Ethyl bromopyruvate is used in a synthesis of thioxothiazolidines from carbon disulfide and primary amines.

Ethyl bromopyruvate is a chemical inhibitor that inhibits the enzyme pyruvate dehydrogenase, which is responsible for the conversion of pyruvic acid to acetyl-CoA. This inhibition leads to a decrease in ATP levels and can cause metabolic disorders. Ethyl bromopyruvate is used as an anthelmintic drug and in asymmetric synthesis. It is also used in the synthesis of thiostrepton, an antibiotic that has been shown to have antimicrobial activity against Gram-positive bacteria, including Staphylococcus aureus and Streptococcus pneumoniae., 70-23-5.

Hu, Lijun;Ren, Qiang;Deng, Liming;Zhou, Zongtao;Cai, Zongyu;Wang, Bin;Li, Zheng research published �Design, synthesis, and biological studies of novel 3-benzamidobenzoic acid derivatives as farnesoid X receptor partial agonist� the research content is summarized as follows. Farnesoid X receptor (FXR), a bile acid-activated nuclear receptor, regulates the metabolism of bile acid and lipids as well as maintains the stability of internal environment. FXR was considered as a therapeutic target of liver disorders, such as drug-induced liver injury, fatty liver and cholestasis. The previous reported FXR partial agonist I was a suitable lead compound in terms of its high potent and low mol. size, while the docking study of compound I suggested a large unoccupied hydrophobic pocket, which might be provided more possibility of structure-activity relationship (SAR) study. In this study, we have performed comprehensive SAR and mol. modeling studies based on lead compound I. All of these efforts resulted in the identification of a novel series of FXR partial agonists. In this series, compound II revealed the best activity and strong interaction with binding pocket of FXR. Moreover, compound II protected mice against acetaminophen-induced hepatotoxicity by the regulation of FXR-related gene expression and improving antioxidant capacity. In summary, these results suggest that compound II is a promising FXR partial agonist suitable for further investigation.

Both complexes showed strong antitumor abilities against the colon cancer cell line (HCT116) and low cytotoxicity against the normal liver cell line (L-02). The DNA binding affinity was evaluated using CD and fluorescence spectroscopy, and the Ksv and Kapp values were further quantified, revealing that the complexes bound to DNA in the intercalation mode, and caused oxidative damage to pBR322 DNA. Furthermore, complex 1 interfered with the steady-state balance of redox and Ca2+ in HCT116 cells, as well as induced cell mitochondrial membrane potential (Δψm) collapse, ATP dissipation, ultimately arrested the cell cycle in G2 phase and induced cell apoptosis. Further exploration demonstrated that the production of reactive oxygen species (ROS) might be the major contributors to the apoptotic death of HCT116 cells.

Hu, Chaolei;Xu, Wenjing;Conrads, Christian Martin;Wu, Jingnan;Pich, Andrij research published �Visible light and temperature dual-responsive microgels by crosslinking of spiropyran modified prepolymers� the research content is summarized as follows. Light-responsive microgels are interesting colloidal systems with potential applications in the biotechnol. and medicine. However, synthesis of light-responsive microgels with high loading of photoswitchable mols. is still very challenging. Herein we developed a new method to synthesize light and temperature dual-responsive spiropyran-modified poly(N-vinylcaprolactam) microgels. The novel and straightforward microgels synthesis route involved: a) synthesis of poly(N-vinylcaprolactam-co-vinylformamide) copolymers via RAFT polymerization followed by the hydrolysis to obtain primary amine groups, b) attachment of carboxyl-modified spiropyran mols. to polymer chains via coupling, and c) crosslinking of spiropyran-modified polymer chains in W/O miniemulsion to form microgels. Via this method, we successfully synthesized poly(N-vinylcaprolactam) microgels containing more than 10 mol% spiropyran. The reversible light responsiveness of the spiropyran-modified copolymers and microgels in aqueous solution, which originates from the spiropyran photoisomerization under irradiation with different wavelengths, was demonstrated by UV-Vis spectroscopy. Spiropyran-modified copolymers demonstrate shift of the lower critical solution temperature (LCST) due to the polarity change of spiropyran mols. under dark, UV and visible light. Surprisingly, dynamic light scattering (DLS) results show that the microgels based on the same copolymers are less affected by UV irradiation Microgels are swollen in darkness when spiropyran mols. are in the polar, merocyanine form, and collapse after irradiation with visible light, due to the transformation of spiropyran to the relatively nonpolar, closed spirocyclic form. In addition, the spiropyran-modified microgels exhibit reversible temperature responsiveness by presenting a volume phase transition in water from a swollen state to a collapsed state with increasing temperature and the transition temperature decreased compared to the pristine microgels due to the hydrophobicity of spiropyran units.

The synthetic nature of this molecule makes it an attractive target for analytical methods such as nuclear magnetic resonance spectroscopy. This molecule also shows significant cytotoxicity against cancer cell lines in vitro, as well as inducing tumor necrosis factor-alpha (TNF-α) production in lps-stimulated murine macrophages., Product Details of C7H6Br2

Stephen K. research published �Gold-Catalyzed [5,5]-Rearrangement� the research content is summarized as follows. A highly efficient gold-catalyzed cycloisomerization of 1,5-diynes to afford indeno[1,2-c]furans I [R = n-pentyl, Ph, 4-ClC6H4, etc.; R1 = H, 6-OMe 5-F, etc.; R2 = 4-MeC6H4, 2-IC6H4CH2, 3-I-4-MeC6H3, etc.] was developed. Various functional groups were tolerated under the mild reaction conditions, which provided an alternative approach for the synthesis of compounds I. On the basis of mechanistic studies, including crossover experiments, deuterium labeling and computational chem., the product formation proceeded via a formal [5,5]-sigmatropic rearrangement, a yet unknown reactivity pattern in gold catalysis. Instead of a synchronous concerted [5,5]-sigmatropic rearrangement and beyond an asynchronous concerted mode, each involving a single transition state, two energetically low transition states (1.8 and 5.6 kJ/mol) and an intermediate associate of the migrating benzyl cation and the vinyl gold species could be located in the computations.

823-78-9, 3-Bromobenzyl bromide undergoes reduction with diethylzinc in the presence of Pd(PPh3)4 to yield corresponding hydrocarbon.

Herein the first facile Cu-free click reaction between alkynyl sulfoniums RCCR1 (R = diphenyl-sulfanyliumyl, dibenzothiophenium-5-yl, thianthrenium-5-yl, etc.; R1 = H, Me, Ph, etc.) and azides R2N3 [R2 = C6H5CH2, CH2CO2H, Ph(CH2)3, etc.] at ambient temperatures in aqueous media was reported. DFT computations indicate that the sulfonium group is the key factor to gaining reactivity by stabilizing LUMO+1 and influencing the charge distribution of the triple bond. Sulfonium alkynes can be easily synthesized and scaled up, and most of them are biocompatible. Here candidate mols. were prepared and tested their use in multiple proof-of-concept biol. applications.
