Synthesis, characterization, reactivity and structure of some mono and binuclear (eta6-p-cymene)ruthenium(II) complexes

Reactions of [{Ru(eta6-C10H14)Cl2}2] (eta6-C10H14=p-cymene H3C-C6H4-CH(CH3)2) with 4-cyanopyridine (referred hereafler as CNPy) in 1:1 and 1:2 molar ratios in dichloromethane yields the binuclear complex [{Ru(eta6-C10H14)Cl2} 2(mu-CNPy)] and the mononuclear complex [Ru(eta6-C10H14)Cl2(CNPy)]. The latter complex further reacts with [{Ru(eta6-C6Me6)Cl2}2] and [Ru(eta5-C5H5)(PPh3) 2Cl] to give 4-cyanopyridine bridged complexes [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(mu6-C6Me 6)Cl2] and [Cl2(eta6-C10H 14)Ru(mu-CNPy)Ru(eta5-C5H 5)(PPh3)2]+. The complex [Ru(eta6-C10H14)Cl2(CNPy)] also undergoes metathetical reactions with EPh3 (E=P, As or Sb) to give complexes with the general formulations [Ru(eta6-C10H14)Cl2(EPh 3)], however its reaction with diphenylphosphinomethane (dppm) in a 1:1 ratio gives the mononuclear complex [Ru(eta6-C10H14)Cl2(dppm)] in which the dppm ligand is present in uncommon coordination mode (eta1-dppm). The reaction products have been characterized by microanalyses and spectroscopic studies (IR, 1H-, 13C-, 31P-NMR). The structure of [Ru(eta6-C10H14)Cl2(CNPy)] [a=10.984(1), b=14.052(1), c=12.189(1) A; beta=114.810(1); V=1707.8(4) A3; Dcalc=1.596 g cm-3; monoclinic P21/c; Z=4] and confirmation of uncommon coordination mode of dppm, in [Ru(eta6-C10H14)Cl2(dppm)] [a=11.504(3), b=19.532(3), c=15.942(3) A; beta=96.08(2); V=3562(2) A3; Dcalc=1.446 g cm-3; monoclinic P21/n; Z=4] has been determined by X-ray crystallography.

Synthesis of benzaldehyde-functionalized LewisX trisaccharide analogs for glyco-SAM formation

LewisX (Lex) antigen based carbohydrate-carbohydrate interactions are mediated by complexation of metal ions. Although theoretical studies about the influence of participating hydroxyl groups in the Le x trisaccharide head group (Galbeta(1-4)[Fucalpha(1-3)]GlcNAc) could gave same rudimental information about the basic mechanism behind this interaction, a little is known about orientation and configuration of the hydroxyl groups required for the specific interaction mediated by Ca 2+ complexation. Therefore, there is a need of non-natural derivatives to provide detailed information about the requirements for hydroxyl group arrangement in Lex head group surface plasmon resonance and gold nanoparticle techniques have shown to be powerful tools to investigate carbohydrate-carbohydrate interactions. Benzaldehyde-functionalized glycans can be used for attachment to both gold nanoparticles and surface plasmon resonance sensor surfaces. Therefore, seven benzaldehyde equipped Lex analogs including the natural trisaccharide were synthesized utilizing convergent approach. The derivatives were applied in ongoing carbohydrate-carbohydrate interaction studies by surface plasmon resonance experiments to prove theoretical postulate about the structural requirements of hydroxyl group arrangements in Lex trisaccharides.

Influence of methionine?ruthenium complex on the fibril formation of human islet amyloid polypeptide

Abstract: The abnormal aggregation and deposition of human islet amyloid polypeptide (hIAPP) are implicated in the pathogeny of type 2 diabetes mellitus (T2DM). Many aromatic ring-containing Ru complexes inhibit the aggregation of hIAPP. A new Ru complex Ru(bipy)(met)2¡¤3H2O (1), where bipy is 2,2?-bipyridine and met is methionine, was synthesized and employed to resist the fibril formation of hIAPP and to promote the biocompatibility of metal complexes. Two polypyridyl Ru complexes, namely [Ru(bipy)3]Cl2(2) and Ru(bipy)2Cl2(3), were used for comparison. Results reveal that the three Ru complexes can inhibit hIAPP aggregation and depolymerize mature hIAPP fibrils. Interaction studies show that Ru complexes bind to hIAPP through metal coordination, hydrophobic interaction, and other intermolecular forces. The binding of the three compounds is spontaneous and exothermic. The compounds also rescue peptide-induced cytotoxicity to some extent. Similar to 3, the novel methionine?Ru complex 1 exhibits an enhanced inhibitory effect and binding affinity to hIAPP possibly because of the smaller steric hindrance and more profitable molecular configuration of 1 than those of 2. The newly designed amino acid?Ru complex may provide new insights into the treatment of T2DM and related amyloidosis diseases. Graphical abstract: Methionine?Ru complex effectively impedes the fibril formation of human islet amyloid polypeptide. [Figure not available: see fulltext.].

Combining cross-metathesis and activity-based protein profiling: New beta-lactone motifs for targeting serine hydrolases

beta-Lactones are a privileged structural motif as enzyme inhibitors and chemical probes, particularly for the inhibition of enzymes from the serine hydrolase class. Herein, we demonstrate that cross-metathesis (CM) of alpha-methylene-beta-lactones offers rapid access to structurally diverse, previously unexplored beta-lactones. Combining this approach with competitive activity-based protein profiling (ABPP) identified lead beta-lactone inhibitors/probes for several serine hydrolases, including disease-associated enzymes and enzymes of uncharacterized function. The structural diversity afforded by the alpha-methylene-beta-lactone scaffold thus expands the landscape of serine hydrolases that can be targeted by small-molecule inhibitors and should further the functional characterization of enzymes from this class through the optimization of target-selective probes.
