This study aims at investigating a synthesis approach based on molecular hybridization strategy through grafting an nitric oxide-releasing moiety, oxime, to coumarin–chalcone hybrids. In vitro anti-proliferative activity of some of the prepared compounds showed moderate activity (growth inhibition values = 45.85, 40.86, 39.25 for compound 8a against leukemia, Central Nervous system and breast cancer cells, respectively). Also, IC50 = 9.62 and 14.40 for compounds 8h and 8f, respectively against breast Michigan Cancer Foundation-7 cell lines. The antibacterial screening results suggest a possible role for nitric oxide in enhancement of the antibacterial activity where nitric oxide is not the only factor but other factors like physicochemical properties should be investigated for their potential role on the activity.
