Angiogenic effect of motherwort (Leonurus japonicus) alkaloids and toxicity of motherwort essential oil on zebrafish embryos.[Pubmed: 29729400]
There is growing evidence that motherwort (Leonurus japonicus Houtt.), and Chinese patent medicines derived from motherwort, alleviate postpartum uterine subinvolution, as well as the effects on myocardial and cerebral ischemic injuries. We hypothesized that these beneficial effects of motherwort may be related to angiogenesis. To test this hypothesis, we investigated the angiogenic effects of motherwort total alkaloids and essential oil, as well as their respective primary components, on zebrafish embryos. Motherwort total alkaloids significantly increased angiogenesis in transgenic Tg (flk1: EGFP) zebrafish embryos treated with sunitinib, as did stachydrine, the most abundant alkaloid produced by motherwort. Unexpectedly, motherwort essential oil was toxic to zebrafish embryos. Our results indicated, for the first time, that motherwort alkaloids were potent angiogenic agents, while even low concentrations of motherwort essential oil were toxic. As angiogenesis is a critical aspect of postpartum recovery, our results provide evidence for traditional application of motherwort water decoction and its Chinese patent medicines (e.g. motherwort injection) to promote postpartum recovery.
A new labdane-type diterpenoid from Leonurus japonicus.[Pubmed: 29683345]

New diterpenoids isolated from Leonurus japonicus and their acetylcholinesterase inhibitory activity.[Pubmed: 29329613]
Three new labdane diterpenoids, leojaponicone A (1), isoleojaponicone A (2) and methylisoleojaponicone A (3), were isolated from the herb of Leonurus japonicus. The chemical structures of these secondary metabolites were elucidated on the basis of 1D and 2D NMR, including HMQC, and HMBC spectroscopic techniques. All the new compounds were tested in vitro for their acetylcholinesterase and α-glucosidase inhibitory activity. Compounds 1-3 exhibited low inhibitory effects on α-glucosidase with respect to acarbose and exhibited high inhibitory effects on acetylcholinesterase with respect to huperzine A.

Alkaloids and flavonoid glycosides from the aerial parts of Leonurus japonicus and their opposite effects on uterine smooth muscle.[Pubmed: 29127939]
The crude extract and some Chinese patented medicines of Leonurus japonicus Houtt. have been proven to affect the uterine smooth muscle. L. japonicus injection is widely used in obstetric departments in China for treating postpartum hemorrhage caused by uterine inertia. Bioassay-guided isolation of the 95% EtOH extract of L. japonicus yielded four cyclopeptides, nine alkaloids, and three flavonoid glycosides, including two previously undescribed cyclopeptides, namely, cycloleonuripeptide G and cycloleonuripeptide H. The structures of the cyclopeptides were elucidated to be cyclo-(L-Phe-L-Phe-Gly-L-Pro-Gly-L-Pro) and cyclo-(L-Phe-L-Ala-L-Pro-L-Ile-L-His-Gly-L-Ala-L-Pro), respectively, via spectroscopic and chemical methods. Cyclopeptides (cycloleonuripeptides C and D) and alkaloids (imperialine-3β-D-glucoside and leonurine) promoted contraction of uterine smooth muscle strips isolated from normal rats. However, it was observed that flavonoid glycosides (spinosin, linarin, and apigenin-7-O-β-D-glucopyranoside) significantly inhibited contraction of the uterine smooth muscle strips.
[Optimize concentrate process of alkaloid from Leonurus japonicus by ultrafultration-nanofiltration coupling technology].[Pubmed: 28945032]
To optimize the concentrate process of alkaloid from Leonurus japonicus by nanofiltration-ultrafiltration coupling technology with response surface methodology. The experiment showed that after ultrafiltration pre-treatment, the total protein removal rate was 94.38% in aqueous extract from L. japonicus, and the nanofiltration technology had obvious advantages over the conventional concentrate process. The optimal concentrate conditions were as follows：molecular weight cut-off 450, pH 3.07, concentration of stachydrine hydrochloride 80.15 mg•L⁻¹, and concentration of the total alkaloid 285.73 mg•L⁻¹. The cut-off rate was 93.37% and 95.85% respectively for stachydrine hydrochloride and the total alkaloid under the optimum conditions, with a relative error of 0.79% and 1.16% respectively. The combination of Box-Behnken design and response surface analysis can well optimize the concentrate process of L. japonicus by nanofiltration, and the results provide the basis for nanofiltration concentrate for heat-sensitive traditional Chinese medicine.
Soluble epoxide hydrolase inhibitory activity of components from Leonurus japonicus.[Pubmed: 28501602]
One new compound, 10-methoxy-leonurine (1), and four known compounds (2-5) were purified by silica gel, C-18, and Sephadex LH-20 column chromatography from Leonurus japonicus. Their structures were elucidated using one-dimensional (1D)/two-dimensional (2D)-nuclear magnetic resonance (NMR), high-resolution (HR)-electrospray ionization (ESI) mass spectrometry (MS). The compounds were evaluated to determine their inhibition of the catalysis of soluble epoxide hydrolase (sEH). According to the results from in vitro analyses, compounds 1 and 2, which contain guanidine and flavonoid (3), were determined to be potential inhibitors of this enzyme. All compounds were revealed to be non-competitive inhibitors according to Lineweaver-Burk plots. Furthermore, in silico molecular docking indicated that compounds 1-3 are bound to sEH in a similar fashion and have stable binding energies, as calculated by AutoDock 4.2. Molecular dynamics determined the root-mean-square deviation (RMSD), total energy, RMS fluctuation (RMSF), hydrogen bonds, and distance of the complex according to time.
