A novel electrochemiluminescence (ECL) detector is presented in this article. The detector is applied for micellar electrokinetic chromatographic separation of dichlorotris(2,2′-bipyridyl)ruthenium(II) hydrate [Ru(bpy)] and dichlorotris(1,10-phenanthroline ...
Therapeutic value of the alkylating agent ifosfamide has been limited by major side effects including encephalopathy. Although the underlying biochemical processes of the neurotoxic side effects are still unclear, they could be attributed to metabolites ra ...
Two representatives of a new type of beta-amino acids, carrying two functionalized side chains, one in the 2- and one in the 3-position, have been prepd. stereoselectively: a beta-Ser deriv. with an addnl. CH2OH group in the 2-position, for beta-peptides w ...
Analogues of the opioid peptides [D-Phe(3)]morphiceptin (H-Tyr-Pro-D-Phe-Pro-NH2) and endomorphin-2 (H-Tyr-Pro-Phe-Phe-NH2) containing the pseudoproline (Psi Pro) (4R)-thiazolidine-4-carboxylic acid (CyS[Psi (R1,R2) pro]) or (4S)-oxazolidine-4-carboxylic a ...
The inter- and intramol. interactions between the different domains of the catalase-peroxidase KatG from Mycobacterium tuberculosis were analyzed using the two-hybrid assay. It was shown that the dimerization of the enzyme is due to a strong interaction of ...
A process is provided for the in-situ extn. of a fermn. product esp. for products which result from the transformation of an amino acid and which are sol. in the fermn. broth. The sol. product is then removed from aq. phase by extn. into an org. phase wher ...
We have isolated a novel protein kinase cDNA, PfPK6, by differential display RT-PCR (DDRT-PCR) of mRNA obtained from different asexual erythrocytic stages of Plasmodium falciparum, which shows sequence similarity to both cyclin-dependent kinase (CDK) and m ...
Comprehensive and cGMP suitable bioprocess monitoring is still a challenge in microbial fermn. and cell culture process development. This paper discusses the exploitation of in-situ mid-IR spectroscopy in combination with partial least-squares anal. to mon ...
After administration of enriched [1-13C]glucose, the rate of 13C label incorporation into glutamate C4, C3, and C2, glutamine C4, C3, and C2, and aspartate C2 and C3 was simultaneously measured in six normal subjects by 13C NMR at 4 Tesla in 45-ml volumes ...
Intrastriatal injection of quinolinic acid (QA) provides an animal model of Huntington disease. In vivo 1H NMR spectroscopy was used to measure the neurochemical profile non-invasively in seven animals 5 days after unilateral injection of 150 nmol of QA. C ...
