A novel heterocyclic compound belonging to 'triazine-aryl-bis-indoles', useful for the treatment of asthma. The pathway by which this compound inhibits asthma is also demonstrated. The present invention also provides a process for the preparation of above compound and its derivatives.
describes the synthesis of a novel class of compounds ‘triazine-aryl-bis-indoles’ having a catechol derived structure constituting a part of ‘triazine’ and a part of ‘bis-indole’ moiety on it. This class of molecules potently inhibited both phosphodiesterase IV and expression of cell adhesion molecules ICAM-1 and VCAM-1. The best molecule of this class (compound 11) inhibited PDE IV activity in vitro
与许多炎症相关的疾病一样,哮喘的病因复杂。在这些复杂的疾病中,针对多种途径的药物可能更有效。环状3',5'-单磷酸腺苷(cAMP)磷酸二酯酶IV(PDE IV)是支气管哮喘中经过验证的靶标之一,尽管有一些靶向PDE IV的治疗性分子可供使用,但仍需要具有更好性能的分子。嗜酸性粒细胞/嗜中性粒细胞向肺的浸润也可能是支气管哮喘的重要组成部分,其中上皮细胞粘附分子表达的增加可能起重要作用。这项研究描述了新型化合物“三嗪-芳基-双吲哚”的合成,该化合物具有邻苯二酚衍生的结构,构成“三嗪”的一部分和“双吲哚”部分的一部分。这类分子有效抑制磷酸二酯酶IV和细胞粘附分子ICAM-1和VCAM-1的表达。同类中最好的分子(化合物11)在体外抑制PDE IV活性, IC 50值为14μM,而现有药物咯利普兰的IC 50值为12.7μM。化合物11不仅在福司可林刺激后稳定了人肺上皮细胞(L132)中的cAMP
