In the crystal structure of the title organic salt, C(3)H(10)NO(+)·IO(4) (-)·C(12)H(24)O(6), the protonated 2-meth-oxy-ethanaminium (CH(3)OC(2)H(4)-NH(3) (+)) cation forms a 1:1 supra-molecular rotator-stator complex with the 18-crown-6 mol-ecule via N-H⋯O hydrogen bonds. The (CH(3)OC(2)H(4)-NH(3) (+)) group is attached from the convex side of the bowl-shaped crown, in contrast to similar ammon...

discussions in comparison to the control of wy14643, sandoz58-035, c9 and t11-cla, epa increased the pparα mrna levels (p = 0.024, p = 0.041, p = 0.043, and p = 0.004, respectively), even though, la had no significant effect on the pparα mrna expression (p = 0.489). materials and methods this experimental study investigated the effects of c9, t11-conjugated linoleic acid (c9, t11-cla). alpha li...

In the present work, novel 7-aryl-10, 11-dihydro-7H-chromeno [4, 3-b]quinoline-6, 8(9H, 12H)-dione derivatives were synthesized by oxidation of 7-aryl-8, 9, 10, 12-tetrahydro-7H-chromeno[4, 3-b]quinoline-6, 8-diones in the presence of silica sulfuric acid/NaNO2 with yields of 64-74%. Cytotoxic activity of synthesized compounds was assessed on three different human cancer cell lines (K562, LS180...

In recent years, several oconjugation protocols have been developed to improve the functional properties of the enzyme lysozyme. In this study, the optimum conditions of lysozyme – oxidized inulin conjugation and functional properties of the modified lysozyme were investigated. Initially, inulin (MW about 25 kDa) was oxidized by periodate to provide the reactive carbonyl groups  to attach to am...

The levels of oxidized serum lipoproteins are increased in humans and animals with diabetes. We have examined the contribution of dietary oxidized lipids on the levels of oxidized lipoproteins. In both control and streptozocin induced diabetic rats, the oxidized lipid content of mesenteric lymph chylomicrons (CM) increased when increasing quantities of oxidized lipids were administered intragas...
