    Structurally diverse lignans from <i>Solanum lyratum</i>: chemical evidence for their acetylcholinease inhibitory activity

    No full text
    A chemical investigation of Solanum lyratum Thumb. (Solanace) afforded two new lignans (1b and 3) and eleven known lignan analogues (1a, 2a/2b and 4–11). Compounds 1a/1b and 2a/2b were separated as two pairs of enantiomers by chiral high-performance liquid chromatography (HPLC). Their structures were elucidated by detailed spectroscopic and comparative literature data analysis. The absolute configurations of compounds 1a/1b and 2a/2b were determined by comparing the experimental ECD data with the calculated values. All compounds were evaluated for their acetylcholinesterase (AChE) inhibitory activity. Notably, compared to the positive control, compounds 4 and 9 showed obvious AChE inhibition with their IC50 values of 1.30 ± 0.25 and 0.89 ± 0.04 μM, respectively. In addition, the possible interaction between acetylcholinesterase and the active compounds was also investigated by molecular docking.</p

    †Electrorubesopsinae, a new subfamily from Cretaceous Burmese amber, as the possible sister group of Dynamopodinae (Coleoptera: Scarabaeidae)

    <p>A new subfamily of Scarabaeidae, †Electrorubesopsinae Bai & Wang subfam. nov., is described from Cretaceous amber of Myanmar (earliest Cenomanian, ∼100 Ma) as the possible sister group of Dynamopodinae. †<i>Electrorubesopsis beuteli</i> Bai & Wang gen. et sp. nov. is the first species of this subfamily, which has probably been long extinct. Its external morphology was analysed and compared with all known genera of Dynamopodinae. A phylogenetic analysis based on 82 morphological characters suggests its placement in a sister relationship between †<i>Electrorubesopsis</i> and <i>Orubesa</i>. The hypothesis of a close relationship between <i>Orubesa</i> (Dynamopodini) and <i>Thinorycter</i> (Thinorycterini) is challenged. †<i>Electrorubesopsis</i> likely lived in a sandy environment or forest.</p> <p><a href="http://zoobank.org/urn:lsid:zoobank.org:pub:15351B5E-337C-49D4-90F0-619269BD1E5A" target="_blank">http://zoobank.org/urn:lsid:zoobank.org:pub:15351B5E-337C-49D4-90F0-619269BD1E5A</a></p

    Cytotoxic lignans from the barks of <i>Juglans mandshurica</i>

    No full text
    <p>Phytochemical investigation of the barks of <i>Juglans mandshurica</i> Maxim led to the isolation, purification, and identification of one new lignan named Juglansol A (<b>1</b>), along with nine known compounds (<b>2–10</b>). Their structures were determined by the results of UV, IR, CD, HRESIMS, 1D, and 2D NMR spectroscopic analysis. Compounds <b>1–10</b> were evaluated for their cytotoxicities against A549, HepG2, Hep3B, Bcap-37, and MCF-7 cell lines. The results showed that compound <b>2</b> possessed stronger cytotoxicities against the tested tumor cell lines compared with positive control 5-fluorouracil.</p

    Expanded Application of Piper nigrum: Guided Isolation of Alkaloids with Inhibitory Activities of AChE/BuChE and Aβ Aggregation

    No full text
    Piper nigrum is a popular crop that can be used as seasoning or as an additive but its active ingredients also have an effect on the nervous system. Nineteen new amide alkaloids (1a/1b, 2–5, 6a/6b, 7, 8a/8b, 9, 10a/10b, 11a–11b, 12–14) were isolated from P. nigrum, guided by inhibitory activity of AChE and LC–MS/MS based on GNPS. The configurations were determined by extensive spectral analysis, Bulkiness rule, and NMR calculations. The inhibitory activities of AChE/BuChE and Aβ aggregation were tested, and the results showed compounds 2, 7, and 12 had significant inhibitory activities. These components were identified in the crude fraction and their relative quantities were tested, which suggested that compound 2 was the index component in the active site from P. nigrum
