Brand, Yaneth M. published the artcileCombretastatin A-4: the antitubulin agent that inspired the design and synthesis of styrene and spiroisatin hybrids as promising cytotoxic, antifungal and antiviral compounds, Safety of 2-Aminobenzonitrile(Flakes or Chunks), the main research area is combretastatin A4 antitubulin antifungal antiviral agent cytotoxicity.

The design of a series of styrene and spiroisatin hybrids was based on the structure of combretastatin A-4 1. This library of 20 compounds were synthesized with the pharmacophoric units: 3,4,5-trimethoxy or/and 4-hydroxy-3-methoxy Ph moities in their structure. Thereby, the libraries of beta-nitrostyrenes 10a-10c, spiroisatin-dihydroquinolines 14a-14c, spiroisatinthiazolidinones 17a-17c and spiroisatin-nitropyrrolizidines 20a-20k were evaluated for their in vitro cytotoxic, anti-proliferative, antifungal and antiviral activities. Biol. results revealed that among these compounds, beta-nitrostyrenes 10a-10c exhibited significant cytotoxicity (HeLa and Jurkat tumor cells) and antifungal (T. mentagrophytes) activities. Moreover, the spiroisatindihydroquinoline 14a and 14c showed promising cytotoxicity (U937 cells). 14a-14c mols. were active against human herpesviruses serotypes 1 and 2 (HHV-1 and HHV-2), but only 14a and 14b were effective against dengue virus serotype 2 (DENV-2). The spiroisatin-nitropyrrolizidine 20c exhibited moderate anti-herpetic activity, while 17c spiroisatin-thiazolidinone derivative also reduced the infection of HHV-1 and DENV-2. Finally, the mol. docking showed that these kind of mols. interact with the subunit a/beta-tubulin.

Yuan, Gankun published the artcileNovel Targeted Photosensitizer as an Immunomodulator for Highly Efficient Therapy of T-Cell Acute Lymphoblastic Leukemia, Computed Properties of 91-15-6, the main research area is dasatinib zinc phthalocyanine PDT photosensitizer preparation acute lymphoblastic leukemia.

Dasatinib is a kinase-targeted drug used in the treatment of leukemia. Regrettably, it remains far from optimal medicine due to insurmountable drug resistance and side effects. Photodynamic therapy (PDT) has proven that it can induce systemic immune responses. However, conventional photosensitizers as immunomodulators produce anticancer immunities, which are inadequate to eliminate residual cancer cells. Herein, a novel compound 4 was synthesized and investigated, which introduces dasatinib and zinc(II) phthalocyanine as the targeting and photodynamic moiety, resp. Compound 4 exhibits a high affinity to CCRF-CEM cells/tumor tissues, which overexpress lymphocyte-specific protein tyrosine kinase (LCK), and preferential elimination from the body. Meanwhile, compound 4 shows excellent photocytotoxicity and tumor regression. Significantly, compound 4-induced PDT can obviously enhance immune responses, resulting in the production of more immune cells. We believe that the proposed manner is a potential strategy for the treatment of T-cell acute lymphoblastic leukemia.

Brehm, Julian published the artcileIn-depth characterization revealed polymer type and chemical content specific effects of microplastic on Dreissena bugensis, COA of Formula: C7H6N2, the main research area is proteomics microplastics chem composition Dreissena; Filter feeders; In-depth characterization; PET drinking bottles; Proteomics; Real-time valvometry.

In aquatic ecosystems, filter feeders like mussels are particularly vulnerable to microplastics (MP). However, little is known about how the polymer type and the associated properties (like additives or remaining monomers) of MP impact organisms, as the predominant type of MP used for effect studies on the organismic level are micron grade polystyrene spheres, without considering their chem. composition Therefore, we exposed the freshwater mussel Dreissena bugensis (D. bugensis) to in-depth characterized fragments in the same concentration and size range (20-120μm): recycled polyethylene terephthalate from drinking bottles, polyamide, polystyrene, polylactic acid, and mussel shell fragments as natural particle control. Real-time valvometry, used to study behavioral responses via the movement of the mussels valves, showed that mussels cannot distinguish between natural and MP particles, and therefore do not cease their filtration, as when exposed to dissolved pollutants. This unintentional ingestion led to polymer type-dependent adverse effects (activity of antioxidant enzymes and proteomic alterations), related to chems. and residual monomers found in MP. Overall, recycled PET elicited the strongest neg. effects, likely caused by anthranilamide, anthranilonitrile and butylated hydroxytoluene, contained in the fragments, which are toxic to aquatic organisms. As PET is among the most abundant MP in the environment, sublethal effects may gradually manifest at the population level, leading to irreversible ecosystem changes.

Catalyst species are an important class of materials in chem., industry, medicine and biotechnol. Also, waste recycling is an important process in green chem. and economic efficiency. Therefore, in order to recycle waste, biochar nanoparticles were prepared from chicken manure. Then, the biochar nanoparticles were magnetized under a green and environmentally friendly method. Finally, the surface of the magnetic biochar nanoparticles was modified and further they were applied as a novel support for fabrication of nickel as a homoselective and reusable catalyst in organic reactions. The structure of this organic-inorganic catalyst has been characterized by N2 adsorption-desorption isotherms, and the SEM, EDS, WDX, XRD, TGA, AAS, FT-IR and VSM techniques. This magnetically recyclable catalyst was used in the homoselective synthesis of tetrazole and pyranopyrazole derivatives This catalyst can be reused several times without significant loss of its catalytic efficiency. The heterogeneity and stability of this nanocatalyst were studied by hot filtration and the AAS technique. Also, the reused catalyst was characterized by the SEM, EDS, AAS and BET techniques.

In addition to its use for the study of biomols. in living systems, bioorthogonal chem. has emerged as a promising strategy to enable protein or drug activation in a spatially and temporally controlled manner. This study demonstrates the application of a bioorthogonal inverse electron-demand Diels-Alder (iEDDA) reaction to cleave trans-cyclooctene (TCO) and vinyl protecting groups from carboxylic acid-containing mols. The tetrazine-mediated decaging reaction proceeded under biocompatible conditions with fast reaction kinetics (<2 min). The anti-inflammatory activity of ketoprofen was successfully reinstated after decaging of the nontoxic TCO-prodrug in live macrophages. Overall, this work expands the scope of functional groups and the application of decaging reactions to a new class of drugs.

Wang, Zhengjie published the artcileDesign, synthesis and biological evaluation of novel 2,4-disubstituted quinazoline derivatives targeting H1975 cells via EGFR-PI3K signaling pathway, Computed Properties of 1885-29-6, the main research area is quinazoline preparation antiproliferation antitumor mol docking apoptosis EGFR; Antiproliferation; Cell cycle analysis; EGFR; Quinazoline.

In order to find new and highly effective anti-tumor drugs with targeted therapeutic effects, a series of novel 4-aminoquinazoline derivatives containing N-phenylacetamide structure were designed, synthesized and evaluated for antitumor activity against four human cancer cell lines (H1975, PC-3, MDA-MB-231 and MGC-803) using MTT assay. The results showed that the compound I had the most potent antiproliferative activity against H1975, PC-3, MDA-MB-231 and MGC-803 cell lines. At the same time, compound 19e could significantly inhibit the colony formation and migration of H1975 cells. Compound I also arrested the H1975 cell cycle in the G1 phase and mediated cell apoptosis, promoted the accumulation of ROS in H1975 cells. Furthermore, compound I exerted antitumor effect in vitro by reducing the expression of anti-apoptotic protein Bcl-2 and increasing the pro-apoptotic protein Bax and p53. Mechanistically, compound I could significantly decreased the phosphorylation of EGFR and its downstream protein PI3K in H1975 cells. Which indicated that compound I targeted H1975 cell via interfering with EGFR-PI3K signaling pathway. Mol. docking showed that compound I could bind into the active pocket of EGFR. Those work suggested that compound I would have remarkable implications for further design of anti-tumor agents.
