Herein, we report a strategy to construct highly efficient perfluorooctanoic acid (PFOA) adsorbents by installing synergistic electrostatic/hydrophobic sites onto porous organic polymers (POPs). The constructed model material of PAF-1-NDMB (NDMB = N,N-dimethyl-butylamine) demonstrates an exceptionally high PFOA uptake capacity over 2000 mg g^-1, which is 14.8 times enhancement compared with its parent material of PAF-1. And it is 32.0 and 24.1 times higher than benchmark materials of DFB-CDP (β-cyclodextrin (β-CD)-based polymer network) and activated carbon under the same conditions. Furthermore, PAF-1-NDMB exhibits the highest k₂ value of 24,000 g mg^-1 h^-1 among all reported PFOA sorbents. And it can remove 99.99% PFOA from 1000 ppb to <70 ppt within 2 min, which is lower than the advisory level of Environmental Protection Agency of United States. This work thus not only provides a generic approach for constructing PFOA adsorbents, but also develops POPs as a platform for PFOA capture. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Product Details of 76-83-5).

(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aliphatic organochlorides are often alkylating agents as chlorine can act as a leaving group, which can result in cellular damage.Product Details of 76-83-5

And the article was included in Bioorganic & Medicinal Chemistry Letters in 2017.Reference of 90064-48-5 This article mentions the following:

Scavenger receptor A (SRA) has been known as an immunosuppressive factor and therefore therapeutic inhibition of SRA may be potentially exploited for cancer immunotherapy. The previous work suggested that rhein may act as an inhibitor of SRA in reversing immunosuppression of SRA during T cells activation. Herein, three deconstruction analogs of rhein were further studied as inhibitors of SRA. These three compounds, particularly compound I, also known as a natural product danthron, enhanced T cells activation, indicated by increased transcriptional activation of interleukin 2 (Il2) gene, production of IL-2 protein, and proliferation of T cells. Addnl., the interaction between these compounds and SRA was studied by mol. modeling. Compound I showed a favorable binding mode with the cysteine rich domain of SRA protein compared to the other compounds Collectively, those results would provide insight for future design and development of next generation rhein derivatives as SRA inhibitors. In the experiment, the researchers used many compounds, for example, 4-Chloro-2,5-dimethoxybenzaldehyde (cas: 90064-48-5Reference of 90064-48-5).

Effect of exogenous nitric oxide on the volatile components in the petals of peony was written by Wang, Juan. And the article was included in Henong Xuebao in 2014.Recommanded Product: 3386-33-2 This article mentions the following:

To explore the effect of exogenous nitric oxide on volatile components in the petals of peony, 0.2 mmol·L^-1 nitric oxide (NO) donor sodium nitroprusside (SNP) was used to spray whole plant leaves in bud stage. SPME-GC-MS was used to determine the volatile components in petals of tree peony. Sixty-two kinds of volatile components were detected in the different blooming stages of peony and SNP treatment, including alkanes, terpenes, arenes, alcs., esters, ketones and heterocycles. Alkanes and terpenes were the most volatile components, and the most was at full bloom stage. Exogenous NO treatment reduced the types of alkanes, alcs. and early arenes at the petals of all blooming stages. There was no evident impact on the terpenes and ketones with esters wasn’t detected. NO treatment increased the alkanes content at full-bloom stage, decreased the contents of the terpenes, alcs. and arenes at the beginning bloom stage. Therefore, the type and content of volatile component were influenced by exogenous NO in petals of tree peony at different flowering stages. There was most influence at full blooming stage, followed by the beginning bloom stage. The impact on the end bloom stage was the min. This study will provide certain theor. basis for the development and utilization of peony flower. In the experiment, the researchers used many compounds, for example, 1-Chlorooctadecane (cas: 3386-33-2Recommanded Product: 3386-33-2).

Amide Effects in C-H Activation: Noncovalent Interactions with L-Shaped Ligand for meta Borylation of Aromatic Amides was written by Bisht, Ranjana;Hoque, Emdadul Md;Chattopadhyay, Buddhadeb. And the article was included in Angewandte Chemie, International Edition in 2018.SDS of cas: 1711-11-1 This article mentions the following:

Borylated aromatic amides 3-pinBC₆H_4-nX_nCONR₂ (6a–t; X = halo, CN, Ph, benzo, MeO) were prepared by meta C-H activation/borylation of amides X_nC₆H_5-nCONR₂ with B₂pin₂, catalyzed by [Ir₂(cod)₂(μ-OMe)₂]/L¹ with up to 99% regioselectivity. A new concept for the meta-selective iridium-catalyzed borylation of aromatic amides is described. It has been demonstrated that while esters gave para-borylated products, amides lead to meta borylations. For achieving high meta selectivity, an L-shaped bifunctional ligand I (L¹) has been employed and engages in an O…K noncovalent interaction with the oxygen atom of the moderately distorted amide carbonyl group. This interaction provides exceptional control for providing up to 99% selective formation of meta-borylated products.

And the article was included in Combinatorial Chemistry & High Throughput Screening in 2014.Category: chlorides-buliding-blocks This article mentions the following:

Yersinia pestis, a Gram neg. bacillus, spreads via lymphatic to lymph nodes and to all organs through the bloodstream, causing plague. Yersinia outer protein H (YopH) is one of the important effector proteins, which paralyzes lymphocytes and macrophages by dephosphorylating critical tyrosine kinases and signal transduction mols. The purpose of the study is to generate a three-dimensional (3D) pharmacophore model by using diverse sets of YopH inhibitors, which would be useful for designing of potential antitoxin. In this study, we have selected 60 biol. active inhibitors of YopH to perform Ligand based pharmacophore study to elucidate the important structural features responsible for biol. activity. Pharmacophore model demonstrated the importance of two acceptors, one hydrophobic and two aromatic features toward the biol. activity. Based on these features, different databases were screened to identify novel compounds and these ligands were subjected for docking, ADME properties and Binding energy prediction. Post docking validation was performed using mol. dynamics simulation for selected ligands to calculate the Root Mean Square Deviation (RMSD) and Root Mean Square Fluctuation (RMSF). The ligands, ASN03270114, Mol_252138, Mol_31073 and ZINC04237078 may act as inhibitors against YopH of Y. pestis.

And the article was included in Journal of Medicinal Chemistry in 2020.Application In Synthesis of 2,4-Dichlorophenylisothiocyanate This article mentions the following:

Rational designs of small-mol. inhibitors targeting protein-protein interfaces have met little success. Herein, we have designed a series of triazole derivatives with a novel scaffold to specifically intervene with the interaction of TLR8 homomerization. In multiple assays, TH1027 was identified as a highly potent and specific inhibitor of TLR8. A successful solution of the X-ray crystal structure of TLR8 in complex with TH1027 provided an in-depth mechanistic insight into its binding mode, validating that TH1027 was located between two TLR8 monomers and recognized as an unconventional pocket, thereby preventing TLR8 from activation. Further biol. evaluations showed that TH1027 dose-dependently suppressed the TLR8-mediated inflammatory responses in both human monocyte cell lines, peripheral blood mononuclear cells, and rheumatoid arthritis patient specimens, suggesting a strong therapeutic potential against autoimmune diseases. In the experiment, the researchers used many compounds, for example, 2,4-Dichlorophenylisothiocyanate (cas: 6590-96-1Application In Synthesis of 2,4-Dichlorophenylisothiocyanate).
