The following study, which is the topic of my PhD research, highlights the synthesis and the antineoplastic activity of a range of polycyclic aromatic hydrocarbons (PAHs) whit isoxazolidinyl, isoxazolinyl and isoxazolyl moieties. The compounds have been prepared through 1,3-dipolar cycloaddition reaction of nitrones and nitrile oxides with differently substituted dipolarophiles. The antitumoral activity has been evaluated over three cell lines (HeLa, HN6, HN13) using MTS assay. The results show that the isoxazolidine derivatives exhibit the best activity. Particularly, compound (3R,5S)-2-(2-methoxybenzyl)-3-(1,10-phenanthrolin-2-yl)isoxazolidin-5-yl)methanol shows a IC50 of 4.5 µM toward HN13 cells and it is able to inhibit topoisomerase I.
Nel lavoro oggetto della tesi di dottorato viene riportata la sintesi e l attività antineoplastica di una serie di idrocarburi policiclici aromatici (IPA) a core isossazolidinico, isossazolinico ed isossazolico. I composti sono stati preparati per cicloaddizione 1,3-dipolare di nitroni e nitril ossidi con dipolarofili variamente sostituiti. L attività antitumorale è stata valutata su tre linee cellulari (HeLa, HN6, HN13) mediante saggio MTS. I risultati ottenuti mostrano che i derivati isossazolidinici presentano le migliori proprietà; in particolare, il (3R,5S)-3-(1,10-fenantrolin-2-il)-2-(2-metossibenzil)-isossazolidin-5-il)metanolo esibisce una IC50 pari a 4,5 µM sulla linea cellulare HN13 ed è capace di inibire la topoisomerasi I.

Abstract
The following study, which is the topic of my PhD research, highlights the synthesis and the antineoplastic activity of a range of polycyclic aromatic hydrocarbons (PAHs) whit isoxazolidinyl, isoxazolinyl and isoxazolyl moieties. The compounds have been prepared through 1,3-dipolar cycloaddition reaction of nitrones and nitrile oxides with differently substituted dipolarophiles. The antitumoral activity has been evaluated over three cell lines (HeLa, HN6, HN13) using MTS assay. The results show that the isoxazolidine derivatives exhibit the best activity. Particularly, compound (3R,5S)-2-(2-methoxybenzyl)-3-(1,10-phenanthrolin-2-yl)isoxazolidin-5-yl)methanol shows a IC50 of 4.5 µM toward HN13 cells and it is able to inhibit topoisomerase I.File | Dimensione | Formato | |
