Structure-based design and discovery of novel neuroimmunophilin FK506-binding protein (FKBP) ligands were pursued in the present study. The binding mode of the known FKBP ligand, 3-(3-pyridyl)-1-propyl- (2S)-1-(3,3-dimethyl-1,2-dioxopentyl)-2-pyrrolidinecarboxylate, in a complex with FKBP12 was investigated using LUDI simulation and upon which a novel scaffold structure predicted to possess improved binding affinity was designed. A virtual combinatorial library composed of diverse combinations of two substituted groups was constructed using Project Library, followed by an automated screening of the library against the ligand binding site on FKBP52 using DOCK. Forty-three candidate compounds I [R¹ = Me₃C, EtCMe₂, cyclopentyl, cyclohexyl, n-hexyl, n-octyl, Ph, 4-ClC₆H₄, 2,4,6-Me₃C₆H₂, PhCMe₂CH₂; R² = 3-(3-pyridyl)-1-Pr, Ph(CH₂)₃, H₂C:CH(CH₂)₈, etc.] that displayed favorable binding with the receptor were identified and synthesized. The neurotrophic activity of the candidate compounds was evaluated on chick dorsal root ganglion cultures in vitro. As a result, 15 compounds exhibited pos. effects on ganglion neurite outgrowth in the presence of 0.15 ng/mL NGF, among which 7 compounds at testing concentrations of 1 pM and 100 pM showed greater efficacy than 1 at 100 pM. I [R¹ = Me₃C; R² = 3-(3-pyridyl)-1-propyl; (II)] afforded the most potent effect in promoting the processes of neurite outgrowth and which was in a concentration-dependent manner from 1 pM to 100 pM. Half-maximal effect occurred at about 10 pM. Moreover, II at a dosage of 10 mg/kg was found to be significantly neuroprotective in a mouse peripheral sympathetic nerve injury model induced by 8 mg/kg 6-hydroxydopamine. This study further suggests the clin. potential of novel FKBP ligands as a new therapeutic approach in the treatment of neurodegenerative disorders, such as Parkinson’s disease.

Chung, Shu-Ting published the artcileSynthesis and anti-inflammatory activities of 4H-chromene and chromeno[2,3-b]pyridine derivatives, SDS of cas: 27292-49-5, the publication is Research on Chemical Intermediates (2016), 42(2), 1195-1215, database is CAplus.

Several derivatives of 4H-chromene and chromeno[2,3-b]pyridine were efficiently prepared under microwave irradiation in a one-pot reaction, and their anti-inflammatory activities were evaluated. Six synthetic products (1b, 1c, 1h, 2d, 2j, and 2l) exhibited more powerfully inhibited the production of tumor necrosis factor-α-induced nitric oxide (NO) than quercetin and exhibited comparable cell viability in both human and porcine chondrocytes. In particular, 2d at dosages of 10 and 20 mg/kg had a very potent anti-inflammatory effect by suppressing the formation of carrageenan-induced rat paw edema and prostaglandin E₂. The results herein suggest that these compounds may have potential as structural templates in the design and development of new anti-inflammatory drugs.

Luo, Xue published the artcileElectromagnetic field exposure-induced depression features could be alleviated by heat acclimation based on remodeling the gut microbiota, SDS of cas: 621-37-4, the publication is Ecotoxicology and Environmental Safety (2021), 112980, database is CAplus and MEDLINE.

Electromagnetic pollution cannot be ignored. Long-term low-dose electromagnetic field (EMF) exposure can cause central nervous system dysfunction without effective prevention. Male C57BL/6J mice (6-8 wk, 17-20 g) were used in this study. Depression-like and anxiety-like behaviors detected by behavioral experiments were compared among different treatments. 16S rRNA gene sequencing and non-targeted liquid chromatog.-mass spectrometry (LC-MS) metabolomics were used to explore the relationship between EMF exposure and heat acclimation (HA) effects on gut microbes and serum metabolites. Both EMF and HA regulated the proportions of p_Firmicutes and p_Bacteroidota. EMF exposure caused the proportions of 6 kinds of bacteria, such as g_Butyricicoccus and g_Anaerotruncus, to change significantly (p < 0.05). HA restored the balance of gut microbes that was affected by EMF exposure and the proportion of probiotics (g_Lactobacillus) increased significantly (p < 0.01). Serum metabolite anal. suggested that HA alleviated the disturbance of serum metabolites (such as cholesterol and -mannose) induced by EMF exposure. Both the metabolic KEGG pathways and PICRUSt functional anal. demonstrated that tryptophan metabolism, pyrimidine metabolism and amino acid biosynthesis were involved. EMF exposure not only led to depression-like neurobehavioral disorders, but also to gut microbiota imbalance. HA alleviated the depression features caused by EMF exposure. Based on the anal. of gut microbiota associated with serum metabolites, we speculated that gut microbiota might play a vital role in the cross-tolerance provided by HA.

Wang, Chongyang published the artcileAbsence of the nahG-like gene caused the syntrophic interaction between Marinobacter and other microbes in PAH-degrading process, Recommanded Product: 1-Hydroxy-2-naphthoic acid, the publication is Journal of Hazardous Materials (2020), 121387, database is CAplus and MEDLINE.

In this study, Marinobacter sp. N4 isolated from the halophilic consortium CY-1 was found to degrade phenanthrene as a sole carbon source with the accumulation of 1-Hydroxy-2-naphthoic acid (1H2N). With the assistance of Halomonas sp. G29, phenanthrene could be completely mineralized. The hpah1 and hpah2 gene cluster was amplified from the genome of strain N4, that were responsible for upstream and downstream of PAH degradation Strain N4 was predicted for the transformation from phenanthrene to 1H2N, and strain G29 could transform the produced 1H2N into 1,2-dihydroxynaphthalene (1,2-DHN). The produced 1,2-DHN could be further transformed into salicylic acid (SALA) by strain N4. SALA could be catalyzed into catechol by strain G29 and further utilized by strains N4 and G29 via the catechol 2,3-dioxygenase pathway and catechol 1,2-dioxygenase pathway, resp. NahG, encoding salicylate hydroxylase, was absent from the hpah2 gene cluster and predicted to be the reason for 1H2N accumulation in the PAH-degrading process by pure culture of strain N4. The syntrophic interaction mode among Marinobacter and other microbes was also predicted. According to our knowledge, this is the first report of the PAH-degrading gene cluster in Marinobacter and the syntrophic interaction between Marinobacter and other microbes in the PAH-degrading process.

Yan, Kaili published the artcileElectrosynthesis of amino acids from biomass-derived α-hydroxyl acids, Related Products of alcohols-buliding-blocks, the publication is Green Chemistry (2022), 24(13), 5320-5325, database is CAplus.

Electrochem. conversion of biomass-derived intermediate compounds to high-value products has emerged as a promising approach in the field of biorefinery. Biomass upgrading allows for the production of chems. from non-fossil-based carbon sources and capitalization on electricity as a green energy input. Amino acids, as products of biomass upgrading, have received relatively little attention. Pharmaceutical and food industries will benefit from an alternative strategy for the production of amino acids that does not rely on inefficient fermentation processes. The use of renewable biomass resources as starting materials makes this proposed strategy more desirable. Herein, we report an electrochem. approach for the selective oxidation of biomass-derived α-hydroxyl acids to α-keto acids, followed by electrochem. reductive amination to yield amino acids as the final products. Such a strategy takes advantage of both reactions at the anode and cathode and produces amino acids under ambient conditions with high energy efficiency. A flow electrolyzer was also successfully employed for the conversion of α-hydroxyl acids to amino acids, highlighting its great potential for large-scale application.

Westphal, Matthias V. published the artcileWater-compatible cycloadditions of oligonucleotide-conjugated strained allenes for DNA-encoded library synthesis, COA of Formula: C10H9NO, the publication is Journal of the American Chemical Society (2020), 142(17), 7776-7782, database is CAplus and MEDLINE.

DNA-encoded libraries of small mols. are being explored extensively for the identification of binders in early drug-discovery efforts. Combinatorial syntheses of such libraries require water- and DNA-compatible reactions, and the paucity of these reactions currently limit the chem. features of resulting barcoded products. The present work introduces strain-promoted cycloadditions of cyclic allenes under mild conditions to DNA-encoded library synthesis. Owing to distinct cycloaddition modes of these reactive intermediates with activated olefins, 1,3-dipoles, and dienes, the process generates diverse mol. architectures from a single precursor. The resulting DNA-barcoded compounds exhibit unprecedented ring and topog. features, related to elements found to be powerful in phenotypic screening.

Elbehery, Huda H. published the artcileCinnamon essential oil loaded β-cyclodextrin/gum Arabic nanoparticles affecting life table parameters of potato tuber moth, Phthorimaea operculella (Zeller), Quality Control of 106-25-2, the publication is Biocatalysis and Agricultural Biotechnology (2022), 102349, database is CAplus.

Plant essential oils are considered potential natural alternatives to chem. insecticides. However, increased degradation and evaporation of essential oils on exposure to environmental conditions may affect the bioavailability of their phytocompounds and reduce their activity as bio-insecticides. Therefore, this study aimed to formulate nanocapsules of cinnamon essential oil (CEO) by lyophilization technique using mixtures of β-cyclodextrin and gum Arabic (βCD + GA) inclusion as coating materials. By measuring life table parameters, the dry nano-formulations of CEO-βCD/GA were tested for insecticidal activity against the potato tuber moth Phthorimaea operculella (Zeller). Gas Chromatog.-Mass Spectrometry anal. of CEO identified cinnamaldehyde as the major volatile, followed by benzyl alc. with eugenol and nerol detected as minor constituents. CEO-βCD/GA particle sizes were 164.43 ± 1.27 nm and 151.36 ± 1.24 nm, with PDI values of 0.11 ± 0.00 and 0.25 ± 0.00 for 5.0 and 2.5% concentration, resp. High percentage of encapsulation efficiency was obtained, reaching 81.53 ± 0.39 and 87.39 ± 0.31 for CEO-βCD/GA at concentrations of 2.5 and 5.0%, resp. Higher mortality rates occurred in larvae treated with 2.5 and 5.0% CEO-βCD/GA (80, 85%, resp.) compared with 45% and 65% mortality rates recorded for 2.5 and 5.0% pure CEO, resp. When compared to pure CEO, CEO-βCD/GA had a significant neg. impact on tested population parameters of life table. Our findings revealed that nanoencapsulation of CEO by loading with βCD + GA inclusion increased its insecticidal efficacy. CEO-βCD/GA nanocapsules could be effective in P. operculella integrated pest management program.

Wang, TsingHai published the artcileImpact of microporous structures of esterified cellulose filter papers on Co (II) rejection in cross-flow microfiltration, Formula: C8H8O3, the publication is Separation and Purification Technology (2021), 119738, database is CAplus.

The Donnan exclusion effect is a unique phenomenon in which ions are electrostatically repelled by a surface bearing an identical charge. In this study, cellulose filter papers were esterified by ten different organic acids to systematically evaluate how surface properties regulate the development of the Donnan exclusion effect and subsequent Co(II) rejection. Among the esterified cellulose filter papers, those exhibiting high Co(II) rejection (>80% in 1.0 mg/L Co(II) in 1.0 mM NaCl background electrolyte solution) were noted to simultaneously possess pos. zeta potential when in contact with Co(II), low adsorption affinity, and a relatively high microporous environment. This behavior could be explained by the Gouy-Chapman-Stern (GCS) model, in which the ion retention in the overlapped elec. double layers (EDLs) regulates the zeta potential development and consequently the Co(II) rejection. In addition to introducing reactive carbonyl and carboxyl groups, we suggest that the creation of a relatively microporous environment is essential for high Co(II) rejection. Our results are valuable for developing low-energy filtration systems for environmentally friendly water and wastewater treatment.

Liu, Caiyun published the artcileBinding Modes of Salicylic Acids to Titanium Oxide Molecular Surfaces, HPLC of Formula: 86-48-6, the publication is Chemistry – A European Journal (2020), 26(12), 2666-2674, database is CAplus and MEDLINE.

A set of titanium oxide clusters (TOCs) comprised of 4 to 16 Ti atoms are synthesized with substituted salicylates (SSAs). The interfacial coordination environment of these SSA/Ti oxide hybrids are surveyed and found to be limited to four binding modes, with the bridging chelate mode being the most common one. The SSA-functionalized TOCs show strong visible light absorption properties. The contribution of the SSAs in the frontier orbitals of the TOCs are analyzed by using TD-DFT calculations based on the mol. geometries determined by X-ray diffraction. For TOCs of relatively high O/Ti ratio, the SSAs narrow the band gap of the TOCs by contributing solely to the HOMOs. Both binding modes and locations of the SSAs are important for the roles of SSAs in changing the HOMOs and thereby the absorption onsets.

Luo, Chengyi published the artcileEfficient biodegradation of phenanthrene using Pseudomonas stutzeri LSH-PAH1 with the addition of sophorolipids: Alleviation of biotoxicity and cometabolism studies, Formula: C11H8O3, the publication is Environmental Pollution (Oxford, United Kingdom) (2022), 119011, database is CAplus and MEDLINE.

Phenanthrene (PHE) is widely distributed, and it can cause genotoxicity in humans by interacting with enzymes in the body. A current challenge for PHE bioremediation is the inhibitory effect of biotoxic intermediates on bacterial growth. Notably, the aerobic biotransformation processes for PHE in the presence of sophorolipids have been poorly studied. Here, a PHE-degrading strain was isolated from sediments and identified as Pseudomonas stutzeri and named LSH-PAH1. It was observed that 1-naphthol (a biotoxic substance that can inhibit strain growth) was produced during the PHE metabolism process of LSH-PAH1. The biodegradation ratio increased from 21.4% to 91.7% within 48 h after the addition of sophorolipids. Unexpectedly, this addition accelerated the metabolic process for 1-naphthol rather than causing its accumulation. The cometabolism of 1-naphthol and sophorolipids alleviated the biotoxic effects for the strain, which was verified by gene expression anal. We identified a new PHE-degrading strain and provided a mechanism for PHE biodegradation using LSH-PAH1 with the addition of sophorolipids, which provides a reference for practical applications of the bioremediation of PHE and study of the cometabolism of biotoxic intermediates.
