The [N’-(2-chloroethyl)-N’-nitrosoamino]carbonyl [(2- chloroethyl)nitrosocarbamoyl, CNC] moiety containing compounds CNC- glycinamide 2d, CNC-amino acid derivatives 7a-d, and carbohydrate-CNC-amino acid conjugates 13, 18, 22, 23, 27, and 28 were synthesized and evaluated in vivo for their anticancer activities against the murine lymphocytic leukemia P388 using the National Cancer Institute (NCI) protocol. The most active compound was 2d with a 520% increase in life span (%ILS) and 6/6 survivors after 60 days. The CNC-amino acid analogs 7a-d possessed high to moderate activities with maximum %ILS values of 270, 174, 141 and 132, respectively. Among the carbohydrate-CNC-amino acid derivatives the alpha-methyl glycoside derivatives 22 and 23 were most active with maximum %ILS values of 277 and 137, respectively, followed by the hemiacetal carbohydrate analogs 13 and 18 with %ILS values of 93 and 149, respectively, and the tetra-O-acetyl derivatives 27 and 28 with %ILS of 110 and 111, respectively. Compounds 7b, 18, 23 and 28 were then tested in vivo against the murine lymphoid leukemia L1210 using the NCI protocol. In this case, the hemiacetal type carbohydrate- CNC-amino analog 18 had the highest activity with a maximum %ILS value of 477 and 4/6 survivors on day 60, followed by 7b (275% ILS), 23 (152% ILS) and 28 (106% ILS). The lipophilicities of all CNC compounds were determined by the partition coefficient using the UV method. A correlation of %ILS values with log P values indicated, in general, an increase in cytotoxicity with a decrease in hydrophilicity for the carbohydrate-CNC-amino acid conjugates 13, 18, 22, 23 and the clinical drugs streptozotocin (1e), chlorozotocin (1f), and cymerin (1g).

The Schiff bases derived from salicylaldehydes and o-amino thiophenol (1, 1?) react with uranyl salts to yield two series of uranyl-thioschiff base complexes of the type (3-6) and (3?-6?). These Schiff bases act as tridentate ONS donor ligands. Similar reaction of o aminothiophenol with diketones yield benzthiazolines (2, 2?) and rearranged to thioschiff bases of N2S2 donor systems in uranyl complexes (7, 7?). The peroxo derivatives of the formulae (8, 8?) and (9, 9?) have also been isolated. The complexes have been characterised by elemental analyses, IR and thermal studies. The peroxo contents have been determined by redox titration and are found to be thermally stable.

Low calorie sweeteners (LCS) are prevalent in the food supply for their primary functional property of providing sweetness with little or no energy. Though tested for safety individually, there has been extremely limited work on the efficacy of each LCS. It is commonly assumed all LCS act similarly in their behavioral and physiological effects. However, each LCS has its own chemical structure that influences its metabolism, making each LCS unique in its potential effects on body weight, energy intake, and appetite. LCS may have different behavioral and physiological effects mediated at the sweet taste receptor, in brain activation, with gut hormones, at the microbiota and on appetitive responses. Further elucidation of the unique effects of the different commercially available LCS may hold important implications for recommendations about their use for different health outcomes.

Five Cd(II) complexes with the anion of 5-NO2-salicylaldehydeH (5-NO2-saloH) in the absence or presence of the alpha-diimine 1,10-phenanthroline (phen), 2,2?-dipyridylamine (dpamH), 2,2?-dipyridine (bipy), or 2,9-dimethyl-1,10-phenanthroline (neoc) were synthesized and characterized as [Cd(5-NO2-salo)2(CH3OH)2] (1), [Cd(5-NO2-salo)2(phen)]·2CH3OH·H2O (2), [Cd(5-NO2-salo)2(dpamH)] (3), [Cd3(5-NO2-salo)6(bipy)2] (4), and [Cd(5-NO2-salo)(neoc)(NO3)]2 (5). Based on spectroscopic results (IR, UV, NMR), elemental analysis and conductivity measurements an octahedral geometry around cadmium metal ion is suggested, with the 5-NO2-salicylaldehyde ligand having different coordination modes. The structures determined by X-ray crystallography verified neutral mononuclear 1-3 and trinuclear 4. Simultaneous TG/DTG-DTA technique was used to analyze the thermal behavior of 1, 2, and 3. The complexes bind tightly to calf-thymus DNA mainly by intercalation, as concluded by DNA viscosity measurements and exhibit significant displacement of EB from the EB-DNA complex.

The preparation and characterization of some copper(II)nitrito complexes with 2,2′-dipyridylamine (dipyam) are reported. The X-ray diffraction crystal structures of the [Cu(CH3COO)(dipyam)(ONO-O,O’)] (I) and [Cu(dipyam)(ONO-O,O’)(mu-ONO-O)]2·2CH3CN (II) complexes have been investigated. I consists of two crystallographically independent [Cu(acetato)(dipyam)-(ONO)] neutral complexes, self-assembled by cooperative N-H···O and C-H···O intermolecular interactions in supramolecular tetrameric units. Each copper atom exhibits a tetrahedrally-distorted square-basal geometry of the N2O2 donor set, with the second oxygen atoms of the cis-monodentate nitrito and of the acetato group weakly bound in nearly axial positions. II is a rare example of a dinuclear nitrito copper(II) derivative containing both cis-monodentate and O-bridging nitrito ligands. Each metal ion shows a distorted square-pyramidal coordination with the basal oxygen from the nitrito bridge occupying the axial site of the centrosymmetric complex. The H-bonding between the dipyam amino groups and acetonitrile molecules prevents the self-assembling of the dinuclear complexes. (C) 2000 Elsevier Science B.V.

Square pyramidal complexes [CuII(PFL)(bpa)Cl]{bullet operator}5H2O (1) and [CuII(LFL)(bpa)Cl]{bullet operator}5H2O (2) have been synthesized and characterized. Compounds were checked for their in-vitro antimicrobial activity against two Gram(+ ve) and three Gram(-ve) bacterial species. Intrinsic binding constant (Kb) of complexes with CT DNA were determined using absorption titration. Viscosity measurement suggests that complexes bind with CT DNA through partial nonclassical intercalative mode. Superoxide dismutase (SOD) like activity of the complexes was also compared with previously reported compounds.
