Sun, Xicheng published the artcileDiscovery of S-Nitrosoglutathione Reductase Inhibitors: Potential Agents for the Treatment of Asthma and Other Inflammatory Diseases, HPLC of Formula: 1208318-08-4, the main research area is nitrosoglutathione reductase inhibitor preparation asthma inflammation; GSNO; GSNOR; N6022; asthma; nitric oxide; pyrrole.

S-Nitrosoglutathione reductase (GSNOR) regulates S-nitrosothiols (SNOs) and nitric oxide (NO) in vivo through catabolism of S-nitrosoglutathione (GSNO). GSNOR and the anti-inflammatory and smooth muscle relaxant activities of SNOs, GSNO, and NO play significant roles in pulmonary, cardiovascular, and gastrointestinal function. In GSNOR knockout mice, basal airway tone is reduced and the response to challenge with bronchoconstrictors or airway allergens is attenuated. Consequently, GSNOR has emerged as an attractive therapeutic target for several clin. important human diseases. As such, small mol. inhibitors of GSNOR were developed. These GSNOR inhibitors were potent, selective, and efficacious in animal models of inflammatory disease characterized by reduced levels of GSNO and bioavailable NO. N6022, a potent and reversible GSNOR inhibitor, reduced bronchoconstriction and pulmonary inflammation in a mouse model of asthma and demonstrated an acceptable safety profile. N6022 is currently in clin. development as a potential agent for the treatment of acute asthma.

Farn, Shiou-Shiow published the artcileAntiinflammation Derived Suzuki-Coupled Fenbufens as COX-2 Inhibitors: Minilibrary Construction and Bioassay, Synthetic Route of 452-63-1, the main research area is antiinflammation Suzuki coupled fenbufen COX inhibitor minilibrary construction bioassay; COVID-19; COX-2 selectivity; biaryl; inflammasome; synergistic.

A small fenbufen library comprising 18 compounds was prepared via Suzuki Miyara coupling. The five-step preparations deliver 9-17% biphenyl compounds in total yield. These fenbufen analogs exert insignificant activity against the IL-1 release as well as inhibiting cyclooxygenase 2 considerably. Both the para-amino and para-hydroxy mono substituents display the most substantial COX-2 inhibition, particularly the latter one showing a comparable activity as celecoxib. The most COX-2 selective and bioactive disubstituted compound encompasses one electron-withdrawing Me and one electron-donating fluoro groups in one arene. COX-2 is selective but not COX-2 to bioactive compounds that contain both two electron-withdrawing groups; disubstituted analogs with both resonance-formable electron-donating dihydroxy groups display high COX-2 activity but inferior COX-2 selectivity. In silico simulation and modeling for three COX-2 active-p-fluoro, p-hydroxy and p-amino-fenbufens show a preferable docking to COX-2 than COX-1. The most stabilization by the p-hydroxy fenbufen with COX-2 predicted by theor. simulation is consistent with its prominent COX-2 inhibition resulting from experiments

Ottosen, Erik Rytter published the artcileSynthesis and structure-activity relationship of aminobenzophenones. A novel class of p38 MAP kinase inhibitors with high antiinflammatory activity, HPLC of Formula: 452-63-1, the main research area is aminobenzophenone preparation structure activity MAP kinase inhibitor antiinflammatory; skin inflammation aminobenzophenone preparation structure activity MAP kinase inhibitor; dermatitis aminobenzophenone preparation structure activity MAP kinase inhibitor antiinflammatory; human aminobenzophenone preparation structure activity MAP kinase inhibitor antiinflammatory; kinase phosphorylating MAP inhibitor aminobenzophenone preparation structure activity; tumor necrosis factor kinase MAP inhibitor aminobenzophenone preparation; interleukin tumor necrosis factor kinase MAP inhibitor aminobenzophenone preparation; inflammation inhibitor aminobenzophenone preparation structure activity p38 MAP kinase.

The synthesis and structure-activity relationship (SAR) of a series of 4-aminobenzophenones, as a novel compound class with high antiinflammatory activity, was reported. The initial lead, [4-[(2-aminophenyl)amino]phenyl](phenyl)methanone, was systematically optimized and resulted in compounds that potently inhibited the release of the proinflammatory cytokines IL-1β and TNF-α in human peripheral blood mononuclear cells stimulated by LPS. One of the most potent compounds, among others, was [4-[(2-aminophenyl)amino]-2-chlorophenyl](2-methylphenyl)methanone (I) with IC50 values of 14 and 6 nM for the inhibition of IL-1β and TNF-α, resp. Furthermore, these types of compounds were found to be potent and selective p38 MAP kinase inhibitors, e.g. I had an IC50 value of 10 nM. Mol. modeling was used to rationalize our SAR data and to propose a model for the interaction of I with the p38 MAP kinase. The model involved a favorable hydrogen bond between the carbonyl group of the benzophenone and the NH of Met-109, positioning ring A in the hydrophobic pocket I of the enzyme. Good antiinflammatory effects were demonstrated in two murine models of dermatitis after topical application (oxazolone and TPA model).

Bcr-Abl threonine 315 to isoleucine 315 (T315I) gatekeeper mutation induced drug resistance remains an unmet clin. challenge for the treatment of chronic myeloid leukemia (CML). Chem. degradation of Bcr-AblT315I protein has become a potential strategy to overcome drug resistance. Herein, we first described the design, synthesis, and evaluation of a new class of selective Bcr-AblT315I proteolysis-targeting chimeric (PROTAC) degraders based on GZD824 (reported as Bcr-AblT315I inhibitor by our group). One of the degrader 7o with 6-member carbon chain linkage with pomalidomide exhibits the most potent degradation efficacy with DR of 69.89% and 94.23% at 100 and 300 nmol/L, resp., and has an IC50 value of 26.8 ± 9.7 nmol/L against Ba/F3T315I cells. Further, 7o also displays substantial tumor regression against Ba/F3-Bcr-AblT315I xenograft model in vivo.

Murray, Michael published the artcileCarbon Chain Length Modulates MDA-MB-231 Breast Cancer Cell Killing Mechanisms by Mitochondrially Targeted Aryl-Urea Fatty Acids, Related Products of bromides-buliding-blocks, the main research area is aryl urea fatty acid preparation structure breast cancer mitochondrion; antitumor agents; apoptosis; breast cancer; fatty acids; lipid drugs.

Targeting the tumor cell mitochondrion could produce novel anticancer agents. We designed an aryl-urea fatty acid (1 g; 16({[4-chloro-3-(trifluoromethyl)phenyl]carbamoyl}amino)hexadecanoic acid) that disrupted the mitochondrion and decreased MDA-MB-231 breast cancer cell viability. To optimize the aryl-ureas the present study evaluated mitochondrial targeting by 1 g analogs containing alkyl chains between 10-17 carbons. Using the dye JC-1, the C12-C17 analogs efficiently disrupted the mitochondrial membrane potential (IC50s 3.5±1.2 to 7.6±1.1μM) and impaired ATP production; shorter analogs were less active. 7-Aminoactinomycin D/annexin V staining and flow cytometry showed that these agents activated the killing mechanisms of necrosis and apoptosis to varying extents (7-aminoactinomycin D/annexin V staining ratios 4.3-6.0). Indeed, 1 g and its C17 analog preferentially activated necrosis and apoptosis, resp. (ratios 2.1 and 16). Taken together, alkyl chain length is a determinant of mitochondrial targeting by aryl-ureas and can be varied to develop analogs that activate apoptosis or necrosis in a regulated fashion.

Wisniewski, John A. published the artcileStructure-Based Design of 1,4-Dibenzoylpiperazines as β-Catenin/B-Cell Lymphoma 9 Protein-Protein Interaction Inhibitors, Formula: C6H4BrNO3, the main research area is dibenzoylpiperazine preparation beta catenin BCL9 protein interaction inhibitor antitumor; B-cell lymphoma 9; Wnt signaling; inhibitor; protein−protein interactions; selectivity; β-Catenin.

A small-mol. inhibitor with a 1,4-dibenzoylpiperazine scaffold was designed to match the critical binding elements in the β-catenin/B-cell lymphoma 9 (BCL9) protein-protein interaction interface. Inhibitor optimization led to a potent inhibitor that can disrupt the β-catenin/BCL9 interaction and exhibit 98-fold selectivity over the β-catenin/cadherin interaction. The binding mode of new inhibitors was characterized by structure-activity relationships and site-directed mutagenesis studies. Cell-based studies demonstrated that this series of inhibitors can selectively suppress canonical Wnt signaling and inhibit growth of Wnt/β-catenin-dependent cancer cells.

Aicher, Thomas D. published the artcileDiscovery of LYC-55716: A Potent, Selective, and Orally Bioavailable Retinoic Acid Receptor-Related Orphan Receptor-γ (RORγ) Agonist for Use in Treating Cancer, Formula: C7H4BrF3O, the main research area is benzoxazine derivative oral RAR ROR receptor agonist preparation cancer.

Retinoic acid receptor-related orphan receptor γ (RORc, RORγ, or NR1F3) is the nuclear receptor master transcription factor that drives the function and development of IL-17-producing T helper cells (Th17), cytotoxic T cells (Tc17), and subsets of innate lymphoid cells. Activation of RORγ+ T cells in the tumor microenvironment is hypothesized to render immune infiltrates more effective at countering tumor growth. To test this hypothesis, a family of benzoxazines was optimized to provide LYC-55716 (37c), a potent, selective, and orally bioavailable small-mol. RORγ agonist. LYC-55716 decreases tumor growth and enhances survival in preclin. tumor models and was nominated as a clin. development candidate for evaluation in patients with solid tumors.

Eggers, Paul K. published the artcileThe Effect of Surface Polarity on the Electrochemical Double Layer and Its Influence on the Measurement of the Standard Rate Constant of Electron Transfer, COA of Formula: C15H29BrO2, the main research area is surface polarity elec double layer electron transfer kinetics; mercaptoferrocenemethylcarboxamide preparation elec double layer gold.

The influence of surface polarity and, hence, the elec. double layer on long-range electron transfer was studied using 35 different electrode constructs. These constructs were prepared using 5 different lengths of ferrocene-modified alkanethiols (of general formula HS(CH2)nCONHCH2Fc where n was 7, 10, 11, 14, and 15 and Fc refers to ferrocene) mixed with an appropriate ratio of hydroxyl-terminated to Me-terminated alkanethiols as diluents. The mixtures of diluents in different ratios served not only to sep. and dilute the redox-active species but also to control the surface polarity of the self-assembled monolayer (SAM). The ratios of the 3 components in each SAM were 1:20:0, 1:16.6:3.4, 1:13.4:6.6, 1:10:10, 1:6.6:13.4, 1:16.6:3.4, and 1:0:20 of the ferrocene-, hydroxyl-, and Me-terminated species, resp. The formal redox potential and electron transfer rate constant were measured for each construct. It was found, 1st, that formal potentials changed according to the theory of interfacial potential distribution and, 2nd, that rate constants measured using cyclic voltammetry are strongly influenced by the Stern layer of the elec. double layer, which forms at the SAM-solution interface.
