Efforts were taken to synthesis and characterize 2-amino-1-methyl-1H-imidazole-4(5H)-one derivatives (4a-u) through a four-step reaction. The achieved compounds in remarkable yield have characterized through standard analytical techniques such as FTIR, LC-MS, NMR, HRMS, and elemental analysis. Present study mainly aimed to evaluate 4a-u as G protein-coupled receptors (GPCR). In the mechanism, stimulation
努力通过四步反应合成并表征了2-amino-1-methyl-1H-imidazole-4(5H)-one衍生物(4a-u)。通过标准分析技术(例如FTIR,LC-MS,NMR,HRMS和元素分析)对获得的化合物以惊人的收率进行了表征。目前的研究主要旨在评估4a-u作为G蛋白偶联受体(GPCR)。在该机制中,磷酸肌醇3激酶(PI3K)和Akt(蛋白激酶B)的刺激是由一系列膜结合受体(如GPCR)激活的一般反应。蛋白酶激活受体1(PAR1)是相关GPCR的一个亚家族,由其胞外域片段的分裂触发。因此,进行分子对接以确保抑制PAR1和PI3Kinase。PI3激酶是通过Akt / mTOR途径在乳腺癌发展中的主要酶。因此,体外PI3激酶抑制和抗乳腺癌研究也已经进行了筛选,以从(4a-u)中筛选出医学上重要的化合物。基于最佳结合亲和力,体外相对活性百分比和IC50值,筛选出化合物4a,4g,4i,
