Xue, Xia;Zhang, Yingjie;Liao, Yongxiang;Sun, Deqing;Li, Lina;Liu, Ying;Wang, Yongjie;Jiang, Wen;Zhang, Jian;Luan, Yun;Zhao, Xiaogang research published 《 Design, synthesis and biological evaluation of dual HDAC and VEGFR inhibitors as multitargeted anticancer agents》, the research content is summarized as follows. Herein, a novel series of dual histone deacetylase (HDAC) and vascular endothelial growth factor receptor (VEGFR) inhibitors were designed, synthesized and biol. evaluated based on previously reported pazopanib-based HDAC and VEGFR dual inhibitors. Most target compounds showed significant HDAC1, HDAC6 and VEGFR2 inhibition, which contributed to their potent antiproliferative activities against multiple cancer cell lines and significant antiangiogenic potencies in both human umbilical vein endothelial cell (HUVEC) tube formation assays and rat thoracic aorta ring assays. Further HDAC selectivity evaluations indicated that hydroxamic acids 5 and 9e possessed HDAC isoform selectivity profiles similar to that of the approved HDAC inhibitor suberoylanilide hydroxamic acid(SAHA), while hydrazide12 presented an HDAC isoform selectivity profilesimilar to that of the clin. HDAC inhibitor MS-275. The VEGFR inhibition profiles of 5, 9e and 12 were similar to that of the approved VEGFR inhibitor pazopanib. The intracellular target engagements of Compounds 5 and 12 were confirmed by western blot anal. The metabolic stabilities of 5, 9e and 12 in mouse liver microsomes were inferior to that of pazopanib. These dual HDAC and VEGFR inhibitors provide lead compounds for further structural optimization to obtainpolypharmacol. anticancer agents.

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. The authors developed a single cell array enclosed with a photodegradable hydrogel in microwells to enable both comprehensive image-based single cell anal. and light-guided cell retrieval. In this system, individual cells became trapped in the microwells together with the photodegradable hydrogel at a high cell d. on a chip regardless of cell type, adhesiveness, and motility. Fluorescence-stained model cells and vaccinated dendritic cells were identified by microscopic imaging and then selectively released through the light-induced degradation of the cell-embedding hydrogels. The target cells were selectively retrieved with a purity of >95% from the cell mixture through rapid photorelease, and the retrieved cells grow normally. The authors′ results provide proof-of-principle that the photoresponsive microwell array serves as a versatile tool for image-based cell sorting in cellular researches and the manufacturing processes of high-performance cells.

Yamamoto, Takumi;Kato, Sota;Aoki, Daisuke;Otsuka, Hideyuki research published 《 A Diarylacetonitrile as a Molecular Probe for the Detection of Polymeric Mechanoradicals in the Bulk State through a Radical Chain-Transfer Mechanism》, the research content is summarized as follows. 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. However, the detection of mechanoradicals in the bulk is still limited owing to their high reactivity. Herein, we propose an innovative strategy to detect mechanoradicals visually and quant. using a chain-transfer agent that generates relatively stable fluorescent radicals as a mol. probe. Mechanoradicals generated by ball milling of polystyrene samples were successfully detected by using a diarylacetonitrile compound as a fluorescent mol. probe through this radical chain-transfer mechanism. This probe enables the visualization and quant. evaluation of mechanoradicals generated by polymer-chain scission.

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.
