New 5,5-diethylbarbiturate (barb) complexes of Ni(ii), Cu(ii) and Zn(ii) with 1,10-phenanthroline (phen) and 2,2?-dipyridylamine (dpya), namely [Ni(phen-kappaN,N?)3]Cl(barb)¡¤7H2O (1), [Cu(barb-kappaN)(barb-kappa2N,O)(phen-kappaN,N?)]¡¤H2O (2), [Cu(barb-kappaN)2(phen-kappaN,N?)] (2a), [Zn(barb-kappaN)2(phen-kappaN,N?)]¡¤H2O (3), [Ni(barb-kappa2N,O)(dpya-kappaN,N?)2]Cl¡¤2H2O (4), [Cu(barb-kappa2N,O)2(dpya-kappaN,N?)]¡¤2H2O (5) and [Zn(barb-kappaN)2(dpya-kappaN,N?)] (6), were synthesized and characterized by elemental analysis, UV-vis, FT-IR and ESI-MS. The structures of the complexes were determined by X-ray crystallography. Notably, 3 and 6 were fluorescent in MeOH:H2O at rt. The interaction of the complexes with fish sperm (FS) DNA and bovine serum albumin (BSA) was investigated in detail by various techniques. The complexes exhibited groove binding along with a partial intercalative interaction with DNA, while the hydrogen bonding and hydrophobic interactions played a major role in binding to BSA. It is noteworthy that 2 exhibited the highest affinity towards DNA and BSA. Enzyme inhibition assay showed that 1-4 show a preference for both A/T and G/C rich sequences in pUC19 DNA, while 5 and 6 display a binding specificity to the G/C and A/T rich regions, respectively. These findings were further supported by molecular docking. The cellular uptake studies suggested that 2 was deposited mostly in the membrane fraction of the cells. Among the present complexes, 2 exhibited a very strong cytotoxic effect on A549, MCF-7, HT-29 and DU-145 cancer cells, being more potent than cisplatin. Moreover, 2 induces cell death through the apoptotic mode obtained by flow cytometry.

Installation of electron-donating protective groups, a strategy for glycosylating unreactive thioglycosyl acceptors using the preactivation-based glycosylation method

(Chemical Equation Presented) Preactivation-based chemoselective glycosylation is a powerful strategy for oligosaccharide synthesis with its successful application in assemblies of many complex oligosaccharides. However, difficulties were encountered in reactions where glycosyl donors bearing multiple electron-withdrawing groups failed to glycosylate hindered unreactive acceptors. In order to overcome this problem, it was discovered that the introduction of electron-donating protective groups onto the glycosyl donors can considerably enhance their glycosylating power, leading to productive glycosylations even with unreactive acceptors. This observation is quite general and can be extended to a wide range of glycosylation reactions, including one-pot syntheses of chondroitin and heparin trisaccharides. The structures of the reactive intermediates formed upon preactivation were determined through low-temperature NMR studies. It was found that for a donor with multiple electron-withdrawing groups, the glycosyl triflate was formed following preactivation, while the dioxalenium ion was the major intermediate with a donor bearing electron-donating protective groups. As donors were all cleanly preactivated prior to the addition of the acceptors, the observed reactivity difference between these donors was not due to selective activation encountered in the traditional armed-disarmed strategy. Rather, it was rationalized by the inherent internal energy difference between the reactive intermediates and associated oxacarbenium ion like transition states during nucleophilic attack by the acceptor.

Stereoselective synthesis of cyclopropanes based on a 1,2-chirality transfer

A stereoselective route to enantiomerically enriched bicyclic cyclopropane derivatives 13 is described which is based on a conceptually novel 1,2-chirality transfer approach. The hyperconjugative interaction of an electronically excited carbonyl group with the sigma* orbital of an adjacent C-X bond in the transition state of a hydrogen abstraction causes the preference of a certain conformation and consequently the differentiation between two diastereotopic methylene groups. The 1,2-chirality transfer is completed by a subsequent HX elimination which destroys the only stereogenic center in the reactants 12. Furthermore, it was found that contrary enthalpic and entropic influences result in the existence of an inversion temperature T0. Upon crossing T0 the stereoselectivity is reversed. Considering this temperature dependency, chirality transfer efficiencies of up to 83% could be achieved. The absolute configuration of most products could be unambiguously determined by VCD spectroscopy combined with DFT calculations.

1,2,3-Triazole-containing uracil derivatives with excellent pharmacokinetics as a novel class of potent human deoxyuridine triphosphatase inhibitors

Deoxyuridine triphosphatase (dUTPase) has emerged as a potential target for drug development as a 5-fluorouracil-based combination chemotherapy. We describe the design and synthesis of a novel class of human dUTPase inhibitors, 1,2,3-triazole-containing uracil derivatives. Compound 45a, which possesses 1,5-disubstituted 1,2,3-triazole moiety that mimics the amide bond of tert-amide-containing inhibitor 6b locked in a cis conformation showed potent inhibitory activity, and its structure-activity relationship studies led us to the discovery of highly potent inhibitors 48c and 50c (IC50 = ?0.029 muM). These derivatives dramatically enhanced the growth inhibition activity of 5-fluoro-2?-deoxyuridine against HeLa S3 cells in vitro (EC50 = ?0.05 muM). In addition, compound 50c exhibited a markedly improved pharmacokinetic profile as a result of the introduction of a benzylic hydroxy group and significantly enhanced the antitumor activity of 5-fluorouracil against human breast cancer MX-1 xenograft model in mice. These data indicate that 50c is a promising candidate for combination cancer chemotherapies with TS inhibitors.
