Two series of ω-phenoxy contained acylhydroxamic acids as novel urease inhibitors were designed and synthesized. Biological activity evaluations revealed that ω-phenoxypropinoylhydroxamic acids were more active than phenoxyacetohydroxamic acids. Out of these compounds, 3-(3,4-dichlorophenoxy)propionylhydroxamic acid c24 showed significant potency against urease in both cell free extract (IC50 = 0.061 ± 0.003 μM) and intact cell (IC50 = 0.89 ± 0.05 μM), being over 450- and 120-fold more potent than the clinically prescribed urease inhibitor AHA, repectively. Non-linear fitting of experimental data (V-[S]) suggested a mixed-type inhibition mechanism and a dual site binding mode of these compounds.

Some novel pyrazole derivatives were designed and synthesized through multi-step reactions from substituted phenol as starting material. Their structures were confirmed by 1H NMR, FTIR, MS and elemental analysis. All these compounds were evaluated their herbicidal activity. The preliminary bioassay results indicated that some of title compounds displayed moderate herbicidal activity at 200 μg/mL. Among them, compounds 4-chloro-N'-(2-(2,5-dimethyl-phenoxy) acetyl)-3-ethyl-1-methyl-1H-pyrazole-5-carbohydrazide, 4-chloro-N'-(2-(2,4-dichlorophenoxy)acetyl)- 3-ethyl-1-methyl-1H-pyrazole-5-carbohydrazide, 4-chloro-3-ethyl-1-methyl-N'-(2-(m-tolyloxy) acetyl)-1H-pyrazole-5-carbohydrazide and 4-chloro-3-ethyl-1-methyl-N'-(2-(3-nitrophenoxy)acetyl)- 1H-pyrazole-5-car-bohydrazide possessed 95%, 100%, 95% and 95% inhibition against Brassica campestris respectively. In the further bioassay, the compound 6l exhibited excellent herbicidal activity either monocotyledon or dicotyledon plant at 150 g/ha.
