Health assessment is an important part of PHM technology, which is crucial to product state monitoring and management.With the complexity of product structure and diversification of functions, the product health presents uncertainty under the complex influence of multiple factors.Nowadays, the general health assessment method is relatively simple a
This work investigated the metabolites and their biosynthetic functional hydroxylase genes of the deep-sea sediment metagenomic clone 25D7.5-Bromoindole was added to the 25D7 clone derived Escherichia coli fermentation broth.The new-generated metabolites and their biosynthetic byproducts were located through LC-MS, in which the isotope peaks of bro
Here we describe the functionalization of lupulone natural compound in obtaining 3-isobutyl-5,5,7-tris(3-methylbut-2-en-1-yl)-1-phenyl-1,7-dihydro-4H-indazole-4,6(5H)-dione.The lupulone-H-indazole derivative was prepared with 75% yield through the reaction between lupulone and phenyl-hydrazine employing SiO2/ZnCl2 (30% m/m) as Dog Coats a support s
