Ding, Yue-He published the artcileIncreasing the Depth of Mass-Spectrometry-Based Structural Analysis of Protein Complexes through the Use of Multiple Cross-Linkers, Related Products of alcohols-buliding-blocks, the publication is Analytical Chemistry (Washington, DC, United States) (2016), 88(8), 4461-4469, database is CAplus and MEDLINE.

Chem. crosslinking of proteins coupled with mass spectrometry (CXMS) is a powerful tool to study protein folding and to map the interfaces between interacting proteins. The most commonly used cross-linkers in CXMS are BS³ and DSS, which have similar structures and generate the same linkages between pairs of lysine residues in spatial proximity. However, there are cases where no cross-linkable lysine pairs are present at certain regions of a protein or at the interface of two interacting proteins. In order to find the cross-linkers that can best complement the performance of BS³ and DSS, we tested seven addnl. cross-linkers that either have different spacer arm structures or that target different amino acids (BS²G, EGS, AMAS, GMBS, Sulfo-GMBS, EDC, and TFCS). Using BSA, aldolase, the yeast H/ACA protein complex, and E. coli 70S ribosomes, we showed that, in terms of providing structural information not obtained through the use of BS³ and DSS, EGS and Sulfo-GMBS worked better than the other cross-linkers that we tested. EGS generated a large number of cross-links not seen with the other amine-specific cross-linkers, possibly due to its hydrophilic spacer arm. We demonstrate that incorporating the cross-links contributed by the EGS and amine-sulfhydryl cross-linkers greatly increased the accuracy of Rosetta in docking the structure of the yeast H/ACA protein complex. Given the improved depth of useful information it can provide, we suggest that the multilinker CXMS approach should be used routinely when the amount of a sample permits.

The first enantioselective radical trifluoromethylation of benzylic C-H bonds has been established by a cooperative photoredox and copper catalysis system, providing straightforward access to structurally diverse benzylic trifluoromethylation products RCH(CF₃)CH₂R¹ [R = Ph, 2-phenyl-1,3-benzothiazol-6-yl, 4-cyclopropylphenyl, etc.; R¹ = H, n-Pr, 2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)ethyl, 2-chloroethyl, etc.] in good yields with excellent enantioselectivities under mild conditions. A broad substrate scope and excellent functional group compatibility were reported. Merging the cooperative photoredox catalysis with copper catalysis is essential for the reaction, where the photoredox catalysis is used for the generation of benzylic radicals from alkyl arenes alkyl arenes RCH₂CH₂R¹ through a hydrogen atom transfer process and the copper catalysis is used for the enantioselective trifluoromethylation of the benzylic radicals.

Yang, Jing published the artcileSynthesis of Nitrogen-doped Carbon Nanodots from Tri-isopropanolamine and the Application in Cell Imaging, Synthetic Route of 122-20-3, the publication is ChemistrySelect (2022), 7(27), e202201641, database is CAplus.

As an emerging nano-functional material, fluorescent carbon nanodots (CDs) have made breakthroughs in many fields. In our research, graphite-like nitrogen-doped carbon nanodots (N-CDs) with excellent down- and up-conversion fluorescent properties were synthesized by a facile one-step solvothermal method using tri-isopropanolamine (TIPA) as carbon and nitrogen sources. Mean particle diameter from 2.85 to 5.62 nm can be obtained by controlling the amount of HNO3 during synthesis. With low cytotoxicity and excellent fluorescence properties, the prepared N-CDs can well label HeLa cells, which has great potential in the field of cell imaging. This work could enrich the research on the preparation and application of N-CDs.

Kaur, Gurpreet published the artcileSubstituent effect on anthracene-based bisboronic acid glucose sensors, Application In Synthesis of 673456-16-1, the publication is Tetrahedron (2006), 62(11), 2583-2589, database is CAplus.

Earlier the authors communicated an anthracene-based bisboronic acid sensor for glucose. Aimed at understanding the substituent effect, the authors have introduced various functional groups, such as the cyano, nitro, and fluoro group on the boronic acid moiety of this glucose sensor. Fluorescent binding studies indicated that the cyano-substituted sensor has the highest affinity (K 2540 M^-1) for glucose, but the lowest selectivity (three-fold over fructose); the fluoro-substituted compound shows the lowest affinity (630 M^-1) and a modest selectivity (15-fold over fructose); and the unsubstituted one shows the highest selectivity over fructose (43-fold) and a modest affinity (1472 M^-1).

Wang, Shengzheng published the artcileScaffold diversity inspired by the natural product evodiamine: discovery of highly potent and multitargeting antitumor agents, Recommanded Product: 2-Hydroxy-4-(trifluoromethyl)benzoic acid, the publication is Journal of Medicinal Chemistry (2015), 58(16), 6678-6696, database is CAplus and MEDLINE.

A critical question in natural product-based drug discovery is how to translate the product into drug-like mols. with optimal pharmacol. properties. The generation of natural product-inspired scaffold diversity is an effective but challenging strategy to investigate the broader chem. space and identify promising drug leads. Extending the efforts to the natural product evodiamine, a diverse library containing 11 evodiamine-inspired novel scaffolds and their derivatives were designed and synthesized. Most of them showed good to excellent antitumor activity against various human cancer cell lines. In particular, 3-chloro-10-hydroxyl thio-evodiamine I showed excellent in vitro and in vivo antitumor efficacy with good tolerability and low toxicity. Antitumor mechanism and target profiling studies indicate that compound I is the first-in-class triple topoisomerase I/topoisomerase II/tubulin inhibitor. Overall, this study provided an effective strategy for natural product-based drug discovery.

Zhong, Shuting published the artcileDNA-compatible diversification of indole π-activated alcohols via a direct dehydrative coupling strategy, Quality Control of 4410-99-5, the publication is Organic Letters (2022), 24(4), 1022-1026, database is CAplus and MEDLINE.

Indole-based diversification is highly desired in the DNA-encoded chem. library construction. Herein, we present a general strategy for on-DNA synthesis of diverse C3-functionalized indole derivatives via indole π-activated alc. formation followed by direct dehydrative coupling. Highly efficient bond linkages of C-C, C-N, and C-S were achieved to fuse building blocks that are widely com. available. DNA-encoding compatibility of the method has been further demonstrated to pave an avenue for application in constructing indole-focused three-dimensional libraries.
