Blocking angiotensin II ameliorates proteinuria and glomerular lesions in progressive mesangioproliferative glomerulonephritis. (1/3157)

BACKGROUND: The renin-angiotensin system is thought to be involved in the progression of glomerulonephritis (GN) into end-stage renal failure (ESRF) because of the observed renoprotective effects of angiotensin-converting enzyme inhibitors (ACEIs). However, ACEIs have pharmacological effects other than ACE inhibition that may help lower blood pressure and preserve glomerular structure. We previously reported a new animal model of progressive glomerulosclerosis induced by a single intravenous injection of an anti-Thy-1 monoclonal antibody, MoAb 1-22-3, in uninephrectomized rats. Using this new model of progressive GN, we examined the hypothesis that ACEIs prevent the progression to ESRF by modulating the effects of angiotensin II (Ang II) on the production of transforming growth factor-beta (TGF-beta) and extracellular matrix components. METHODS: We studied the effect of an ACEI (cilazapril) and an Ang II type 1 receptor antagonist (candesartan) on the clinical features and morphological lesions in the rat model previously reported. After 10 weeks of treatment with equihypotensive doses of cilazapril, cilazapril plus Hoe 140 (a bradykinin receptor B2 antagonist), candesartan, and hydralazine, we examined systolic blood pressure, urinary protein excretion, creatinine clearance, the glomerulosclerosis index, and the tubulointerstitial lesion index. We performed a semiquantitative evaluation of glomerular immunostaining for TGF-beta and collagen types I and III by immunofluorescence study and of these cortical mRNA levels by Northern blot analysis. RESULTS: Untreated rats developed massive proteinuria, renal dysfunction, and severe glomerular and tubulointerstitial injury, whereas uninephrectomized control rats did not. There was a significant increase in the levels of glomerular protein and cortical mRNA for TGF-beta and collagen types I and III in untreated rats. Cilazapril and candesartan prevented massive proteinuria, increased creatinine clearance, and ameliorated glomerular and tubulointerstitial injury. These drugs also reduced levels of glomerular protein and cortical mRNA for TGF-beta and collagen types I and III. Hoe 140 failed to blunt the renoprotective effect of cilazapril. Hydralazine did not exhibit a renoprotective effect. CONCLUSION: These results indicate that ACEIs prevent the progression to ESRF by modulating the effects of Ang II via Ang II type 1 receptor on the production of TGF-beta and collagen types I and III, as well as on intrarenal hemodynamics, but not by either increasing bradykinin activity or reducing blood pressure in this rat model of mesangial proliferative GN.  (+info)

Mibefradil (Ro 40-5967) inhibits several Ca2+ and K+ currents in human fusion-competent myoblasts. (2/3157)

1. The effect of mibefradil (Ro 40-5967), an inhibitor of T-type Ca2+ current (I(Ca)(T)), on myoblast fusion and on several voltage-gated currents expressed by fusion-competent myoblasts was examined. 2. At a concentration of 5 microM, mibefradil decreases myoblast fusion by 57%. At this concentration, the peak amplitudes of I(Ca)(T) and L-type Ca2+ current (I(Ca)(L)) measured in fusion-competent myoblasts are reduced by 95 and 80%, respectively. The IC50 of mibefradil for I(Ca)(T) and I(Ca)(L) are 0.7 and 2 microM, respectively. 3. At low concentrations, mibefradil increased the amplitude of I(Ca)(L) with respect to control. 4. Mibefradil blocked three voltage-gated K+ currents expressed by human fusion-competent myoblasts: a delayed rectifier K+ current, an ether-a-go-go K+ current, and an inward rectifier K+ current, with a respective IC50 of 0.3, 0.7 and 5.6 microM. 5. It is concluded that mibefradil can interfere with myoblast fusion, a mechanism fundamental to muscle growth and repair, and that the interpretation of the effect of mibefradil in a given system should take into account the action of this drug on ionic currents other than Ca2+ currents.  (+info)

Binding of Cob(II)alamin to the adenosylcobalamin-dependent ribonucleotide reductase from Lactobacillus leichmannii. Identification of dimethylbenzimidazole as the axial ligand. (3/3157)

The ribonucleoside triphosphate reductase (RTPR) from Lactobacillus leichmannii catalyzes the reduction of nucleoside 5'-triphosphates to 2'-deoxynucleoside 5'-triphosphates and uses coenzyme B12, adenosylcobalamin (AdoCbl), as a cofactor. Use of a mechanism-based inhibitor, 2'-deoxy-2'-methylenecytidine 5'-triphosphate, and isotopically labeled RTPR and AdoCbl in conjunction with EPR spectroscopy has allowed identification of the lower axial ligand of cob(II)alamin when bound to RTPR. In common with the AdoCbl-dependent enzymes catalyzing irreversible heteroatom migrations and in contrast to the enzymes catalyzing reversible carbon skeleton rearrangements, the dimethylbenzimidazole moiety of the cofactor is not displaced by a protein histidine upon binding to RTPR.  (+info)

Resetting of exaggerated tubuloglomerular feedback activity in acutely volume-expanded young SHR. (4/3157)

One purpose of the present study was to evaluate the ability of 7-wk-old spontaneously hypertensive rats (SHR) to reset tubuloglomerular feedback (TGF) activity in response to acute volume expansion (VE). Second, we evaluated the contribution of ANG II, via its action on AT1 receptors, to TGF control of glomerular function during VE. TGF was assessed by micropuncture methods and proximal tubular stop-flow pressure (SFP) determinations in SHR, Wistar-Kyoto rats (WKY), and Sprague-Dawley rats (SD). During euvolemia SHR exhibited enhanced TGF activity. In the same animals acute VE was achieved by infusion of saline (5 ml. h-1. 100 g body wt-1). VE led to resetting of TGF in all three strains. Maximal SFP responses, elicited by a 30-40 nl/min loop of Henle perfusion rate, decreased from 19 to 12 mmHg in SHR and, on average, from 11 to 5 mmHg in WKY and SD (P < 0.001). Tubular flow rate producing a half-maximal response (turning point) shifted to higher flow rates during VE, from 12 to 14 nl/min in SHR and from 15 to 19 nl/min in WKY. Administration of the AT1 receptor blocker candesartan (0.05 mg/kg iv) during sustained VE decreased TGF-mediated reductions in SFP in SHR and slightly increased the turning point in WKY. Nevertheless, other parameters of TGF activity were unaffected by AT1 receptor blockade. In conclusion, young SHR possess the ability to reset TGF activity in response to VE to a degree similar to compensatory adjustments in WKY. However, TGF remains enhanced in SHR during VE. ANG II and its action on AT1 receptors are in part responsible for the exaggerated SFP responses in young SHR during VE.  (+info)

Effect of 5-HT4 receptor stimulation on the pacemaker current I(f) in human isolated atrial myocytes. (5/3157)

OBJECTIVE: 5-HT4 receptors are present in human atrial cells and their stimulation has been implicated in the genesis of atrial arrhythmias including atrial fibrillation. An I(f)-like current has been recorded in human atrial myocytes, where it is modulated by beta-adrenergic stimulation. In the present study, we investigated the effect of serotonin (5-hydroxytryptamine, 5-HT) on I(f) electrophysiological properties, in order to get an insight into the possible contribution of I(f) to the arrhythmogenic action of 5-HT in human atria. METHODS: Human atrial myocytes were isolated by enzymatic digestion from samples of atrial appendage of patients undergoing coeffective cardiac surgery. Patch-clamped cells were superfused with a modified Tyrode's solution in order to amplify I(f) and reduce overlapping currents. RESULTS AND CONCLUSIONS: A time-dependent, cesium-sensitive increasing inward current, that we had previously described having the electrophysiological properties of the pacemaker current I(f), was elicited by negative steps (-60 to -130 mV) from a holding potential of -40 mV. Boltzmann fit of control activation curves gave a midpoint (V1/2) of -88.9 +/- 2.6 mV (n = 14). 5-HT (1 microM) consistently caused a positive shift of V1/2 of 11.0 +/- 2.0 mV (n = 8, p < 0.001) of the activation curve toward less negative potentials, thus increasing the amount of current activated by clamp steps near the physiological maximum diastolic potential of these cells. The effect was dose-dependent, the EC50 being 0.14 microM. Maximum current amplitude was not changed by 5-HT. 5-HT did not increase I(f) amplitude when the current was maximally activated by cAMP perfused into the cell. The selective 5-HT4 antagonists, DAU 6285 (10 microM) and GR 125487 (1 microM), completely prevented the effect of 5-HT on I(f). The shift of V1/2 caused by 1 microM 5-HT in the presence of DAU 6285 or GR 125487 was 0.3 +/- 1 mV (n = 6) and 1.0 +/- 0.6 mV (n = 5), respectively (p < 0.01 versus 5-HT alone). The effect of 5-HT4 receptor blockade was specific, since neither DAU 6285 nor GR 125487 prevented the effect of 1 microM isoprenaline on I(f). Thus, 5-HT4 stimulation increases I(f) in human atrial myocytes; this effect may contribute to the arrhythmogenic action of 5-HT in human atrium.  (+info)

Differential effects of pinacidil, cromakalim, and NS 1619 on electrically evoked contractions in rat vas deferens. (6/3157)

AIM: To compare the inhibitory action of electrically evoked contractions of rat epididymal vas deferens by pinacidil (Pin), cromakalim (Cro), and NS 1619. METHODS: Monophasic contractions were evoked by electric field stimulation in rat isolated epididymal half of vas deferens. RESULTS: Newly developed ATP-sensitive K+ channel openers, Pin and Cro, concentration-dependently reduced the electrically evoked (0.3 Hz, 1 ms pulse duration, 60 V) contractions and glibenclamide but not charybdotoxin antagonized the inhibitory effects of both agents. Pin shifted the concentration-response curve for norepinephrine to the right with reducing the magnitude of the maximum contraction in a glibenclamide-sensitive fashion. The large-conductance Ca(2+)-activated K+ channel opener, NS 1619, inhibited the electrically evoked contractions in a concentration-dependent manner. Charybdotoxin (100 nmol.L-1) partially reduced the effect of NS 1619 but glibenclamide (10 mumol.L-1) showed no effect. None of these 3 agents affected the basal tension. CONCLUSION: Both ATP-sensitive and Ca(2+)-activated K+ channels presented in vas deferens smooth muscles involved in regulation of muscle contractility.  (+info)

Development of nuclear transfer and parthenogenetic rabbit embryos activated with inositol 1,4,5-trisphosphate. (7/3157)

The present study was carried out to evaluate the effects of different activation protocols, enucleation methods, and culture media on the development of parthenogenetic and nuclear transfer (NT) rabbit embryos. Electroporation of 25 mM inositol 1,4, 5-trisphosphate (IP3) in calcium- and magnesium-free PBS immediately induced a single intracellular calcium transient in 6 out of 14 metaphase II-stage rabbit oocytes evaluated during a 10-min recording period. The percentage of oocytes treated with IP3 followed by 6-dimethylaminopurine (IP3 + DMAP) that cleaved (83.9%) and reached the blastocyst stage (50%) was significantly higher (p < 0.05) than those activated with multiple pulses (61.6% and 30.1%, respectively) or treated with ionomycin + DMAP (52.9% and 5.7%, respectively). Development of IP3 + DMAP-activated rabbit oocytes and in vivo-fertilized zygotes in different culture media was studied. Development of activated oocytes to the blastocyst stage in Earle's balanced salt solution (EBSS) supplemented with MEM nonessential amino acids, basal medium Eagle amino acids, 1 mM L-glutamine, 0.4 mM sodium pyruvate, and 10% fetal bovine serum (FBS) (EBSS-complete) (40.6%) was significantly higher (p < 0.05) than those that developed in either Dulbecco's Modified Eagle's medium (DMEM)/RPMI + 10% FBS (15.5%) or CR1aa + 10% FBS (4%) medium. In addition, 100% of in vivo-fertilized rabbit zygotes developed to the blastocyst stage in EBSS-complete. A third set of experiments was carried out to study the efficiency of blind versus stained (Hoechst 33342) enucleation of oocytes. Twenty-nine of 48 blind enucleated and IP3 + DMAP-activated oocytes cleaved (60.4%), and 15 (31.2%) subsequently reached the blastocyst stage, whereas 9 of 52 oocytes enucleated using epifluorescence (17.3%) cleaved, and none of these reached the blastocyst stage. When the above parameters that yielded the highest blastocysts were combined in an NT experiment using adult rabbit fibroblast nuclei, 72.2% (39 of 54) of the fused nuclear transplant embryos cleaved and 29.6% (16 of 54) reached the blastocyst stage.  (+info)

Serial changes in sarcoplasmic reticulum gene expression in volume-overloaded cardiac hypertrophy in the rat: effect of an angiotensin II receptor antagonist. (8/3157)

This study was designed to clarify whether gene expression in the cardiac sarcoplasmic reticulum [sarcoplasmic reticulum Ca2+-ATPase (SERCA), phospholamban, ryanodine receptor and calsequestrin] changes in accordance with left ventricular functional alterations in the volume-overloaded heart. Further, the effect of the angiotensin II type 1 receptor antagonist, TCV-116, on the expression of these genes was also evaluated. Left ventricular fractional shortening was significantly increased at 7 days, had returned to control levels at 21 days, and had significantly decreased at 35 days after the shunt operation, compared with sham-operated rats. The level of SERCA mRNA was significantly decreased at both 21 days and 35 days after the shunt operation. The levels of ryanodine receptor and phospholamban mRNAs were significantly decreased at 35 days in shunt-operated rats. The decrease in the SERCA mRNA level preceded the development of cardiac dysfunction. The levels of SERCA and ryanodine receptor mRNAs were correlated positively with left ventricular fractional shortening (r=0.73, P<0.0001 and r=0.61, P<0.01 respectively). Attenuation of the decrease in left ventricular fractional shortening occurred on treatment with TCV-116. After the treatment with TCV-116, the levels of SERCA and phospholamban mRNAs were restored to the respective values in sham-operated rats. Ryanodine receptor mRNA levels remained unchanged after treatment with TCV-116. These results indicate that the down-regulation of SERCA and ryanodine receptor mRNA levels may be related to cardiac dysfunction in the volume-overloaded heart. In addition, treatment with an angiotensin II receptor antagonist may restore the altered sarcoplasmic reticulum mRNA levels to control levels, and this may result in attenuation of the functional impairment in the volume-overloaded heart.  (+info)

A water-assisted tandem N-alkylation-reduction-condensation process has been devised as a new synthetic route for the one-pot synthesis of N-arylmethyl-2-substituted benzimidazoles. Water plays the crucial and indispensable role through hydrogen bond mediated electrophile-nucleophile dual activation in pro
Candesartan (rINN) /ˌkændɪˈsɑːrtən/ is an angiotensin II receptor antagonist used mainly for the treatment of hypertension. The prodrug candesartan cilexetil is marketed by AstraZeneca and Takeda Pharmaceuticals, commonly under the trade names Diceran,Blopress, Atacand, Amias, and Ratacand. It is available in generic form. As with other angiotensin II receptor antagonists, candesartan is indicated for the treatment of hypertension. Results from the CHARM study (early 2000s) demonstrated the morbidity and mortality reduction benefits of candesartan therapy in congestive heart failure. Thus, while ACE inhibitors are still considered first-line therapy in heart failure, candesartan can be used in combination with an ACE to achieve improved mortality and morbidity vs. an ACE alone and additionally is an alternative in patients intolerant of ACE inhibitor therapy. In a four-year randomized controlled trial, candesartan was compared to placebo to see whether it could prevent or postpone the ...
The majority of patients in the trial had stable coronary artery disease (65%) while 35% had an acute coronary syndrome. Approximately one-third had a prior MI. There was no difference in the primary endpoint of major cardiovascular events between groups, which occurred in 25.8% of the candesartan group and 28.1% of the standard therapy group (relative risk [RR] 0.89, 95% CI 0.76-1.06, p = 0.19). Among the components of the composite, there were no significant differences, but the point estimate for CV death or MI fell in favor of standard therapy (p = 0.53) while the point estimates for the remaining endpoints fell in favor of candesartan. There was also no difference in the secondary endpoint of revascularization (25.0% for candesartan vs. 26.4% for standard therapy, p = 0.41). New onset diabetes, however, was reduced in the candesartan group (1.1% vs. 2.9%, p = 0.027). Drug-related adverse events were lower in the candesartan group (p = 0.027), as was study drug discontinuation (p < ...
A recent double-blind study of the treatment of hypertensive patients whose blood pressure remained above target on two-drug combinations, showed that a strategy of adding candesartan cilexetil (Atacand®) or of switching to candesartan and hydrochlorothiazide produced further reductions in blood pressure while maintaining tolerability. In addition, the results showed a trend in favour of the three-drug, standard-dose approach, compared to the two-drug, high-dose approach.

RATIONALE: A novel benzimidazole compound ZLN005 was previously identified as a transcriptional activator of peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) in certain metabolic tissues. Upregulation of PGC-1α by ZLN005 has been shown to have beneficial effect in a diabetic mouse model and in a coronary artery disease model in vitro. ZLN005 could also have therapeutic potential in neurodegenerative diseases involving down-regulation of PGC-1α. Given the phenotypic efficacy of ZLN005 in several animal models of human disease, its metabolic profile was investigated to guide the development of novel therapeutics using ZLN005 as the lead compound ...

There is a strong association between chronic inflammatory conditions in a particular organ and the incidence of cancer specific to that organ. The longer the inflammation persists, the higher is the risk of associated carcinogenesis. Our interest is to synthesis new, potent and safer anticancer agents. The functionalized tetrahydropyridine (THP) ring systems are widely found in biologically active natural products and pharmaceuticals. The pharmacological activities of the THP derivatives depended greatly on the position and nature of the substitutions on the THP ring structure. 2-Substituted benzimidazole derivatives have been found to possess anti-inflammatory, antihistaminic, antimicrobial, anticancer, and cycloxygenase inhibiting activities. It is believed that synthesizing new compounds that contain both the pharmacophores of THP and benzimidazole could have the potential of becoming effective anticancer agents.. 6-Methyl-2-(pyridin-4-yl)-1H-benzo[d]imidazole was obtained by the reaction of ...

Volume depletion due to persistent glucosuria-induced osmotic diuresis is a significant problem in uncontrolled diabetes mellitus (DM). Angiotensin II receptor blockers (ARBs), such as candesartan, slow the progression of chronic kidney disease in patients with DM. However, mice with genetic knockout of components of the renin-angiotensin system have urine concentrating defects, suggesting that ARBs may exacerbate the volume depletion. Therefore, the effect of candesartan on UT-A1, UT-A3, NKCC2, and aquaporin-2 (AQP2) protein abundances was determined in control and 3-wk DM rats. Aldosterone levels in control rats (0.36 ± 0.06 nM) and candesartan-treated rats (0.34 ± 0.14 nM) were the same. DM rats had higher aldosterone levels (1.48 ± 0.37 nM) that were decreased by candesartan (0.97 ± 0.26 nM). Western analysis showed that UT-A1 expression was increased in DM rats compared with controls in inner medullary (IM) tip (158 ± 13%) and base (120 ± 25%). UT-A3 abundance was increased in IM tip ...

INDICATIONS. Albenza is a member of the benzimidazole compounds used as a drug indicated for the treatment of a variety of worm infestations. It is a broad spectrum anthelmintic, effective against: roundworms, tapeworms, and flukes of domestic animals and humans.. As a vermicidal, albendazole causes degenerative alterations in the tegument and intestinal cells of the worm by binding to the colchicine-sensitive site of tubulin, thus inhibiting its polymerization or assembly into microtubules. The loss of the cytoplasmic microtubules leads to impaired uptake of glucose by the larval and adult stages of the susceptible parasites, and depletes their glycogen stores. Degenerative changes in the endoplasmic reticulum, the mitochondria of the germinal layer, and the subsequent release of lysosomes result in decreased production of adenosine triphosphate (ATP), which is the energy required for the survival of the helminth. Due to diminished energy production, the parasite is immobilized and eventually ...

The purpose of the current study is to examine the relative roles of the extracellular signal‐regulated kinases 1, 2, and 5 (ERK1/2 and ERK5) and novel benzimidazole inhibitor compounds in cellular proliferation in breast tumors with aging. Breast cancer risk progressively increases with age, in part due to an accumulation of genetic mutations that occur during cellular division and/or exposure to environmental toxins. It has been estimated that over the next thirty years the number of Americans older than 65 years of age will double. With this increase in the aged population, the incidence of breast cancer will rise; therefore, it is important to examine the underlying mechanisms involved in breast tumor proliferation with aging. It has been well established that activation of the mitogen‐activated protein kinase (MAPK) ERK1/2 leads to increased cellular proliferation and differentiation in cancer cells. Many of these studies rely on pharmacological inhibitors that were thought to be ...

In this study, we investigated the anticancer effects of a new benzimidazole derivative, 1-benzyl-2-phenyl -benzimidazole (BPB), in human chondrosarcoma cells. BPB-mediated apoptosis was assessed by the MTT assay and flow cytometry analysis. The in vivo efficacy was examined in a JJ012 xenograft model. Here we found that BPB induced apoptosis in human chondrosarcoma cell lines (JJ012 and SW1353) but not in primary chondrocytes. BPB induced upregulation of Bax, Bad and Bak, downregulation of Bcl-2, Bid and Bcl-XL and dysfunction of mitochondria in chondrosarcoma. In addition, BPB also promoted cytosolic releases AIF and Endo G. Furthermore, it triggered extrinsic death receptor-dependent pathway, which was characterized by activating Fas, FADD and caspase-8. Most importantly, animal studies revealed a dramatic 40% reduction in tumor volume after 21 days of treatment. Thus, BPB may be a novel anticancer agent for the treatment of chondrosarcoma.

No carcinogenicity studies have been conducted with the combination of candesartan cilexetil and hydrochlorothiazide. There was no evidence of carcinogenicity when candesartan cilexetil was orally administered to mice and rats for up to 104 weeks at doses up to 100 and 1,000 mg/kg/day, respectively. Rats received the drug by gavage whereas mice received the drug by dietary administration. These (maximally-tolerated) doses of candesartan cilexetil provided systemic exposures to candesartan (AUCs) that were, in mice, approximately 7 times and, in rats, more than 70 times the exposure in man at the maximum recommended daily human dose (32 mg). Two-year feeding studies in mice and rats conducted under the auspices of the National Toxicology Program (NTP) uncovered no evidence of a carcinogenic potential of hydrochlorothiazide in female mice (at doses of up to approximately 600 mg/kg/day) or in male and female rats (at doses of up to approximately 100 mg/kg/day). The NTP, however, found equivocal ...
A16 Benzimidazoles are important compounds because of their antibacterial, antifungal, antimicrobial, antiprotozoal and antihelmintic activities. Some benzimidazole derivatives also interfere with the reactions of DNA topoisomerases, the enzymes functioning at almost all stages of the cell cycle. In this study, nine 1H-benzimidazole derivatives with substituents at positions 2- and 5- were synthesized and the structure of the compounds were elucidated by instrumental methods. The characterized compounds were screened to identify if they interfere with mammalian type I DNA topoisomerase activity via in vitro supercoil relaxation assays. Selected compounds were subjected to cytostatic assays using HeLa (cervix adenocarcinoma), MCF7 (breast adenocarcinoma) and A431 (skin epidermoid carcinoma) cells. Our results showed that 5-chloro-2-(2-hydroxyphenyl)-1H-benzimidazole exerted the most profound topoisomerase I inhibition and cytotoxicity. ...
With an aim to identify the structural requirements for selective AT1 angiotensin antagonistic activity, a quantitative structure activity relationship (QSAR) analysis was carried out on a series of 6-substituted benzimidazole derivatives. The QSAR expressions were generated using 28 compounds and the predictive ability of the resulting model was evaluated against a test set of 12 compounds. The internal (cross validated squared correlation coefficient) and external consistency (predictive correlation coefficient) of the QSAR model was 0.78 and 0.40 respectively. In the present work QSAR analysis reveals that geometrical, structural, and shape descriptors govern the angiotensin II AT1 antagonistic activity.

Fresh isolations of Ostertagia spp. from sheep in a continuing field experiment confirmed a substantially lower level of benzimidazole resistance in the progeny of worms which had survived repeated doses of levamisole than in the progeny of those not exposed to any anthelmintic for 7 months. These resistance levels had remained unchanged for 4 months. Five generations of laboratory selection with levamisole had no effect on the level of benzimidazole resistance in a highly resistant line of the parasite isolated from the same field experiment. The effect of levamisole treatment in the field experiment was probably not due to a negative correlation between benzimidazole and levamisole resistance in the parasitic stages, but could be explained by the population dynamics of the parasite. It is postulated that levamisole treatment resulted in the replacement of a highly benzimidazole resistant parasitic population by one reflecting a lower frequency of resistant individuals in the infective larval ...

Background: Microalbuminuria in diabetes is strongly predictive of nephropathy, end-stage renal disease, and premature cardiovascular morbidity and mortality. Effective preventive therapies are therefore a clinical priority.. Objective: To determine whether the angiotensin-receptor blocker candesartan compared with placebo affects microalbuminuria incidence or rate of change in albuminuria in type 1 and type 2 diabetes.. Design: 3 randomized trials of the DIRECT (Diabetic Retinopathy Candesartan Trials) Program.. Setting: 309 secondary care centers.. Patients: 3326 and 1905 patients with type 1 and type 2 diabetes, respectively. Most were normotensive, and all had normoalbuminuria (median urinary albumin excretion rate, 5.0 µg/min).. Intervention: Candesartan, 16 mg/d increasing to 32 mg/d, versus placebo. Assignment was done centrally using an interactive voice-response system. Patients, caregivers, and researchers were blinded to treatment assignment. During a median follow-up of 4.7 years, ...
In this study, we evaluated and compared the effects of olmesartan and candesartan monotherapy on lipid metabolism and renal function. We found that the reduction of serum TG level in olmesartan users was significantly greater than that in candesartan users, although there were no significant differences in the mean values of all test results between baseline and during the exposure period in both users. These results suggest minimal effects of olmesartan monotherapy on lipid metabolism and renal function, the same as with candesartan monotherapy. The results also suggest that olmesartan monotherapy may have a more beneficial effect on TG metabolism than candesartan monotherapy. Stratified analysis showed the same outcome in patients with diabetes or hyperlipidemia as that in the overall population, with a significant reduction of serum TG level in olmesartan users in comparison with candesartan users. These results suggest a more beneficial effect of olmesartan monotherapy on TG metabolism than ...

Anthelmintic resistance in nematodes can be a problem in sheep, goats, horses, cattle and pigs. The most widespread resistance problems occur to benzimidazol anthelmintics in nematodes of sheep, goats and horses. Reports of this type of resistance have emanated from Australia. Africa, Europe North and South America; wherever animals are regularly treated with anthelmintics and investigation have been made. Beveridge et al. (1990), Eady et al. (1998), Rolfe (1993) and Waller et al.( !986) found a high level of benzimidazole resistance in gastro-intestinal nematodes in sheep in Australia. In Europe an increasing incidence of anthelmintic resistance in sheep were reported in Great Britain (Coles 1997, Hunt et al. 1992), in France (Guerin 1996) and in Denmark (Maingi et al. 1997). In USA benzimidazole resistance of gastro-intestinal nematodes in sheep were found in North Carolina (Uhlinger et al. 1992) and in eastern region (Lyons et al. 1992). Benzimidazole resistance in cyathostomes in horses has ...

The efficacy and tolerability of two candesartan treatment regimens were evaluated in 578 severely hypertensive patients already receiving a diuretic plus an angiotensin-converting enzyme (ACE) inhibitor, a calcium channel blocker (CCB) or a beta blocker. Existing treatments were standardised during a two-week run-in period. Patients with uncontrolled blood pressure (diastolic blood pressure [DBP] > 90 mmHg) were randomly switched to a regimen comprising candesartan 16 mg plus hydrochlorothiazide (HCT) 12.5 mg once daily for four weeks (switch regimen, n=291), or had candesartan 8 mg once daily added to their existing treatment (add-on regimen, n=287). After four weeks treatment, mean sitting DBP was reduced from baseline by 11.2 mmHg (SD 11.2) and 13.9 mmHg (SD 11.5) in the switch and add-on treatment groups, respectively. Mean sitting SBP was decreased by 15.3 mmHg (SD 18.7) and 20.7 mmHg (SD 20.3), respectively. During an additional four weeks treatment, switch non-responders had their ...

Abstract:. Candesartan is potent antihypertensive drug of class angiotensin II receptor antagonist. But it exhibits poor water solubility and extensive first pass metabolism. Present research deals with development of candesartan buccal film. Optimisation of buccal film was done by design expert. Optimised concentration range selected for development of trial batches of candesaratanbuccal films. Mucoadhesivebuccal films of candesartan were prepared by solvent casting technique using chitosan, HPMC, gelatin and EDTA as permeation enhancer. Prepared buccal films evaluated for various pharmaceutical parameters, stability studies, in-vitro and ex-vivo evaluation parameters performed. In-vitroangiotensin II receptor antagonist studies were also performed. Results showed improved bioavaibility of candesartan through buccal films.. ...

INDICATIONS. Albenza is a member of the benzimidazole compounds used as a drug indicated for the treatment of a variety of worm infestations. It is a broad spectrum anthelmintic, effective against: roundworms, tapeworms, and flukes of domestic animals and humans.. As a vermicidal, albendazole causes degenerative alterations in the tegument and intestinal cells of the worm by binding to the colchicine-sensitive site of tubulin, thus inhibiting its polymerization or assembly into microtubules. The loss of the cytoplasmic microtubules leads to impaired uptake of glucose by the larval and adult stages of the susceptible parasites, and depletes their glycogen stores. Degenerative changes in the endoplasmic reticulum, the mitochondria of the germinal layer, and the subsequent release of lysosomes result in decreased production of adenosine triphosphate (ATP), which is the energy required for the survival of the helminth. Due to diminished energy production, the parasite is immobilized and eventually ...
During candesartan infusion, the AERP was no longer shortened by rapid pacing (Figure 1A⇑). The AERP at baseline (131±5, 142±9, and 148±10 ms at BCLs of 200, 300, and 400 ms, respectively) was not significantly different from the corresponding AERP after the termination of rapid pacing (136±9, 147±12, and 153±13 ms at BCLs of 200, 300, and 400 ms respectively) (Table 1⇑). The percent change in AERP in the candesartan group was significantly less than that in the saline group (+4.1±7.7% versus −11.3±8.9%, +3.7±8.3% versus −10.6±11.0% at BCLs of 300 and 400 ms, respectively, P,0.01) (Figure 2⇑).. In the captopril-treated group, the time course of electrical remodeling was similar to that in the candesartan-treated group and the AERP was not shortened during rapid pacing (baseline versus after 180 minutes of pacing: from 140±15 to 137±11, from 153±15 to 153±14, and from 166±22 to 174±20 ms at BCLs of 200, 300, and 400 ms, respectively) (Table 1⇑, Figure 1A⇑).

RE-LY is the largest randomized experience reporting outcomes after interruption of anticoagulant therapy.1 There was no excess of bleeding in patients taking dabigatran, including those having major or urgent surgery.1 David and colleagues correctly state that the majority of procedures performed during the RE-LY trial were minor. Nonetheless, our analysis included 1482 major procedures that had a 6% to 8% rate of major bleeding,1 which was numerically lower among dabigatran-treated patients.1. Hjemdahl et al opine that the high rate of major bleeding in RE-LY patients assigned to dabigatran 150 mg twice daily who had interruption for ,72 hours before surgery suggests accumulation of dabigatran in patients with renal impairment. However, data from RE-LY do not support this interpretation, because the same pattern of bleeding based on the timing of study drug interruption was seen in the subgroup of patients with an estimated creatinine clearance of ,60 mL/min. Instead, we believe that the ...

Discussion. The present study has highlighted the effect of various doses of carbendazim on the morphology of the magnum in the Japanese quail. This appears to be the first report of the effect of cytoskeletal-disrupting fungicide in the female reproductive tract of birds. The results show that carbendazim caused dose dependent morphological changes in the magnum. The minimum toxic dose determined in the current study was 400 mg/kg bodyweight carbendazim, which caused identifiable morphological changes in this section. Severe morphological changes were apparent when the dose of carbendazim was increased to 800 mg/kg bodyweight. Similar findings were observed in the male Japanese quail (Aire 2005), as well as in the rat, rabbit and hamster (Mantovani et al. 1998). No morphological changes were observed in birds treated with 25 mg/kg and 100 mg/kg bodyweight carbendazim. This could be due to rapid elimination of the carbendazim from body tissues. Elimination of carbendazim from animal tissues is ...
After a first description in 1975 of a strain of Haemonchus contortus resistant to the benzimidazole anthelmintics in South Africa, further strains of the same species developed resistance to rafoxanide and closantel, and a strain of Ostertagia species became resistant to the benzimidazoles. Recently five further strains of H contortus have been found which show resistance to these anthelmintics. Of these, four showed varying degrees of resistance to ivermectin and one was resistant to three anthelmintic groups. One of the strains became resistant to ivermectin very rapidly despite effective rotation of this anthelmintic with chemically unrelated anthelmintic compounds.. ...
Until recently, vitamin K antagonists were the only available oral anticoagulants, but with numerous limitations that prompted the introduction of new oral anticoagulants targeting the single coagulation enzymes thrombin (dabigatran) or factor Xa (apixaban, rivaroxaban, and edoxaban) and given in fixed doses without coagulation monitoring. Here we review the pharmacology and the results of clinical trials with these new agents in stroke prevention in atrial fibrillation and secondary prevention after acute coronary syndromes, providing perspectives on their future incorporation into clinical practice. In phase III trials in atrial fibrillation, compared with warfarin, dabigatran etexilate 150 mg B.I.D. reduced the rates of stroke/systemic embolism without any difference in major bleeding; dabigatran etexilate 110 mg B.I.D. had similar efficacy with decreased bleeding; apixaban 5 mg B.I.D. reduced stroke, systemic embolism, and mortality as well as major bleeding; and rivaroxaban 20 mg Q.D. was
Angiotensin II receptor blockers (ARBs), also known as angiotensin II receptor antagonists , AT1 receptor antagonists or sartans, are a group of pharmaceuticals that modulate the renin-angiotensin system. Their main uses are in the treatment of hypertension (high blood pressure), diabetic nephropathy (kidney damage due to diabetes) and congestive heart failure. They block the activation of AT1 receptors, preventing the binding of angiotensin II. Angiotensin II receptor blockers are used primarily for the treatment of hypertension where the patient is intolerant of ACE inhibitor therapy. They do not inhibit the breakdown of bradykinin or other kinins, and are thus only rarely associated with the persistent dry cough and/or angioedema that limit ACE inhibitor therapy.[citation needed] More recently, they have been used for the treatment of heart failure in patients intolerant of ACE inhibitor therapy, in particular candesartan. Irbesartan and losartan have trial data showing benefit in ...
Carbendazim is a widely used, broad-spectrum benzimidazole fungicide and a metabolite of benomyl. It is also employed as a casting worm control agent in amenity turf situations such as golf greens, tennis courts etc. and in some countries is licensed for that use only. The fungicide is used to control plant diseases in cereals and fruits, including citrus, bananas, strawberries, pineapples, and pomes. It is also controversially used in Queensland, Australia on macadamia plantations. A 4.7% solution of carbendazim hydrochloride, sold as Eertavas, is marketed as a treatment for Dutch elm disease. Studies have found high doses of carbendazim cause infertility and destroy the testicles of laboratory animals. Maximum pesticide residue limits (MRLs) have reduced since discovering its harmful effects. The MRLs for fresh produce in the EU are now between 0.1 and 0.7 mg/kg with the exception of loquat, which is 2 mg/kg. The limits for more commonly consumed citrus and pomme fruits are between 0.1 and 0.2 mg/kg.
The meta-analysis by Etminan and colleagues addresses an interesting question. Do angiotensin II receptor antagonists, similar to β-blockers, calcium channel blockers, and angiotensin-converting enzyme inhibitors (1, 2), reduce the frequency of headaches in patients with hypertension? The pooled results show a reduction in headache frequency with angiotensin II receptor antagonists. The findings should be interpreted with caution, however, because headache was not the primary outcome in any of the individual studies; the angiotensin II receptor antagonists chosen were not standardized; doses were not equivalent; and the definitions and types of headaches were not specified. Did the patients in these studies have tension headaches, migraine headaches, nasosinus headaches, or cluster headaches? Meta-analysis of secondary study endpoints should be considered hypothesis-generating, and the authors rightly call for a clinical trial to confirm the findings of this meta-analysis. The mechanism of ...
