Furanodictine A and B: Amino sugar analogues produced by cellular slime mold Dictyostelium discoideum showing neuronal differentiation activity

We investigated the constituents of Dictyostelium discoideum to clarify the diversity of secondary metabolites of Dictyostelium cellular slime molds and to explore biologically active substances that could be useful in the development of novel drugs. From a methanol extract of the multicellular fruit body of D. discoideum, we isolated two novel amino sugar analogues, furanodictine A (1) and B (2). They are the first 3,6-anhydrosugars to be isolated from natural sources. Their relative structures were elucidated by spectral means, and the absolute configurations were confirmed by asymmetric syntheses of 1 and 2. These furanodictines potently induce neuronal differentiation of rat pheochromocytoma (PC-12) cells.

Some mutual interactions between lactones and other aroma constituents of food present in concentrations below their odor threshold

To investigate the contribution of subthreshold aroma constituents to the flavor of food, mutual interaction between saturated gamma- And delta lactones (C6- C1 2) and some minor odorants found in various food materials was investigated by sensory evaluation. By the triangle test, the detection odor threshold value of the mixture of (E)-2-hexenyl hexanoate and each of 4-octanolide, 5-hexanolide, 5-nonanolide and 5- decanolide at the ratio of 90:10 decreased significantly from 1 ppm to 0.1 ppm. The (Z)-3-hexenol and the mixture of (Z)-3- hexenol and saturated gamma and delta lactones (C6- C1 2) were evaluated by the same method. The odor intensity of the mixture of (Z)-3-hexenol and each of the following eight lactones such as 4- And 5-hexanolide, 4-octanolide, 4- And 5- nonanolides, 5-decanolide, and 4- And 5-undecanolides present in each concentration below their odor threshold was enhanced significantly. In addition, the odor intensity was enhanced significantly in the mixture of d-limonene + 4-hexanolide, vanillin + 5-hexanolide, and citronellol + both 4-, and 5- hexanolides. The effect of addition of 4-hexanolide on selfadaptation in concentration below its odor threshold to the model solution of some supra-threshold odorants was also studied. The presence of 4-hexanolide in the (E)-2-hexenyl hexanoate and (Z)-3-hexenoI suppressed self-adaptation and the prolongation of the odor sensation by mutural interaction between two odorants was indicated.

Structure and biological activities of metal complexes of flumequine

The reaction of CoCl2¡¤6H2O with the quinolone antimicrobial agent flumequine (Hflmq) in the absence or presence of the alpha-diimines 2,2?-bipyridine (bipy), 1,10-phenanthroline (phen) or 2,2?-bipyridylamine (bipyam) resulted in the formation of four mononuclear complexes which were characterized with physicochemical and spectroscopic techniques. The crystal structures of [Co(flmq)2(bipy)]¡¤2H2O, [Co(flmq)2(phen)]¡¤1.6MeOH¡¤0.4H2O and [Co(flmq)2(bipyam)]¡¤H2O were determined by X-ray crystallography. The interaction of the complexes with calf-thymus DNA (CT DNA) was investigated by UV spectroscopy, viscosity measurements, cyclic voltammetry and competitive studies with ethidium bromide in order to evaluate the possible DNA-binding mode and to calculate the corresponding DNA-binding constants. The binding of the complexes to human or bovine serum albumin was studied by fluorescence emission spectroscopy and the corresponding binding constants were determined. The antimicrobial activity of the Co(II)-flumequine and the recently reported Cu(II)-flumequine complexes was tested against four different microorganisms (Escherichia coli, Xanthomonas campestris, Staphylococcus aureus and Bacillus subtilis) and was found to be similar to that of free Hflmq. The antiproliferative activity of previously reported complexes [Cu(flmq)(phen)Cl], [Zn(flmq)(phen)Cl] and [Ni(flmq)2(phen)] against human ovarian (A2780) and lung (A549) cancer cell lines is also reported in comparison to the cobalt analogue, [Co(flmq)(phen)Cl], 3, highlighting important differences among the various complexes which may be due to different uptake and modes of action.

3-(Dimethylamino)-1-propylamine: A cheap and versatile reagent for removal of byproducts in carbohydrate chemistry

Inexpensive 3-(dimethylamino)-1-propylamine (DMAPA) was found to be effective in anomeric deacylation reactions giving 1-O deprotected sugars in high yield as precursors for the formation of imidate glycosyl donors. DMAPA was also found to be useful for removing excess reagents such as benzoyl chloride, tosyl chloride, and 2,2,2-trifluoro-N-phenylacetimidoyl chloride. The deacylation reaction could be conducted in moist THF and did not require chromatographic purification since an acidic wash was sufficient to remove excess reagent and the formed byproduct.

Molecular engineering to improve the charge carrier balance in single-layer silole-based OLEDs

We report a molecular engineering study on optical, structural and electrical properties of seven silole derivates aimed at enhancing the charge carrier balance in single-layer devices. By functionalizing two hole-transporting groups, dipyridylamine and anthracene, on the silole ring, we have investigated the influence of both substituents on the hole current. We have concluded that in contrast to dipyridylamine groups, anthracene groups decrease the charge carrier balance since the latter groups not only increase the hole current but also electron contribution. Mixing these hole-transporting groups and doubling their number lead to a novel silole becoming a very efficient emissive layer exhibiting threshold voltage below 3 V and luminous efficiency Le = 0.8 cd A-1 at 7 V.
