TL;DR: Twelve new and 10 known protostane triterpenoids were isolated from the rhizome of Alisma orientale and their structures were elucidated based on physical data analyses, including UV, HRESIMS, NMR experiments, and induced electronic circular dichroism.
Abstract: Twelve new and 10 known protostane triterpenoids were isolated from the rhizome of Alisma orientale. Their structures were elucidated based on physical data analyses, including UV, HRESIMS, NMR experiments ((1)H, (13)C NMR, (1)H-(1)H COSY, HSQC, HMBC, and NOESY), and induced electronic circular dichroism. New compounds 1-12 were classified as protostanes (1-10), 29-norprotostane (11), and 24-norprotostane (12) by structure analyses. Furthermore, the inhibitory effects on human carboxylesterases (hCE-1, hCE-2) of compounds 1-22 were evaluated. Compounds 2, 6, 9, and 11 showed moderate inhibitory activities and were selective toward hCE-2 enzymes, with IC50 values of 8.68, 4.72, 4.58, and 2.02 μM, respectively. The inhibition kinetics of compound 11 toward hCE-2 were established, and the Ki value was determined as 1.76 μM using a mixed inhibition model. The interaction of bioactive compound 11 with hCE-2 was shown using molecular docking.

TL;DR: It is suggested that miR-320a could play a role in modulation of inflammatory cytokins production in myasthenia gravis.
Abstract: Myasthenia gravis (MG) are T-cell dependent antibody-mediated autoimmune disorders, microRNAs are important regulators of human autoimmune disease pathogenesis. Here, we investigated the miRNAs expression profiles in MG for the first time and found that miR-320a was significantly downregulated in MG patients compared to normal healthy people. Meanwhile, pro-inflammatory cytokins in MG patients were overexpressed. Furthermore, we identified MAPK1 as a direct target of miR-320a. Downregulation of miR-320a induced the overexpression of pro-inflammatory cytokins through promoting COX-2 expression. This process was modulated by ERK/ NF-κB pathways. Taken together, our findings suggested that miR-320a could play a role in modulation of inflammatory cytokins production.

TL;DR: It is observed that BA could protect mice from infection by influenza virus A/PR/8/34 (H1N1), associated with increasing IFN-γ production, but presented no effects in IFn-γ or IFN -γ receptor deficient mice.
Abstract: Baicalin (BA) is a flavonoid compound purified from Scutellaria baicalensis Georgi and has been shown to possess a potent inhibitory activity against viruses. However, the role of BA in anti-influenza virus has not been extensively studied, and the immunological mechanism of BA in antiviral activity remains unknown. Here, we observed that BA could protect mice from infection by influenza virus A/PR/8/34 (H1N1), associated with increasing IFN-γ production, but presented no effects in IFN-γ or IFN-γ receptor deficient mice. Further study indicated that BA could inhibit A/PR/8/34 replication through IFN-γ in human PBMC. Moreover, BA can directly induce IFN-γ production in human CD4(+) and CD8(+) T cells and NK cells, and activate JAK/STAT-1 signaling pathway. Collectively, BA exhibited anti-influenza virus A (H1N1) activity in vitro and in vivo as a potent inducer of IFN-γ in major IFN-γ producing cells.

TL;DR: This study was to elucidate the pharmacokinetics of a novel alkaloid, named oleracone isolated from Portulaca oleracea L., and to examine the anti‐inflammatory ability with lipopolysaccharide (LPS) stimulated macrophages.
Abstract: Objectives
This study was to elucidate the pharmacokinetics of a novel alkaloid, 6-acetyl-2,2,5-trimethyl-2,3-dihydrocyclohepta[b]pyrrol-8(1H)-one, named oleracone isolated from Portulaca oleracea L., and to examine the anti-inflammatory ability with lipopolysaccharide (LPS) stimulated macrophages.
Methods
The novel alkaloid, oleracone, was isolated from Portulaca oleracea L., and its structure was determined by spectroscopic analysis including HRESIMS, 2D NMR spectroscopic data and single-crystal X-ray diffraction. The activity of anti-inflammation was assayed via the test with RAW 264.7 activated by LPS, and the pharmacokinetics of oleracone in rat plasma after intravenous and oral administration at dose of 2.5 mg/kg was, respectively, investigated by a rapid and sensitive ultra high-performance liquid chromatography (UHPLC) method with bergapten as internal standard.
Key findings
Oleracone was a novel alkaloid first isolated from Portulaca oleracea L. and possessed unique structure in natural products, whose anti-inflammatory effecting on nitrite oxide production and several pivotal pro-inflammatory cytokines was found at the concentration of 50 μm, and the pharmacokinetic results indicated that oleracone was rapidly distributed with Tmax of 15.7 min after oral administration and presented a higher oral absolute bioavailability to be 74.91 ± 10.7%.
Conclusions
Oleracone as novel alkaloid presented remarkably anti-inflammatory effect, which was rapid distributed in rat with high bioavailability of 74.91 ± 10.7%.
