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.

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.

Abstract Twelve N-((2-phenyloxazol-4-yl)methyl) pyrimidine carboxamide derivatives were designed, synthesized, and characterized by 1H NMR, 13C NMR, and HRMS. The fungicidal activities of these new compounds against Sclerotinia sclerotiorum, Botrytis cinereal, and Colletotrichum fragariae were evaluated. The results indicated that compounds 5b, 5f, and 5g displayed potential fungicidal activities against tested fungi, especially 5f exhibited IC50 value of 28.9 mg/L against S. sclerotiorum. Moreover, the compounds 5f and 5g showed IC50 values of 54.8 mg/L and 62.2 mg/L against C. fragariae respectively, which shows that they were more active than the commercial fungicide hymexazol. The superficial structure-activity relationships were discussed, which may be of benefit for the development of fungicides and discovery of novel fungicides.

Abstract A new class of β-lactam pharmacophore series of 2-Bromo-N-[4-(2-{[2-(substituted phenyl)-3-chloro-4-oxoazetidin-1-yl] amino}-2-oxoethyl) phenyl] pyridine-4-carboxamide derivatives were designed, prepared, and screened for their antimycobacterial activities. The hydrazone derivatives were first synthesized via conventional and microwave methods, and then the β-lactam ring could be constructed via a [2+2] ketenimine cycloaddition. The structure of all synthesized compounds was characterized by FTIR, 1H NMR, 13C NMR, and Mass spectroscopy techniques. All the newly synthesized derivatives were found to be effective in inhibiting M. tuberculosis H37RV strain infection at concentrations of 12.5, 25.0, and 50.0 µg/mL using the MABA method. Amongst, the compound (6e) was found to be good potent antitubercular activity at 12.5 mg/mL concentration in comparison with the rest of the compounds using the standard therapeutic agent Streptomycin. Molecular dynamics simulation studies and Molecular docking studies have been performed against mycobacterial InhA enzyme to gain an insight into the possible mechanistic action in search of good potent antitubercular candidates.
