The preparation of new phosphorus-centered functional groups for modified oligonucleotides and other natural phosphates. (1/10)

Efforts to develop synthetic methodologies allowing the preparation of alpha,alpha- difluorophosphonothioates, alpha,alpha-difluorophosphonodithioates, alpha,alpha-difluorophosphono- trithioates, and alpha,alpha-difluorophosphinates are reviewed in the light of applications in the field of modified oligonucleotides and cyclitol phosphates. Two successful approaches have been developed, based either on the addition of phosphorus-centered radicals onto gem-difluoroalkenes or on a process involving the addition of lithiodifluorophosphono- thioates 91 onto a ketone and the subsequent deoxygenation reaction of the adduct. The radical route successfully developed a practical route to alpha,alpha-difluoro-H-phosphinates which proved to be useful intermediates to a variety of phosphate isosters. The ionic route led to the first preparation of phosphonodifluoromethyl analogues of nucleoside- 3'-phosphates.  (+info)

Hypoglycemic effect of 13-membered ring thiocyclitol, a novel alpha-glucosidase inhibitor from Kothala-himbutu (Salacia reticulata). (2/10)

A novel 13-membered ring thiocyclitol, isolated from an aqueous extract of Kothala-himbutu (Salacia reticulata), inhibited alpha-glucosidase in vitro. The inhibitory activity was investigated by maltose- and sucrose-loading on Wistar rats. This study found significant lowering of postprandial glucose levels, and the potency of 13-membered ring thiocyclitol was confirmed in vivo.  (+info)

Although most cases do not require further hospitalization, influenza periodically causes epidemics in humans that can potentially infect and kill millions of people. To countermeasure this threat, new vaccines need to be developed annually to match emerging influenza viral strains with increased resistance to existing vaccines. Thus, there is a need for finding and developing new anti-influenza viral agents as alternatives to current treatments. Here, we tested the antiviral effects of an extract from the stems and ...
One of the biggest hurdles in the fight against cancer is the non‐selective nature of most current treatments. On the other hand, opioids‐refractive cancer pain is a most important unsolved problem. Consequently, the search and development of new drugs that are tumor‐killing (while non‐cytotoxic to normal cells) and/or potent analgesics are major goals in cancer research. In this context, pancratistatin and tetrodotoxin, the most prominent representatives of two different families of natural products, have been identified as highly promising leads for cancer treatment and cancer pain, respectively; in fact, they are currently at the focus of some initiatives for pharmaceutical development.. Interest in pancratistatin stems from its high level of in vitro and in vivo cell growth inhibitory activity on a wide variety of human cancer cell lines, but particularly from its mode of action that, while yet unknown, is very selective: pancratistatin does not affect normal cells in clear contrast ...

To study the cost of chromosomal drug resistance mutations to bacteria, we investigated the fitness cost of mutations that confer resistance to different classes of antibiotics affecting bacterial protein synthesis (aminocyclitols, 2-deoxystreptamines, macrolides). We used a model system based on an in vitro competition assay with defined Mycobacterium smegmatis laboratory mutants; selected mutations were introduced by genetic techniques to address the possibility that compensatory mutations ameliorate the resistance cost. We found that the chromosomal drug resistance mutations studied often had only a small fitness cost; compensatory mutations were not involved in low-cost or no-cost resistance mutations. When drug resistance mutations found in clinical isolates were considered, selection of those mutations that have little or no fitness cost in the in vitro competition assay seems to occur. These results argue against expectations that link decreased levels of antibiotic consumption with the ...

Alkaloids pancratistatin and narciclasine, isolated from Amaryllidaceae, have been shown to present antitumor activity on preclinical models, including melanoma. Despite extensive investigations, pancratistatin or narciclasine analogues did not succeed to provide sufficient therapeutic benefit, [1] mostly hampered by poor water solubility and systemic toxicity [1]. To overcome those limitations, we developed a chemistry program aimed at improving both their physicochemical and pharmacological properties. A literature survey suggests that any structural modification of this highly oxigenated isocarbostiryl specific scaffold would lead to a loss of activity except on position 1, difficult to achieve but interesting to explore.. A series of 40 novel 1-aminopancratistatin derivatives was synthesised starting from large quantities of narciclasine extracted from Narcissus bulbs. These novel compounds exhibit an improved pharmaceutical profile facing standard solubility, plasmatic and microsomal ...

Coloured scanning electron micrograph (SEM) of Streptomyces hygroscopicus, Gram-positive, aerobic, filamentous, biofilm-forming, rod prokaryote (bacterium). Streptomyces sp. belong to the Actinomycetes group and are bacteria that share many characteristics with the fungi. They grow usually as filaments (chains of cells) and often branch to form a network of filaments (mycelium) in the soil. These soil bacteria are responsible for the musty odour of soil. This strain of Streptomyces hygroscopicus produces the antibiotic, milbemycin, which is used as an insecticide and also to control certain parasitic infections in animals. It is also a biofilm forming bacterium. Biofilms are primarily accumulations of bacteria in aqueous environments. They form when bacteria secrete slimy, mucilaginous materials that provide the microorganisms with a means of attachment to moist surfaces.

TY - JOUR. T1 - Synthesis of natural products utilizing ring cleavage reaction of myo-inositol derivatives. AU - Chida, Noritaka. PY - 2000/7. Y1 - 2000/7. N2 - myo-Inositol, a cyclitol (cyclohexanepolyol) which is classified as a type of carbohydrates, occurs widely in nature and is known as a constituent of a secondary messenger in cells which stimulates the release of calcium from storage site. It is produced in large quantities from plants (rice bran and corn-steep liquors) by food industry. In spite of its abundance in nature and ready availability, myo-inositol has not been utilized widely as the starting material for the synthesis of natural products other than cyclitol derivatives. Given that regioselective ring cleavage of the cyclohexane ring in optically active and functionalized cyclitol derivatives is possible, myo-inositol is expected to be a potential precursor with stereochemical diversity for novel chiral building blocks in the synthesis of various natural products. In this ...

α-GalCer is a strong immunostimulatory molecule that holds great promise for antitumor therapeutic purposes and vaccine development (3, 7, 38). However, several concerns limit its use in clinics, including the uncontrolled response it promotes when delivered in a nonvectorized form. Cell-based antitumor therapy (transfer of DCs pulsed with α-GalCer) to better control iNKT cell functions is an attractive possibility (6, 7), although this procedure remains complex and expensive. Another strategy is to passively or actively deliver α-GalCer to DCs. We and others have shown that α-GalCer vectorized in PLGA-based NPs (30), silica particles (39), liposomes (40), or included into virus-like particles (41) activated iNKT cells but failed to prevent their hyporesponsiveness upon restimulation, a likely consequence of uncontrolled cell targeting. Therefore, a controlled delivery of α-GalCer is a requisite to optimize iNKT cell responses. A recent study showed that specific targeting of α-GalCer to ...

  • A method for the production of a cyclitol of increased purity is disclosed. (avl-labs.com)
  • The method includes extracting the cyclitol from a plant material with an extractant to form a cyclitol extract and forming a cyclitol source from the cyclitol extract and having a cyclitol purity P1. (avl-labs.com)
  • The method also includes (step b) contacting the cyclitol source with an extractant medium to form at least one solvent-rich stream with an increased cyclitol purity P2 and at least one solvent-poor stream with a reduced cyclitol purity P3 so that P2 is greater than each of P1 and P3. (avl-labs.com)
  • The method also includes subjecting the solvent-rich stream resulting from step (b) to an enrichment operation to form a cyclitol-enriched stream having a purity P4 and a cyclitol-depleted stream with a purity P5 so that P4 is greater than each of P2 and P5. (avl-labs.com)
