Abstract We direct for the synthesis of 1,6,7-trisubstituted-4-phenylthiazol-2(3H)-ylidene)hydrazono)methyl)quinolin-2-one derivatives by the reaction of corresponding thiosemicarbazone derived by 2-quinolone derivatives with 2-bromoacetophenones in presence of triethylamine at room temperature. The mechanism of the formed products was discussed. The structure of the obtained products was fully characterized
Pyrano[3,2-c]quinolone structural motifs are commonly found in natural products with diverse biologicalactivities. As part of a research programme aimed at developing the efficient synthesis of natural product-like small molecules, we designed and developed the microwave assisted, facile stereoselective synthesis of two series of carbohydrate fused pyrano[3,2-c]quinolonederivatives (n = 23) starting
吡喃并[3,2- c ]喹诺酮的结构基序通常存在于具有多种生物活性的天然产物中。作为旨在开发类似于天然产物的小分子的有效合成研究计划的一部分,我们设计并开发了微波辅助的两种系列碳水化合物融合的吡喃并[3,2- c ]喹诺酮衍生物(n = 23)从2- C-甲酰基半乳糖和2- C-甲酰基葡糖开始,在较短的反应时间(15-20分钟)内与各种4-羟基喹诺酮类反应。这些合成的吡喃并[3,2- c确定了针对MCF-7(乳腺癌)和HepG2(肝)癌细胞的喹诺酮类药物。选定的文库成员显示出低摩尔浓度(3.53–9.68μM)和选择性的抗增殖活性。这些关于碳水化合物稠合的吡喃并[3,2- c ]喹诺酮衍生物的发现有望为抗癌药物的发现提供新的线索。

AbstractQuinoline-2,4-diones reacted with 2-[bis(methylthio)methylene]malononitrile in DMF/Et3N to produce 3-(methylthio)-4-oxo-4,5-dihydrofuro[3,2-c]quinolone-2-carbonitriles and 3-(methylthio)-4-oxo-4,5-dihydrofuro[3,2-c]quinolone-2-carboxamides in state of 2-imino-substituted 4-(methylthio)-5,6-dihydro-2H-pyrano[3,2-c]quinolone-3-carbonitriles. The structures of all new products were proved using NMR
