Abstract
Objective: Angina pectoris (AP), affecting over 523 million people, can be alleviated by corydalis rhizome (CR), usually combined with chuanxiong rhizome (CXR), angelica dahuricae radix (ADR), or astragali radix (AR) to enhance the effect. This study aims to distinguish the different mechanisms among 3 drug pairs to treat AP. Methods: The drug pair-disease intersection targets, compound targets, protein–protein interaction (PPI), and herb-compound-target-pathway network were obtained by Cytoscape, STRING, Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses ( http://www.kegg.jp/ or http://www.genome.jp/kegg/ ). Importantly, with principal component analysis (PCA), the key point of KEGG and GO were explored and supported, while by meta-analysis, the different mechanisms of the drug pairs on AP were discovered. Results: JUN, SRC, PIK3CA, and MAPK1 as PPI core network of CR-AP, (CR-CXR)-AP, (CR-ADR)-AP, and (CR-AR)-AP. (highest confidence > 0.9). 10, 45, 35, and 21 key compounds, and 68, 123, 117, and 97 core targets were obtained from CR-AP, (CR-CXR)-AP, (CR-ADR)-AP, and (CR-AR)-AP based on more than 2-fold median value for degree and betweenness centrality, more than the median of closeness centrality. The core pathways of (CR-CXR)-AP and (CR-AR)-AP cover “fluid shear stress and atherosclerosis” and the “pathways in cancer”, while (CR-ADR)-AP was found as the “pathways in cancer” by PCA and KEGG ( P < .01). The core biological processes of (BP) (CR-CXR)-AP, (CR-ADR)-AP, and (CR-AR)-AP were all enriched in the “circulatory system process” by PCA and GO ( P < .01). Moreover, meta-analysis indicated the significant differences ( P < .05) of the 3 drug pairs. Conclusion: CR-CXR, CR-ADR, or CR-AR outperformed CR-AP in AP mitigation. Furthermore, meta-analysis revealed, CR-CXR was superior to alleviating AP by affecting “circulatory system process” and “fluid shear stress and atherosclerosis”, particularly the targets PTGS1, PTGS2, ADRB2, ADRA2C, and NOS, when compared with the drug pair of CR-ADR and the CR-AR.

In vitro functional evaluation of isolaureline, dicentrine and glaucine enantiomers at 5-HT 2 and α 1 receptors. Chem Biol Drug Des 2018; 93:132-138.

Abstract
Compounds with activity at serotonin (5-hydroxytryptamine) 5-HT2 and α1 adrenergic receptors have potential for the treatment of central nervous system disorders, drug addiction or overdose. Isolaureline, dicentrine and glaucine enantiomers were synthesized, and their in vitro functional activities at human 5-HT2 and adrenergic α1 receptor subtypes were evaluated. The enantiomers of isolaureline and dicentrine acted as antagonists at 5-HT2 and α1 receptors with (R)-isolaureline showing the greatest potency (pKb = 8.14 at the 5-HT2C receptor). Both (R)- and (S)-glaucine also antagonized α1 receptors, but they behaved very differently to the other compounds at 5-HT2 receptors: (S)-glaucine acted as a partial agonist at all three 5-HT2 receptor subtypes, whereas (R)-glaucine appeared to act as a positive allosteric modulator at the 5-HT2A receptor.

Abstract
Transcriptome resources for the medicinal plant Glaucium flavum were searched for orthologs showing identity with characterized O-methyltransferases (OMTs) involved in benzylisoquinoline alkaloid biosynthesis. Seven recombinant proteins were functionally tested using the signature alkaloid substrates for six OMTs: norlaudanosoline 6-OMT, 6-O-methyllaudanosoline 4'-OMT, reticuline 7-OMT, norreticuline 7-OMT, scoulerine 9-OMT, and tetrahydrocolumbamine OMT. A notable alkaloid in yellow horned poppy (G. flavum [GFL]) is the aporphine alkaloid glaucine, which displays C8-C6' coupling and four O-methyl groups at C6, C7, C3', and C4' as numbered on the 1-benzylisoquinoline scaffold. Three recombinant enzymes accepted 1-benzylisoquinolines with differential substrate and regiospecificity. GFLOMT2 displayed the highest amino acid sequence identity with norlaudanosoline 6-OMT, showed a preference for the 6-O-methylation of norlaudanosoline, and O-methylated the 3' and 4' hydroxyl groups of certain alkaloids. GFLOMT1 showed the highest sequence identity with 6-O-methyllaudanosoline 4'OMT and catalyzed the 6-O-methylation of norlaudanosoline, but more efficiently 4'-O-methylated the GFLOMT2 reaction product 6-O-methylnorlaudanosoline and its N-methylated derivative 6-O-methyllaudanosoline. GFLOMT1 also effectively 3'-O-methylated both reticuline and norreticuline. GFLOMT6 was most similar to scoulerine 9-OMT and efficiently catalyzed both 3'- and 7'-O-methylations of several 1-benzylisoquinolines, with a preference for N-methylated substrates. All active enzymes accepted scoulerine and tetrahydrocolumbamine. Exogenous norlaudanosoline was converted to tetra-O-methylated laudanosine using combinations of Escherichia coli producing (1) GFLOMT1, (2) either GFLOMT2 or GFLOMT6, and (3) coclaurine N-methyltransferase from Coptis japonica. Expression profiles of GFLOMT1, GFLOMT2, and GFLOMT6 in different plant organs were in agreement with the O-methylation patterns of alkaloids in G. flavum determined by high-resolution, Fourier-transform mass spectrometry.

Abstract
The aporphine alkaloids constitute the second-largest group of isoquinoline alkaloids. Nevertheless, only a relatively small number of natural aporphines and their derivatives have been studied from a pharmacological viewpoint. Here we review the pharmacological data available for these compounds as related to their dopaminergic, noradrenergic and serotonergic activities, and also some results pertaining to their effects on ion channels and enzymes.

Abstract
The action of four benzylisoquinoline alkaloids (two aporphines-glaucine and apomorphine, a benzylisoquinoline-papaverine and a bisbenzyltetrahydroisoquinoline-antioquine) on 5-HT-induced contraction in rat thoracic aorta has been examined and compared with that of the control drugs: ketanserin, nifedipine, prazosin and phentolamine. The relaxant action on 5-HT-induced contraction was contrasted with that on the contraction induced by noradrenaline and KCl. The results obtained with control drugs show that ketanserin has clear selectivity for 5-HT receptors, whereas prazosin and phentolamine have high selectivity for the alpha1-adrenoceptor and nifedipine seems to have a more potent effect on KCl-induced contraction than on that induced by 5-HT or noradrenaline. The contraction evoked by 5-HT (10 microM) was inhibited in a concentration-dependent manner by all the alkaloids. The order of potency was: papaverine = glaucine > apomorphine > antioquine. Papaverine had a non-specific relaxant action on 5-HT-, noradrenaline- and KCl-induced contraction, antioquine had a weak relaxant action on the agonist assays, and glaucine and apomorphine inhibited noradrenaline- and 5-HT-induced contraction more potently than they inhibited the K+-depolarized response. These results indicate that the aporphines assayed, S-glaucine and R-aporphine, had selective action against agonist (noradrenaline or 5-HT)-induced contraction rather than against KCl-depolarization of rat aorta. In contrast papaverine, a benzylisoquinoline alkaloid, relaxes all agents used non-selectively as could be expected from the lack of specificity that characterizes this alkaloid.

Abstract
1. In this work, the cardiovascular effects of HPS-10, a new vasodilator agent, were studied in rats. 2. In conscious normotensive rats, oral administration of HPS-10 (4-9 mg kg-1) produced a dose-related and long-lasting fall in systolic arterial blood pressure (ED30 of 5.32 mg kg-1), accompanied by an increase in heart rate (ED30 of 8.43 mg kg-1). This tachycardia was totally inhibited by pretreatment with (+/-)-propranolol (10 mg kg-1, p.o.). 3. In anaesthetized normotensive rats, HPS-10 (0.3-0.6 mg kg-1, i.v.) produced a gradual, dose-dependent and sustained decrease in systolic, diastolic and mean arterial pressure (MAP) (ED30 for MAP of 0.41 mg kg-1, i.v.), accompanied by a significant bradycardia at high doses (> 0.4 mg kg-1; ED20 of 0.61 mg kg-1, i.v.). HPS-10 (0.5 mg kg-1, i.v.) did not modify the positive chronotropic effects induced by intravenous administration of noradrenaline (NA; 5 micrograms kg-1), angiotensin II (AII; 0.2 microgram kg-1) and nicotine (200 micrograms kg-1) but markedly inhibited the hypertensive response produced by these agents. 4. In rat isolated rubbed aorta, HPS-10 (0.1-1 mM) non-competitively and with almost equal effectiveness antagonized the contractions induced by NA, AII (in normal Krebs solution) and Ca2+ (in depolarizing Ca(2+)-free high-K+ 50 mM solution). In the experiments in Ca(2+)-free medium, HPS-10 (1 mM) considerably inhibited the contractions induced by NA, AII and caffeine in rat aorta. 5. Furthermore, in the studies with radioactive Ca2+, HPS-10 (1 mM) did not modify the basal uptake of 45Ca2+ but strongly decreased the influx of 45Ca2+ induced by NA, AII and K+ in rat aortic rings. 6. In rat isolated atria, HPS-10 (1 mM) produced a positive inotropic/negative chronotropic effect. 7. HPS-10 (0.3 mM) significantly inhibited the sustained and transient Ba2+ inward current (IBa) recorded in whole-cell clamped rat aortic myocytes. 8. These results indicate that the non-selective vasorelaxant effects of HPS-10 in rat aortic rings can be attributed to transmembrane Ca(2+)-antagonist activity and an intracellular action on smooth muscle cells. The direct vasodilator action of HPS-10 observed in rat isolated aorta may be responsible for the HPS-10 hypotensive activity in anaesthetized normotensive rats.

Abstract
1. The selectivity of action of boldine and the related aporphine alkaloids, predicentrine (9-O-methylboldine) and glaucine (2,9-O-dimethylboldine) and alpha 1-adrenoceptor subtypes was studied by examining [3H]-prazosin competition binding in rat cerebral cortex. WB 4101 and benoxathian were used as selective alpha 1A-adrenoceptor antagonists. 2. In the competition experiments [3H]-prazosin (0.2 nM) binding was inhibited by WB 4101 and benoxathian. The inhibition curves displayed shallow slopes which could be subdivided into high and low affinity components (pKi = 9.92 and 8.29 for WB 4101, 9.35 and 7.94 for benoxathian). The two antagonists recognized approximately 37% of the sites with high affinity from among the total [3H]-prazosin specific binding sites. 3. Boldine, predicentrine and glaucine also competed for [3H]-prazosin (0.2 nM) binding with shallow and biphasic curves recognizing 30-40% of the sites with high affinity. Drug affinities (pKi) at the high and low affinity sites were, 8.31 and 6.50, respectively, for boldine, 8.13 and 6.39 for predicentrine, and 7.12 and 5.92 for glaucine. The relative order of selectivity for alpha 1A-adrenoceptors was boldine (70 fold alpha 1A-selective) = predicentrine (60 fold, alpha 1A-selective) > glaucine (15 fold, alpha 1A-selective). 4. Pretreatment of rat cerebral cortex membranes with chloroethylclonidine (CEC, 10 microM) for 30 min at 37 degrees C followed by thorough washing out reduced specific [3H]-prazosin binding by approximately 70%. The CEC-insensitive [3H]-prazosin binding was inhibited by boldine monophasically (Hill slope = 0.93) with a single pKi value (7.76). 5. These results suggest that whereas the aporphine structure shared by these alkaloids is responsible for their selectively of action for the alpha 1A-adrenoceptor subtype in rat cerebral cortex, defined functional groups, namely the 2-hydroxy function, induces a significant increase in alpha 1A-subtype selectivity and affinity.

Abstract
Ca2+ plays an important role in the contraction of skeletal, cardiac, and smooth muscle, as well as in a number of important processes, such as secretion and neuronal activity. In this review, I focus on the various mechanisms by which cytosolic Ca2+ concentration is regulated in vascular smooth muscle, in the resting state and during activation. Particular attention is paid to the calcium pumps of the plasmalemma and the sarcoplasmic reticulum, to the inositol 1,4,5-trisphosphate- and ryanodine-sensitive calcium channels of the sarcoplasmic reticulum, and to voltage-dependent and voltage-independent calcium channels of the plasmalemma.
