In the anion of the title compound, (C6H11N2)[B5O6(OH)4], both six-membered borate rings adopt a flattened boat conformation with the spiro-B atom and its opposite O atom deviating from the remainders of the rings by 0.261 (3)/0.101 (2) and 0.160 (3)/0.109 (2) Å, respectively. The imidazolium cation also deviates from planarity due to rotation of the ethyl group (as indicated by the C-N-C-C tor...
In the title complex, [Cu(C(5)H(5)N(2)O(2))(C(14)H(18)N(3)O)(H(2)O)]·1.33H(2)O, the Cu(II) ion is coordinated in a slightly distorted square-pyramidal environment. The basal plane is formed by two N atoms from a 2-(5-ethyl-2-pyridyl-κN)-4-isopropyl-4-methyl-5-oxo-4,5-dihydroxy-imidazol-1-ide ligand and by one O atom and one N atom from a 5-methyl-1H-pyrazole-3-carboxyl-ate ligand. The apical po...
Abstract We report a series of ( Z )-2-acetyl-4-benzyliden-1-methyl-1 Н -imidazol-5(4 )-ones with pronounced solvent-dependent intensity fluorescence variation. The introduction the 2-acetyl group allows one to shift absorption and emission maxima long-wavelength region. have shown that these compounds can be used for staining endoplasmic reticulum fluorescent microscopy.
In the title compound, [Zn(C(23)H(14)O(6))(C(14)H(14)N(4))](n), the Zn(II) ion is four-coordinated in a distorted tetra-hedral geometry. The 1,3-bis-(imidazol-1-ylmeth-yl)benzene and 2,2'-dihy-droxy-1,1'-methyl-enebis(naphthalene-3-carboxy-l-ate) ligands con-nect the Zn(II) ions alternately in different directions, forming a layered structure parallel to the ac plane. Topological analysis revea...
Piperazine derivatives have been identified as new antidiabetic compounds. Structure-activity relationship studies in a series of 1-benzyl-4-alkyl-2-(4',5'-dihydro-1'H-imidazol-2'-yl)piperazines resulted in the identification of 1-methyl-4-(2', 4'-dichlorobenzyl)-2-(4',5'-dihydro-1'H-imidazol-2'-yl)piperazine, PMS 812 (S-21663), as a highly potent antidiabetic agent on a rat model of diabetes, ...
