Design, synthesis and biological evaluation of novel quinazoline derivatives as potential NF-κb inhibitors

Abstract

A series of novel 4-aminoquinazoline derivatives were designed, synthesized and biological properties on nuclear factor-kappaB (NF-κb) pathway inhibitory and potential in vitro anti-proliferation against breast cancer lines were also evaluated. Among them, LU1501 exhibited potent inhibition with IC50 values in SK-BR-3 (10.16 ± 0.86 µM) and HCC1806 (10.66 ± 1.01 µM) cell lines. In vivo studies in breast cancer tumor model proved the correlation between anticancer activity of LU1501 and proliferation inhibition through the NF-κb signal pathway. The molecular docking studies also portrayed the potential binding mechanism between LU1501 and the key proteins of p65 and IkBα in NF-κb pathway. Accordingly, compound LU1501 could serve as a potent agent against breast cancer for further investigation.
