Cell wall invertase immobilization within calcium alginate beads
(Elsevier, 2007)
Yeast cell wall invertase (CWI) was immobilized within calcium alginate beads. The result of entrapment was the complete immobilization of all the added CWI. Three types of biocatalysts were prepared: CWI-S, CWI-155 and ...
Supercritical carbon dioxide extraction of antioxidant fractions from selected Lamiaceae herbs and their antioxidant capacity
(Elsevier Sci Ltd, Oxford, 2010)
Antioxidant fractions from four herb spices belonging to the Lamiaceae family: rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris) and hyssop (Hyssop officinalis) were isolated using ...
Alumina/silica supported K2CO3 as a catalyst for biodiesel synthesis from sunflower oil
(Elsevier Sci Ltd, Oxford, 2009)
The new type of catalyst for fatty acid methyl esters (FAME or biodiesel) synthesis with K2CO3 as active component on alumina/silica support was synthesized using sol-gel method. Corresponding catalyst (xerogel) was prepared ...
Catalytic activity of Pt catalysts promoted by MnOx for n-hexane oxidation
(Elsevier, 2011)
The deep oxidation of n-hexane was studied over Pt catalysts with small and large Pt crystallites, promoted by MnOx. The Mn was deposited on the Pt/Al2O3 by deposition-precipitation method using two alkalis, ammonia and ...
Immobilization of Cell Wall Invertase Modified with Glutaraldehyde for Continuous Production of Invert Sugar
(American Chemical Society (ACS), 2010)
Yeast cell wall invertase (CWI) was modified with dimethyl suberimidate, glutaraldehyde, formaldehyde, and sodium periodate. Retained activity after modification was 45% for CWI modified with formaldehyde, 77% for CWI ...
A refined pharmacophore identifies potent 4-amino-7-chloroquinoline-based inhibitors of the botulinum neurotoxin serotype A metalloprotease
(American Chemical Society (ACS), 2007)
We previously identified structurally diverse small molecule (non-peptidic) inhibitors (SMNPIs) of the botulinum neurotoxin serotype A (BoNT/A) light chain (LC). Of these, several (including antimalarial drugs) contained ...
Determination of glass temperature of polymers by inverse gas chromatography
(Elsevier, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
Novel 4-aminoquinolines active against chloroquine-resistant and sensitive P. falciparum strains that also inhibit botulinum serotype A
(American Chemical Society (ACS), 2008)
We report on the initial result of the coupling of 4-amino-7- chloroquinoline with steroidal and adamantane constituents to provide small molecules with excellent in vitro antimalarial activities (IC90 (W2) down to 6.74 ...
New chimeric antimalarials with 4-aminoquinoline moiety linked to a tetraoxane skeleton
(American Chemical Society (ACS), 2008)
The synthesis of the chimeric molecules consisting of two pharmacophores, tetraoxane and 7-chloro-4-aminoquinoline, is reported. The tetraoxanes 2, 4, and 8 show relatively potent in vitro antimalarial activities, with ...
Synthesis and antioxidant properties of fullero-steroidal covalent conjugates
(Oxford : Pergamon-Elsevier Science Ltd, 2007)
Four new fullero-steroids were synthesized starting from gamma-aminobutyric acid (GABA)-incorporated fulleropyrrolidine and corresponding sterols. The synthesis, characterization, preliminary study on in vitro antioxidant ...
