Casalta, Clement;Gourlaouen, Christophe;Bouzbouz, Samir research published 《 Iridium(III) Catalyzed Z-Selective Allylic Arylation of α-Fluoro But-1-enoic Acid Amides via β-F-Elimination in Water》, the research content is summarized as follows. Allylic arylation of α-fluoro but-1-enoic acid amides with arylboronic acids was carried out in water by comparing the catalytic activity of iridium(III) and rhodium(III). Ir(III) has shown a strong superiority over Rh(III) to give allyl-aryl coupling products with excellent stereoselectivity in favor of the Z-isomer. The origin of high stereoselectivity is perhaps because of the a coordination of iridium Ir-N or Ir-O.

Agonism of the 5-HT_2C receptor represents one of the most well-studied and clin. proven mechanisms for pharmacol. weight reduction Selectivity over the closely related 5-HT_2A and 5-HT_2B receptors is critical as their activation has been shown to lead to undesirable side effects and major safety concerns. In this communication, we report the development of a new screening paradigm that utilizes an active site mutant D134A (D3.32) 5-HT_2C receptor to identify atypical agonist structures. We addnl. report the discovery and optimization of a novel class of nonbasic heterocyclic amide agonists of 5-HT_2C. SAR investigations around the screening hits provided a diverse set of potent agonists at 5-HT_2C with high selectivity over the related 5-HT_2A and 5-HT_2B receptor subtypes. Further optimization through replacement of the amide with a variety of five- and six-membered heterocycles led to the identification of 6-(1-ethyl-3-(quinolin-8-yl)-1H-pyrazol-5-yl)pyridazin-3-amine (69). Oral administration of 69 to rats reduced food intake in an ad libitum feeding model, which could be completely reversed by a selective 5-HT_2C antagonist.

Cardona, Maria I.;Dominguez, Gina P.;Echeverry, Sandra M.;Valderrama, Ivonne H.;Bernkop-Schnurch, Andreas;Aragon, Marcela research published 《 Enhanced oral bioavailability of rutin by a self-emulsifying drug delivery system of an extract of calyces from Physalis peruviana》, the research content is summarized as follows. The aim of this study was to develop and optimize a self-emulsifying drug delivery system (SEDDS) containing an extract of calyces from Physalis peruviana with high mucus permeating properties to increase the bioavailability and the hypoglycemic activity of the active metabolites of the extract The oil, surfactant, and co-solvent were selected based on solubility studies. The formulation was optimized using Box-Behnken statistical exptl. design (BBD). Optimized conditions were Labrafac as oil 10% (weight/weight), Solutol HS 15 as surfactant 45% (weight/weight), propylene glycol as co-solvent 32% (weight/weight) and PDMSHEPMS 13% (weight/weight). The extract was loaded into SEDDS to 45% (weight/weight). The optimized SEDDS exhibited a mean droplet size of 19.5 nm, PDI of 0.20, and neg. zeta potential. Furthermore, SEDDS permeating properties were investigated in porcine intestinal mucus using the Transwell method. Extract-loaded SEDDS showed a 2.6-fold increase in mucus permeation compared to the unformulated extract A pharmacokinetic study showed a nearly 6-fold increase in rutin oral bioavailability in comparison with the unformulated extract Moreover, the hypoglycemic activity of the extract-loaded SEDDS was higher than that of the unformulated extract These results indicate that incorporating an extract of calyces from P. peruviana into SEDDS is a promising strategy to improve the oral bioavailability of the active flavonoids in the extract and the hypoglycemic activity.

Cao, Maoyu;Li, Wenjing;Ge, Pengxiang;Chen, Mindong;Wang, Junfeng research published 《 Seasonal variations and potential sources of biomass burning tracers in particulate matter in Nanjing aerosols during 2017-2018》, the research content is summarized as follows. Biomass burning (BB) is an important source of atm. particulate matter and can adversely affect air quality, visibility, human health, and climate change. To study the characteristics and potential source regions of BB tracers in PM2.5, a liquid chromatog.-mass spectrometry instrument (HPLC-MS/MS) is applied in this study to develop and validate a method to determine organic tracers of BB in 397 aerosol samples. The total mean concentrations of 17 tracers measured in 2017 and 2018 were 333.32 ng m-3 and 243.45 ng m-3, resp. Among them, the concentration of levoglucosan was the highest among all the tracers, with 325.63 ng m-3 in 2017 and 237.47 ng m-3 in 2018. The BB tracers showed obvious seasonal variations characteristics, most of which were abundant in winter. However, the concentrations of 3,4-dimethoxyacetic acid and sinapinic acid were higher in summer and spring than that in the other seasons. There were obvious differences in the Potential Source Contribution Factor (PSCF) model results of the BB’s potential source area annually and in different seasons. The results of the potential source anal. showed that Beijing-Tianjin-Hebei had a great impact on the Nanjing air quality in 2017. Finally, five source factors for BB were identified based on the Pos. Matrix Factor (PMF) model, and these were cellulose, hardwood, softwood, grass, and secondary formed. During the 2 years, cellulose was the largest contributor to biomass burning. Owing to the different fire conditions each year, the contribution of the five factors to the BB tracers was also different. For example, the contribution of softwood to the BB tracers was greater in 2018 (8.4%) than in 2017 (5.2%), while the contributions of hardwood and cellulose did not change significantly.

530-59-6, Sinapinic acid is a chemical compound that is the dihydroxybenzoic acid derivative of sinapic acid. It has been shown to have anti-inflammatory properties in vitro and in vivo. Sinapinic acid inhibits the activity of various enzymes, such as cyclooxygenase (COX), lipoxygenase (LOX), and 5-lipoxygenase-activating protein (FLAP). It also decreases levels of adhesion molecules and downregulates inflammatory response genes. Sinapinic acid has been shown to reduce inflammation by inhibiting the formation of proinflammatory mediators, such as prostaglandin E2 or leukotriene B4, in endothelial cells and mammary epithelial cells.
Sinapic acid is a phenylpropanoid hydroxycinnamic acid with diverse biological activities. Sinapic acid inhibits collagen-induced human platelet aggregation by up to 70% in vitro (IC50 = 1.03 mM). It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) and 2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonate) (ABTS) free radicals with IC50 values of 8.3 and 5.4 μg/ml, respectively. Sinapic acid (200 μM) reduces colony formation of SW480 human colon carcinoma cells by 4-fold. It also inhibits colony formation of E. coli, S. enteritidis, and S. aureus on agar (MICs = 2.2, 2, and 1.8 mM, respectively). In vivo, sinapic acid (4 mg/kg, p.o.) increases the time spent in the open arms of the elevated plus maze by approximately 15% in mice, an effect that can be blocked by the GABAA receptor antagonists flumazenil and bicuculline. Sinapic acid is also commonly used as a matrix in protein mass spectrometry.

Caldwell, Alexander S.;Rao, Varsha V.;Golden, Alyxandra C.;Bell, Daniel J.;Grim, Joseph C.;Anseth, Kristi S. research published 《 Mesenchymal stem cell-inspired microgel scaffolds to control macrophage polarization》, the research content is summarized as follows. There is a desire in regenerative medicine to create biofunctional materials that can control and direct cell function in a precise manner. One particular stem cell of interest, human mesenchymal stem cells (hMSCs), can function as regulators of the immunogenic response and aid in tissue regeneration and wound repair. Here, a porous hydrogel scaffold assembled from microgel subunits was used to recapitulate part of this immunomodulatory behavior. The scaffolds were used to culture a macrophage cell line, while cytokines were delivered exogenously to polarize the macrophages to either a pro-inflammatory (M1) or alternatively activated (M2a) phenotypes. Using a cytokine array, interleukin 10 (IL-10) was identified as one key anti-inflammatory factor secreted by hMSCs in pro-inflammatory conditions; it was elevated (125 ± 25 pg/mL) in pro-inflammatory conditions compared to standard medium (6 ± 10 pg/mL). The ability of hMSC laden scaffolds to reverse the M1 phenotype was then examined, even in the presence of exogenous pro-inflammatory cytokines. Co-culture of M1 and M2 macrophages with hMSCs reduced the secretion of TNFα, a pro-inflammatory cytokine even in the presence of pro-inflammatory stimulatory factors. Next, IL-10 was supplemented in the medium or tethered directly to the microgel subunits; both methods limited the secretion of pro-inflammatory cytokines of encapsulated macrophages even in pro-inflammatory conditions. Cumulatively, these results reveal the potential of biofunctional microgel-based scaffolds as acellular therapies to present anti-inflammatory cytokines and control the immunogenic cascade.

Alberto;Roda, Nuria;Sanz-Cervera, Juan F. research published 《 Design, synthesis and antimalarial evaluation of novel thiazole derivatives》, the research content is summarized as follows. As part of our medicinal chem. program’s ongoing search for compounds with antimalarial activity, we prepared a series of thiazole analogs and conducted a SAR study analyzing their in vitro activities against the chloroquine-sensitive Plasmodium falciparum 3D7 strain. The results indicate that modifications of the N-aryl amide group linked to the thiazole ring are the most significant in terms of in vitro antimalarial activity, leading to compounds with high antimalarial potency and low cytotoxicity in HepG2 cell lines. Furthermore, the observed SAR implies that non-bulky, electron-withdrawing groups are preferred at the ortho position on the Ph ring, whereas small atoms such as H or F are preferred at the para position. Finally, replacement of the Ph ring by a pyridine affords a compound with similar potency, but with potentially better physicochem. properties which could constitute a new line of research for further studies.

We employ an affinity-based screen of 1013in vitro-translated macrocyclic peptides to identify high-affinity PCSK9 ligands that utilize a unique, induced-fit pocket and partially disrupt the PCSK9-LDLR interaction. Structure-based design led to mols. with enhanced function and pharmacokinetic properties (e.g., ₁₃PCSK9i). In mice, ₁₃PCSK9i reduces plasma cholesterol levels and increases hepatic LDLR d. in a dose-dependent manner. ₁₃PCSK9i functions by a unique, allosteric mechanism and is the smallest mol. identified to date with in vivo PCSK9-LDLR disruptor function.

TFF3 regulates essential gastro- and neuroprotective functions, but its mol. mode of action remains poorly understood. Synthetic intractability and lack of reliable bioassays and validated receptors are bottlenecks for mechanistic and structure-activity relationship studies. Here, we report the chem. synthesis of TFF3 and its homodimer via native chem. ligation followed by oxidative folding. Correct folding was confirmed by NMR and CD, and TFF3 and its homodimer were not cytotoxic or hemolytic. TFF3, its homodimer, and the trefoil domain (TFF3_10-50) were susceptible to gastrointestinal degradation, revealing a gut-stable metabolite (TFF3_7-54; t_1/2 > 24 h) that retained its trefoil structure and antiapoptotic bioactivity. We tried to validate the putative TFF3 receptors CXCR4 and LINGO2, but neither TFF3 nor its homodimer displayed any activity up to 10μM. The discovery of a gut-stable bioactive metabolite and reliable synthetic accessibility to TFF3 and its analogs are cornerstones for future mol. probe development and structure-activity relationship studies.

Non-small-cell lung cancer (NSCLC) is a major disease that accounts for 85% of all lung cancer cases which claimed around 1.8 billion lives worldwide in 2020. Tyrosine kinase inhibitors (TKIs) that target EGFR have been used for the treatment of NSCLC, but often develop drug resistance, and the covalent inhibitor AZD9291 (I) has been developed to tackle the problem of drug resistance mediated by the T790M EGFR mutation; however, there is a side effect of hyperglycemia that may be due to off-target activity. This study examines analogs of AZD9291 by chem. proteomics, identifying analogs that maintain T790M-EGFR engagement while showing reduced cross-reactivity with off-targets.
