A series of 2-amino-5,6,7,8-tetrahydroquinoline-3-carbonitriles 4a–c has been synthesized and reacted with various reagents. Docking studies into the catalytic site of p38 mitogen activated protein kinase (MAPK) were used to identify potential anti-inflammatory lead compounds. The anticipated lead derivative 2-(pyridin-3-yl)-5-(4-methoxyphenyl)-6,7,8,9-tetrahydropyrimido[4,5-b]quinolin-4-amine 9b was endowed with good binding energy. Also, the obtained products were evaluated for their in vivo anti-inflammatory activity as prostaglandin inhibitiors (% inhibition of edema and % inhibition of plasma PGE2 at the two dose levels were determined). The tested compounds exhibited significant anti-inflammatory activity and minor ulcerogenic effects, when compared to the reference standard indomethacin, with product 9b being of particular interest.
已合成一系列2-氨基-5,6,7,8-四氢喹啉-3-羧腈4a–c,并与多种试剂反应。通过对接研究进入p38丝裂原活化蛋白激酶(MAPK)的催化位点,以鉴定潜在的抗炎先导化合物。预期的先导衍生物2-(吡啶-3-基)-5-(4-甲氧基苯基)-6,7,8,9-四氢嘧啶并[4,5-b]喹啉-4-胺9b具有良好的结合能。此外,所得产物作为前列腺素抑制剂进行了体内抗炎活性评估(在两种剂量水平下测定对水肿的抑制百分比和血浆PGE2的抑制百分比)。与参考标准吲哚美辛相比,所测试的化合物表现出显著的抗炎活性且只有轻微的致溃疡作用,其中产品9b特别引人关注。
