Rat liver fatty acid binding protein (L-FABP) was efficiently expressed in Escherichia coli and purified to homogeneity. The cDNA encoding L-FABP was ligated into the pTrc99A expression vector and expressed by induction with isopropyl-beta-d-thiogalactopyranoside under the control of the P(trc) promoter. Following an 18 h induction period, L-FABP(More)

Peroxide antimalarials, including artemisinin, are important for the treatment of multidrug-resistant malaria. These peroxides are known to react with iron or heme to produce reactive intermediates that are thought to be responsible for their antimalarial activities. This study investigated the potential interaction of selected peroxide antimalarials with(More)
There are numerous compilations of pKa values’’ in the physical chemistry literature, including several for pharmaceutically relevant organic weak acids and bases [1–8]. These are complemented by further compilations of pharmaceutically relevant physicochemical data such as partition coefficients, solubilities, and reaction rate constants [6]. At the same(More)
This paper reports the development of a reversed-phase high-performance liquid chromatographic assay for quantifying five of the most common sunscreen agents, namely 2-ethylhexyl-p-dimethyl aminobenzoate (Escalol 507), 2-ethylhexyl-p-methoxycinnamate (Parsol MCX); 4-tert.-butyl-4'-methoxydibenzoylmethane (Parsol 1789), 2-hydroxy-4-methoxybenzophenone-3(More)
The reaction of spiro- and dispiro-1,2,4-trioxolane antimalarials with heme has been investigated to provide further insight into the mechanism of action for this important class of antimalarials. A series of trioxolanes with various antimalarial potencies was found to be unreactive in the presence of Fe(III) hemin, but all were rapidly degraded by reduced(More)
Chlorpromazine is an antipsychotic agent with poor aqueous solubility. Complexation with SBE(7)-beta-CD can aid intravenous delivery through increasing the apparent solubility of chlorpromazine. However, chlorpromazine has also been known to self-associate. This self-association can influence its capacity to interact with other chemical species, such as(More)
We have determined the structure of the reduced form of the DsbA oxidoreductase from Vibrio cholerae. The reduced structure shows a high level of similarity to the crystal structure of the oxidized form and is typical of this class of enzyme containing a thioredoxin domain with an inserted alpha-helical domain. Proteolytic and thermal stability measurements(More)
Gene therapy by delivery of nonviral expression vectors is highly desirable, due to their safety, stability, and suitability for production as bulk pharmaceuticals. However, low transfection efficiency remains a limiting factor in application on nonviral gene delivery. Despite recent advances in the field, there are still major obstacles to overcome. In an(More)
CONTEXT Natural products play a vital role in the discovery of leads for novel pharmacologically active drugs. Geraniin (GE) was identified as the major compound in the rind of Nephelium lappaceum L. (Sapindaceae), while ellagic and gallic acids have been shown to be its main metabolites. GE and its metabolites possess a range of bioactive properties(More)
