Discovery of novel Cyclophilin D inhibitors starting from three dimensional fragments with millimolar potencies

Fragment-based screening by SPR enabled the discovery of chemical diverse fragment hits with millimolar binding affinities to the peptidyl-prolyl isomerase Cyclophilin D (CypD). The CypD protein crystal structures of 6 fragment hits provided the basis for subsequent medicinal chemistry optimization by fragment merging and linking yielding three different chemical series with either urea, oxalyl or amide linkers connecting millimolar fragments in the S1′ and S2 pockets. We successfully improved the in vitro CypD potencies in the biochemical FP and PPIase assays and in the biophysical SPR binding assay from millimolar towards the low micromolar and submicromolar range by > 1000-fold for some fragment derivatives. The initial SAR together with the protein crystal structures of our novel CypD inhibitors provide a suitable basis for further hit-to-lead optimization.

Polypropylene/polyamide blend featuring mechanical interlocking via controlled interfacial diffusion and recrystallization

The prevalent way to enhance interface interaction of immiscible polymer blend is adding some low molecular weight compatibilizers with soft nature, unfortunately throwing negative effects on the final mechanical strength. Here, an interfacial interlocking design strategy for immiscible polypropylene (PP)/polyamide (PA) blend is proposed. The formation process involves aryl amide-based compounds firstly were selectively enriched in PA phase, followed by controlled release and recrystallization at the subsequent annealing process, into fiber-like crystals at the interface. Accordingly, the blend featuring mechanical interlocking was successfully prepared, where the interfacial grown fibers functioned as interlocks to integrate the two immiscible components via large interfacial friction. Furthermore, the density and dimension of the interfacial fibers were tailored by adjusting the annealing temperatures. Specially, at the elevated temperature, the large and dense fibers were generated at the interface to offer stronger interfacial friction, which in turn strengthened the interfacial interaction. The interfacial topological regulation can effectively solve the interfacial problems and also can extend broadly to the other immiscible bi-phase systems. (c) 2017 Elsevier Ltd.

Frozen Microemulsions for MAPLE Immobilization of Lipase

Candida rugosa lipase (CRL) was deposited by matrix assisted pulsed laser evaporation (MAPLE) in order to immobilize the enzyme with a preserved native conformation, which ensures its catalytic functionality. For this purpose, the composition of the MAPLE target was optimized by adding the oil phase pentane to a water solution of the amino acid 3-(3,4-dihydroxyphenyl)-2-methyl-l-alanine (m-DOPA), giving a target formed by a frozen water-lipase-pentane microemulsion. Fourier transform infrared (FTIR) spectroscopy and atomic force microscopy (AFM) were used to investigate the structure of MAPLE deposited lipase films. FTIR deconvolution of amide I band indicated a reduction of unfolding and aggregation, i.e., a better preserved lipase secondary structure in the sample deposited from the frozen microemulsion target. AFM images highlighted the absence of big aggregates on the surface of the sample. The functionality of the immobilized enzyme to promote transesterification was determined by thin layer chromatography, resulting in a modified specificity.

Transition-Metal-Free Activation of Amides by N-C Bond Cleavage

The amide bond N-C activation represents a powerful strategy in organic synthesis to functionalize the historically inert amide linkage. This personal account highlights recent remarkable advances in transition-metal-free activation of amides by N-C bond cleavage, focusing on both (1) mechanistic aspects of ground-state-destabilization of the amide bond enabling formation of tetrahedral intermediates directly from amides with unprecedented selectivity, and (2) synthetic utility of the developed transformations. Direct nucleophilic addition to amides enables a myriad of powerful methods for the formation of C-C, C-N, C-O and C-S bonds, providing a straightforward and more synthetically useful alternative to acyl-metals.

Ni-Catalyzed cross-coupling reactions of N-acylpyrrole-type amides with organoboron reagents

The catalytic conversion of amides to ketones is highly desirable yet challenging in organic synthesis. We herein report the first Ni/bisNHC-catalyzed cross-coupling of N-acylpyrrole-type amides with arylboronic esters to obtain diarylketones. This method is facilitated by a new chelating bis-NHC ligand. The reaction tolerates diverse functional groups on both arylamide and arylboronic ester partners including sensitive ester and ketone groups.

Changes in the cannabinoids receptors in rats following treatment with antidepressants

The endocannabinoid (eCB) system plays a significant role in the pathophysiology of depression. The potential participation of this system in the mechanism of action of antidepressants has been highlighted in recent years. The aim of this study was to investigate the expression of cannabinoid (CB) receptors using Western blot and CBI receptor density using autoradiography after acute or chronic administration of antidepressant drugs [imipramine (IMI, 15 mg/kg), escitalopram (ESC, 10 mg/kg) and tianeptine (TIA, 10 mg/kg)]. Antidepressants given chronically elevated CB1 receptor density in the cortical structures and hippocampal areas, while a decrease of CB1 receptor density was observed in the striatum after IMI and ESC treatment. The CB1 receptor expression decreases in the dorsal striatum after chronic administration of IMI and ESC or the receptor rise in the hippocampus after chronic ESC and TIA treatment were confirmed using Western blot analyses. An increase in the CB2 receptor expression was observed in the cortical structures and hippocampus after chronic administration of ESC and TIA, while a decrease in this expression was noted in the striatum and cerebellum after chronic IMI treatment. Our results provide clear evidence that the antidepressant exposures provoke some modulations within the eCB system through CB receptors. (C) 2017 Elsevier B.V. All rights reserved.

Enantioselective Alkylamination of Unactivated Alkenes under Copper Catalysis

An enantioselective addition reaction of various alkyl groups to unactivated internal alkenes under Cu catalysis has been developed. The reaction uses amide-linked aminoquinoline as the directing group, 4-alkyl Hantzsch esters as the donor of alkyl radicals, and rarely used biaryl diphosphine oxide as a chiral ligand beta-lactams featuring two contiguous stereocenters at C beta and the beta substituent can be obtained in good yield with excellent enantioselectivity. Mechanistic studies indicate that a nucleophilic addition of the alkyl radical to Cu-II-coordinated alkene is the enantio-determining step.

The Impact of Immunoglobulin G1 Fc Sialylation on Backbone Amide H/D Exchange

The usefulness of higher-order structural information provided by hydrogen/deuterium exchange-mass spectrometry (H/DX-MS) for the structural impact analyses of chemical and post-translational antibody modifications has been demonstrated in various studies. However, the structure-function assessment for protein drugs in biopharmaceutical research and development is often impeded by the relatively low-abundance (below 5%) of critical quality attributes or by overlapping effects of modifications, such as glycosylation, with chemical amino acid modifications; e.g., oxidation or deamidation. We present results demonstrating the applicability of the H/DX-MS technique to monitor conformational changes of specific Fc glycosylation variants produced by in vitro glyco-engineering technology. A trend towards less H/DX in Fc C gamma 2 domain segments correlating with larger glycan structures could be confirmed. Furthermore, significant deuterium uptake differences and corresponding binding properties to Fc receptors (as monitored by SPR) between alpha-2,3- and alpha-2,6-sialylated Fc glycosylation variants were verified at sensitive levels.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 7396-58-9, you can contact me at any time and look forward to more communication. HPLC of Formula: C21H45N.
