116082-89-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 116082-89-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,0,8 and 2 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116082-89:
(8*1)+(7*1)+(6*6)+(5*0)+(4*8)+(3*2)+(2*8)+(1*9)=114
114 % 10 = 4
So 116082-89-4 is a valid CAS Registry Number.

New gold (I) complexes with 5-aromatic ring-1, 3, 4-oxadiazole-2-thione and triphenylphosphine as potential multifunctional materials

Zhao, Yu Qiang,Zhou, Jie,He, Renze,Wang, Guang Ke,Miao, Lan Xi,Xie, Xiao Guang,Zhou, Ying

, (2020)

Three new gold (I) complexes (4a, 4b, 4c) with 5-aromatic ring-1, 3, 4-oxadiazole-2-thione and triphenylphosphine as ligands were synthesized. Structures of 4a and 4b were determined through X-ray single-crystal diffraction, and it displayed that 4a and 4b had the same metal coordination pattern, wherein the ligand was coordinated by the sulfur atom to the central metal ion of gold (I). The optical properties of these gold (I) complexes were studied both in solution and in solid-state. In DMSO, 4a and 4b peaked at 415 nm and 443 nm, respectively, and the CIE coordinates of 4a and 4b in the solid-state were in the green area namely, (0.26, 0.46) and (0.24, 0.41). HOMO/LUMO levels and bandgaps of 4a, 4b and 4c were assessed by UV spectrum estimation, electrochemical method, and theoretical calculations. The observation hinted that the photophysical properties and energy levels of these gold (I) complexes can be adjusted by the introduction of different substituent aromatic rings at the 5-position of the 1, 3, 4-oxadiazole-2-thiol moiety. The findings of good optical, electrochemical and thermal properties of these new gold (I) complexes demonstrated their potential in the future studies as multifunctional materials.

Metallo-β-lactamases (MBLs) cause resistance of Gram-negative bacteria to β-lactam antibiotics and are of serious concern, because they can inactivate the last-resort carbapenems and because MBL inhibitors of clinical value are still lacking. We previously identified the original binding mode of 4-amino-2,4-dihydro-5-(2-methylphenyl)-3H-1,2,4-triazole-3-thione (compound IIIA) within the dizinc active site of the L1 MBL. Herein we present the crystallographic structure of a complex of L1 with the corresponding non-amino compound IIIB (1,2-dihydro-5-(2-methylphenyl)-3H-1,2,4-triazole-3-thione). Unexpectedly, the binding mode of IIIB was similar but reverse to that of IIIA. The 3 D structures suggested that the triazole–thione scaffold was suitable to bind to the catalytic site of dizinc metalloenzymes. On the basis of these results, we synthesized 54 analogues of IIIA or IIIB. Nineteen showed IC50 values in the micromolar range toward at least one of five representative MBLs (i.e., L1, VIM-4, VIM-2, NDM-1, and IMP-1). Five of these exhibited a significant inhibition of at least four enzymes, including NDM-1, VIM-2, and IMP-1. Active compounds mainly featured either halogen or bulky bicyclic aryl substituents. Finally, some compounds were also tested on several microbial dinuclear zinc-dependent hydrolases belonging to the MBL-fold superfamily (i.e., endonucleases and glyoxalase II) to explore their activity toward structurally similar but functionally distinct enzymes. Whereas the bacterial tRNases were not inhibited, the best IC50 values toward plasmodial glyoxalase II were in the 10 μm range.

Novel 1,3,4-oxadiazole thioether derivatives targeting thymidylate synthase as dual anticancer/antimicrobial agents

Du, Qian-Ru,Li, Dong-Dong,Pi, Ya-Zhou,Li, Jing-Ran,Sun, Jian,Fang, Fei,Zhong, Wei-Qing,Gong, Hai-Bin,Zhu, Hai-Liang

, p. 2286 - 2297 (2013/05/09)

A series of novel 1,3,4-oxadiazole thioether derivatives (compounds 9-44) were designed and synthesized as potential inhibitors of thymidylate synthase (TS) and as anticancer agents. The in vitro anticancer activities of these compounds were evaluated against three cancer cell lines by the MTT method. Among all the designed compounds, compound 18 bearing a nitro substituent exhibited more potent in vitro anticancer activities with IC50 values of 0.7 ± 0.2, 30.0 ± 1.2, 18.3 ± 1.4 μM, respectively, which was superior to the positive control. In the further study, it was identified as the most potent inhibitor against two kinds of TS protein (for human TS and Escherichia coli TS, IC50 values: 0.62 and 0.47 μM, respectively) in the TS inhibition assay in vitro and the most potent antibacterial agents with MIC (minimum inhibitory concentrations) of 1.56-3.13 μg/mL against the tested four bacterial strains. Molecular docking and 3D-QSAR study supported that compound 18 can be selected as dual antitumor/antibacterial candidate in the future study.
