And the article contained the following:

Repeated-dose toxicity (RDT) studies are one of the critical studies to assess chem. safety. There have been some studies attempting to predict RDT endpoints based on chem. substructures, but it remains very difficult to establish such a method, and a more detailed characterization of chem. compounds seems necessary. Cytochrome P450s (P450s) comprise multiple forms with different substrate specificities and play important roles in both the detoxification and metabolic activation of xenobiotics. In this study, we investigated possible use of P 450 reactivity of chem. compounds to classify the compounds A total of 148 compounds with available rat RDT test data were used as test compounds and subjected to inhibition assays against 18 human and rat P450s. Among the tested compounds, 82 compounds inhibited at least one P 450 form. Hierarchical clustering analyses using the P 450 inhibitory profiles divided the 82 compounds into nine groups, some of which showed characteristic chem. and biol. properties. Principal component analyses of the P 450 inhibition data in combination with the calculated chem. descriptors demonstrated that P 450 inhibition data were plotted differently than most chem. descriptors in the loading plots. Finally, association analyses between P 450 inhibition and RDT endpoints showed that some endpoints related to the liver, kidney and hematol. were significantly associated with the inhibition of some P450s. Our present results suggest that the P 450 reactivity profiles can be used as novel descriptors for characterizing chem. compounds for the investigation of the toxicity mechanism and/or the establishment of a toxicity prediction model. The experimental process involved the reaction of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate(cas: 3319-31-1).Quality Control of Tris(2-ethylhexyl) benzene-1,2,4-tricarboxylate

And the article contained the following:

Nearly all antibiotics are ineffective to the antibiotic-resistant bacteria New Delhi metallo-beta -lactamase-1(NDM-1), one of the most important reasons is that antibiotics can be hydrolyzed by NDM-1 in these bacteria. Up to date, Many compounds, including captopril, are found to possess NDM-1 inhibition activity. Herein we report that some cysteine derivatives or homocysteine derivatives can inhibit the NDM-1 protein, and the lead compound 9 has the inhibition of the NDM-1 protein with IC50 of 1 μM, which is about 8 times potency of captopril.

On July 31, 2014, Guo, Rongyun; Nie, Yao; Mu, Xiao Qing; Xu, Yan; Xiao, Rong published an article.Application In Synthesis of (R)-Methyl 3-hydroxybutanoate The title of the article was Genomic mining-based identification of novel stereospecific aldo-keto reductases toolbox from Candida parapsilosis for highly enantioselective reduction of carbonyl compounds. And the article contained the following:

Biocatalytic reduction of prochiral ketones offers significant potential in synthesis of optically active alcs. However, so far the application of aldo-keto reductases (AKRs) in asym. reduction has been hampered due to limited availability of AKRs with high enantioselectivity and catalytic efficiency. Based on the genome sequence of Candida parapsilosis, a versatile bioresource for asym. reduction, eight open reading frames encoding putative AKRs were discovered and expressed, and the resulted enzymes (CPARs), comprising an AKR toolbox, were evaluated toward various carbonyl substrates. The CPARs were active to the selected substrates, especially 2-hydroxyacetophenone and Et 4-chloro-3-oxobutyrate. Addnl., most of them were obviously enantioselective to the substrates and gave alc. products with optical purity up to 99% e.e. Of the enzymes, CPAR4 was outstanding with excellent enantioselectivity and broad substrate spectrum. All these pos. features demonstrate that genomic mining is powerful in searching for novel and efficient biocatalysts of desired reactions for pharmaceuticals and fine chems. synthesis. The experimental process involved the reaction of (R)-Methyl 3-hydroxybutanoate(cas: 3976-69-0).Application In Synthesis of (R)-Methyl 3-hydroxybutanoate

On July 31, 2022, Li, Huai-Ming; Li, Guan-Dong; Li, Jun-Yu; Zhang, Teng published an article.SDS of cas: 1312703-30-2 The title of the article was An Iodine-Functionalized Metal-Organic framework for catalytic alkene bromination. And the article contained the following:

An iodine-functionalized metal-organic framework (MOF), UiO-68-I, was synthesized. UiO-68-I showed good catalytic activity for dibromination of alkenes and alkynes with a low catalyst loading of 1% and was able to be recycled and recovered efficiently. Mechanistic studies suggest that UiO-68-I may trigger the formation of mol. bromine through a radical intermediate and thus accelerate the reaction. The activity and stability of UiO-68-I outperforms most earlier reports on organoiodine catalysts, showing the great potential of iodine-functionalized MOFs as recyclable heterogeneous hypervalent iodine reagents or catalysts.
