Abstract
A phytochemical investigation led to the isolation of five undescribed compounds (1-5) from the methanol extract of the rhizomes and roots of Patrinia heterophylla. The structures and configurations of these compounds were characterized by HRESIMS, ECD, and NMR data analyses. These compounds were assayed for their anti-inflammatory potential using LPS-stimulated BV-2 cells, of which compound 4 showed strong nitric oxide (NO) inhibitory effects with an IC50 of 6.48 μM. The potential anti-inflammatory mechanism was examined utilizing Western blotting and molecular docking. Further in vivo anti-inflammatory experiments revealed that compound 4 inhibited the production of NO and reactive oxygen species in the zebrafish model.

Natural iridoids from Patrinia heterophylla showing anti-inflammatory activities in vitro and in vivo. Bioorg Chem 2020; 104:104331. [PMID: 33142407 DOI: 10.1016/j.bioorg.2020.104331] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2020] [Revised: 09/13/2020] [Accepted: 09/28/2020] [Indexed: 01/19/2023]
Abstract
Inflammation, especially chronic inflammation, has been found to be closely related to the pathology of many diseases and the discovery of bioactive natural products to inhibit NO production is one of strategies to treat inflammation. In our continuous search for bioactive natural substances as potential anti-inflammatory agents, five new compounds (1-5) were extracted and purified from Patrinia heterophylla. The NMR and MS data analysis, along with electronic circular dichroism (ECD) calculations, led to the identification of these isolates, which were new iridoids. Using cell and zebrafish models, the in vitro and in vivo anti-inflammatory effects were conducted to evaluate the potency of anti-inflammation of these compounds. The preliminary mechanism was explored using molecular docking and Western blotting experiments.

Abstract
Since the first reports of damage by Drosophila suzukii, the spotted-wing Drosophila (SWD), over a decade ago in Europe, widespread efforts have been made to understand both the ecology and the evolution of this insect pest, especially due to its phylogenetic proximity to one of the original model organisms, D. melanogaster. In addition, researchers have sought to find economically viable solutions for the monitoring and management of this agricultural pest, which has now swept across much of Europe, North America and Asia. In a new direction of study, we present an investigation of plant-based chemistry, where we search for natural compounds that are structurally similar to known olfactory cues from parasitoid wasps that in turn are well-described ovipositional avoidance cues for many Drosophila species. Here we test 11 plant species across two plant genera, Nepeta and Actinidia, and while we find iridoid compounds in both, only those odorants from Actinidia are noted to be detected by the insect antenna, and in addition, found to be behaviorally active. Moreover, the Actinidia extracts resulted in oviposition avoidance when they were added to fruit samples in the laboratory. Thus we propose the possible efficacy of these plants or their extracted chemistry as a novel means for establishing a cost-effective integrated pest management strategy towards the control of this pest fly.

Abstract
A convenient and efficient methodology for the synthesis of densely substituted pyrrole-fused isocoumarins, which employs solid-supported silica sulfuric acid (SSA) as catalyst, has been developed. When the mixture of ninhydrin adducts of acetylacetone/ethyl acetoacetate and primary amines was heated on the solid surface of SSA under solvent-free conditions, the pyrrole-fused isocoumarins were formed in good yields. This synthetic method has several advantages such as the employment of solvent-free reaction conditions without the use of any toxic reagents and metal catalysts, the ease of product isolation, the use of a recyclable catalyst, the low cost, the easy availability of the starting materials, and the excellent yields of products.

Abstract
For centuries, Patrinia heterophylla had been used in China to treat many diseases including tumor. Triterpenes has been identified as the major active constituents in Patrinia heterophylla. To elucidate the antitumor mechanism of triterpenes from Patrinia heterophylla1 (TPH), a proteomic analysis is carried out with TPH treatment in K562 cells. The total proteins extracted from TPH treated K562 cells are analyzed by two dimensional gel electrophoresis (2-DE) and compared with those untreated K562 cells. Mass spectrometry is applied to identify the differentially expressed proteins. Twenty-three differentially expressed significant proteins are discovered. Eight proteins are later identified by mass spectrometry (MALDI-TOF-MS) and Mascot software. Among them, four proteins are up-regulated (Aldolase A, Glyceraldehyde-3-phosphate dehydrogenase, Flavin reductase and Hemoglobin subunit) and four proteins were down-regulated (Heat-shock protein 90 〈Alpha〉 (HSP90-〈Alpha〉), Eukaryotic translation initiation factor 5A, Moesin, tublin) by TPH treatment in K562 cells. The identified proteins are associated with energy metabolism, oxidative stress, apoptosis, signal transduction, differential induction, and protein biosynthesis. These findings might provide valuable insights into the antitumor mechanism of TPH in K562 cells.

Abstract
The research investigated the effect of Patrinia heterophylla Bunge (Valerianaceae) polysaccharides (PHB-P1) on U14-bearing mice. The tumor weight of mice treated with PHB-P1 (30, 60 mg/kg body weight) was significantly lower than that of the control group, a decrease of serum lactate dehydrogenase (LDH) activity was observed, and the serum alkaline phosphatase (AKP) level was increased slightly. The number of apoptotic tumor cells was significantly increased in the mice by treatment of PHB-P1 (30, 60 mg/kgbw). Cell cycle analysis showed the accumulation of tumor cells in the G2/M phase and a relative decrease of the S phase. By the immunohistochemical analysis, PHB-P1 (30, 60 mg/kgbw) might up-regulate the expression of p53 and Bax, and significantly inhibited the expression of Bcl-2 in tumor tissues. In conclusion, PHB-P1 could inhibit tumor growth and induce tumor cell apoptosis.

Abstract
Background Several species from Insecta are used as remedies. Among these species, the termite Nasutitermes corniger is commonly used in traditional medicine in Northeast Brazil. The present work tests the modifying antibiotic activity of Nasutitermes corniger, a termite used in folk medicine in Northeastern region of Brazil. Methods Chlorpromazine and decocts of N. corniger were collected from two different plant species used in the traditional medicine were tested for their antimicrobial activity against strains of Escherichia coli resistant to aminoglycosides. The growth of two bacterial strains of E. coli was tested using decocts and chlorpromazine alone or associeted with aminogycosides. Results The MIC and MBC values were ≥1024 μg/ml for both strains of E. coli assayed. A significant synergism was observed between both decocts and chlorpromazine when assyed with neomycin. This synergism with neomycin indicates the involvement of an efflux system in the resistance to this aminoglycoside. Conclusion Therefore it is suggested that natural products from N. corniger could be used as a source of zoo-derived natural products with modifying antibiotic activity to aminoglycosides, being a new weapon against the bacterial resistance to antibiotics.
