Composition and stereochemistry of amorphispironone, a novel cytotoxic spironone kind rotenoid from Amorpha fruticosa
Get amorpha fruticosa leaf,, consider by weighing 2kg, be part of supercritical CO via pulverization process 2In the extractor, as entrainment agent, usage is twenty% of the medicinal product fat with ethanol, extracts, and extraction temperature is fifty ℃, and extracting pressure is 28MPa, CO 2Flow is 3ml/g crude drug/min, as well as extraction time is 4h, and separating nevertheless I temperature is 40 ℃, and force is 10MPa, and separating nonetheless II temperature is 35 ℃, and force is 7MPa, obtains extract, stirs with ETHYLE ACETATE and tends to make dissolving, filters, plus the filtrating focus drying receives crude extract; Undertake the Fake indigo spiral shell ketone inside the superior-speed countercurrent chromatography separation and purification crude extract, its two-phase solvent technique is petroleum ether-ethyl acetate-methanol-h2o, and quantity ratio is 8:3:7:3, on to fill While using the higher speed adverse existing chromatogram put up mutually be stationary section; Rotate main body, pump into down and do moving phase mutually, shifting stage is dissolved crude extract with the sampling valve sample introduction, the UV-detector on-line monitoring; The detection wavelength is 209nm, collects Fake indigo spiral shell ketone part, vacuum concentration; Separate out crystallization, leach crystallization, include the dissolving of eighty% methanol eddy; Position recrystallization, filtration, washing are drying to get Wrong indigo spiral shell ketone, written content ninety six.2%. Embodiment 4:
Get amorpha fruticosa leaf,, just take by weighing 1kg, join supercritical CO as a result of pulverization approach 2In the extractor, as entrainment agent, use is 18% of a medicinal substance fat with ethanol, extracts, and extraction temperature is thirty ℃, and extracting stress is 32MPa, CO 2Flow is 4ml/g crude drug/min, as well as extraction time is 3.5h, and separating even now I temperature is thirty ℃, and stress is 8MPa, and separating continue to II temperature is 28 ℃, and stress is 7MPa, obtains extract, stirs with ETHYLE ACETATE and will make dissolving, filters, as well as the filtrating concentrate drying will get crude extract; Undertake the false indigo spiral shell ketone while in the high-speed countercurrent chromatography separation and purification crude extract, its two-stage solvent procedure is petroleum ether-ethyl acetate-methanol-water, and volume ratio is 6:one:five:one, on to fill With all the superior velocity adverse existing chromatogram submit mutually be stationary section; Rotate main frame, pump into down and do shifting stage mutually, transferring period is dissolved crude extract by the sampling valve sample introduction, the UV-detector on-line checking; The detection wavelength is 209nm, collects false indigo spiral shell ketone component, vacuum concentration; Separate out crystallization, leach crystallization, add the dissolving of 80% methanol eddy; Put recrystallization, filtration, washing are drying to acquire Untrue indigo spiral shell ketone, material 97.four%. Embodiment three:

The invention belongs to the traditional Chinese drugs extraction separation know-how subject, relate into a Amorphispironone type of method for making ready Wrong indigo spiral shell ketone of from amorpha fruticosa leaf, separating.
We have now also incorporated the ligand similarity Evaluation in our study. The similarity analysis is predicated to the Tanimoto coefficient involving the two selected compounds and the reference inhibitor. The ChemMine Applications Website server is used to analyse the similarity between little molecules (Backman et al.

Principal element Assessment (PCA) is a powerful process for evaluating structural dynamics and collective motions in protein–ligand devices (Stein et al.
A protein framework community (PSN) Investigation was performed to analyze the networks of interacting amino acid residues to comprehend the protein security as well as function of structurally and functionally important residues. We've got predicted the hubs and communities of The real key interacting residues of the ITK-ligand complexes. PSN depicts the structure of proteins like a network, with nodes displaying amino acids and edges for their interactions.
A novel cytotoxic spironone style rotenoid, amorphispironone 1 has become isolated from the leaves of Amorpha fruticosa
