Abstract:
A series of novel ATB-429 (an anti-inflammatory candidate) derivatives containing a nitric oxide (NO)-releasing moiety were designed, synthesized and evaluated for their in vitro activity against six human cancer cell lines. Our results reveal that phenylsulfonylfuroxan-based derivatives have considerable antitumor activity, and compounds 7-9 (IC50s: 0.256-3.024 μM) against HT-29 and PANC-1, 8a,b (IC50s: 2.677-3.051 μM) against MCF-7 and 8a (IC50: 1.270 μM) against DU145 are more active than Vandetanib (IC50s: 1.925-4.107 μM).

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
