Zhang, Rong-Mo published the artcileThe fibrillin-1 RGD motif posttranscriptionally regulates ERK1/2 signaling and fibroblast proliferation via miR-1208, Application of 4-(5-(4-Methoxyphenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)benzenesulfonamide, the publication is FASEB Journal (2021), 35(5), e21598, database is CAplus and MEDLINE.

Fibrillin-1 is an extracellular matrix protein which contains one conserved RGD integrin-binding motif. It constitutes the backbone of microfibrils in many tissues, and mutations in fibrillin-1 cause various connective tissue disorders. Although it is well established that fibrillin-1 interacts with several RGD-dependent integrins, very little is known about the associated intracellular signaling pathways. Recent published evidence identified a subset of miRNAs regulated by fibrillin-1 RGD-cell adhesion, with miR-1208 among the most downregulated. The present study shows that the downregulated miR-1208 controls fibroblast proliferation. Inhibitor experiments revealed that fibrillin-1 RGD suppressed miR-1208 expression via c-Src kinase and the downstream JNK signaling. Bioinformatic prediction and exptl. target sequence validation demonstrated four miR-1208 binding sites on the ERK2 mRNA and one on the MEK1 mRNA. ERK2 and MEK1 are critical proliferation-promoting kinases. Decreased miR-1208 levels elevated the total and phosphorylated ERK1/2 and MEK1/2 protein levels and the phosphorylated to total ERK1/2 ratio. Together, the data demonstrate a novel outside-in signaling mechanism explaining how fibrillin-1 RGD-cell binding regulates fibroblast proliferation.

Musharrafieh, Rami published the artcileDiscovery of Quinoline Analogues as Potent Antivirals against Enterovirus D68 (EV-D68), Quality Control of 724710-02-5, the publication is Journal of Medicinal Chemistry (2019), 62(8), 4074-4090, database is CAplus and MEDLINE.

Enterovirus D68 (EV-D68) is an atypical nonpolio enterovirus that mainly infects the respiratory system of humans, leading to moderate-to-severe respiratory diseases. In rare cases, EV-D68 can spread to the central nervous system and cause paralysis in infected patients, especially young children and immunocompromised individuals. There is currently no approved vaccine or antiviral available for the prevention and treatment of EV-D68. In this study, we aimed to improve the antiviral potency and selectivity of a previously reported EV-D68 inhibitor, dibucaine, through structure-activity relationship studies. In total, 60 compounds were synthesized and tested against EV-D68 using the viral cytopathic effect assay. Three compounds 10a, 12a, and 12c were identified to have significantly improved potency (EC₅₀ < 1 μM) and a high selectivity index (>180) compared with dibucaine against five different strains of EV-D68 viruses. These compounds also showed potent antiviral activity in neuronal cells, such as A172 and SH-SY5Y cells, suggesting they might be further developed for the treatment of both respiratory infection as well as neuronal infection.

Zhu, Xinrui published the artcileOne-step preparation of ammonium-specified pyrazolium ionic liquids unveil the more popular pathway for the CO₂ fixation: Integrated experimental and theoretical studies, COA of Formula: C4H6N2, the publication is Journal of Molecular Liquids (2021), 115435, database is CAplus.

Amino-specified pyrazolium ionic liquid (APEPzBr) is synthesized by two steps. It is interesting that the product of the first step ([EPzPNH₃]Br₂) could also catalyze the coupling reaction of carbon dioxide and epoxides under 70°C along with 0.5 MPa CO₂ pressure, which is even more benign than APEPzBr. It is attributed to the strong ability of [EPzPNH₃]Br₂ to absorb CO2 along with robust electrophilic activation, which is testified by d. functional theory and ¹³C NMR measurement. The difference between [EPzPNH₃]Br₂ and APEPzBr is further elucidated by electron localization function (ELF) and atoms in mols. (AIM).

Wang, Zhen published the artcileDiscovery of an Orally Bioavailable Small-Molecule Inhibitor for the β-Catenin/B-Cell Lymphoma 9 Protein-Protein Interaction, HPLC of Formula: 724710-02-5, the publication is Journal of Medicinal Chemistry (2021), 64(16), 12109-12131, database is CAplus and MEDLINE.

Aberrant activation of Wnt/β-catenin signaling is strongly associated with many diseases including cancer invasion and metastasis. Small-mol. targeting of the central signaling node of this pathway, β-catenin, is a biol. rational approach to abolish hyperactivation of β-catenin signaling but has been demonstrated to be a difficult task. Herein, we report a drug-like small mol., ZW4864, that binds with β-catenin and selectively disrupts the protein-protein interaction (PPI) between B-cell lymphoma 9 (BCL9) and β-catenin while sparing the β-catenin/E-cadherin PPI. ZW4864 dose-dependently suppresses β-catenin signaling activation, downregulates oncogenic β-catenin target genes, and abrogates invasiveness of β-catenin-dependent cancer cells. More importantly, ZW4864 shows good pharmacokinetic properties and effectively suppresses β-catenin target gene expression in the patient-derived xenograft mouse model. This study offers a selective chem. probe to explore β-catenin-related biol. and a drug-like small-mol. β-catenin/BCL9 disruptor for future drug development.

The β-catenin/B-cell lymphoma 9 (BCL9) protein-protein interaction (PPI) is a potential target for the suppression of hyperactive Wnt/β-catenin signaling that is vigorously involved in cancer initiation and development. Herein, we describe the medicinal chem. optimization of a screening hit to yield novel small-mol. inhibitors of the β-catenin/BCL9 interaction. The best compound 30 can disrupt the β-catenin/BCL9 interaction with a K_i of 3.6μM in AlphaScreen competitive inhibition assays. Cell-based experiments revealed that 30 selectively disrupted the β-catenin/BCL9 PPI, while leaving the β-catenin/E-cadherin PPI unaffected, dose-dependently suppressed Wnt signaling transactivation, downregulated oncogenic Wnt target gene expression, and on-target selectively inhibited the growth of cancer cells harboring aberrant Wnt signaling. This compound with a new chemotype can serve as a lead compound for further optimization of inhibitors for β-catenin/BCL9 PPI.

A series of 1-(3-(2-amino-2-oxoethoxy)phenyl)piperidine-3-carboxamide derivatives I [R¹ = 2,7-diazaspiro[4.4]nonan-2-ium, 2,7-diazaspiro[4.4]nonan-2-ium, piperazin-1-ium, etc.; R² = R³ = Me, R² R³ = -CH₂-CH₂-, -CH₂-CH₂-CH₂-, etc.], II[R⁴ = H, Me, iso-Pr, etc.], III[R⁵ = 3-indolyl, indazol-4-yl, 1H-pyrrolo[2,3-b]pyridin-5-yl, etc.] were reported as new small-mol. β-catenin/B-cell lymphoma 9 (BCL9) protein-protein interaction (PPI) inhibitors. Compounds II were discovered to inhibit the β-catenin/BCL9 PPI with Ki = 0.85-2.7μM. The effects of III[R⁵ =1H-pyrrolo[2,3-b]pyridin-5-yl] on the β-catenin/BCL9 PPI in cellular context were demonstrated by β-catenin/BCL9 pull-down inhibition and dose-dependent suppression of Wnt/β-catenin signal transactivation. Notably, compound III[R⁵ =1H-pyrrolo[2,3-b]pyridin-5-yl] is more potent than ZW4864, a previously reported analog, in modulating transcription and expression of β-catenin target genes and suppressing survival of β-catenin-dependent cancer cells. The cellular on-target efficacy of III[R⁵ =1H-pyrrolo[2,3-b]pyridin-5-yl] was demonstrated by β-catenin rescue experiments Compound III[R⁵ =1H-pyrrolo[2,3-b]pyridin-5-yl] represents a promising starting point for further optimization of β-catenin/BCL9 PPI inhibitors.

Dong, Dawei published the artcileCrosslinked anion exchange membranes with regional intensive ion clusters prepared from quaternized branched polyethyleneimine/quaternized polysulfone, Product Details of C4H6N2, the publication is International Journal of Hydrogen Energy (2022), 47(59), 24991-25006, database is CAplus.

A series of anion exchange membranes (AEMs) with regionally dense ion clusters are prepared by crosslinking quaternized polysulfone (QPSU) with quaternized branched polyethyleneimine (QBPEI). For the as-prepared QPSU/QBPEI AEMs, the hydrophilic QBPEI forms locally aggregated ion clusters in the QPSU matrix, which can promote the formation of an obvious microphase separation structure in the membrane. The QPSU/QBPEI-3 AEM with an ion exchange capacity of 1.88 meq/g exhibits the best performance, achieving a reasonably high ionic conductivity of 66.14 mS/cm at 80°C and showing good oxidation stability and alkali resistance. Finally, the maximum power d. of a single H₂/O₂ fuel cell with QPSU/QBPEI-3 AEM reaches 75.34 mW/cm² at 80°C. The above results indicate that QBPEI with a dendritic structure and abundant anionic conductive groups has a good application prospect in the preparation of AEMs with locally aggregated ion clusters and microphase separation structures.

Cai, Dongren published the artcileDesign and synthesis of novel Bronsted-Lewis acidic ionic liquid and its application in biodiesel production from soapberry oil, Related Products of pyrazoles-derivatives, the publication is Energy Conversion and Management (2018), 318-327, database is CAplus.

With the combination of mol. simulation and relevant experiments, the efficient Bronsted-Lewis acidic ionic liquid (IL) was designed and synthesized for biodiesel production from soapberry oil. In mol. simulation, 4-methylthiazole (MT) is proved to be the best matrix for IL preparation via electrostatic potential anal. and proton affinity anal., and it also is verified by experiments In orthogonal experiment, the relationship in catalytic activity between Bronsted-Lewis acidic IL and corresponding materials (Bronsted acidic IL and metal chloride) was revealed. Meanwhile, [Ps-MTH][CF₃SO₃] and FeCl₃ are verified as the best materials for preparation of Bronsted-Lewis acidic IL, and [Ps-MTH][CF₃SO₃]-FeCl₃(x = 0.65) is determined as the most efficient catalyst in the end. The Lewis acidity, Bronsted acidity and interaction of [Ps-MTH][CF₃SO₃] and FeCl₃ in [Ps-MTH][CF₃SO₃]-FeCl₃(x = 0.65) were characterized by FT-IR. And the catalytic mechanism of transesterification catalyzed by prepared IL was clarified. In order to maximize the biodiesel yield, optimization of process variables was conducted using Box-Behnken response surface methodol. The 97.04% of high biodiesel yield is obtained under the optimum conditions: reaction temperature was 127 °C, molar ratio (methanol to soapberry oil) was 27.96:1, catalyst amount was 3.06 mmol and reaction time was 8 h. Furthermore, [Ps-MTH][CF₃SO₃]-FeCl₃(x = 0.65) presents good catalytic activity in different transesterification for biodiesel production And its catalytic activity decreases from 97.04% to 93.59% after being used for 5 times, which reflects good reusability. The main properties of soapberry biodiesel were also measured and compared to the ASTM D6751 standard
