Traditional herbal medicine consists of multiple components. There are interactions among the components, which affect both potency and toxicity. The preparation of herbal medicines can be a cause of interactions between multicomponents in herbs. To demonstrate the differences in multiherb interactions based on the preparation methods, the changes in the active components in the different preparations of Socheongryong-tang (SCRT) were evaluated using metabolomics profiling. We performed multicomponent profiling of the decoction of SCRT (SCRTD) and individual herb mixture (SCRTM) using ultra-high-performance liquid chromatog. coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS). Active compounds from SCRTD and SCRTM were identified using multivariate anal., and the activities between the two groups were compared. We also evaluated the anti-inflammatory effect of SCRT through investigating the protein expression of iNOS and COX-2 in lipopolysaccharide-induced macrophage RAW 264.7 cells in both groups. From the multivariate anal., 53 active compounds that have different intensities between SCRTD and SCRTM were identified. The intensities of those components, such as ephedrines, glycyrrhizic acid, 6-gingerol and (2E,4E,8Z,10E)-N-isobutyl-2,4,8,10-dodecatetraenamide, which is newly identified in Asiasarum heterotropoides, were mostly higher in SCRTD than in SCRTM, which was related to the anti-inflammatory effect. From the iNOS inhibition test, it was found that SCRTD had a stronger anti-inflammatory effect than SCRTM. It was demonstrated that multicomponent interactions can be changed by the preparation method, and finally the anti-inflammatory effect in SCRT can be affected. This study involved multiple reactions and reactants, such as (2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7Application In Synthesis of (2E,4E)-N-Isobutyldeca-2,4-dienamide).
(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. The amide group is called a peptide bond when it is part of the main chain of a protein, and an isopeptide bond when it occurs in a side chain, such as in the amino acids asparagine and glutamine. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.Application In Synthesis of (2E,4E)-N-Isobutyldeca-2,4-dienamide
