Bae, Eun Jung published the artcilePeripheral Selective Oxadiazolylphenyl Alanine Derivatives as Tryptophan Hydroxylase 1 Inhibitors for Obesity and Fatty Liver Disease, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is oxadiazolylphenyl alanine derivative preparation TPH1 inhibitor obesity fatty liver.

Tryptophan hydroxylase 1 (TPH1) has been recently suggested as a promising therapeutic target for treating obesity and fatty liver disease. A new series of 1,2,4-oxadiazolylphenyl alanine derivatives were identified as TPH1 inhibitors. Among them, compound 23a was the most active in vitro, with an IC50 (half-maximal inhibitory concentration) value of 42 nM, showed good liver microsomal stability, and showed no significant inhibition of CYP and hERG. Compound 23a inhibited TPH1 in the peripheral tissue with limited BBB penetration. In high-fat diet-fed mice, 23a reduced body weight gain, body fat, and hepatic lipid accumulation. Also, 23a improved glucose intolerance and energy expenditure. Taken together, compound 23a shows promise as a therapeutic agent for the treatment of obesity and fatty liver diseases.

Alqahtani, Mona A. published the artcileBio fabrication of silver nanoparticles with antibacterial and cytotoxic abilities using lichens, Related Products of isoquinoline, the main research area is silver nanoparticle antibacterial cytotoxic lichen biofabrication.

Recently, increase bacterial resistance to antimicrobial compounds issue constitutes a real threat to human health. One of the useful materials for bacterial control is Silver nanoparticles (AgNPs). Researchers tend to use biogenic agents to synthesize stable and safe AgNPs. The principal aim of this study was to investigate the ability of lichen in AgNPs formation and to find out their suppression ability to MDR bacteria as well as their cytotoxic activity. In the current study, lichens (Xanthoria parietina, Flavopunctelia flaventior) were collected from the south of the Kingdom of Saudi Arabia. Lichens methanolic extracts were used for conversion of Ag ions to AgNPs. Prepared biogenic AgNPs were characterized by UV-Visible (UV-Vis) Spectroscopy, Transmission electron microscopy (TEM), Dynamic Light Scattering (DLS) and Zeta potential and Energy-Dispersive X-ray Spectroscopy (EDS). Lichens Secondary metabolites were determined by Fourier-Transform IR Spectroscopy (FTIR) and Gas Chromatog.-Mass Spectrometry (GC-MS). The antibacterial activity and synergistic effect of AgNPs were evaluated against pathogenic bacteria, including gram-pos.; Methicillin-resistant Staphylococcus aureus (MRSA), Vancomycin-resistant Enterococcus (VRE), and gram-neg.; (Pseudomonas aeruginosa, Escherichia coli) as well as the reference strains (ATCC) using the agar disk diffusion method. Cytotoxic effect of biogenic AgNPs was tested against HCT 116 (Human Colorectal Cancer cell), MDA-MB-231 (Breast cancer cell), and FaDu (Pharynx cancer cell) by MTT test. TEM imaging showed well-dispersed spherical particles of 1-40 nm size as well as zeta size showed 69-145 nm. Furthermore, FTIR and GC-MS identified various lichen chem. mols. On the other hand, the highest antibacterial activity of AgNPs was noticed against P. aeruginosa, followed by MRSA, VRE, and E. coli. AgNPs influence on gram-neg. bacteria was greater than that on gram-pos. bacteria and their synergistic effect with some antibiotics was noted against examined microbes. Moreover, higher cytotoxicity for biogenic AgNPs against FaDu and HCT 116 cell line in relation to MDA-MB-231 was noted. Given the current findings, the biogenic AgNPs mediated by lichens had pos. antibacterial, synergistic and cytotoxic powers. Therefore, they might be considered as a promising candidate to combat the multi-drug resistance organisms and some cancer cells.

Fabbri, D. published the artcileIodinated x-ray contrast agents: Photoinduced transformation and monitoring in surface water, Recommanded Product: Diatrizoic Acid, the main research area is iodinated Xray contrast agent photoinduced transformation monitoring surface water; HRMS; TiO(2); X-ray contrast agents; transformation products; wastewater.

Conventional wastewater treatment methods have shown to be unsuitable for a complete elimination of iodinated x-ray contrast agents (ICMs), which have thus been found in wastewater treatment plant (WWTP) effluent and in surface water. Once in the surface water, they could be transformed through different processes and form several transformation products that may need to be monitored as well. We studied the abatement and transformation of ICMs by combining laboratory experiments with in field analyses. We irradiated different aqueous solutions of the selected pollutants in the presence of TiO2 as photocatalyst, aimed to promote ICMs degradation and to generate photoinduced transformation products (TPs) similar to those occurring in the environment and effluent wastewater. This exptl. strategy was applied to the study of iopromide, iopamidol and diatrizoate. A total of 24, 10, and 10 TPs were detected from iopamidol, diatrizoate and iopromide, resp. The analyses were performed using a liquid chromatog.-LTQ-FT-Orbitrap mass spectrometer. The mineralization process and acute toxicity evolution were assessed as well over time and revealed a lack of mineralization for all ICMs and the formation of harmful byproducts. After characterizing these transformation products, WWTP effluent and surface water taken from several branches of the Chicago River were analyzed for ICMs and their TPs. HRMS with MS/MS fragmentation was used as a confirmatory step for proper identification of compounds in water and wastewater samples. All 3 ICMs were detected in the effluent and surface water samples, while no significant amount of TPs were detected.

The diverse nature of Alzheimer’s disease (AD) has prompted researchers to develop multi-functional agents. Synthesized mol. hybrids of 2-pyridylpiperazine and 5-phenyl-1,3,4-oxadiazoles I (R = H, 3-Me, 2,4-dihydroxy, 3,4,5-trimethoxy, etc.) were designed. Biol. activities of synthesized compounds suggested significant and balanced inhibitory potential against target enzymes. In particular, compound I (R = 2,4-difluoro (A)) containing 2,4-difluoro substitution at terminal Ph ring considered as most potential lead with inhibition of acetylcholinesterase (hAChE, IC50 = 0.054 μM), butyrylcholinesterase (hBChE, IC50 = 0.787 μM) and beta-secretase-1 (hBACE-1, IC50 = 0.098 μM). The enzyme kinetics study of (A) against hAChE suggested a mixed type of inhibition (Ki = 0.030 μM). Also, I (R = 4-bromo) and (A) showed significant displacement of propidium iodide from the peripheral anionic site (PAS) of hAChE, excellent blood-brain barrier (BBB) permeability in parallel artificial membrane permeation assay (PAMPA), and neuroprotective ability against SH-SY5Y neuroblastoma cell lines. Further, (A) also exhibited anti-Aβ aggregation activity in self- and AChE-induced thioflavin T assay, which was ascertained by morphol. characterization by at. force microscopy (AFM). Moreover, in vivo behavioral studies signified learning and memory improvement by compound (A) in scopolamine- and Aβ-induced cognitive dysfunctions performed on Y-maze and Morris water maze. The ex vivo studies suggested decreased AChE activity and antioxidant potential of compound (A), with good oral absorption characteristics ascertained by pharmacokinetic studies.

Fu, Xufeng published the artcileDi-(2-ethylhexyl) phthalate exposure induces female reproductive toxicity and alters the intestinal microbiota community structure and fecal metabolite profile in mice, Application In Synthesis of 104-01-8, the main research area is DEHP reproductive toxicity intestinal microbiota community fecal metabolite; DEHP; female reproductive toxicity; intestinal microbiota; metabolite profile.

Di-(2-ethylhexyl) phthalate (DEHP) is one of the most commonly used plasticizers, and it is widely applied in various plastic products. DEHP is an endocrine-disrupting chem. (EDC) that has been shown to disrupt the function of reproductive system in females. Although many studies have shown that DEHP potentially causes female reproductive toxicity, including depletion of the primordial follicle and decreased sex hormone production, the specific mechanisms by which DEHP affects female reproduction remain unknown. In recent years, research focused on the intestinal flora has provided an idea to eliminate our confusion, and gut bacterial dysbiosis may contribute to female reproductive toxicity. In the present study, the feces of DEHP-exposed mice were collected and analyzed using 16S rRNA amplicon sequencing and untargeted global metabolite profiling of metabolomics. DEHP obviously causes reproductive toxicity, including the ovarian organ coefficient, estradiol level, histol. features of the ovary and estrus. Furthermore, DEHP exposure alters the structure of the intestinal microbiota community and fecal metabolite profile in mice, suggesting that the reproductive toxicity may be caused by gut bacterial dysbiosis and altered metabolites, such as changes in the levels of short-chain fatty acid (SCFA). Addnl., it is well known that changes in gut microbiota and fecal metabolites cause inflammation and tissue oxidative stress, expectedly, we found oxidative stress in the ovary and systemic inflammation in DEHP exposed mice. Thus, based on our findings, DEHP exposure may cause gut bacterial dysbiosis and altered metabolite profiles, particularly SCFA profiles, leading to oxidative stress in the ovary and systemic inflammation to ultimately induce female reproductive toxicity.

Singh, Sanjay published the artcileDevelopment of Transition-Metal-Free Lewis Acid-Initiated Double Arylation of Aldehyde: A Facile Approach Towards the Total Synthesis of Anti-Breast-Cancer Agent, Computed Properties of 151-10-0, the main research area is triarylmethane preparation; aldehyde arene double hydroarylation Lewis acid catalysis; Lewis acid-catalysis; anti-breast cancer agents; double hydroarylation; symmetrical di/tri-arylmethanes; unsymmetrical di/tri-arylmethanes.

This work describes a mild and robust double hydroarylation strategy for the synthesis of sym. /unsym. diaryl- and triarylmethanes in excellent yields using Lambert salt (0.2-1.0 mol%). Despite the anticipated challenges associated with controlling selective product formation, unsym. diaryl- and triarylmethanes products are obtained unprecedentedly. A highly efficient gram scale reaction has also been reported (TON for sym. product=475 and for unsym. product=390). The synthetic utility of the methodol. is demonstrated by the preparation of several unexplored diaryl- and triarylmethane-based biol. relevant mols., such as arundine, vibrindole A, turbomycin B, and certain anti-inflammatory agents. A total synthesis of an anti-breast-cancer agent is also demonstrated. Control experiments, Hammett anal., HRMS and GC-MS studies reveal the reaction intermediates and reaction mechanism.

Zhang, Yan published the artcileCharacterization of liquefied products from corn stalk in the presence of polyhydric alcohols with acid catalysis, Product Details of C2H6N2O, the main research area is polyhydric alc acid catalysis liquefied product corn stalk.

Atm. liquefaction technol. has been used widely and is an effective way of biomass component utilization. In this paper, the liquefied products obtained from corn stalk using polyhydric alcs. 1,2-propanediol (PG) mixed diethylene glycol (DEG) through acid catalysis under atm. pressure were characterized by various anal. technologies. The results indicated that 39 kinds of organic compounds were present in bio-oil, among which alcs. were the most, phenols were the second, and their relative contents were 70.7% and 25.6%, resp. There were also some organic acids, ethers, esters, and ketones. More than 80% of these compounds had a carbon number less than 25. Carbon NMR spectra (13C-NMR) showed that different chem. shifts δ (ppm) corresponded to various carbon types. The chem. composition of the residue from liquefaction was complex and contained a certain amount of large mol. substances that were difficult to degrade. It required more severe pyrolysis conditions than those of corn stalk. Results from X-Ray Diffraction (XRD) indicated the destruction of crystalline structure of carbohydrates and the cellulose mols. were cracked, indicating that the cellulose was degraded and the degree of liquefaction was high.
