Paragraph 0076-0079, (2019/04/04)
The invention discloses 2,3-dihydro-1H-quinoline-4-ketone thiosemicarbazone derivatives as well as a preparation method and application thereof. The structural formula of the derivatives is as shown in a formula (I): (the formula is as shown in the description), wherein R1 is halogen, alkyl or alkoxy; R2 is hydrogen, halogen or alkoxy; R3 is hydrogen or halogen; R4 is hydrogen or halogen; X is hydrogen, acetyl or nitryl; and Y is hydrogen or phenyl. The derivatives can obviously inhibit proliferation of tumor cells, and has significant inhibition effect on multiple cancer cell strains such asbreast cancer cells, melanoma cells and prostatic cancer cells; and the anti-tumor activity is obviously better than that of a broad-spectrum anti-cancer medicine cis-platinum. In addition, the preparation process of the derivatives is simple, the conditions are mild, the sources of the raw materials are rich, the production cost is low, and potential medicinal value and good application prospectin the aspect of preparing a novel anti-tumor medicine are achieved.

, p. 753 - 760 (2008/02/04)
Interaction of 2-and 4-fluorophenylamines with acrylic and itaconic acids leads to the synthesis of the corresponding N-substituted β-alanines, the cyclization of which leads to derivatives of dihydropyrimidinone, 4-carboxy-2-pyrrolidinone, and tetrahydro
