Three new diarylheptanoids, (3S,5R)-3-hydroxy-5-methoxy-1,7-bis(4-hydroxyphenyl)-6E-heptene (1), (3S,5S)-3-hydroxy-5-methoxy-1,7-bis(4-hydroxyphenyl)-6E-heptene (2), and (3S)-3-hydroxy-1,7-bis(4-hydroxyphenyl)-6E-hepten-5-one (3), four new flavonoid glycosides, 3,7,3'-tri-O-methylquercetin-4'-O-β-d-apiofuranosyl-(1→2)-O-β-d-glucopyranoside (4), 7,3'-di-O-methylquercetin-4'-O-β-d-glucopyranosyl-...
From the aerial parts of Gutierrezia microcephala (Asteraceae), four oxyflavones were isolated, namely 5,7,2'-trihydroxy-3,6,8,4',5'-pentamethoxyflavone (1); 5,7,4'-trihydroxy-3,6,8-trimethoxyflavone (2); 5,7,2',4'-tetrahydroxy-3,6,8,5'-tetramethoxyflavone (3); 5,2'-dihydroxy-3,6,7,8,4',5'-hexamethoxyflavone (4), and an ent-clerodane, bacchabolivic acid (5). Compounds 1-5, the synthetic methyl ...
(14R)-14-Hydroxy-6-O-methylerythromycin A and (14S)-epimer have been isolated as active metabolites from human urine after oral administration of 6-O-methylerythromycin A (TE-031, A-56268). The structures of these metabolites were determined by means of mass, 1H and 13C NMR spectroscopies. Antimicrobial activities of (14R)-14-hydroxy-6-O-methylerythromycin A, a major metabolite, were comparable...
Similar to the 2006 consensus statement on the standardization of growth hormone (GH) assays (1 ), the guidelines regarding improvement of assay comparability in a recent consensus statement in Clinical Chemistry (2 ) are limitedto the recommendation to the recommendation of common use of the Second International Standard for Somatropin (IS 98/574), although it is recognized that discrepancies ...
Dysregulation of microRNAs (miRNAs) has been associated with malignant behavior in a variety of cancers. Our previous study demonstrated that miRNA expression profiles are predictors for patients with advanced non-small cell lung cancer (NSCLC). We also showed that miRNAs are involved in small-cell lung cancer metastasis. Here, we used qRT-PCR to re-analyze our previous microarray results using...
