The present study examined the cytotoxicity, anti-cancer reactivity, and immunomodulatory properties of new synthetically prepared fluoroquinolone derivative 6-fluoro-8-nitro-4-oxo-1,4-dihydroquinoline-3-carboxylate (6FN) in vitro. The cytotoxicity/toxicity studies (concentrations in the range 1...

L-Indospicine (Ind), a natural product amino acid analog of L-arginine, was synthesized from L-glutamic acid 2 in nine steps and 29% overall yield. Ind was evaluated as an alternative substrate or inhibitor of two nitric oxide synthase (NOS) isozymes. Ind did not act as either an alternative sub...

SummaryIn vitro studies with both liver homogenates and actively growing cells in culture have shown that indospicine, a structural analogue of arginine, can competitively inhibit arginine metabolism. In this report a further example of such an action is presented. Mouse bone marrow cells were c...

Indospicine is a natural toxin occurring only in Indigofera plant species, including the Australian native species I. linnaei. These perennial legumes are resistant to drought and palatable to grazing livestock including cattle. Indospicine accumulates in the tissues (including muscle) of animal...

Indospicine, a non-proteinogenic analogue of arginine, occurs only in Indigofera plant species and accumulates in the tissues of animals grazing on Indigofera. Canine deaths have resulted from the consumption of indospicine-contaminated meat but only limited information is available regarding in...

Effective long term stable anaesthesia is a goal of many drug regimens employed in neuroscience in which procedures carried out are not practical in awake animals. A particular problem is the study of nociceptive mechanisms where good anaesthesia is essential. Similarly studies of cardiovascular...

In spite of huge endeavors in cell line engineering to produce glycoproteins with desired and uniform glycoforms, it is still not possible in vivo. Alternatively, in vitro glycoengineering can be used for the modification of glycans. However, in vitro glycoengineering relies on expensive nucleot...

IntroductionInteractions of three copper(II) bis(thiosemicarbazone) positron emission tomography radiopharmaceuticals with human serum albumin, and the serum albumins of four additional mammalian species, were evaluated.

N-[(4-bromo-3,5-difluorine)phenyl]maleimide(BDPM) is a new monomer for polyreaction. Its densities and viscosities of BDPM + DMF(vol = 30%) + Toluene(vol = 70%) and BDPM + DMF(vol = 30%) + Ethanol(vol = 70%) have been determined experimentally under normal atmospheric pressure over the entire mo...

The objective of this paper is the study of the electrochemical oxidation of p-tert-butyl anisole in acetonitrile solution and its subsequent electrodeposition on platinum anode. In dry medium, potentiostatic deposition at potential more anodic than these of the two first overlapped waves, which...

Diastereomers of tert-butyl-N-Boc-3-ethyl-4-hydroxy-l-prolinate 1 and 2 have been synthesized in six steps starting from readily available Boc-protected trans-4-hydroxy-l-proline. The key reactions in the synthesis are asymmetric reductions, firstly on the 4-ketoproline intermediate 6 and second...

1S,2R-Indene oxide is the precursor of cis-1S,2R-aminoindanol, a key intermediate for the Merck HIV–1 protease inhibitor, Crixivan®. As an alternative to the challenging chemical synthesis of this chiral epoxide from indene, the biotransformation route using an enzyme catalyst was examined. App...

RésuméContexte et objectifL’augmentation de prévalence des troubles envahissants du développement est documentée dans la littérature internationale, mais les données restent parcellaires en France. L’objectif est d’analyser l’évolution récente des prévalences des TED à partir des ...

The 1-(6-(quinoxalin-2-yl)pyridin-2-yl)ethanone was synthesized in order to prepare a series of N-(1-(6-(quinoxalin-2-yl)pyridine-2-yl)ethylidene)benzenamines (L1–L7), which provided new alternative N∧N∧N tridentate ligands coordinating with iron(II) and cobalt(II) dichloride to form complexe...

Ethnopharmacological relevanceXian-Ling-Gu-Bao (XLGB) Fufang is an herbal formula that has been used in clinical settings to treat osteoporosis, osteoarthritis, aseptic bone necrosis, and climacteric syndrome. Despite its uses, XLGB treatment has been linked to potential liver injury. To date, t...

ABSTRACTObjective To predict the main active ingredients, potential targets and molecular mechanisms of Yuan Zhi powder in treatment of dementia by using network pharmacology.Methods A database of chemical constituents of Yuan Zhi powder was constructed by using databases and literatures. Potent...

Ling Zhi-8 (LZ-8), a novel immunomodulatory protein, markedly enhanced the expression of CDllb, but not CDlla, CD13, CD14, CD18, CD33 or HLA-DR, on the U937 cell line in a dose-dependent fashion. It also induced ICAM-1 expression on vascular endothelial cells and significantly augmented γ -inte...

Hot flashes are one of the main problems in postmenopausal patients. Hormone replacement therapy is the standard treatment for this vasomotor symptom, but long-term estrogen treatment can produce serious adverse effects such as higher risks of cardiovascular disease and breast cancer. For this r...

PurposeThis study evaluated the osteogenetic capability of Ling Zhi-8 (LZ-8; a protein purified from traditional Chinese medicine [lingzhi]) compared with recombinant human bone morphogenic protein-2 (rhBMP-2) in a standardized bony defect using a rabbit sinus model.

We recently reported that recombinant Ling Zhi-8 (rLZ-8), a medicinal mushroom Ganoderma lucidum recombinant protein, effectively prevents lung cancer cells proliferation in vivo mice model. In our current study, we demonstrated that rLZ-8 suppressed tumor metastasis and increased the survival r...
