Yan, Jianwei;Zheng, Linxia;Wang, Jiangfei;Liu, Xiaomin;Hu, Youhong research published 《 Indoles Oxidative Ring-Opening/Cyclization Cascade with the 1,2-Diaminoarenes: Direct Synthesis of 2-Aryl-3-(2-aminoaryl)quinoxalines》, the research content is summarized as follows. A mild oxidative sequential tandem reaction was developed to rapidly generate 2-aryl-3-(2-aminoaryl)quinoxalines. This method exploited 2-substituted indoles as substrate to form quinoxalines in a one-pot reaction. The key to this tandem reaction was the formation of 3-iodoindoles, which underwent Kornblum-type oxidation with DMSO to generate active imine 2-substitued 3H-indol-3-ones. The active imines were captured in situ by 1,2-diaminobenzenes to construct diverse quinoxalines. The transformation can be accomplished at room temperature with excellent functional group tolerance.

Yan, Dan;Zhang, Haili;Xu, Xiao;Ren, Chunling;Han, Chao;Li, Zhongrui research published 《 Theranostic nanosystem with supramolecular self-assembly for enhanced reactive oxygen species-mediated apoptosis guided by dual-modality tumor imaging》, the research content is summarized as follows. With the development of precision medicine, visual and traceable treatments are highly desirable for cancer therapy. However, researchers and clinicians remain confused regarding where the drug distributes and location of the tumor, when the drug is released and when to irradiate the tumor, and how the drug presents antitumor activity, all of which hinders assessment of the cancer patient′s condition and formulation of a follow-up treatment scheme for clinicians. Here, a supramol. self-assembly theranostic nanosystem (MWNs) was designed for enhanced reactive oxygen species (ROS)-mediated cell apoptosis guided by dual-modality tumor imaging. Specifically, merocyanine was introduced in cyanine dye to extend its conjugated π-scaffolds, which could preferentially self-assemble into nanovesicles owing to its amphipathy. Furthermore, withaferin A (WA), used as a chemotherapeutic drug, was loaded to construct MWNs. The assembled or disassembled MWNs behaved differently in photoacoustic (PA) intensity and fluorescence signal intensity. The MWNs exhibited stronger PA signals and quenched fluorescence, which monitors their distribution and images the tumor location in vivo, while the disassembled MWNs showed weak PA signals and recovered fluorescence, indicating the release of drug and instructing the appropriate time to irradiate for photodynamic therapy (PDT). Thus, ROS generation introduced by PDT and released WA led to cell apoptosis. This intelligent nanosystem for precise cancer therapy that reveals where the tumor is, when to irradiate the tumor, and how the tumor is cured might establish the basis for biomedical applications of finely controlled platform.

Since the beginning of polymer science, understanding the influence of mech. stress on polymer chains has been a fundamental and important research topic. The detection of mechanoradicals generated by homolytic cleavage of the polymer chains in solution has been studied in many cases.

Single cell arrays provide an accurate classification of analyte cells through an image-based anal. of cellular phenotypes. Light-guided cell retrieval from a single cell array is a promising approach for the rapid and simple sorting of difficult to distinguish cells.
