Synthesis And Biological Evaluation

A series ofN-nitro acid amide derivatives compounds were synthesized based on the active site of target acetohydroxyacid synthase (AHAS, EC: 2.2.1.6) enzyme. All the structures of newly prepared compounds were thoroughly characterized by satisfied IR and1H NMR spectra. The IC50values against AHAS enzyme and EC50values for herbicidal activity againstAmaranthus mangostanus L.andSorghum sudanenseof all synthesized target compounds were determined. The compoundsII-10,II-21, andII-22with IC50values of 7.09 mg/L, 9.07 mg/L, and 9.11 mg/L and the compoundsII-8andII-22with EC50values of 9.87 mg/L and 19.88 mg/L against root ofAmaranthus mangostanus L.andSorghum sudanensewere illustrated, respectively. Meanwhile, the possible reasons for the lower activity of compounds were analyzed by molecular docking prediction.

AbstractA series of urolithins derivatives were designed and synthesized, and their structures have been confirmed by 1H NMR, 13C NMR, and HR-MS. The inhibitory activity of these derivatives on phosphodiesterase II (PDE2) was thoroughly studied with 3-hydroxy-8-methyl-6H-benzo[C]chromen-6-one and 3-hydroxy-7,8,9,10-tetrahydro-6H-benzo[C] chromen-6-one as the lead compounds. The biological activity test showed that compound 2e had the best inhibitory activity on PDE2 with an IC50 of 33.95 μM. This study provides a foundation for further structural modification and transformation of urolithins to obtain PDE2 inhibitor small molecules with better inhibitory activity.

Aurones belong to a class of heterocyclic flavonoids which contains a benzofuran element associated with a benzylidene linked in position 2. Aurones possess a wide range of pharmacological activities and biological activities, such as antitumor, antifungal, phytoalexin and so on. A novel series of 2-ayl-yl (5-methacrylate) aurone analogues were synthesized in six steps with the overall yield of 11%-13% and characterized by 1H NMR. Among the key intermediates and target compounds, 2-(2-furan-ylmethylene)-5-methacrylate-benzofuran-3(2H)-one (7a) and 2-(2-thienyl-ylmethylene)-5-methacrylate-benzofuran-3(2H)-one (7b) have never been reported before. Primary biological activities evaluation showed that 7a exhibited good inhibitory activities against K562 with an IC50 of 2.18 μM and against HepG2 with an IC50 of 3.95μM.
