Naringenin is a naturally occurring flavonoid and due to its broad spectrum of biological activities, including anticancer properties, has attracted scientific attention in recent years. To contribute to these studies, we synthesized some new (±)-naringenin cyclic aminoethyl derivatives, analyzed the cytotoxic and anti-proliferative properties of them via 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, and mitochondrial apoptosis signaling response and gene expressions belong to caspase-3 depended apoptosis as biomarkers in both healthy and cancer cell lines. Our results suggest that some of our naringenin derivatives are potential anticancer agents with a selective death potential and targeting properties for mitochondrial apoptosis signaling against at least human cervix and breast cancer.
A series of 1,3,5-trisubstituted isocyanurates (substituents: CH2CH2OH CH2CH=CH2 and CH2CH2COOH) was synthesized according to a modified literature procedure. Experimental investigations included modification of the synthetic procedure in terms of the starting materials, solvents, temperature isolation techniques, as well as purification and identification of the products. All the synthesized isocyanurates were identified by their melting point and FTIR, 1H NMR and UV spectroscopic data. Fourier transform infrared spectrophotometry was also used to study the interaction between ammonium perchlorate, hydroxyl terminated poly(butadiene), carboxyl terminated poly(butadiene), poly(butadiene-co-acrylonitrile), poly(propylene ether) cyclotrimethylenetrinitramine and the compounds synthesized in this work which can serve as bonding agents. The results show that tris(2-hydroxyethyl)isocyanurate is a universal bonding agent for the ammonium perchlorate/carboxyl terminated poly(butadiene)/cyclotrimethylenetrinitramine composite propellant system.
The title compound, C7H4F3NO2, 3-trifluoromethyl-1H-pyrrolo[1,2-c]oxazol-1-one, is the first crystal structure of the pyrrolo[1,2-c]oxazole ring system: the fused ring system is almost planar (r.m.s. deviation = 0.006 Å). In the crystal, weak C—H...O and C—H...F hydrogen bonds link the molecules into [001] chains and π–π stacking interactions consolidate the structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
