Synthesis and antiproliferative activity of a natural like glycoconjugate polycyclic compound

2016

Abstract A natural like O -glycoconjugate polycyclic compound 4 was obtained by a multistep procedure starting from N -(3-methyl-1-(4-nitrophenyl)-1 H -pyrazol-5-yl)acetamide. The glycosyl derivative 4 showed antiproliferative activity against all the tumoral cell lines of the NCI panel in the range 0.47–5.43  μ M. Cytofluorimetric analysis performed on MDA-MB231, a very aggressive breast cancer cell line, which does not express estrogen, progesterone and HER-2/neu receptors, showed that 4 is able to induce prolonged cell cycle arrest at G2/M phase and morphological signs of differentiation. These events are correlated with down-regulation of both cyclin B1 and cdc2, the cyclins involved in…

Synthesis and antiproliferative activity of a natural like glucosyl polycyclic compound

2014

A new polycylic compound was synthesized and evaluated for its antiproliferative activity against the NCI panel of human tumoral cell lines showing IC50 values in the range 0.47-5.43 µM. The compound induced a decrease of the level of cyclin B1, whereas increased the level of the inhibitor p21 WAF1

New complex polycyclic compounds: Synthesis, antiproliferative activity and mechanism of action

2020

Abstract Polycyclic or O-glycoconiugate polycyclic compounds 1a-g were previously tested for their in vitro antiproliferative activity. In this series of compounds, activity increases as log P decreases. Specifically, compounds 1d and 1g showed lower log P values together with the best antiproliferative profiles. With the aim of extending our understanding of the structure–activity relationship (SAR) of this class of compounds, we prepared new polycyclic derivatives 2a-c, which bear on each of the two phenyl rings hydrophilic substituents (OH, SO2NH2 or NHCOCH3). These substituents are able to form hydrogen bonds and to decrease the partition coefficient value as compared with compound 1d. …
