abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
the aim of the present study was to synthesis a series of phthalimides based on our previous works and examine their anxiolytic properties. using a three steps process, phthalimides were prepared from the corresponding di-methyl phthalate derivatives. phthalic anhydride was nitrated to produce 3-nitrophthalic acid. ring closer of either 3-nitrophthalic acid or di-methyl phthalate with urea were...

we describe here a suitable approach for the synthesis of n-unsubstituted monocyclic b-lactams under mild reaction conditions by the annelation of imines with substituted acetylchlorides. in this method the reaily available phtalimidoacetyl chloride were allowed to react with - dibenzylideneiminotoluene (hydrobenzamide) in the presence of an equimolar amount of triethylamine in refluxing toluen...

(E)-3-(1-Benzofuran-2-yl)propenoic acid (I) was prepared from 1-benzofuran-2-carbaldehyde under the Doebner’s conditions. The obtained converted to corresponding azide II, which cyclized by heating in diphenyl ether [1]benzofuro[3,2-c]pyridin-1(2H)-one (III). This compound aromatized with phosphorus oxychloride chloroderivative IV reduced zinc and acetic title V. [1]Benzofuro[3,2-c]pyridin-2-ox...
Several cycline dependent kinase 2 (CDK2) inhibitors with different chemical structures have been introduced. The hinge region of CDK2 (residues 81–84) contains a set of hydrogen bond donor and acceptor sites some of which must be satisfied for potent inhibitor binding. The benzimidazolone skeleton may provide such interactions. Accordingly, 3-sulfonamide substituted benzamido-benzimidazolones ...

It has been reported that sulfinamide anhydride is formed when anthranilic acid is treated with thionyl chloride under anhydrous conditions. Garin et al. reported that no sulfinamide anhydride was formed in the reaction of anthranilic acid with thionyl chloride. They reported that 2-(sulfinylamino) benzoyl chloride was formed, in accordance with an earlier observation, under the same reaction c...
