Lectin-carbohydrate interactions are important for many biological processes of high pharmaceutical interest. Multi-valent carbohydrate conjugates (glycoclusters) have been frequently used to study and manipulate these interactions. In this report, we present the synthesis of trimeric glucose and mannose conjugates that have been assembled with an AB3 scaffold based on adamantane. Several neoglycoconjugates bearing three carbohydrates have been synthesized with different ethylene glycol spacers between the sugar moieties and the adamantyl core. An additional orthogonal functionality at the remaining adamantane bridgehead position allows the conjugation of these trimeric cluster glycosides to other functional molecules such as fluorescent dyes or a solid support for the construction of glycoarrays. We have evaluated the binding properties of trivalent carbohydrate derivatives to ConA as a model lectin in solution by STD-NMR and on a lectin array by using fluorescent glycoconjugates.

New glucopyranosyl Schiff base zinc complexes, [Zn(GlcSal)2] (1; GlcSalH=N-(2-deoxy-beta-D-glucopyranos-2-yl-salicylaldimine) and [Zn(AcOGlcSal)2] (2; AcOGlcSalH=N-(2-deoxy-beta-D-1,3,4,6- tetraacetylglucopyranos-2-yl-salicylaldimine) were synthesized, and characterized by spectral and analytical methods. The interaction between the Zn complexes and mononucleotides was investigated by 1H-NMR, 31P-NMR and UV/VIS spectroscopies. Mononucleotides, cytidine 5′-monophosphate (CMP) and uridyl 5′-monophosphate (UMP), interacted with these complexes to form a 1: 1 complex with 1 and a 1: 2 complex with 2, depending on the presence of the OH group of glucopyranosyl substituents. The DNA-cleavage activities of 1 and 2 were studied using plasmid DNA (pBR322) in a medium of 5 mM Tris¡¤HCl/50 mM NaCl buffer in the presence of H2O 2. The DNA-cleavage activity decreased in the order of 2>1>Zn(OAc)2, indicating the significant promoting effect of the glucopyranosyl Schiff base ligand and the participation of the glucopyranosyl OH groups in the cleavage mechanism. The mechanism of the DNA cleavage by 1 and 2 was investigated by evaluation of the effect of a HO radical scavenger and a singlet-oxygen (1O 2) quencher under aerobic conditions. The former exhibited little effect, excluding the HO. radical as an active species and supporting the hydrolysis mechanism for the main process of the DNA cleavage. The latter quencher somewhat hindered the cleavage, indicating the partial participation of a 1O2 as a competitive active species in the present system. Copyright

New examples of adducts between di- (and, in one instance, tetra-) functional nitrogen ligands and planar ‘platform-like’ dinuclear copper(ii) complexes, [Cu2L2], incorporating the 1,3-aryl linked bis-beta-diketonato bridging ligand 1,1?-(1,3-phenylene)-bis(4,4- dimethylpentane-1,3-dione) (H2L) have been synthesised. The X-ray structures of six adduct species are reported. The interaction of [Cu 2(L)2] with the ditopic ligand aminopyrazine (apyz) yielded the sandwich-like tetranuclear species [(Cu2L 2(apyz))2]. A variable-temperature magnetochemical investigation of this product indicated weak antiferromagnetic coupling between the (five-coordinate) copper centres, mediated by the 2-aminopyrazine linkers. An analogous structure, [(Cu2L2(dabco))2] (dabco = 1,4-diazabicyclo[2.2.2]octane), was generated when dabco was substituted for aminopyrazine while use of 4,4?-dipyridyl sulfide (dps) and 4,4?-(1,3-xylylene)-bis(3,5-dimethylpyrazole) (xbp) as the ditopic ‘spacer’ ligands resulted in polymeric species of type [Cu2L 2(dps)]n and [Cu2L2(xbp)] n, respectively. These latter species exist as one-dimensional chain structures in which copper(ii) centres on different dinuclear platforms are linked in a ‘zigzag’ fashion. In contrast, with 2,2?-dipyridylamine (dpa) a discrete complex of type [Cu2L2(dpa)2] formed in which one potential pyridyl donor from each 2,2?-dipyridylamine ligand remains uncoordinated. The use of the potentially quadruply-bridging hexamethylenetetramine (hmt) ligand as the linker unit was found to give rise to an unusual two-dimensional polymeric motif of type [(Cu2(L 2)2)3(hmt)2]n. The product takes the form of a (6,3) network, incorporating triply bridging hexamethylenetetramine units. The Royal Society of Chemistry 2006.

[Mn(SCN)2(L)4/2] where L = py, gamma-pic, pyCH 2OH, py-NH-py (dpa) complexes have been prepared and studied by IR and UV-Vis spectroscopy, and X-ray crystallography. Electronic structures of the complexes were calculated using DFT method, and the descriptions of frontier molecular orbitals and the relocation of the electron density of the compounds were determined. The differences in acceptor properties of the used pyridine derivatives ligands were shown in the values of ligand field parameters determined from electronic spectra of the complexes. The magnetic properties revealed paramagnetic behavior with a weak ferromagnetic interaction and the van Vleck contribution for [Mn(SCN)2(py)4] (1), ideal paramagnetism for [Mn(SCN)2(gamma-pic)4] (2) and a weak antiferromagnetic interaction and diamagnetic contribution for [Mn(SCN) 2(pyCH2OH)2] (3).

The reaction between trans-[RuCl2(dmso-S)4] (dmso = dimethyl sulfoxide) and di-2-pyridylamine (Hdpa) in EtOH-H2O at ca. 273 K afforded trans(Cl),cis(S)-[RuCl2(Hdpa)(dmso-S)2] (1) in moderate to high yield. When dissolved in DMSO, 1 rearranged to the more thermodynarnically stable cis(Cl),cis(S)-[RuCl2(Hdpa)(dmso-S) 2] (2), along with cis(Cl),trans(X)-[RuCl2(Hdpa)(dmso) 2] (X = S- or O-bonded dmso). The reaction of 2 with Ag(OTf) afforded cis(Cl,S),trans.(O,S)-[RuCl(Hdpa)(dmso-O)(dmso-S)2](OTf) (3-(OTf)) (OTf- = trifluoromethanesulfonate). X-ray crystal structures of 1, 2, and 3-(OTf) revealed that the conformation of the six-membered chelate ring formed by the Hdpa ligand with the Ru ion varies according to interactions among the co-ligands (dmso and Cl-) and the coun-ter-anion (OTf -). For 3 ¡¤ (OTf). the structural parameters, apart from the dmso-O ligand, were essentially comparable to those of 2, except for the axial Cl- ligand; the remaining axial site is occupied by the O-donor of the dmso ligand instead of the S-donor. The solution structures (in DMSO solution) of 1, 2, and 3-(OTf) are discussed on the basis of their 1HNMR spectra. In 3-(OTf), “flapping” of the Hdpa ligand causes the coordination modes (O- and S-bonded) of the two axial dmso ligands to undergo mutual alternation.
