Imidazo[1,2-a]pyridines and their use as pharmaceuticals
The present invention relates to derivatives of imidazo[1,2-a]pyridines of the formula (I),
in which R, R1 to R4 and n have the meanings indicated in the claims, which modulate the transcription of endothelial nitric oxide (NO) synthase and are valuable pharmacologically active compounds. Specifically, the compounds of the formula I upregulate the expression of the enzyme endothelial NO synthase and can be applied in conditions in which an increased expression of said enzyme or an increased NO level or the normalization of a decreased NO level is desired. The invention further relates to processes for the preparation of compounds of the formula I, to pharmaceutical compositions comprising them, and to the use of compounds of the formula I for the manufacture of a medicament for the stimulation of the expression of endothelial NO synthase or for the treatment of various diseases including cardiovascular disorders such as atherosclerosis, thrombosis, coronary artery disease, hypertension and cardiac insufficiency, for example.
咪唑[1,2-a]吡啶及其作为药物的用途。本发明涉及咪唑[1,2-a]吡啶衍生物的公式(I),其中R、R1至R4和n具有声明中指示的含义,这些衍生物调节内皮型一氧化氮(NO)合酶的转录,并且是有价值的药理活性化合物。具体来说,公式I的化合物上调内皮型NO合酶酶的表达,并可应用于需要增加该酶的表达或增加NO水平或正常化降低的NO水平的情况。该发明还涉及公式I化合物的制备方法,包括它们的药物组合物,以及公式I化合物用于制造刺激内皮型NO合酶表达或治疗各种疾病的药物,包括心血管疾病如动脉粥样硬化、血栓形成、冠状动脉疾病、高血压和心脏功能不全等。
