Recommanded Product: 1H-Benzo[d]imidazol-2-amineIn 2021 ,《Characterization of a novel carbendazim-degrading strain Rhodococcus sp. CX-1 revealed by genome and transcriptome analyses》 was published in Science of the Total Environment. The article was written by Long, Zhengnan; Wang, Xiuguo; Wang, Yingjun; Dai, Huawei; Li, Changhao; Xue, Yongfei; Deng, Yanfei; Zhang, Houpu; Yu, Yunlong; Fang, Hua. The article contains the following contents:

The persistence and ecotoxicity of carbendazim residues pose a potential risk to environmental ecol. and human health. Here, a novel and highly efficient carbendazim-degrading bacterium Rhodococcus sp. CX-1, capable of utilizing carbendazim as its sole source of carbon and energy, was isolated from contaminated soil. The biodegradation characteristics and metabolic pathways were studied by mass spectrometry, genomic annotation, and transcriptome anal. The degradation rate of carbendazim by strain CX-1 was 3.98-9.90 mg/L/h under different conditions, and the optimum degradation conditions were 40°C and pH 7.0. The addition of carbon sources (glucose, fructose, and sucrose, 100 mg/L) could accelerate carbendazim degradation HPLC-MS/MS identification suggested that carbendazim is first hydrolyzed into 2-aminobenzimidazole and then to 2-hydroxybenzimidazole, and is ultimately mineralized to carbon dioxide. The genome of strain CX-1 contained 6,511,628 bp nucleotides, 2 linear plasmids, 2 circular plasmids, and 6437 protein coding genes. Genome annotation and transcriptome anal. indicated that carbendazim degradation may be regulated by the degradation genes harbored in the chromosome and in plasmid 2, and two different degradation pathways of carbendazim by imidazole ring cleavage or benzene ring cleavage were predicted. This study provided new insight to reveal the biodegradation mechanism of carbendazim; furthermore, strain CX-1 is a promising bioresource for carbendazim bioremediation.

Qian, Junfeng; Wu, Tingting; Shi, Jianqun; Chang, Hao; Liu, Donghui; Pan, Yichang published an article in 2021. The article was titled 《Improved CO2/CH4 separation performance of mixed-matrix membrane by adding ZIF-7-NH2 nanocrystals》, and you may find the article in Journal of Applied Polymer Science.Electric Literature of C7H7N3 The information in the text is summarized as follows:

Membrane-based technol. is an attractive alternative in terms of CO2 separation Pebax-based membranes are regarded as potential candidates for CO2 separation due to the favorable interaction between its poly(ethylene oxide) chains with CO2 mols. and inorganic fillers. However, the separation performance for CO2/CH4 mixture is still suffered from the moderate gas permeability and selectivity. To overcome this problem, in this work, amino-functionalized zeolite imidazolate framework (ZIF-7-NH2) nanocrystals were used as fillers to blend with Pebax 1657 for fabricating mixed-matrix membranes (MMMs). XRD, Brunauer-Emmett-Teller (BET), scanning electron microscope, and 1H NMR characterization indicated that ZIF-7-NH2 with the highest crystallinity was synthesized. Fourier transform IR spectroscopy, thermogravimetric anal., differential scanning calorimetry (DSC), and Young’s modulus showed that it has good interfacial interaction. Gas separation test results showed that both the CO2 permeability and CO2/CH4 selectivity of the 31 wt% ZIF-7-NH2/Pebax MMMs increased by 80 and 170%, resp. The improved performance is attributed to the addition of ZIF-7-NH2 nanocrystals and the favorable interfacial interactions between the polymer and ZIF-7-NH2 nanocrystals. Furthermore, the polyvinylidene fluoride supported hollow fiber composite membranes also exhibit the long-term stability for CO2/CH4 separation In addition to this study using 1H-Benzo[d]imidazol-2-amine, there are many other studies that have used 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Electric Literature of C7H7N3) was used in this study.

The article was titled 《Investigation of X-ray crystal structure and in vitro cytotoxicity of two Ga(III) complexes containing pyridine dicarboxylic acid derivatives and 2-aminobenzimidazole》, and you may find the article in Journal of Molecular Structure.SDS of cas: 934-32-7 The information in the text is summarized as follows:

Two new coordination complexes were synthesized using the reaction of two organic salts with gallium(III) nitrate octahydrate. The salts were prepared and used as ligand from the reaction of 2-aminobenzimidazole with pyridine-2,6-dicarboxylic acid and 4-hydroxypyridine-2,6-dicarboxylic acid, resp. All compounds were identified by spectroscopic methods and their crystal structures determined by single crystal x-ray diffraction. The investigations showed that the two complexes were isostructural. Moreover, thermal anal. was carried out to study the decomposition steps of the complexes. The inhibition properties of the compounds were studied in vitro using oxaliplatin as a standard against five cell lines including a human breast cancer, a prostate cancer, a human liver hepatocellular carcinoma, a colorectal carcinoma and a human foreskin fibroblast. The anti-proliferative activity of the complexes is similar in the majority of cell lines except for the prostate cancer cells. The most remarkable cytotoxicity effect of both complexes appeared on the human breast cancer cells. Determination of mitochondrial membrane potential and reactive oxygen species in this cell line suggested that apoptosis may be the main pathway for the death of the cells.
