The regiochemical control of the ring opening of epoxides bearing polar remote functionalities, through chelation processes assisted by metal ions, was verified in the title compound (4).The use of metal assisted procedures in several ring opening reactions of 4 leads to a modification of the regiochemical outcome, and the attack of the nucleophile on the C-4 oxirane carbon is highly favored.

On the basis of qualitative structure-activity relationships developed in the preceding article, a series of 32 new mitomycin A analogues were prepared and tested in antitumor screens. Seven of them gave greater prolongation of life (ILS) than mitomycin C in the mouse P388 leukemia assay. They included examples with 7-O substituents such as cyclic ethers and nitrogen heterocycles. A Hansch analysis was attempted with log P and MR as the independent variables, but no statistically significant correlation could be made. Seven compounds, chosen mainly for their good potency (MED), were tested in the subcutaneous B16 melanoma assay in mice and four of them showed greater ILS than mitomycin C.

Lactoferrin is a non-heme iron-binding glycoprotein with multiple health-beneficial functions including antimicrobial, antioxidant, anticarcinogenic, and immunomodulatory effects. There is emerging evidence that neutrophils may serve as targets of lactoferrin in vivo, and here we show how recombinant human lactoferrin (rhLf) can contribute to this regulation. Indeed, our results demonstrate that rhLf binds efficiently to human neutrophils and induces a variety of early cellular responses such as mobilization of intracellular Ca2+, remodeling of actin cytoskeleton, and degranulation (release of lysozyme and myeloperoxidase). In addition, rhLf facilitates lectin-induced H2O2 production and stabilization of lectin-induced cellular aggregates. The role of calcium signaling seems to be essential for rhLf-induced activation of neutrophils, as Ca2+-chelators inhibit degranulation response while lectin-induced H2O2 production correlates significantly with cytoplasmic Ca2+ elevation. Taken together, our findings justify that rhLf can activate neutrophil functions in a calcium-dependent manner and hence, can potentiate innate immune responses.

Herein we describe the synthesis of a series of new potent tachykinin NK2 receptor antagonists by the modulation of the Cand N-terminal moieties of ibodutant (MEN 15596, 1). The Nterminal benzo[b]thiophene ring was replaced by different substituted naphthalenes and benzofurans, while further modifications were evaluated at the C-terminal tetrahydropyran moiety. Most compounds demonstrated a high affinity for the human NK2 receptor and high in vitro antagonist potency, indicating that a wide range of substituents at both termini can be incorporated in the molecule without detrimental effects on the interactions with the NK2 receptor. Selected compounds were tested in vivo confirming their activity as NK2 antagonists. In particular, after both iv and id administration to guinea pig, compound 61b was able to antagonize NK2-induced colonic contractions with a potency and duration-of-action fully comparable to the reference compound 1 (MEN 15596, ibodutant).

Enzymatic synthesis of trisaccharides from N-acetylsucrosamine and lactose utilizing the transgalactosylation activity of Aspergillus oryzae beta-galactosidase provided two reaction products. Structure analyses by various 2D NMR spectroscopy and MS indicated that the products were beta-D-fructofuranosyl beta-D-galactopyranosyl-(1?6)-2-acetamido-2-deoxy-alpha-D-glucopyranoside and beta-D-galactopyranosyl-(1?6)-beta-D-fructofuranosyl-(2?1)-2-acetamido-2-deoxy-alpha-D-glucopyranoside. Moreover, J-resolved-HMBC experiments indicated that the conformations around the glycosidic bonds of these trisaccharides were very similar. Examination about the pH and thermal stabilities of the glycosidic bonds in the GlcNAc?Fru moiety of the two trisaccharides indicated apparent difference.

We measured the affinity of more than 20 sugars with concanavalin A (ConA) by an optical biosensor (surface plasmon resonance sensor) using asialofetuin (ASF) as an immobilized binding partner of ConA. We determined kinetic parameters of the effects of sugars on the dissociation of ConA from ASF quantitatively, and the structural requirements of the functional groups of sugars for binding with ConA. We found that the affinity of ConA for sugars is dependent on its conformation induced by interaction with the binding partner. In addition, the results showed that optical biosensor system is well mimics the interaction of ConA with sugars in biomembrane.
