 nM. The designed inhibitor showed 4-fold selectivity for HDAC1 (57 nM) over HDAC8 (231 nM).
