Since flavanone oximes derivatives (ethers) have been shown to modulate the growth of Yoshida Sarcoma cells in vivo and to induce apoptosis, the effects of these substances on immortalized cell lines growth were examined. Cell viability and sensitivity to investigated

A novel complex, Rutoxyl [rutin/4-acetamide-1-hydroxy-2,2,6,6-tetramethylpiperidinium] was synthesized and its structure and anticancer activity were investigated. The results reported here are consistent with our idea, that the formation of such a complex of two biologically active molecules: polyphenolic flavonoid antioxidant (Rutin)

Two novel 2,2,6,6-tetramethylpiperidine derivatives (Tempace and Troxyl) were synthesized and their capacity to act as scavengers of superoxide, inhibitors of iron and ascorbate-driven Fenton reaction and radioprotectors was tested. The possibility for one-electron oxidation of novel compounds by heme-ferryl species

The piperidine nitroxides Tempamine and Tempace have been studied for their effect on doxorubicin (DOX) and hydrogen peroxide (H(2)O(2)) cytotoxicity in immortalized B14 cells, a model for neoplastic phenotype. The significance for nitroxide performance of the substituent in position 4

The novel nitroxyl, Tempicol-3 (nitroxide-N-oxide) was synthesized and its capacity to act as a scavenger of hydroxyl radicals was tested. The concentration-dependent reducibility of this novel compound was also examined and compared with those of previously characterized nitroxides, Tempo and

Regioselective oxidation was applied to commercial curdlan for the preparation of its water-soluble derivatives with improved antioxidant activities, using a 4-acetamido-2,2, 6,6-tetramethylpiperidine-1-oxyl radical/NaClO/NaClO2 system at pH 4.8 and 40°C. The structural features, molecular properties, and chain conformations of the oxidised

Haemolytic anaemia is variable among patients with sickle cell anaemia and can be estimated by reticulocyte count, lactate dehydrogenase, aspartate aminotransferase and bilirubin levels. Using principal component analysis of these measurements we computed a haemolytic score that we used as
