Synthesis of a glucuronic acid and glucose conjugate library and evaluation of effects on endothelial cell growth

Compounds that alter endothelial cell growth are of interest in the development of angiogenesis modulators. A structurally diverse series of saccharide derivatives (glycosylamide conjugates) have been synthesized and evaluated for their effects on bovine aortic endothelial cell (BAEC) growth. Heparin-albumin (HA) reduced BAEC growth by 32% at 10mug/mL and a number of the novel saccharide conjugates from the library were found to mimic the effect of HA as they also inhibit endothelial cell survival under identical conditions. Two thiophene conjugates, thioglucamide (24% inhibition at 35muM) and a related glucuronide (26% inhibition at 33muM) were the most potent inhibitors of BAEC growth, as determined using a methylthiazol tetrazolium (MTT) assay. The effects of thioglucamide and HA on absolute cell number were also studied using cell counting experiments; thioglucamide (47% after 24h) was more potent than indicated by the MTT assay and initially reduced the BAEC number to a greater extent than HA (30% after 24h); however, its actions were over more rapidly than were HA’s as cell growth had returned to levels of the control after 72h where HA still caused 25% inhibition. The binding of the monosaccharide conjugates to fibroblast growth factor (FGF-2) in competition with heparin-albumin by ELISA was investigated to establish the possible mechanism by which glycoconjugates could alter growth but there was no general correlation between reduction in viable cell population and binding to FGF-2. No glycoconjugate reduced the proliferation of mouse mammary epithelial cells, nor did any alter gross cell morphology, supporting a proposal that the reduction in BAEC survival by monosaccharide conjugates such as thioglucamide is a result of the inhibition of cell proliferation rather than being an induction of cytotoxicity. These studies indicate that cell biological studies to determine the mechanism of action of the simple monosaccharide conjugates may be worthwhile.

The synthesis and evaluation of new benzophenone derivatives as tubulin polymerization inhibitors

Inspired by the potent inhibition activity of phenstatin and millepachine against cancer cell growth, a series of new benzophenone derivatives were synthesized and evaluated as tubulin polymerization inhibitors. Among them, compound 10a exhibited 0.029-0.062 muM of IC50 for five human cancer cell lines, which is much better than that of the two leading compounds. Flow cytometric analysis showed that 10a induces G2/M phase arrest and apoptosis in A549 cells. Cellular studies revealed that the induction of apoptosis by 10a was associated with the collapse of the mitochondrial membrane potential (MMP). Overall, the current study demonstrates that the benzophenone derivatives are promising anticancer agents by targeting tubulin.

Nickel(II) complexes of the non-steroidal anti-inflammatory drug tolfenamic acid: Synthesis, structure, antioxidant activity and interaction with albumins and calf-thymus DNA

The reaction of NiCl2¡¤6H2O with the non-steroidal anti-inflammatory drug tolfenamic acid (Htolf) in the absence or presence of a nitrogen-donor heterocyclic ligand such as 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen), 2,2?-bipyridylamine (bipyam), 2,2?-dipyridylketone oxime (Hpko) and pyridine (py) led to the formation of six novel Ni(II) mononuclear complexes. The complexes were characterized by physicochemical and spectroscopic techniques and the crystal structures of complexes [Ni(tolf-O)2(bipy)(MeOH)2], 2 and [Ni(tolf-O)2(Hpko-N,N?)2], 5 were determined by X-ray crystallography. The in vitro investigation of the ability of the complexes to scavenge 1,1-diphenyl-picrylhydrazyl, 2,2?-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) and hydroxyl radicals and to inhibit soybean lipoxygenase revealed their potential antioxidant activity. The interaction of the complexes to calf-thymus DNA was monitored by diverse techniques (UV spectroscopy, cyclic voltammetry, viscosity measurements) revealing intercalation as the most possible mode of binding. Competitive studies of the complexes with ethidium bromide were monitored by fluorescence emission spectroscopy. The interaction of the complexes with serum albumins was studied by fluorescence emission spectroscopy and the binding constants of the compounds to the albumins were calculated.

Synthesis, biological evaluation and docking studies of casuarine analogues: Effects of structural modifications at ring B on inhibitory activity towards glucoamylase

We report the total synthesis of a series of pyrrolizidine analogues of casuarine (1) and their 6-O-alpha-glucoside derivatives. The synthetic strategy is based on a totally regio- and stereoselective 1,3-dipolar cycloaddition of suitably substitutedalkenes and a carbohydrate-based nitrone. We also report the evaluation of the biological activity of casuarine and its derivatives towards a wide range of glycosidases and a molecular modeling study focused on glucoamylase (GA) in which the binding modes of the newly synthesized compounds within the enzyme cavity are investigated. The results highlight the prominent structural features of casuarine and its derivatives that make them selective glucoamylase inhibitors. A series of casuarine derivatives structurally modified at ring B of the pyrrolizidine nucleus have been synthesized and found to be selective inhibitors of fungal amyloglucosidase. The nature of the interactions between the enzyme active site and the prepared molecules has been investigated by molecular docking simulations.

Palladium-Catalyzed Amination of Aryl Sulfides and Sulfoxides with Azaarylamines of Poor Nucleophilicity

The amination of aryl sulfides and sulfoxides with azaarylamines is investigated using a palladium-N-heterocyclic carbene (NHC) complex. Because azaarylamines are less nucleophilic than anilines, more reactive diaryl sulfides and sulfoxides are found to be suitable coupling partners that liberate better leaving arenethiolate or arenesulfenate anions, instead of aryl methyl sulfides as reported previously.

An S = 3 cyanide-bridged tetranuclear FeIII2Ni II2 square that exhibits slow relaxation of magnetization: Synthesis, structure and magnetic properties

The reaction of [NiII(dpa)2(solvent)]2+ (dpa = 2,2?-dipyridyl amine) with [Bu4N][(pzTp)Fe III(CN)3] (Bu4N+ = tetrabutylammonium cation; pzTp = tetrakis(pyrazolyl)borate) in MeOH affords a tetranuclear cyano-bridged cluster, [(pzTp)2Fe2Ni 2(dpa)2(CN)6](ClO4) 2¡¤2CH3OH¡¤6H2O (1). Single-crystal X-ray analysis reveals that it is a quasi-square structure with the lateral distance being ca. 5.1 A, in which two opposing dpa-ligated Ni II ions (S = 1) are linked through cyanide bridges to two pzTp-ligated FeIII (S = 1/2) centers at the corner sites. Magnetic studies for complex 1 show ferromagnetic coupling (J/k = 10.12 K) giving rise to an S = 3 ground state; ac magnetic susceptibility measurements performed on sample 1 showed evidence of the slow relaxation effects possibly associated with single-molecule magnet behavior.
