Improved 2,4-diarylthiazole-based antiprion agents: Switching the sense of the Amide Group at C5 leads to an increase in potency

Amide derivatives of 2,4-diarylthiazole-5-carboxylic acids were synthesised and tested for efficacy in a cell line model of prion disease. A number of compounds demonstrating antiprion activity were thereby identified from the screening libraries, showing improved potency and reproducibility of results relative to amide derivatives of the related 2,4-diphenyl-5-aminothiazole, which have been documented previously. Thus, ‘switching’ the sense of the amide bond at thiazole C5 revealed a more promising lead series of potential prion disease therapeutics. Furthermore, 3,5-diaryl-1,2,4-thiadiazoles isolated as by-products during library synthesis provided a handful of additional examples possessing an antiprion effect, thereby augmenting the set of newly identified active compounds. Evaluation of binding to cellular prion protein (PrPC) showed only weak affinities at best, suggesting that the newly identified antiprion agents do not mediate their biological effect through direct interaction with PrPC.

Synthesis of chiral nonracemic 1-(2-pyridinyl)ethylamines: Stereospecific introduction of amino function onto the 2-pyridinylmethyl carbon center

Stereospecific substitutions of optically pure 1-(pyridinyl)ethyl methanesulfonates with various amines are described. The reaction of (R)- or (S)-1-(2-pyridinyl)ethyl methanesulfonate with primary amines, including amino acid esters, gives N-substituted (S)- or (R)-1-(2-pyridinyl)ethylamines (4) with inversion of the configuration. Secondary cyclic amines are also reacted with (R)-2 to give the corresponding substituted amines (5) in excellent yields. Optically pure and meso triamine ligands having two pyridine rings, (S,S)-4f and meso-4f, (S,S)-9e, (S,R)-9e, and (S,S)-9f, have been prepared in stereochemically pure form by this method. Not only the substitution reaction of optically active 2 but also that of 1-(4-pyridinyl)ethyl and 1-(3-pyridinyl)ethyl methanesulfonates 11 and 14 take place stereospecifcally with inversion of the chiral center.

Design and synthesis of orally bioavailable 4-methyl heteroaryldihydropyrimidine based hepatitis B virus (HBV) capsid inhibitors

Targeting the capsid protein of hepatitis B virus (HBV) and thus interrupting normal capsid formation have been an attractive approach to block the replication of HBV viruses. We carried out multidimensional structural optimizations based on the heteroaryldihydropyrimidine (HAP) analogue Bay41-4109 (1) and identified a novel series of HBV capsid inhibitors that demonstrated promising cellular selectivity indexes, metabolic stabilities, and in vitro safety profiles. Herein we disclose the design, synthesis, structureactivity relationship (SAR), cocrystal structure in complex with HBV capsid proteins and in vivo pharmacological study of the 4-methyl HAP analogues. In particular, the (2S,4S)-4,4-difluoroproline substituted analogue 34a demonstrated high oral bioavailability and liver exposure and achieved over 2 log viral load reduction in a hydrodynamic injected (HDI) HBV mouse model.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C4H8O2, you can also check out more blogs about453-20-3

Elucidating the interaction of gamma-hydroxymethyl-gamma-butyrolactone substituents with model membranes and protein kinase C-C1 domains

The protein kinase C (PKC) family of proteins is an attractive drug target. Dysregulation of PKC-dependent signalling pathways is related to several human diseases like cancer, immunological and other diseases. We approached the problem of altering PKC activities by developing C1 domain-based PKC ligands. In this report gamma-hydroxymethyl-gamma-butyrolactone (HGL) substituents were investigated in an effort to develop small molecule-based PKC regulators with higher specificity for C1 domain than the endogenous diacylglycerols (DAGs). Extensive analysis of membrane-ligands interaction measurements revealed that the membrane-active compounds strongly interact with the lipid bilayers and the hydrophilic parts of compounds localize at the bilayer/water interface. The pharmacophores like hydroxymethyl, carbonyl groups and acyl-chain length of the compounds are crucial for their interaction with the C1 domain proteins. The potent compounds showed more than 17-fold stronger binding affinity for the C1 domains than DAG under similar experimental conditions. Nonradioactive kinase assay confirmed that these potent compounds have similar or better PKC dependent phosphorylation capabilities than DAG under similar experimental conditions. Hence, our findings reveal that these HGL analogues represent an attractive group of structurally simple C1 domain ligands that can be further structurally altered to improve their potencies.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 21461-84-7, help many people in the next few years.Application In Synthesis of (S)-( )-5-Oxo-2-tetrahydrofurancarboxylic Acid

Robust cobalt oxide catalysts for controllable hydrogenation of carboxylic acids to alcohols

The selective catalytic hydrogenation of carboxylic acids is an important process for alcohol production, while efficient heterogeneous catalyst systems are still being explored. Here, we report the selective hydrogenation of carboxylic acids using earth-abundant cobalt oxides through a reaction-controlled catalysis process. The further reaction of the alcohols is completely hindered by the presence of carboxylic acids in the reaction system. The partial reduction of cobalt oxides by hydrogen at designated temperatures can dramatically enhance the catalytic activity of pristine samples. A wide range of carboxylic acids with a variety of functional groups can be converted to the corresponding alcohols at a yield level applicable to large-scale production. Cobalt monoxide was established as the preferred active phase for the selective hydrogenation of carboxylic acids.
