We describe preparation of compounds of an AT1 receptor antagonist(s) and Angiotensin (1-7), for example, Angiotensin-(1-7) losartanate and analogues thereof, and/or mixtures of these systems, pharmaceutical compositions thereof and use of their derivative products. Cyclodextrins and derivatives thereof may be used for the micro-encapsulation of compounds, for example, Angiotensin (1-7) losartanate, liposomes and biodegradable polymers and/or mixtures of these systems and/or derivative products for the obtainment of nano- or microparticles as controlled or sustained release devices of Ang-(1-7) losartanate and analogues and/or mixtures thereof. The compounds may be used as agents for treating or preventing hypertension, cardiovascular diseases, heart hypertrophy, heart failure, coronary diseases, such as angina pectoris, endothelial disorder or endothelial lesions, as a consequence, for example, of atherosclerosis processes or in association with diabetes mellitus. They may also be used in the study and therapy of cardiovascular, renal, reproductive, dermatological, neoplastic, blood and cerebral diseases, and when formulated in controlled release systems, encapsulated or not in cyclodextrins, for use in stent, with a view to modulate the growth of the neointima after catheterization procedures.
我们描述了制备AT1受体拮抗剂和
血管紧张素(1-7)的化合物的方法,例如,
血管紧张素(1-7)洛卡
特普和其类似物和/或这些体系的混合物,以及其衍生产品的制药组合物和使用方法。
环糊精及其衍
生物可用于化合物的微囊化,例如,
血管紧张素(1-7)洛卡
特普,脂质体和
生物可降解聚合物和/或这些体系和/或衍生产品的混合物,以获得纳米或微粒子作为Ang-(1-7)洛卡
特普和其类似物和/或这些体系的控制或持续释放装置。这些化合物可用作治疗或预防高血压,心血管疾病,心肌肥大,心力衰竭,冠心病(如心绞痛),内皮紊乱或内皮损伤的药物,例如,由动脉粥样硬化过程引起或与糖尿病有关。它们还可用于心血管,肾脏,生殖,皮肤,肿瘤,血液和脑部疾病的研究和治疗,当制成控制释放系统,不管是否被微囊化在
环糊精中,用于支架,以调节导管手术后新内膜的生长。
