organophosphorus chemicals are compounds which have been used as pesticides and insecticides in agriculture. they’re also used as nervous agents and have raised many problems for human and environment. among the most important methods of decontamination from these compounds are biodegradation methods. using oph enzyme in degradation the mentioned compounds is seen as one of the desirable ways, ...

The Series of 3-(Substitutedphenyl)-N-(4H-1,2,4-triazol-4-yl)acrylamide compounds were prepared byreaction of 4-amino-1,2,4-Triazole with Acetyl Chloride followed by Claisen-Schmidt Condensation reactionwith different aromatic aldehydes. The structures of new compounds were confirmed by IR, 1H-NMR and13C-NMR spectral data. Anti-bacterial and Anti-fungal activities were evaluated and compared wi...

Displacement reaction of 2,3-dichloroquinoxaline with secondary amines in boiling ethanol afforded it`s mono aminoquinoxaline derivatives. Further reaction of the latter compounds with sodium azide in warm dimethylsulfoxide achieved a group of 4-amino tetrazolo[1,5-a]quinoxaline derivatives. 1HNMR spectra of these compounds are discussed.

Among the most important problems of pistachio are physiological disorders such as fruit abscission and production of blank nuts. Environmental stresses and inadequate nutrition during flowering time have increased these problems in recent years. In order to evaluate the effects of foliar treatments with polyamines and other compounds (amino acids and ascorbic acid) on quantitative and qualitat...

a facile one step synthesis of anilino alky1-n-substituted phthalimide i is reported. the following compounds belonging to this series were made: 1. (anilino-n-ethyl) phthalimide 8 2. (3,4, 5-trimethoxy anilino-n-ethyl) phthalimide 6 3. (3,4, 5-trimethoxy anilino-n-propyl) phthalimide 7 4. n-(ethyl phthalirnido-p-amino benzoyl) glutamic acid diethyl ester 10 5. n-(propyl phthalimido-p-amino ben...

Many studies have paid particular attention to the role of either secondary plant compounds or amino acids as determinants of host-plant range in phytophagous insects. Here we examine the relative importance of both of these classes of compound in host acceptance by generalist and specialist morphs of the black bean aphid, Aphis fabae, that are morphologically similar and genetically identical....
