Wu, Yun;Wei, Wenzhe;Luo, Jiayi;Pan, Yang;Yang, Mengting;Hua, Ming;Chu, Wenhai;Shuang, Chendong;Li, Aimin research published 《 Comparative Toxicity Analyses from Different Endpoints: Are New Cyclic Disinfection Byproducts (DBPs) More Toxic than Common Aliphatic DBPs?》, the research content is summarized as follows. In recent years, dozens of halogenated disinfection byproducts (DBPs) with cyclic structures were identified and detected in drinking water globally. Previous in vivo toxicity studies have shown that a few new cyclic DBPs possessed higher developmental toxicity and growth inhibition rate than common aliphatic DBPs; however, in vitro toxicity studies have proved that the latter exhibited higher cytotoxicity and genotoxicity than the former. Thus, to provide a more comprehensive toxicity comparison of DBPs from different endpoints, 11 groups of cyclic DBPs and nine groups of aliphatic DBPs were evaluated for their comparative in vitro and in vivo toxicity using human hepatoma cells (Hep G2) and zebrafish embryos. Notably, results showed that the in vitro Hep G2 cytotoxicity index of the aliphatic DBPs was nearly eight times higher than that of the cyclic DBPs, whereas the in vivo zebrafish embryo developmental/acute toxicity indexes of the cyclic DBPs were roughly 48-50 times higher than those of the aliphatic DBPs, indicating that the toxicity rank order differed when different endpoints were applied. For a broader comparison, a Pearson correlation anal. of DBP toxicity data from nine different endpoints was conducted. It was found that the observed Hep G2 cytotoxicity and zebrafish embryo developmental/acute toxicity in this study were highly correlated with the previously reported in vitro CHO cytotoxicity and in vivo toxicity in aquatic organisms (P < 0.01), resp. However, the observed in vitro toxicity had no correlation with the in vivo toxicity (P > 0.05), suggesting that the toxicity rank orders obtained from in vitro and in vivo bioassays had large discrepancies. According to the observed toxicity data in this study and the candidate descriptors, two quant. structure-activity relationship (QSAR) models were established, which help to further interpret the toxicity mechanisms of DBPs from different endpoints.

A series of Fe(II) complexes [(L)₂Fe] and Fe(III) complexes [(L)₂Fe]Cl from Fe(II)/(III) chlorides and N-(8-quinolyl)-X-salicylaldimine Schiff base ligands (HL, Hqsal-X₂/X: X = 3,5-Br₂, 3,5-Cl₂, 5-Br, 5-Cl) were successfully synthesized and characterized by spectroscopic (FT-IR, ¹H-NMR), mass spectrometry, thermogravimetric anal. (TGA), and single crystal X-ray crystallog. techniques. The interaction of complexes 1-8 with calf thymus DNA (CT-DNA) was determined by UV-Vis and fluorescence spectroscopy. The complexes exhibited good DNA-binding activity via intercalation. The mol. docking between a selected complex and DNA was also investigated. The in vitro anticancer activity of the Schiff base ligands and their complexes were screened against the A549 human lung adenocarcinoma cell line. The complexes showed anticancer activity toward A549 cancer cells while the free ligands and iron chloride salts showed no inhibitory effects at 100μM. In this series, complex [Fe(qsal-Cl₂)₂]Cl (6) showed the highest anticancer activity against A549 cells (IC₅₀ = 10μM). This is better than two well-known anticancer agents (Etoposide and Cisplatin). Furthermore, the possible mechanism for complexes 1–8 penetrating A549 cells through intracellular ROS generation was investigated. The complexes containing dihalogen substituents 1, 2, 5, and 6 can increase ROS in A549 cells, leading to DNA or macromol. damage and cell-death induction.

A highly efficient and simple route for the synthesis of benzo[ b]furans was developed by palladium-catalyzed cross-coupling reaction of 2-halobenzo[ b]furans with aryl, alkynyl, and alkylaluminum reagents. Various 2-aryl-, 2-alkynyl-, and 2-alkyl benzo[ b]furans was obtained in 23-97% isolated yields using 2-3 mol% PdCl 2/4-6 mol% XantPhos as the catalyst under mild reaction conditions. The aryls beared electron-donating or electron-withdrawing groups in 2-halobenzo[ b]furans gave products in 40-97% isolated yields. In addition, aluminum reagents containing thienyl, furanyl, trimethylsilanyl, and benzyl groups worked efficiently with 2-halobenzo[ b]furans as well, and three bioactive mols. with benzo[ b]furans skeleton were synthesized. Furthermore, the broad substrates scope and the typical maintenance of vigorous efficiency on gram scale made this protocol a potentially practical method to synthesize benzo[ b]furans. On the basis of the exptl. results, a possible catalytic cycle was proposed.

Complex assembly preferences and resultant spin state choice and Jahn-Teller distortion mode in twelve Mn(III) complexes of varying nuclearity with Schiff base chelate ligands of different sizes are compared. Mononuclear complexes [Mn(5-F-Sal₂323)]OTf (1), [Mn(5-F-Sal₂323)]ClO₄ (2) and [Mn(5-F-Sal₂323)]NO₃, (3) with the 8-carbon R-Sal₂323 chelate type show rare axial compression at room temperature and complexes (2) and (3) also show reversible thermal spin state switching from spin quintet to triplet states on cooling. The prevalence of atypical axial compression is further probed by single crystal diffraction studies on high spin mononuclear complexes (4)-(7) with the longer 9-carbon R-Sal₂333 chelate series using [Mn(3-OEt-Sal₂333)]BF₄, (4) [Mn(3,5-diOMe-Sal₂333)]BF₄·0.5PrOH, (5), [Mn(5-F-Sal₂333)]BPh₄, (6) and [Mn(5-NO₂-Sal₂333)]BPh₄, (7) as examples. Ring closure of both the 8-carbon R-Sal₂323 and longer 9-carbon R-Sal₂333 ligands was also observed yielding a ligand with a 6-membered ring in the mononuclear complex [Mn(3-OMe,5-NO₂-Sal₂333^6R)]·0.07MeOH·0.93MeCN (8) in contrast to a protonated 5-membered ring in the dimeric complex [Mn₂(5-Cl-Sal₂323^H5R)₂](ClO₄)₂·1.85EtOH·0.33MeCN, (9) with the R-Sal₂323 chelate type. Finally comparison of the assembly modes of Mn(III) complexes of the 8-carbon R-Sal₂323 and 9-carbon R-Sal₂333 series with those of the shorter 7-carbon R-Sal₂322 ligand series reveal that the mononuclear assembly mode is not favored with the smaller chelate. Instead three dimeric or cluster complexes with rearranged ligands were recovered in low yield. The structures of these complexes [Mn₂(5-NO₂-Sal₂322^5R)₂]·2BuOH, (10), [Mn₂(3,5-diBr-Sal₂322^5R)(3,5-diBr-Sal)₃]·0.7EtOH·2.61MeCN, (11) and [Mn₂Na(3-NO₂,5-OMe-Sal₂322^5R)]ClO₄·0.5MeCN (12) are reported and compared with examples with the longer chain R-Sal₂323 and R-Sal₂333 chelate ligands.

3,5-Dibromosalicylaldehyde is a copper complex that has been synthesized from 3,5-dibromosalicylaldehyde and copper chloride. FTIR spectroscopy revealed that the coordination geometry of the copper complex is octahedral with two nitrogen atoms in the equatorial plane. The presence of hydrogen bonding interactions was confirmed by homologous protein adsorption experiments. This chemical structure was determined using X-ray crystallography and fluorescence probe experiments. The copper complex showed high affinity for malonic acid, which is an ester hydrochloride. The molecular mechanism of this interaction is based on adsorption, which occurs through hydrogen bonding interactions and hydrophobic interactions. Structural analysis revealed that the polymeric matrix consists of a three-dimensional network of crosslinked chains, while FTIR analysis indicated a possible disulfide bond between two cysteine residues., 90-59-5.
