Recommanded Product: 192701-73-8. The article was titled 《Discovery and Structure Activity Relationship of Small Molecule Inhibitors of Toxic β-Amyloid-42 Fibril Formation》. The information in the text is summarized as follows:

Increasing evidence implicates Aβ peptides self-assembly and fibril formation as crucial events in the pathogenesis of Alzheimer disease. Thus, inhibiting Aβ aggregation, among others, has emerged as a potential therapeutic intervention for this disorder. Herein, we employed 3-aminopyrazole as a key fragment in our design of non-dye compounds capable of interacting with Aβ42 via a donor-acceptor-donor hydrogen bond pattern complementary to that of the β-sheet conformation of Aβ42. The initial design of the compounds was based on connecting two 3-aminopyrazole moieties via a linker to identify suitable scaffold mols. Addnl. aryl substitutions on the two 3-aminopyrazole moieties were also explored to enhance π-π stacking/hydrophobic interactions with amino acids of Aβ42. The efficacy of these compounds on inhibiting Aβ fibril formation and toxicity in vitro was assessed using a combination of biophys. techniques and viability assays. Using structure activity relationship data from the in vitro assays, we identified compounds capable of preventing pathol. self-assembly of Aβ42 leading to decreased cell toxicity. In the experiment, the researchers used many compounds, for example, Methyl 3-(p-tolyl)-1H-pyrazole-5-carboxylate(cas: 192701-73-8Recommanded Product: 192701-73-8)

The article was titled 《Regioselective Synthesis of C3-Hydroxyarylated Pyrazoles》, and you may find the article in Journal of Organic Chemistry.Product Details of 930-36-9 The information in the text is summarized as follows:

The first regioselective route to C3-hydroxyarylated pyrazoles obtained through reaction of pyrazole N-oxides with arynes using mild conditions is reported. Importantly, this method does not require the C4 and C5 positions of the pyrazole to be functionalized to observe regioselectivity. Using this method, authors completed the synthesis of a recently reported JAK 1/2 inhibitor. Authors’ synthesis produces the desired product in 4 steps from com. available starting materials. The results came from multiple reactions, including the reaction of 1-Methylpyrazole(cas: 930-36-9Product Details of 930-36-9)

1-Methylpyrazole(cas: 930-36-9) belongs to pyrazoles. Pyrazoles and their related multiring analogs are common elements of a wide variety of bioactive compounds. These ring structures are rare in nature. A consequence of this is that they have previously been thought to be poor moieties to include in potential new drugs. Product Details of 930-36-9

Nineteen 3-methyl-5-carboxypyrazole (I) derivatives were tested orally in rats for their capacity to lower plasma free fatty acids. Esterification or the reduction of the carboxy radical did not affect the properties of I; the presence of N1-substituted Me or benzyl reduced the lipolytic effect. 3-Methyl-5-carboxamidopyrazole (II) was the longest lasting compound II prevented and counteracted the increased deposition of liver triglycerides induced by ACTH (200 I.U./kg., given s.c.) or 50% EtOH (16 ml./kg.) and it reduced the plasma ketone body concentration in fasted animals. 16 references.

Kiplin; Johnston, Jeffrey N. published 《Organocatalytic, Diastereo- and Enantioselective Synthesis of Nonsymmetric cis-Stilbene Diamines: A Platform for the Preparation of Single-Enantiomer cis-Imidazolines for Protein-Protein Inhibition》.Journal of Organic Chemistry published the findings.Reference of 1-Methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole The information in the text is summarized as follows:

The finding by scientists at Hoffmann-La Roche that cis-imidazolines could disrupt the protein-protein interaction between p53 and MDM2, thereby inducing apoptosis in cancer cells, raised considerable interest in this scaffold over the past decade. Initial routes to these small mols. (i.e., Nutlin-3) provided only the racemic form, with enantiomers being enriched by chromatog. separation using high-pressure liquid chromatog. (HPLC) and a chiral stationary phase. Reported here is the first application of an enantioselective aza-Henry approach to nonsym. cis-stilbene diamines, e.g., I, and cis-imidazolines, e.g., II. Two novel mono(amidine) organocatalysts (MAM) were discovered to provide high levels of enantioselection (>95% ee) across a broad range of substrate combinations. Furthermore, the versatility of the aza-Henry strategy for preparing nonsym. cis-imidazolines is illustrated by a comparison of the roles of aryl nitromethane and aryl aldimine in the key step, which revealed unique substrate electronic effects providing direction for aza-Henry substrate-catalyst matching. This method was used to prepare highly substituted cis-4,5-diaryl imidazolines that project unique aromatic rings, and these were evaluated for MDM2-p53 inhibition in a fluorescence polarization assay. The diversification of access to cis-stilbene diamine-derived imidazolines provided by this platform should streamline their further development as chem. tools for disrupting protein-protein interactions.

Acyl CoA:monoacylglycerol acyltransferase-2 (MGAT2) has emerged as a potential peripheral target for the treatment of obesity and metabolic disorders. We previously identified a novel series of N-phenylindoline-5-sulfonamide derivatives exemplified by 2 as potent and orally bioavailable MGAT2 inhibitors. Despite its attractive potency, further assessment revealed that this compound exhibited time-dependent inhibition (TDI) of cytochrome P 450 3A4 (CYP3A4). To remove the undesirable CYP3A4 TDI activity, structural modification was focused on the 2,4-difluoroaniline moiety on the basis of the assumption that this moiety would be involved in mechanism-based inhibition of CYP3A4 via oxidative metabolism This led to the finding that the introduction of 4-chloro-2,6-difluoroaniline significantly improved CYP3A4 TDI risk. Further optimization resulted in the discovery of N-(4-chloro-2,6-difluorophenyl)-1-{5-[1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl]pyrimidin-2-yl}-7-(2-oxopyrrolidin-1-yl)-2,3-dihydro-1H-indole-5-sulfonamide (27c) with potent MGAT2 inhibitory activity (IC50 = 7.8 nM) and excellent ADME-Tox profiles including metabolic stability, oral bioavailability, and CYP3A4 TDI. In a mouse oral fat tolerance test, compound 27c effectively and dose-dependently suppressed the elevation of plasma triacylglycerol levels after oral administration at doses of 1 and 3 mg/kg. We also discuss mitigation of the phototoxic liability of biaryl derivatives on the basis of the HOMO-LUMO gap hypothesis during the course of optimization efforts.

Scott published 《Discovery of a Highly Potent, Selective, and Orally Bioavailable Macrocyclic Inhibitor of Blood Coagulation Factor VIIa-Tissue Factor Complex》.Journal of Medicinal Chemistry published the findings.Recommanded Product: 847818-74-0 The information in the text is summarized as follows:

Inhibitors of the tissue factor (TF)/factor VIIa complex (TF-FVIIa) are promising novel anticoagulants, which show excellent efficacy and minimal bleeding in preclin. models. Starting with an aminoisoquinoline P1-based macrocyclic inhibitor, optimization of the P’ groups led to a series of highly potent and selective TF-FVIIa inhibitors, which displayed poor permeability. Fluorination of the aminoisoquinoline reduced the basicity of the P1 group and significantly improved permeability. The resulting lead compound I was highly potent, selective, and achieved good pharmacokinetics in dogs with oral dosing. Moreover, it demonstrated robust antithrombotic activity in a rabbit model of arterial thrombosis.

4-Aminopyridines are valuable scaffolds for the chem. industry in general, from life sciences to catalysis. We report herein a collection of structurally diverse polycyclic fused and spiro-4-aminopyridines that are prepared in only three steps from com. available pyrimidines. The key step of this short sequence is a [4 + 2]/retro-[4 + 2] cycloaddition between a pyrimidine and an ynamide, which constitutes the first examples of ynamides behaving as electron-rich dienophiles in [4 + 2] cycloaddition reactions. In addition, running the ihDA/rDA reaction in continuous mode in superheated toluene, to overcome the limited scalability of MW reactions, results in a notable production increase compared to batch mode. Finally, d. functional theory investigations shed light on the energetic and geometric requirements of the different steps of the ihDA/rDA sequence.
