Nuovi inibitori di Aurora chinasi A come target biologico coinvolto nei processi carcinogenici
Identificando Aurora chinasi A come target elettivo per l’inibizione dell’espansione tumorale è stato sfruttato l’approccio computazionale per effettuare un virtual screening su una libreria “in house” di strutture molecolari. L’analisi dei dati computazionali ha permesso di identificare nei derivati della serie pirido[3’,2’:4,5]furo[3,2-d]-1,2,3-triazin-4(3H)one di tipo 3 nuovi composti a potenziale attività inibitoria sul sito ATP-asico di Aurora chinasi A. La sintesi del sistema triciclico-eteroaromatico 3 prevede la diazotazione della 3-amino-furopiridina 1 e conseguente reazione di copulazione con una serie di ammine primarie opportunamente scelte, permettendo l’isolamento delle 3-tria…
Synthesis and antiproliferative activity of Naphtalenyl substituted 1,2-dihydropyrazol-5-one and related fused tetrazine
In recent years, besides the main field of nonsteroidal anti-inflammatory agents, the interest towards pyrazolone derivatives has been renewed because of their wide biological and pharmacological applications [1]. Currently, particular attention is focused on such a class of compounds due to the affinity with sigma receptor and their relationship with cancer [2].To these purposes we planned to design, synthesize and evaluate the antiproliferative activity (MTS assays) of a new series of 3-methyl-2-(1-R-naphthalen-2-yl)-1,2-dihydropyrazol-3-one derivatives 1 against HeLa, MCF-7, LAN-5, Caco2 in order to explore their anticancer potential. Additionally, further elaboration of the amino deriva…
DERIVATI TIENO[3,2-d]-1,2,3-TRIAZIN-4(3H)ONI ANELLATI:UNA NUOVA CLASSE DI INIBITORI DI AURORA CHINASI A
New benzothieno[3,2-d]-1,2,3-triazines with antiproliferative activity: synthesis, spectroscopic studies, and biological activity.
New benzothieno[3,2-d]-1,2,3-triazines, together with precursors triazenylbenzo[b]thiophenes, were designed, synthesized and screened as anticancer agents. The structural features of these compounds prompted us to investigate their DNA binding capability through UV–vis absorption titrations, circular dichroism, and viscometry, pointing out the occurrence of groove-binding. The derivative 3-(4-methoxy-phenyl)benzothieno[3,2-d]-1,2,3-triazin-4(3H)-one showed the highest antiproliferative effect against HeLa cells and was also tested in cell cycle perturbation experiments. The obtained results assessed for the first time the anticancer activity of benzothieno[3,2-d]-1,2,3-triazine nucleus, and…
Antiproliferative activity of Pyrrolo[3,2-c]quinoline derivatives
The pyrrolo[3,2-c]quinoline scaffold has been known as a core structure of a wide number of bioactive molecules. Several derivatives of such a tricyclic angular heterocycle have shown a wide spectrum of biological activities, such as hypotensive, anti-inflammatory properties, gastric (H)ATPase inhibition effect, and remarkable antitumor activity (1). The high therapeutic potentiality of such a skeleton along with our interest in targets featuring aza-polycondensed aromatic structures, attracted us to develop an alternative synthetic strategy, in order to reach a series of pyrrolo[3,2-c]quinolines in quantitative yields (2). The reaction of 3-acetyl-1,4-dione 1 with selected amines allowed th…
