Background:The spread of drug-resistant microbial strains has led many studies for identifying, designing, and synthesizing new antimicrobial agents.The aim of this study was to evaluate antimicrobial effects of some synthesized potassium dithiocarbazinate derivatives against 6 Gram-negative and 4 Gram-positive bacteria as well as 2 molds and 1 yeast. Potassium salts of dithiocarbazinic acids w...

(1,4,5-Triphenylimidazol-2-yl-thio)butyric acid hydrazide (3) was obtained via alkylation of 1,4,5-triphenylimidazol-2- thiol (1) with ethylbromobutyrate, followed by addition of hydrazine hydrate. Treatment of acid hydrazide 3 with carbon disulfide in an ethanolic potassium hydroxide solution gave the intermediate potassium dithiocarbazinate salt, which was cyclized to 4-amino-5-[(1,4,5-triphe...

atp-sensitive potassium (katp) channel openers have a relaxation effect due to the lower cellular membrane potential and inhibit calcium influx. there has been considerable interest in exploring katp channel openers in the treatment of various diseases such as cardiovascular, cerebrovascular, and urinary system disease and premature labor. the purpose of this study was to synthesize 3,3,6,6-tet...

irrigation with distillery effluent, besides influencing crop yield, may have considerable impact on physical properties of soil because of its high salt and organic carbon contents. this experimental study was conducted to evaluate the effect of distillery effluent on hydraulic conductivity of a sandy loam alluvial soil and compare the effect of inorganic salts of potassium (k) with that of di...

nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °c. the reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). the difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. it was found that both the yield and purity of the product is better starting with potassium sulp...

abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....

Increasing the area of arable oilseed land, particularly rapeseed, and the important role of potassium in yield and oil content, especially in calcareous and high pH soils, need to more knowledge about plant nutrition requirement. In this study, the effect of sources and different levels of potassium fertilizers on some quality and quantity characteristics on canola yield were assessed by combi...

the present research designed to evaluate the effects of foliar application of methyl jasmonate (meja), salicylic acid (sa) and potassium sulfate on improving fruit quality and photosynthesis system. ten treatments include: sa (0.3, 0.6 and 0.9 mm), meja (0.5, 1 and 2 mm), potassium sulfate (0.5, 1 and 1.5%) and distilled water (control) were sprayed on pomegranate trees 2 and 7 weeks after ful...
