本文介绍了一系列新型的双杂环双酰胺的合成,体外脲酶抑制和计算机分子对接研究。标题化合物的合成是通过在弱碱性水性介质中,将关键起始剂2-(2-氨基-1,3-噻唑-4-基)乙酸乙酯(2)与苯甲酰氯(1)进行苯甲酰化反应开始的,然后酰肼的形成4,并与CS2环化以形成母体双杂环亲核试剂N- {4-[(5-硫烷基-1,3,4-恶二唑-2-基)甲基] -1,3-噻唑- 2-基}苯甲酰胺(5)。通过两步法合成了各种亲电试剂8a-1,最后将它们与5偶联,得到了目标双杂环双酰胺分子9a-1。通过IR,1 H NMR,13 C NMR,EI-MS和元素分析证实了新合成产物的结构。这些分子对脲酶的体外筛选研究表明,大多数化合物均显示出对该酶的有效抑制潜力。相对于IC50值为21.11±0.12 µM的标准硫脲,化合物9j的IC50值为2.58±0.02 µM,显示出最有希望的抑制活性。在计算机研究中,充分增强了

Modifications at the basic nitrogen of the benzomorphan scaffold allowed the development of compounds able to segregate physiological responses downstream of the receptor signaling, opening new possibilities in opioid drug development. Alkylation of the phenyl ring in the N-substituent of the MOR-agonist/DOR-antagonist LP1 resulted in retention of MOR affinity. Moreover, derivatives 7a, 7c, and 7d
Disclosed are novel heterocyclic derivatives, useful for the treatment of various disease states, in particular cardiovascular diseases such as atrial and ventricular arrhythmias, intermittent claudication, Prinzmetal's (variant) angina, stable and unstable angina, exercise induced angina, congestive heart disease, and myocardial infarction. The compounds are also useful in the treatment of diabetes.
The present invention relates to a compound of formula (I)
and salts thereof, process for preparation thereof, to compositions containing the same and to the use of such a compound in the treatment of various diseases, such as allergic rhinitis.
