Abstract
Phytochemical investigation on the aerial parts of Corydalis impatiens (pall.) Fisch (Papaveraceae) resulted in the identification of four previous undescribed benzylisoquinoline alkaloids, impatienines A-D (1-4), together with 14 known analogues (5-18). The structures of these compounds were elucidated by extensive spectroscopic analysis (IR, HR-ESIMS, 1D- and 2D-NMR) as well as ECD calculations. All the compounds obtained were investigated for their inhibitory effect on the growth of A549, H1299 and HepG2 cancer cells. Compounds 7 and 15 exhibited pronounced inhibition against the A549 cancer cells with IC50 values of 6.81 μM and 3.17 μM, while the positive control cisplatin was 1.83 μM. Compounds 1-3 showed moderate inhibitory on the H1299 cancer cells. Compounds 4, 10-12, and 16 showed signiffcant activity against HepG2 cancer cells with IC50 values range of 4.41-8.75 μM.

Abstract
Introduction: The aim of this study was to investigate the pharmacological mechanism of Wuwei Yuganzi San (WYS) in treating coronary heart disease (CHD) using network pharmacology and molecular docking. Methods: The main active components, related targets, and the target genes related to WYS were investigated by the databases Traditional Chinese Medicine Systems Pharmacology and related articles. Information on the target genes of CHD was acquired through the OMIM database and GeneCards database, and the NCBI Gene Expression Omnibus DataSets (GSE71226) were used to acquire target genes of CHD. A Venn diagram was used to show the common targets of WYS and CHD. The compound-target-disease network was built up by Cytoscape 3.7.2, and the protein–protein interaction (PPI) network was acquired through the STRING database. ClusterProfiler and Pathview packages in RStudio software were used to conduct gene ontology enrichment analysis and KEGG pathway enrichment analysis to reveal the underlying mechanism. Finally, AutoDock Vina software was used to assess the binding affinity of significant ingredients and hub genes. Results: Thirty-four key ingredients of WYS in CHD were screened, which related to 59 targets in CHD. According to the results of enrichment analysis, 59 items in the biological process, 15 items in the molecular function, 10 items in the cellular component, and 52 signaling pathways were associated with efficacy. These processes and pathways were essential for cell survival and were related to several crucial factors of CHD, including a disintegrin and metalloprotease 17 (ADAM17), aldo-keto reductase family 1 member C2 (AKR1C2), albumin (ALB), protein kinase B (AKT1), and alcohol dehydrogenase 1C (ADH1C). Based on the outcomes of the PPI network, we selected ADAM17, AKR1C2, ALB, AKT1, ADH1C, and putative ingredients (sennoside D_qt, quercetin, and procyanidin B-5,3'- O-gallate) to perform molecular docking validation. From the molecular docking outcomes, some vital targets of CHD (including ADAM17, AKR1C2, ALB, AKT1, and ADH1C) could be related to form a stable combination with the putative ingredients of WYS. Conclusions: The network pharmacology and molecular docking study elucidated basically the mechanism of WYS in the treatment of CHD.

Abstract
The first total synthesis of the natural product impatien A is described. This concise synthesis features an aza-Heck cyclization to construct the complex spirocyclic ring system and provides a rare example of the use of aza-Heck cyclizations in complex molecule synthesis. To enable this key cyclization of an electrophilic nitrogen atom with a tetrasubstituted alkene, we utilized high-throughput experimentation to identify a new ligand and ultimately deliver impatien A in seven steps from known compounds.

Abstract
Alkaloids are a widespread group of basic compounds in herbal medicines and have attracted great interest due to various pharmaceutical activities and desirable druggability. Their distinctive structures make chromatographic separation fairly difficult. Peak tailing, poor resolution, and inferior column-to-column reproducibility are common obstacles to overcome. In order to provide a valuable reference, the methodologies and/or strategies on liquid chromatographic separation of alkaloids in herbal medicines proposed from 2012 to 2019 are thoroughly summarized.

Preparative separation of isoquinoline alkaloids from Corydalis impatiens using a middle-pressure chromatogram isolated gel column coupled with two-dimensional liquid chromatography. J Sep Sci 2019; 42:3182-3190. [PMID: 31429171 DOI: 10.1002/jssc.201900252] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2019] [Revised: 07/24/2019] [Accepted: 08/15/2019] [Indexed: 01/24/2023]
Abstract
We established a two-dimensional strong cation exchange/reversed-phase liquid chromatography protocol to isolate and purify isoquinoline alkaloids from Corydalis impatiens. Isoquinoline alkaloids were first enriched from a C. impatiens extract in which liposoluble components were removed using a medium-pressure chromatographic tower containing middle chromatogram isolated gel. A strong cation exchange column was employed to separate and obtain 30 fractions. We chose fractions 22-29 for reversed-phase liquid chromatography purification using characteristic isoquinoline alkaloid ultraviolet absorption spectra. Several isoquinoline alkaloid fractions (22-29) were further separated, and those of low resolution were isolated via two-dimensional liquid chromatography in the orthogonal plane. A total of eight novel isoquinoline alkaloids with characteristic ultraviolet spectra were obtained from C. impatiens. We thus demonstrate the benefits of off-line two-dimensional strong cation exchange/reversed-phase liquid chromatography to isolate isoquinoline alkaloids from C. impatiens.

Abstract
Arecoline can be used to treat diseases including glaucoma and tapeworm infection, however, long-term administration can cause severe adverse effects, including oral submucosal fibrosis, oral cancer, hepatic injury and liver cancer. Autophagy serves a role in these injuries. The present study established a mouse model of arecoline-induced hepatic injury and investigated the role of autophagy-associated proteins in this injury. The results indicated that the expression levels of the autophagy marker protein microtubule associated protein 1 light chain 3 B (MAP1LC3B) and autophagy-promoting protein beclin 1 were elevated in the injured hepatic cells, while the expression levels of a well-known negative regulator of autophagy, mammalian target of rapamycin (mTOR), were reduced. Following treatment of the hepatic injury with glutathione, the liver function improved and liver damage was reduced effectively. Compared with the control group, the expression levels of both MAP1LC3B and beclin 1 were significantly upregulated in the glutathione-treated mice, but the expression of mTOR was significantly downregulated. It may be concluded that in the process of protecting against arecoline-induced hepatic injury, glutathione cooperates with mTOR and beclin 1 to accelerate autophagy, maintaining stable cell morphology and cellular functions.

Abstract
YiGan San (YGS) has long been used in traditional Japanese and Chinese folk medicine and serves as a potent and novel therapeutic agent to treat Alzheimer's disease. In the present study, a rapid and sensitive method based on HPLC coupled with diode-array detection and quadrupole TOF MS (Q-TOF-MS) was designed to reveal the chemical constituents of YGS. Thirty-six compounds were identified and assigned in YGS, including 14 alkaloids, nine γ-lactones, six flavonoids, three triterpenoid saponinares, two small molecular organic acids, and two other types of compounds. In addition, the accurate fragment weight and MS/MS fragmentation reactions of a subtype indole alkaloid in Uncariae ramulus cum uncis were summarized for the first time to realize rapid identification without reference substances. For the first time, 11 major constituents were comprehensively quantified with a HPLC coupled with triple-quadrupole MS method. A three-section switch was used to realize such multicomponent identification. The contents of saikosaponin B2 and isoliquiritin, which produce anti-inflammatory and antidepressant-like effects, were extremely different, up to 700 times, in two sources of YGS. The developed qualitative and quantitative method was proved to be precise, accurate, and reproducible.
