In this paper, synthesis and antimicrobial properties of cationic dye were investigated. 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide was reacted with 1-bromobutane as the alkylating agent and a cationic dye was obtained. The final product was purified by column chromatography method. The chemical structure of the novel cationic dye and its intermediates was chracterisized by using F...

In the present study, two new organic dyes based on indigo were prepared and used as sensitizers in dye-sensitized solar cells. To this end, indoxyl was utilized as the electron donor and cyanoacrylic acid as the electron acceptor anchoring groups. These dyes together with their corresponding intermediates were purified and characterized by FTIR, 1HNMR, 13CNMR, elemental analysis and UV-Visible...

Fast-flow spherical homogeneous agarose beads were prepared by an emulsification method, and were cross-linked and activated by repeated treatment with allylbromide and bromine/water, followed by alkali. Bis(2-aminopyridyl)dioxime (APD) was synthesized by the reaction of 2-aminopyridine, and dichloroglyoxime and characterized by melting-point as well as IR, 1HNMR, 13CNMR and MS spectroscopies. ...

Bioactive compounds (BACs) from plants provide unlimited opportunities for pharmaceuticals and natural agrochemicals development due to vast diversity of secondary compounds. Successful identification and development of natural products from plants necessitates a standard and integrated approach to screen compounds which aids in determination of dose response activity. We examined Peperomia pel...

This study investigated the possible antidiabetic role and therapeutic crucial action of the saponin fractions of the ethanolic extract of areal parts of the medicinal plant Anabasis articulata compared to currently available antidiabetic drug gliclazide (diamicron) against diabetic complications induced tissue injury in rats. Fractionation of hydro alcoholic extract from the aerial parts of An...

Sarcophrynium brachyatachys, commonly known as Yoruba soft cane or the praying plant, is traditionally used for packaging food items. Only a few natives recognize usefulness of leaves treatment cough and bronchitis in herbal medicine. This study was designed to isolate characterize bioactive component. Successful percolation carried out with 96 percent ethanol get crude extract. Afterwards, fra...

In the present study, a series of new hydrazone and sulfonamide derivatives of 1,2,4-triazole were synthesized. Initially three 4-substituted-5-(2-pyridyl)-1,2,4-triazole-3-thiones ZE-1(a-c) were treated with ethyl chloroacetate to get the corresponding thioesters ZE-2(a-c), which were reacted with hydrazine hydrate to the respective hydrazides ZE-3(a-c). The synthesized hydrazides were condens...

Purpose: The article is aimed to synthesize,characterize and screening the biological activity of a series of Synthesis of 1-(2-(3-(3-chloro-1-(4-substituted phenyl)-4-tetrazole-2-yl)-1H-indol-1-yl)acetyl)-4-(2-(4substituted phenyl)hydrazono)-3-(trifluoromethyl)-1H-pyrazol-5(4H)-one 4(a-f). Indole-3-carbaldehyde and chloro ethyl acetate were dissolved in DMF. To this reaction mixture anhydrous ...
