A rhodium-catalyzed carbonylative transformation of alkyl halides under low pressure of CO has been developed. This robust catalyst system allows using phenols as the carbonylative coupling partner and, meanwhile, exhibits high functional group tolerance and good chemoselectivity. Substrates even with a large steric hindrance group or multiple reaction sites can be selectively converted into the desired products in good to excellent yields. A gram-scale experiment was performed and delivered an almost quant. amount of the product. Control experiments were performed as well, and a possible reaction mechanism is proposed.

Sun, Shanshan published the artcileMetabolic interactions in bacterial co-culture accelerate phenanthrene degradation, HPLC of Formula: 86-48-6, the publication is Journal of Hazardous Materials (2021), 123825, database is CAplus and MEDLINE.

A highly effective phenanthrene (PHE)-degrading co-culture containing Rhodococcus sp. WB9 and Mycobacterium sp. WY10 was constructed and completely degraded 100 mg L^-1 PHE within 36 h, showing improved degradation rate compared to their monocultures. In the co-culture, strain WY10 played a predominant role in PHE degradation 1-hydroxy-2-naphthoic acid was an end-product of PHE degradation by strain WB9 and accumulated in the culture medium to serve as a substrate for strain WY10 growth, thereby accelerating PHE degradation In turn, strain WY10 degraded PHE and 1-hydroxy-2-naphthoic acid intracellularly to form phthalate and protocatechuate that were exported to the culture medium through efflux transporters. However, strain WY10 cannot take up extracellular phthalate due to the absence of phthalate transporters, restricting phthalate degradation and PHE mineralization. In the co-culture, phthalate and protocatechuate accumulated in the culture medium were taken up and degraded towards TCA cycle by strain WB9. Therefore, the metabolic cross-feeding of strains WB9 and WY10 accelerated PHE degradation and mineralization. These findings exhibiting the synergistic degradation of PHE in the bacterial co-culture will facilitate its bioremediation application.

Sun, Shanshan published the artcileNon-bioavailability of extracellular 1-hydroxy-2-naphthoic acid restricts the mineralization of phenanthrene by Rhodococcus sp. WB9, Product Details of C11H8O3, the publication is Science of the Total Environment (2020), 135331, database is CAplus and MEDLINE.

Rhodococcus sp. WB9, a strain isolated from polycyclic aromatic hydrocarbons contaminated soil, degraded phenanthrene (PHE, 100 mg L^-1) completely within 4 days. 18 Metabolites were identified during PHE degradation, including 5 different hydroxyphenanthrene compounds resulted from multiple routes of initial monooxygenase attack. Initial dioxygenation dominantly occurred on 3,4-C positions, followed by meta-cleavage to form 1-hydroxy-2-naphthoic acid (1H2N). More than 95.2% of 1H2N was transported to and kept in extracellular solution without further degradation However, intracellular 1H2N was converted to 1,2-naphthalenediol that was branched to produce salicylate and phthalate. Furthermore, 131 genes in strain WB9 genome were related to aromatic hydrocarbons catabolism, including the gene coding for salicylate 1-monooxygenase that catalyzed the oxidation of 1H2N to 1,2-naphthalenediol, and complete gene sets for the transformation of salicylate and phthalate toward tricarboxylic acid (TCA) cycle. Metabolic and genomic analyses reveal that strain WB9 has the ability to metabolize intracellular 1H2N to TCA cycle intermediates, but the extracellular 1H2N can’t enter the cells, restricting 1H2N bioavailability and PHE mineralization.

Sun, Shanshan published the artcileSalicylate and phthalate pathways contributed differently on phenanthrene and pyrene degradations in Mycobacterium sp. WY10, Category: alcohols-buliding-blocks, the publication is Journal of Hazardous Materials (2019), 509-518, database is CAplus and MEDLINE.

Mycobacterium sp. WY10 was a highly effective PAHs-degrading bacterium that can degrade phenanthrene (PHE, 100 mg L^-1) completely within 60 h and 83% of pyrene (PYR, 50 mg L^-1) in 72 h. In this study, ten and eleven metabolites, resp., were identified in PHE and PYR degradation cultures, and a detailed PHE and PYR metabolism maps were constructed based on the metabolic results. The strain WY10 degraded PHE and PYR with initial dioxygenation mainly on 3,4- and 4,5-carbon positions, resp. Thereafter, PYR degradation entered the PHE degradation pathway via the ortho-cleavage. It was observed that the “lower pathway” of PHE and PYR degradations were different. Based on the kinetics of residual metabolites, PHE was degraded in a dominant phthalate pathway and a minor salicylate pathway. However, both phthalate and salicylate pathways played important roles on PYR degradation The WY10 genome revealed there were fifty-three genes related to PAHs degradations, including a complete gene set for PHE and PYR degradation via the phthalate pathway. The candidate gene/ORF, BOH72_19755, encoding salicylate synthase might contribute in the salicylate pathway.

Huajiao (Zanthoxylum bungeanum maxim. and Zanthoxylum armatum DC.) is a highly prized spice in China due to its distinctive aroma and taste. The volatile organic compounds (VOCs) of eight kinds of red and green huajiao which varied according to geog. indication of P. R. China were evaluated by electronic nose (E-nose), headspace solid-phase microextraction-gas chromatog.-mass spectrometry (HS-SPME-GC-MS) and headspace-gas chromatog.-ion mobility spectrometry (HS-GC-IMS). Results showed that red huajiao emitted more terpenes, esters, and fewer alcs. than green huajiao. Partial least squares-discriminant anal. based on GC-MS and GC-IMS data was revealed a good classifying tool for huajiao from different original habitats. Four and eight aroma substances were selected as the potential markers by the variable importance in projection (VIP) variable selection method, resp. The results of the current study provide a useful basis in the huajiao aroma difference study. Addnl., a rapid huajiao aroma anal. method using GC-IMS was developed.

Wang, Xueli published the artcileEffect of amino-ternary alcohol on hydration of blend cementitious system with steel slag and granulated blast furnace slag, Recommanded Product: Triisopropanolamine, the publication is Guisuanyan Xuebao (2017), 45(2), 206-211, database is CAplus.

The influence of amino-ternary alc. (ATA) on the strength development and hydration of composited cementitious system incorporated with steel slag-granulated blast furnace slag (GBFS) was investigated. The mech. and hydration properties of steel slag-GBFS blend cementitious system in the presence of triethanolamine (TEA), triisopropanolamine (TIPA) and diethanol-isopropanolamine (DEIPA) were analyzed by mortar experiment, hydration heat release, X-ray diffraction (XRD), differential scanning calorimetry-thermogravimetry (DSC-TG) and SEM (SEM), resp. The results show that the promoting effect of ATA on the hydration of steel slag-GBFS cementitious system is related to the numbers of Me on the branched chain of ATA. A few numbers of Me can favor the strength development. The compressive strength of blend cementitious system is promoted by ATA, among which TEA leads to the maximum compressive strength at different ages. The addition of ATA can enhance the hydration of steel slag and GBFS via increasing the heat flow at early age and decreasing the content of portlandite (CH) to form a more compacted structure. The addition of ATA has a pos. effect on the strength development of composited cementitious system.

Yang, Songge published the artcileImpact of four kinds of alkanolamines on hydration of steel slag-blended cementitious materials, HPLC of Formula: 122-20-3, the publication is Construction and Building Materials (2017), 655-666, database is CAplus.

The impact on hydration of four kinds of alkanolamines (triethanolamine (TEA), triisopropanolamine (TIPA), diethanol-isopropanolamine (DEIPA) and methyldiethanolamine (MDEA)) in a steel slag cementitious system was reviewed. Isothermal calorimetry studies provided information on the hydration heat release rate and the cumulative energy released by blend cement systems. Mortar strength, quant. X-ray diffractometry, mercury intrusion pore size distribution anal., SEM and thermogravimetric anal. were used to analyze the mechanism of strength enhancement and micro-structure of hydrates that were impacted by alkanolamines. Alkanolamines prolonged the hydrated induction period in the steel slag-cement system, and enhanced the second exothermic peak of hydration at dosages of 0.01%, 0.03% and 0.05%. The second hydration rate was decreased by TEA, DEIPA and MDEA, and increased by TIPA at alkanolamine dosages of 0.1% and 0.2%. The compressive strength and non-evaporable water content were enhanced by the four types of alkanolamines (dosage of 0.03%) at 3 d, 7 d and 28 d, which allowed TEA and DEIPA to contribute to strength development and the hydration reaction over TIPA and MDEA. The CH content, porosity and pore size were decreased by alkanolamines at different ages. Alkanolamines promoted the formation of ettringite and an alumina-ferric oxide-monosulfate phase, and the C-S-H morphol. was also changed by different kinds of alkanolamines.

Zhu, Bin published the artcileStable Cocrystals and Salts of the Antineoplastic Drug Apatinib with Improved Solubility in Aqueous Solution, Computed Properties of 86-48-6, the publication is Crystal Growth & Design (2018), 18(8), 4701-4714, database is CAplus.

Apatinib (APA) belongs to the targeted antineoplastic family of drugs by inhibiting the vascular endothelial cell growth factor receptor (VEGFR-2) of tyrosine kinase. APA encounters poor aqueous solubility problems, and its therapeutic dosage form, Apatinib mesylate (ATM), is unstable and dissociates completely to APA in aqueous solution Here, we synthesized and evaluated three new cocrystals of APA with adipic acid (APA + ADA), sebacic acid (APA + SEA), and D/L-mandelic acid (APA + D/L-MA), and four new salts with succinic acid (APA + SUA-H₂O), salicylic acid (APA + SA), 1-hydroxy-2-naphthoic acid (APA + HNA), and saccharin (APA + SAC). All the solid forms were characterized by powder X-ray diffraction, IR spectroscopy, differential scanning calorimetry, and dynamic vapor sorption. The mol. components and structures were confirmed by single crystal X-ray diffraction. APA + SEA is able to overcome the instability problem and has improved solubility compared with ATM. Hence, APA + SEA has the potential to be a superior candidate for this important drug.

Tao, Xueqin published the artcileInteractions between polycyclic aromatic hydrocarbons (PAHs)-degrading strain Sphingomonas sp. GY2B and nano bamboo charcoal, Formula: C11H8O3, the publication is Desalination and Water Treatment (2021), 221-228, database is CAplus.

As the global consumption of engineered nanomaterials such as nano bamboo charcoal (NBC) steadily increases, so does the potential for their release into the environment through human activity. In this study, the aggregation and dispersion of NBC, and its effect on GY2B, a polycyclic aromatic hydrocarbons (PAHs)-degrading strain of Sphingomonas sp., were investigated. Results showed that NBC aggregation was affected by both its concentration and GY2B, while the zeta potential of NBC was mainly influenced by GY2B and less so by its concentration With the addition of NBC, the biodegradation rate of phenanthrene was enhanced while GY2B growth was inhibited initially, however, cell growth inhibition was attenuated and eliminated with NBC aggregation and sedimentation which adsorbed toxic metabolites, such as 1-hydroxy-2-naphthoic acid, eventually resulting in more favorable conditions. This work indicates that NBC has the potential to be used in environmental remediation.
