4-chloromethyl styrene (cms) was copolymerized with different monomers such as methyl methacrylate (mma), methyl acrylate (ma), 2-ethylhexyl acrylate (eha) by free radical polymerization method at 70 ±1°c using a,a'-azobis(isobutyronitrile) (aibn) as an initiator. the copolymer compositions were obtained using related 1hnmr spectra and the polydispersity of the copolymers were determined using ...

In a search for new leads towards potent antibacterial agents, an array of novel N-[2-(3 ́chloro-2 ́-oxo-4 ́-substitutedaryl-1-azetidinyl)-1-3-thiazol-4-yl]diphenylamine 4(a-e) and N-[2-(2 ́substitutedaryl-4 ́-oxo-1 ́3 ́-thiazolidin-3 ́-yl)-1,3-thiazol-4-yl]diphenylamine 5(a-e) have been synthesized from N-(2-substitutedbenzylidenylimino-1,3-thiazol-4-yl)diphenylamine 3(a-e). Structure of all the synth...

Five novel 3-alkyl-4-phenylacetylamino-4,5-dihydro-1H-1,2,4-triazol-5-ones (2) were synthesized by the reactions of 3-alkyl-4-amino-4,5-dihydro-1H-1,2,4-triazol-5-ones (1) with phenylacetyl chloride and characterized by elemental analyses and IR, 1HNMR, 13C-NMR and UV spectral data. The newly synthesized compounds 2 were titrated potentiometrically with tetrabutylammonium hydroxide in four non-...

In this paper we sensitized three free-metal azo days Dye 1, Dye 2 and Dye 3 based on 1,8-naphthalimide with n-propyl as the electron donor group. We used sulfonic acid and hydroxyl substituents as the electron acceptor anchoring group in synthesized dyes. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions and characterized by different techniques...

In present research work, anion exchange membranes based on quaternized polysulfone with ammonium cation moieties (QAPSF) were prepared by chloromethylation, amination and alkalization. The chloromethylated polysulfone were characterized by 1HNMR spectroscopy and functionalization degree was determined according to peak area integration. Ion transport properties (ionic conductivity, ion exchang...

In present research work, homogeneous anion exchange membranes based on polysulfone (QAPSFs) were prepared via chloromethylation, amination and alkalization. In amination step, trimethylamine and N,N,N',N'-tetramethyl-1,6-hexanediamine were used as amination and crosslinking agents, respectively. The chloromethylated polysulfone was characterized by 1HNMR spectroscopy and chloromethylation degr...

HIE-124 is the new member of ultra-short acting hypnotics drug family. In this research, thiadiazole can act as the bio-isosteric replacement of thiazole in synthesized compounds as HIE-124 derivatives. HIE-124 drug, in which the heterocyclic thiazole ring replaced to thiadiazole, will be presented. Thiadiazolodiazepines were synthesized by a two-step reaction starting from the amino thiadiazol...

OBJECTIVES Antimicrobial properties of medicinal plants and plant parts such as flowers, roots, fruits, seeds and oils are being used to cure some chronic and acute diseases throughout the world. In the present study, an attempt has been made to isolate and identify the antibacterial compound present in the leaves of the Cassia auriculata. MATERIALS AND METHODS A preliminary screening of anti...
