Full textThe Renin Angiotensin System plays a major role in cerebral circulation. AT1 receptor blockers (ARBs) afford protection against cerebrovascular complications that go beyond that to be expected from their blood pressure lowering action. Several mechanisms could explain such beneficial effects. Firstly, by blocking AT1 receptors, ARBs promote AT2 receptor stimulation by angiotensin II. The beneficial effect related to stimulation of AT2 receptors (vasodilation) counterbalances the deleterious actions of AT1 receptors stimulation. Changes in this ratio may then alter cerebral circulation. We demonstrated that the AT1- AT2 ratio is modified at the cerebrovascular level during high salt intake, which is a risk factor for stroke. The AT2-mediated vasodilation of pial arterioles is abolished. Secondly, some ARBs act as partial agonists of PPAR-gamma. Such an activity, which has been demonstrated to protect extracerebral vessels, could also be beneficial for cerebral circulation. Our results showed that PPAR-gamma activation improves ARB effects on cerebral circulation (arteriolar diameter, angiotensin II reactivity). The underlying mechanisms could imply functional regulation of AT1-AT2 receptors without any change in expression status. AT2 receptor stimulation and PPAR-gamma activity are two special properties of ARBs. These properties could contribute to the cerebroprotection induced by ARBs, beyond the AT1-receptor blockade. Development of new molecules with AT1-receptor blockade and PPAR-gamma activity could take part into the future therapeutic management of hypertension, providing a better cerebrovascular protection

Full textLa stratégie chimique utilisée a été la phase solide à l'aide d'une résine chlorure de trityle. La synthèse a été effectuée à partir de dérivés amino-acide protégés par un carbamate de fluorénylméthyle ou d'éthylène-oxy-triméthyle silicium permettant une déprotection en parallèle de la fonction amine une fois la fonction acide fixée à la résine. Nous avons obtenu une chimiothèque de 400 composés. A partir de ces 400 produits un hit a été identifié comme inhibiteur potentiel de l'aggrécanase 2. Des études de relations structures activités d'analogues de ce hit sont actuellement en cours.
En parallèle, comme le tétrazole fait partie des fonctions chimiques potentiellement ligand du zinc et est une fonction phare dans le développement d'inhibiteurs du récepteur à l'angiotensine 2 (AT1), nous avons développé une nouvelle technique de greffage de tétrazole sur résine et de synthèse de chimiothèque biphényltétrazole.Ces travaux ont permis la mise au point d'une nouvelle méthode de synthèse de biphényltétrazole en phase homogène au micro-onde et la synthèse innovante de dérivés biphényltétrazole en phase solide exemplifié par la synthèse de l'irbésartan en phase solide.
Nous avons ensuite développé des dérivés biphényltétrazole pyrazole. Pour cette famille de molécules, nous avons exploité les études effectuées sur la réaction de Buchwald que nous avons adaptée à nos composés. De plus ces mêmes travaux ont permis la mise au point d'une nouvelle réaction d'obtention de dérivés para-iodophényle pyrazole en une seule étape et qui ouvre une nouvelle voie rétrosynthétique de dérivés phényle pyrazole. Cinq de ces produits ont montré sur activité sur le récepteur AT1.

Full textIn the context of metabolic syndrome, development of Type 2 Diabetes is associated with (and influenced by) cardiac and renal comorbidities linked to micro- and macro-vasculature alterations. To assess the efficacy of new compounds on targeted organs in the context of metabolic syndrome, the Zucker fatty/Spontaneously hypertensive heart failure F1 hybrid (ZSF1) rat model could be suitable assuming cardiorenal alterations would develop in a short timeframe. Actually, the ZSF1 rat model recapitulates features of human metabolic syndrome, but develops relatively late (1year-time) and moderate cardiac and renal dysfunctions. The aim of our work was to exacerbate cardiorenal impairments in terms of onset and extent. Two options were explored. On one hand, unilateral nephrectomy was performed in ZSF1 rats, and cardiac and renal functions were longitudinally assessed. This surgical insult only significantly deteriorated renal function, which was prevented by standard of care, lisinopril and new renal protective agent, bardoxolone. On the other hand, subcutaneous infusion of angiotensin II (AngII) was used in the aim to induce hemodynamic and hormonal stress and thus to enhance cardiorenal impairments. AngII-infused ZSF1 rats displayed significant hypertension and increased levels of circulating aldosterone. Moreover, renal and cardiac functions dropped, concomitantly. We showed in this model that an aldosterone synthase inhibitor induced overall better renal protection than the mineralocorticoid receptor antagonist eplerenone. Our data showed that ZSF1-AngII rat is a suitable model to evaluate the cardio and renoprotective effects of drugs in the context of metabolic syndrome

Full textEvidence of regression of glomerulosclerosis in diabetic nephropathy (DN) and other modalities of chronic kidney diseases has been provided in recent years. However, it remains unclear whether advanced lesions such as glomerular sinechiae can be reversed with pharmacological therapy, or whether this possibility exists only for relatively moderate damage such as mesangial expansion. Recently, the protective renal effect of AT-1 receptor blockers (ARBs) was shown to be dose-dependent in chronic nephropathies. To verify whether an ARB possess a dose-dependent renal effect and whether glomerular lesions can regress in DN, rats were made diabetic by streptozotocin and treated with a standard and an extremely high dose of losartan (L). L treatment reduced albuminuria and protected against glomerulosclerosis and glomerular inflammation, without an additional effect with high doses. There was regression of mesangial expansion with L. However, there was no regression in the frequency of glomerulosclerosis with sinechiae. These findings suggest no dose-dependent effect of L in this model of DN and that mesangial matrix removal is a feasible aim with ARBs in DN.

Full textBackground: Clear cell renal cell carcinoma (ccRCC) are agressive tumors, with a bad prognosis when metastatic. Antiangiogenic treatments and especially tyrosine kinase inhibitors (TKI) have increasingly improve patients’ survival, but those drugs often present side effects like hypertension. Angiotensin-II stimulates tumor cell development and VEGF secretion via the type-1 receptor. In different types of cancer, angiotensin-II type 1 receptor antagonists (ARA-2) used as antihypertensive drugs can reduce tumor cell proliferation and inhibit neoangiogenesis. Objective: Develop different xenograft animal models of ccRCC, and test the efficacy of sunitinib (TKI) combined with telmisartan (ARA-2).Material & Methods: Nude mice have been injected sub-cutaneously with 786-O cells. Mice have been divied into 4 groups and received orally every day during 4 weeks: DMSO, telmisartan , sunitinib or the combination of sunitinib and telmisartan. Then animals were sacrified and their tumor was analyzed. In a second part using primary cell lines, a new mouse model was developed and tested.Results: In the first model, combined treatments (TKI+ARA-2) increased tumor necrosis, reduced microvascular density and circulant VEGF secretion. In the model developed with primary cell lines, there was a reduction in tumor growth but without increasing tumor necrosis. Conclusion: In this work, 2 different animal models of ccRCC have been developed. Sunitinib combined with telmisartan seems to potentiate anti-tumoral effects in these animal models. Further analyses are warranted to understand the different mechanisms implicated

Full textAcute coronary syndrome (ACS) causes approximately 100,000 hospitalisations per year in France. In secondary prevention of ACS, guidelines advocate pharmacological treatment combining four drug classes: beta-blockers, antiplatelet agents, statins and angiotensin converting enzyme inhibitors or angiotensin receptor blockers (recommended combination).The aim of this work was to study, in real life and among the general population, the use and the effectiveness of the recommended combination for secondary prevention of ACS.Firstly, we explored the potential represented by the French claims databases in this context. Secondly, we studied the use of the recommended combination: 42% of patients were treated with the recommended combination in post-ACS and 57% of them were still treated two years after; persistence to combination was lower in older patients, in those with other comorbidities and those who had an ACS different of myocardial infarction. Thirdly, we studied the effectiveness of the recommended combination: the recommended combination was the most effective combination therapy at long-term in post-ACS patients with history of heart failure; in patients without such history the combination without betablockers was not associated with an increased risk. These results could help reconsidering the long-term interest of the full recommended combination in all ACS patients and highlight the need to strengthen patient education strategies

Full textIntrodução: A nefropatia diabética é um processo patológico consequente do estado crónico de hiperglicémia por que passam os doentes diabéticos. Através de diferentes mecanismos vão ocorrendo ao longo do tempo alterações irreversíveis na estrutura do glomérulo renal que a longo prazo levam à insuficiência renal crónica. Dentro das várias estratégias existentes para diminuir a incidência e a progressão desta complicação da diabetes mellitus, o recurso aos inibidores da enzima de conversão da angiotensina e aos antagonistas dos receptores da angiotensina II já é há muito utilizado e tem sido objecto de estudo com resultados muito satisfatórios. Objectivo: Este trabalho pretende rever tanto os efeitos destes dois grupos de fármacos, a sua eficácia e segurança, tal como o melhor meio de utilização dentro das diferentes associações de agentes que são utilizadas de modo a potenciar os benefícios renais em doentes diabéticos. Desenvolvimento: O efeito principal dos inibidores da enzima de conversão da angiotensina e dos antagonistas dos receptores da angiotensina II consiste na diminuição da tensão arterial conseguida através da inibição do eixo renina-angiotensina-aldosterona. São inibidos tanto os efeitos vasoconstritores da angiotensina II tal como a libertação de aldosterona que é responsável por aumentar a reabsorção de sódio a nível do nefrónio. A diminuição da pressão arterial daí resultante, juntamente com a redução na pressão intraglomerular produzida, leva tanto ao abrandamento da lesão renal crónica tal como à diminuição da filtração de albumina no glomérulo, que é lesiva para a membrana basal por si só. Através de estudos comparativos de diferentes agentes com grupos placebo procura-se extrair conclusões quanto à sua interferência no processo patológico, utilizando medidas de avaliação tal como a detecção de albumina na urina, de taxas de filtração glomerular, os níveis de tensão arterial ao longo do tratamento e ainda o tempo de evolução entre os diferentes estadios da doença. Conclusão: Ambos os grupos são ferramentas imprescindíveis na prevenção e tratamento da nefropatia diabética. Eles revelaram que comparativamente a outros fármacos têm uma capacidade maior em reduzir a progressão da lesão renal ao atrasar a instalação tanto da microalbuminúria, da macroalbuminúria e mais tarde mesmo da insuficiência renal crónica. Existem diferentes vantagens e desvantagens em usar estes agentes em diferentes associações tendo de se estudar o tipo de doente que se está a tratar para que beneficie do melhor tratamento possível
Introduction: The diabetic nephropathy is a pathological process resulting from a chronic state of hyperglycemia which diabetic patients suffer. Due to different mechanisms irreversible changes will occur in the glomerular structure that will eventually lead to chronic renal failure. Among the different strategies to diminuish the incidence and progression of this diabetic complication, the use of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers is very common and has been studied with very satisfying results. Objective: This work aims to review the effects of these two groups of pharmacological agents, their efficiency and security, as well as the best way of combining them with other agents to achieve the best renal outcomes in diabetic patients. Development: The main effect of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers is the lowering of arterial pressure achieved by the inhibition of the renninangiotensin- aldosterone system. Not only are the vasocronstrictor effects fo angiotensin II blocked but also the releasing of aldosterone which is responsible for renal sodium reabsortion. These actions lead to lower blood pressure levels and lower intraglomerular pressure that will slow the rate of albumin excretion and progression of renal damage. Using comparative studies of these agents with placebo groups many conclusions can be drawn of their interference in the pathological process, by measuring albumin in the urine, the glomerular filtration rate, blood pressure levels and the time of progression through the different stages of the disease. Conclusion: Both groups are key elements in the prevention and treatment of diabetic nephropathy. In comparison to other agents they have a more efficient capacity to decrease the progression of renal damage by slowing the incidence of microalbuminuria, macroalbuminuria and even chronic renal failure. There are both advantages and disadvantages by combining these agents with other groups depending on the kind of patient that is being treated.

Angiotensin II type I receptor antagonists are now widely in hypertension pharmacotherapy. The angiotensin receptor blockers (ARB), including valsartan, losartan, irbesartan, telmisartan, candesartan, olmesartan, eprosartan, are substrates of OATP transporters. These drugs are in general effective and safe, but they have difference in selectivity of hepatic uptake transporters. To a patient who has poor response to an ARB, a larger dose is often prescribed. We postulated that OATP polymorphism may affect drug response of certain ARB's. If a pharmacogenetic (genotyping or phenotyping) method can be used to find that the poor response is due to OATP SNP's, other ARB's or other classes of antihypertensive can be used instead to obtain a good control of blood pressure. To study the inter-individual variation of ARB's, after the protocol reviewed by NCKU IRB, we have recruited 62 healthy volunteers for pharmacodynamic studies. Five ARB's, valsartan, losartan, irbesartan, telmisartan, olmesartan were given in separate occasions. Blood pressure response was measured after dosing. The relative response of five ARB's was statistics by multiple regression. Among them, 19 subjects carried at least one OATP1B1*15 allele and 43 subjects had either OATP1B1 *1a or *1b allele. Additionally, we also analysis SNP of OATP1B3 and OATP2B1. We found that had significant difference response to olmesartan between subjects with SNP of OATP2B1 and losartan between subjects with SNP of OATP1B3. However, we didn’t found that had a significant difference response to the five ARBs between subjects with SNP of OATP1B1. Additionally, we also found that had significant difference response to certain ARBs with gender and age difference.
