摘要： Twenty-five novel pregnenolone/2-cyanoacryloyl conjugates (6-30) were designed and prepared, with the aim of developing novel anticancer drugs with dual NF-kappa B inhibitory and anti-proliferative activities. Compounds 22 and 27-30 showed inhibition against TNF-alpha-induced NF-kappa B activation in luciferase assay, which was confirmed by Western blotting. Among them, compound 30 showed potent NF-kappa B inhibitory activity (IC50 = 2.5 mu M) and anti-proliferative against MCF-7, A549, H157, and HL-60 cell lines (IC50 = 6.5-36.2 mu M). The present study indicated that pregnenolone/2-cyanoacryloyl conjugate I can server as a novel scaffold for developing NF-kappa B inhibitors and anti-proliferative agents in cancer chemotherapy.
