RESUMEN

The 1-DNJ named 1-deoxynojirimycinis (2R,3R,4R,5S)-2-(hydroxymethyl) piperidine-3,4,5-triol, which is the nature active components existingin mulberryresources including leaves, stems, roots and silkworm larva, silkworm chrysalis, etc.The 1-deoxynojirimycin is a polyhydroxylated piperidine alkaloid, which was first found in Streptomyces as an antibiotic. Then the Japanese researchers isolated it from the mulberry root. 1-DNJ can inhibit postprandial hyperglycemia by suppressing intestinal alpha glucosidase. Therefore, 1-DNJ is often used to treat treating diabetes and complicating disease and to prevent obesity and weight-related disorders. With the development of the researches, 1-deoxynojirimycin and its derivtiv was discovered to possess anti-hyperglycemic, anti-virus, anti-tumor functions and so on. Therefore,based on our current studythe existing knowledge on source, technique preparation process, pharmacokinetics, bioactivties,and in silico target fishing of 1-DNJ were summarized, so that the researchers may use it to explore future perspective of research on 1-DNJ.

RESUMEN

The present study was designed to target fish for potential bioactive components contained in a Huang Lian Jie Du decoction (HLJDD) and identify the underlying mechanisms of action for the treatment of sepsis at the molecular level. he bioactive components database of HLJDD was constructed and the sepsis-associated targets were comprehensively investigated. The 3D structures of the PAFR and TXA2R proteins were established using the homology modelling (HM) method, and the molecular effects for sepsis treatment were analysed by comparing the bioactive components database and the sepsis targets using computational biology methods. The results of the screening were validated with biological testing against the human oral epidermal carcinoma cell line KB in vitro. We found that multiple bioactive compounds contained in the HLJDD interacted with multiple targets. We also predicted the promising compound leads for sepsis treatment, and the first 28 compounds were characterized. Several compounds, such as berberine, berberrubine and epiberberine, dose-dependently inhibited PGE2 production in human KB cells, and the effects were similar in the presence or absence of TPA. This study demonstrates a novel approach to identifying natural chemical compounds as new leads for the treatment of sepsis.
