Inhibition of human immunodeficiency virus type 1 replication by combination of transcription inhibitor K-12 and other antiretroviral agents in acutely and chronically infected cells. (1/274)

8-Difluoromethoxy-1-ethyl-6-fluoro-1,4-dihydro-7-[4-(2-methoxyp hen yl)-1- piperazinyl]-4-oxoquinoline-3-carboxylic acid (K-12) has recently been identified as a potent and selective inhibitor of human immunodeficiency virus type 1 (HIV-1) transcription. In this study, we examined several combinations of K-12 and other antiretroviral agents for their inhibitory effects on HIV-1 replication in acutely and chronically infected cell cultures. Combinations of K-12 and a reverse transcriptase (RT) inhibitor, either zidovudine, lamivudine, or nevirapine, synergistically inhibited HIV-1 replication in acutely infected MT-4 cells. The combination of K-12 and the protease inhibitor nelfinavir (NFV) also synergistically inhibited HIV-1, whereas the synergism of this combination was weaker than that of the combinations with the RT inhibitors. K-12 did not enhance the cytotoxicities of RT and protease inhibitors. Synergism of the combinations was also observed in acutely infected peripheral blood mononuclear cells. The combination of K-12 and cepharanthine, a nuclear factor kappa B inhibitor, synergistically inhibited HIV-1 production in tumor necrosis factor alpha-stimulated U1 cells, a promonocytic cell line chronically infected with the virus. In contrast, additive inhibition was observed for the combination of K-12 and NFV. These results indicate that the combinations of K-12 and clinically available antiretroviral agents may have potential as chemotherapeutic modalities for the treatment of HIV-1 infection.  (+info)

Effects of dauricine, quinidine, and sotalol on action potential duration of papillary muscles in vitro. (2/274)

AIM: To compare the characteristics of dauricine, sotalol, and quinidine on action potential duration (APD). METHODS: Using intracellular microelectrode method to record APD in guinea pig papillary muscles. RESULTS: Dauricine 20 mumol.L-1 prolonged action potential at 90% repolarization, the percent of APD prolongation were 22 +/- 8, 11 +/- 6, 9 +/- 5, 7 +/- 5, 6 +/- 3, 4.3 +/- 2.8, 4.5 +/- 2.8 at the cycle lengths of 200-2000 ms, dauricine became more effective in lengthening APD at short cycle lengths. The effect of dauricine on prolonging APD exhibited normal use-dependence, whereas quinidine 1 mumol.L-1 and sotalol 10 mumol.L-1 were less effective in lengthening APD at short cycle lengths. The effect of quinidine and sotalol on APD exhibited reverse use-dependence. CONCLUSSION: The effect of dauricine on APD depends on activation frequency.  (+info)

Effect of tetrandrine on proto-oncogene c-fos expression in rat cerebrum. (3/274)

AIM: To detect the effect of tetrandrine (Tet) on c-fos gene expression in cerebrum induced by lindane, a neurotoxicant which activates Ca2+ channels. METHODS: Northern and dot blotting, dual wavelength thin layer chromatography scanner, were used in this study. RESULTS: Lindane 30 mg.kg-1 given by intragastric gavage (i.g.) increased the expression of c-fos gene to 146 mm2 in rat cerebrum 1 h after treatment. Tet 1, 2, and 4 mg.kg-1 given by i.g. 30 min prior to lindane reduced c-fos gene expression in a concentration-dependent manner. Expressed genes reached only 86, 40, and 39 mm2, respectively. CONCLUSION: Tet inhibited c-fos gene expression in rat cerebrum induced by Ca2+ agonist-lindane.  (+info)

Stimulation of pregnant rat uterine contraction by the polychlorinated biphenyl (PCB) mixture aroclor 1242 may be mediated by arachidonic acid release through activation of phospholipase A2 enzymes. (4/274)

The polychlorinated biphenyl (PCB) mixture Aroclor 1242 (A1242) increases frequency of contractions of pregnant rat uteri, suggesting a possible mechanism for decreased gestational age and increased spontaneous abortion in women and animals exposed to PCBs. In the present study, we hypothesized that A1242-induced stimulation of uterine contraction is mediated by arachidonic acid released by phospholipase A2 (PLA2) enzymes. Isometric uterine contraction was measured in longitudinal uterine strips isolated from gestation day 10 rat. Pretreatment of uterine strips with the PLA2 inhibitor (E)-6-(bromomethylene)tetrahydro-3-(1-naphthalenyl)-2H-pyran-2-one (HELSS) or manoalide, or an inhibitor of the G protein of PLA2, isotetrandrine, completely prevented the increase of contractile frequency induced by 50 microM A1242. However, the phospholipase C inhibitors 2-nitro-4-carboxyphenyl-N,N-diphenylcarbamate (NCDC) and neomycin were unable to block stimulation of uterine contraction by A1242. In accordance, A1242 (100 microM) did not release inositol phosphates from myo-[3H]inositol-labeled myometrial cells, whereas myometrial cells prelabeled with [3H]arachidonic acid released arachidonic acid in a concentration- and time-dependent manner after exposure to A1242 (10-100 microM). A1242 significantly stimulated arachidonic acid release in the absence of extracellular calcium, although the release was attenuated. Analysis of the eicosanoids released by A1242 indicated that only 0.83% of released [3H]arachidonic acid was metabolized to eicosanoids and 99.07% remained as free arachidonate. Uterine contraction increased in strips exposed to exogenous arachidonic acid (1-100 microM). This study suggests that A1242 stimulates contraction in pregnant rat uterus by a mechanism involving PLA2-mediated arachidonic acid release, and that arachidonic acid, rather than eicosanoids, may mediate A1242 uterotonic action in the uterus.  (+info)

Tetrandrine inhibited chronic "inflammatory" pulmonary hypertension in rats. (5/274)

AIM: To study the effects of tetrandrine (Tet), on pulmonary hypertension. METHODS: An "inflammatory" chronic pulmonary hypertension induced by monocrotaline (Mon) in rats was used. RESULTS: Tet 50, 100, and 150 mg.kg-1.d-1 i.g. 3 wk inhibited Mon-induced increase of pulmonary artery pressure (PAP) by 23.8%, 34.9% (P < 0.05), and 42.0%, (P < 0.05); the right heart index by 2.0%, 25.0%, and 30.0% (P < 0.05) respectively compared with those from Mon group, without significant influence on the systemic artery pressure (SAP). Using histological exam by Verhoeff elastic stain and computer scanning analysis, it was found that Tet (100 mg.kg-1.d-1) for 3 wk, inhibited the increase of medial thickness and cross sectional area by 57.8% (P < 0.01) and 54.6% (P < 0.01), respectively vs Mon group. CONCLUSION: Tet ameliorated the development of pulmonary vascular and lung tissue injury induced by Mon in rats.  (+info)

Dauricine inhibited L-type calcium current in single cardiomyocyte of guinea pig. (6/274)

AIM: To study the effect of dauricine (Dau) on L-type calcium current in guinea pig ventricular myocytes. METHODS: Using whole-cell recording method to record L-type calcium current (ICa) in single ventricular cell of guinea pig. RESULTS: Dau 1, 10, and 100 mumol.L-1 markedly reduced ICa by 15.2% +/- 2.2%, 41% +/- 5%, and 82% +/- 8%, respectively. After washing out, ICa partially recovered. Dau inhibited ICa at 3 Hz and 1 Hz to a similar extent, its effect on ICa appeared to be not frequency-dependent. CONCLUSION: Dau had a calcium channel blocking effect.  (+info)

Effects of anti-rheumatic herbal medicines on cellular adhesion molecules. (7/274)

OBJECTIVE: To test the hypothesis whether herbal medicines ameliorate inflammatory diseases via the modulation of cellular adhesion molecules (CAMs). METHODS: Human neutrophils, synovial fibroblasts, and endothelial cells were incubated with different concentrations of Tripterygium Wilfordii Hook-f (TWH-f) or Tetrandrine in the presence or absence of interleukin 1 (IL1). The amount of soluble E-selectin, intercellular adhesion molecule-1 (ICAM-1) and vascular cellular adhesion molecule-1 (VCAM-1) secreted by cells were determined by ELISA. The cell surface expression of these three CAMs was detected by flow cytometry. RESULTS: TWH-f at high concentration (50 ng/ml) has a significant (p<0.05) inhibitory effect on both the secretion and the expression of the cellular adhesion molecules. However, Tetrandrine did not demonstrate the same effects. CONCLUSIONS: The cellular adhesion molecules of the endothelium and leucocytes may constitute excellent targets for the development of new anti-inflammation medicines. These results indicate that TWH could be a potential therapeutic agent in the treatment of inflammatory diseases.  (+info)

Effects of N-methyl berbamine on delayed outward potassium current in isolated rat hepatocytes. (8/274)

AIM: To study the effects of N-methyl berbamine (NMB) on the delayed outward potassium currents (Ik) in isolated rat hepatocytes. METHODS: With patch-clamp techniques and whole-cell recording method, holding potential -50 mV, command potential +30 to +140 mV, duration 900 ms. RESULTS: NMB reduced Ik in a concentration-dependent manner. When the concentrations of NMB were 20, 50, 400 nmol.L-1 and 50 mumol.L-1, the amplitude values of Ik were decreased to 3.6 +/- 0.4 (P > 0.05), 2.1 +/- 1.6 (P > 0.05), 3.7 +/- 1.6 (P < 0.05), 2.3 +/- 1.3 nA (P < 0.01) from 4.4 +/- 1.0 (n = 4), 2.5 +/- 1.8 (n = 4), 5.8 +/- 2.1 (n = 5), 4.6 +/- 1.3 (n = 6) nA of control, respectively. The inhibitory rates were 10%, 15%, 37%, and 51%, respectively. CONCLUSION: NMB was a K+ channel inhibitor.  (+info)

Tetrandrine a bis-benzylisoquinoline alkaloid, is a calcium channel blocker. It has anti-inflammatory, immunologic and antiallergenic effects. It inhibits the degranulation of mast cells. It has a quinidine-like anti-arrhythmic effect. It has been isolated from Stephania tetrandra S Moore, and other Chinese and Japanese herbs. It has vasodilatory properties and can therefore reduce blood pressure. Tetrandrine may have potential use for the treatment of liver disease and liver cancer. Tetrandrine has potential therapeutic value to prevent excess scarring/fibrosis in conjunctiva following trabeculectomy or in patients with severe conjunctival inflammation. Tetrandrine has anti-inflammatory and anti-fibrogenic actions, which make tetrandrine and related compounds potentially useful in the treatment of lung silicosis, liver cirrhosis, and rheumatoid arthritis. Tetrandrine has also been shown to inhibit entry of Ebola virus into host cells in vitro and showed therapeutic efficacy against Ebola in ...
Benzylisoquinoline is the structural backbone of many alkaloids with a wide variety of structures including papaverine, noscapine, codeine, morphine, apomorphine, berberine, protopine and tubocurarine. Many benzylisoquinoline alkaloids have been reported to show therapeutic properties and to act as novel medicines. Thus it is important to collect and compile benzylisoquinoline alkaloids in order to explore their usage in medicine. We extract information about benzylisoquinoline alkaloids from various sources like PubChem, KEGG, KNApSAcK and manual curation from literature. This information was processed and compiled in order to create a comprehensive database of benzylisoquinoline alkaloids, called BIAdb. The current version of BIAdb contains information about 846 unique benzylisoquinoline alkaloids, with multiple entries in term of source, function leads to total number of 2504 records. One of the major features of this database is that it provides data about 627 different plant species as a source of
Tetrandrine, an alkaloid isolated from the Chinese herb, Radix stephaniae tetrandrae, has been used clinically as a hypotensive agent for a long time.

The isolated rat uterus contraction induced by oxytocin and Ca+ + after high-K depolarization were markedly inhibited by tetrandrine (Tet). The depression was immediately reversed by addition of Ca++ to the bath fluid. Tet and verapamil (Ver), which shifted the cumulative dose-response curves to the right and depressed the maximal responses to CaCl2 acted as non-competitive antagonists. The oxytocin-induced Ca++-dependent contractions were depressed by 4.8 and 30 μM Tet. Tet 30 μM also inhibited the Ca++ o-dependent component of the contraction. The effect of Ver on isolated rat uterus was stronger than that of Tet. But up to 0.05 μM, it showed no effect on Ca+ +-dependent oxytocin contraction. These results indicate that Tet is an effective Ca+ +-antagonist very similar to Ver on isolated rat uteri.
Isoliensinine, a natural phenolic bisbenzyltetrahydroisoquinoline alkaloid, has received considerable attention for its potential biological effects such as antioxidant and anti-HIV activities. From the dog hepatic microsomes of isoliensinine, three new N-demethylated and O-demethylated metabolites, 2-N-desmethyl-isoliensinine (M1), 2-N-desmethylisoliensinine (M2), and 2-N-6-O-didesmethylisoliensinine (M3), were identified by high-performance liquid chromatography and data-dependent electrospray ionization tandem mass spectrometry. Possible metabolic pathways for isoliensinine have been proposed. The result should prove very helpful for evaluation of the drug-like properties of isoliensinine and other bisbenzylisoquinoline alkaloids.

Reperfusion is an essential treatment to salvage ischemia myocardium from necrosis. However, the reperfusion can also lead to additional damage. Ischemic preconditioning is a powerful way to initiate intrinsic adaptive responses protecting the heart from subsequent severe ischemia/reperfusion (I/R) injury that can be mimicked by pharmacological preconditioning. However, so far few agents are clinically available for patients with ischemia heart disease. There is a growing interest in exploring effective cardioprotective components extracted from Traditional Chinese Medicine because they have been practiced for thousands of years, providing a vast source of pharmaceutical materials. Berbamine, a kind of bisbenzylisochinoline alkaloids derived from the roots, barks and stems of Barberry, was reported to protect myocardium from ischemia/reperfusion (I/R) injury, but the underlying mechanisms are largely unknown. Here, we investigated whether berbamine confers cardioprotection via preventing calpain ...

TY - JOUR. T1 - Neferine from Nelumbo nucifera induces autophagy through the inhibition of PI3K/Akt/mTOR pathway and ROS hyper generation in A549 cells. AU - Poornima, Paramasivan. AU - Weng, Ching Feng. AU - Padma, Viswanadha Vijaya. PY - 2013/12/15. Y1 - 2013/12/15. N2 - Previously we have reported that neferine from the medicinal plant Nelumbo nucifera, inhibited cancer cell proliferation by inducing apoptosis. The present study was focused on the action mechanism of neferine in inducing autophagy in lung cancer cells. Neferine markedly inhibited A549 cell proliferation in a dose dependent manner. Acidic vesicular accumulation was observed in neferine treated cells as an indication of autophagy. Neferine could induce the conversion of LC3B-I to LC3B-II without affecting the expression levels of PI3KCIII and Beclin1. It has been observed that neferine mediated autophagy is dependent on inhibition of PI3K/Akt/mTOR signaling by neferine. Neferine treatment could also lead to the ROS ...

Curine is a bisbenzylisoquinoline alkaloid (BBA) with anti-allergic, analgesic, and anti-inflammatory properties. Previous studies have demonstrated that this alkaloid is orally active at non-toxic doses. However, the mechanisms underlying its anti-inflammatory effects remain to be elucidated. This work aimed to investigate the effects of curine on macrophage activation and neutrophil recruitment. Using a murine model of lipopolysaccharide (LPS)-induced pleurisy, we demonstrated that curine significantly inhibited the recruitment of neutrophils in association with the inhibition of cytokines tumor necrosis factor (TNF-α), interleukin (IL)-1β, IL-6, monocyte chemotactic protein (CCL2/MCP-1) as well as leukotriene B4 in the pleural lavage of mice. Curine treatment reduced cytokine levels and the expression of iNOS in in vitro cultures of macrophages stimulated with LPS. Treatment with a calcium channel blocker resulted in comparable inhibition of TNF-α and IL-1β production, as well
