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.
Relationship between anticonvulsant activity and enzyme inhibitory effectiveness of substituted oxadiazoles

Eight 2-(2,6-dimethylphenoxymethyl)-5-arylamino-1,3,4-oxadiazoles were synthesized. All oxadiazoles (100 mg/kg, ip) possessed anticonvulsant activity. This was reflected by 10-60% protection observed against pentylenetetrazol (90 mg/kg, sc)-induced convulsions in mice. All oxadiazoles also inhibited in vitro respiratory activity of rat brain homogenates. The antiproteolytic activity of these oxadiazoles was reflected by their ability to provide protection against in vitro trypsin-induced hydrolysis of bovine serum albumin and this ranged from 21% to 44% at a final concentration of 0.5 mM. All oxadiazoles (2 mM) inhibited in vitro succinate dehydrogenase activity of rat brain homogenates and the degree of inhibition ranged from 25-86%.
