Cholesteryl ester transfer protein (CETP) inhibitors based on cyclic urea, bicyclic urea and bicyclic sulfamide cores

Cholesteryl ester transfer protein (CETP) inhibitors reduce the transfer of cholesteryl esters from the high-density lipoprotein (HDL-C) to apolipoprotein such as VLDL/LDL, with exchange of triglycerides. Thus, this inhibition increases the HDL-C levels, which is believed to lower the risk for heart disease and stroke. We report here a series of CETP inhibitors based on the cyclic, bicyclic urea and sulfamide cores. These CETP inhibitors exemplified by 15, 31, and 45 demonstrated in vitro potency in inhibiting the CETP transfer activity, and 15, 31 showing in vivo efficacy to increase HDL-C levels in cynomolgus-CETP transgenic mice. The synthesis and biological evaluations of these CETP inhibitors are described.

Visible-light-mediated borylation of aryl and alkyl halides with a palladium complex

Palladium catalyzed visible-light-mediated borylation of inactivated aryl and alkyl halides is reported; the method provided high yields and excellent functional group compatibility. Furthermore, arylsilicates were synthesized selectively using dimethylphenylsilyl boronic ester via changing the reaction conditions. Finally, the possible reaction mechanism is determined through fluorescence quenching and turn on/off experiments.

Luminescent tungsten(vi) complexes as photocatalysts for light-driven C-C and C-B bond formation reactions

The realization of photocatalysis for practical synthetic application hinges on the development of inexpensive photocatalysts which can be prepared on a large scale. Herein an air-stable, visible-light-absorbing photoluminescent tungsten(vi) complex which can be conveniently prepared at the gram-scale is described. This complex could catalyse photochemical organic transformation reactions including borylation of aryl halides, such as aryl chloride, reductive coupling of benzyl bromides for C-C bond formation, reductive coupling of phenacyl bromides, and decarboxylative coupling of redox-active esters of alkyl carboxylic acid with high product yields and broad functional group tolerance.

Reversible Covalent End-Capping of Collagen Model Peptides

The combination of supramolecular aggregation of collagen model peptides with reversible covalent end-capping of the formed triple helix in a single experimental set-up yielded minicollagens, which were characterized by a single melting temperature. In spite of the numerous possible reaction intermediates, a specific synthetic collagen with a leading, middle and trailing strand is formed in a highly cooperative self-assembly process.

Diverse Multi-Functionalized Oligoarenes and Heteroarenes for Porous Crystalline Materials

A modular synthesis of multi-functionalized biphenyl, terphenyl and higher linear oligophenylene dicarboxylic acids and pyridine-terminated oligoarenes by stepwise palladium–catalyzed borylation/Suzuki–Miyaura cross-coupling reactions is described. The presence of several distinct functional groups such as azide, hydroxy, and alkyne, as well as coordinative functional end groups (carboxylic acid or pyridine) combined in a single oligoarene molecular unit at strategic positions offer an advantageous dual-utility. First, these compounds can serve as useful molecular bricks (ditopic organic linkers) in the construction of complex porous crystalline materials. Second, after the assembly into the crystalline coordination networks, orthogonal functional sites within the linker-backbone offer tremendous potential from application perspectives as they can be modified by a wide range of post-synthetic modifications including azide–alkyne click chemistry. This allows further tailoring of the supramolecular assemblies to yield novel multifunctional materials.

Self-assembly of peptide boroxoles on cis-dihydroxylated oligoamide templates in water

We develop templates that can be used to stabilize consistent oligomers of a bioactive peptide. In the present study, we synthesize oligomers of an antibody epitope from the amyloidogenic prion protein. Dynamic covalent chemistry is the basis for the spontaneous condensation of 2, 3, 4 or 6 peptides with qualified polyol templates presenting the required number of bioorthogonal ligation sites. To study this process in aqueous solution, the N-terminal amino acid of a 13-mer peptide is first acylated with 4-carboxy-benzoboroxole (1-hydroxy-1,3-dihydrobenzo[c][1,2] oxaborole-5-carboxylic acid) and then mixed with the template to obtain self-assembled miniamyloids of specified degree of oligomerization. The template is assembled from bicyclic dipeptides of alternating d- and l-stereochemistry. The cis-diol group of this dipeptide hot=Tap (hot: d-hydroxythreonine, Tap: l-thiaproline) has sufficiently high affinity for boroxoles in water. A single N3-hot=Tap-OMe dipeptide template forms a 1?:?1 complex with 4-carboxy-benzoboroxole with excellent diastereoselectivity. The oligomeric template N3-(hot=Tap)n-OMe (n?=?2, 3, 4 or 6) presents a regular pattern of 2, 3, 4 or 6 cis-diol groups for the spontaneous esterification with the same number of boronic acids. Nuclear magnetic resonance identifies the homogenous regioselectivity and stereoselectivity of this ligation process. The combination of electron-poor benzoboroxoles with this optimized cis-diol template allows for the complete ligation under high-dilution conditions in water with only 1.3 equivalents of peptide-boroxole per diol functionality.

MOLECULAR GAUGE BLOCKS FOR BUILDING ON THE NANOSCALE

Disclosed herein is a way to produce a series of discrete sized slender, rigid oligoparaxylene molecules ranging from 1-5 nm in length. Molecules, based on 1-7, 9-11 paraxylene rings, have been synthesized as part of a homologous series of oligoparaxylenes (OPXs) with a view to providing a molecular tool box for the construction of nano architectures—such as spheres, cages, capsules, metal-organic frameworks (MOFs), metal-organic polyhedrons (MOPs) and covalent-organic frameworks (COFs), to name but a few—of well-defined sizes and shapes. Twisting between the planes of contiguous paraxylene rings is generated by the steric hindrance associated with the methyl groups and leads to the existence of soluble molecular gauge blocks without the need—at least in the case of the lower homologues—to introduce long aliphatic side chains onto the phenylene rings in the molecules.
