Four amidine NR2B-selective NMDA receptor antagonists, N-( 2-methoxy benzyl) -3-phenyl-acrylamidine, N-[diduterio(2-methoxyphenyl) methyl]-3-phenyl-acrylamidine, N-benzyl-3-phenyl-acryl amidine and N-[diduterio(phenyl)methyl]-3-phenyl-acrylamidine, all fourlabeled with carbon-14 in the 1-position, have been synthesized as part of 5-step sequence fromBa14CO3.
The present paper describes the synthesis of two Azo-Schiff base named (2-(((2-aminophenyl)imino)methyl)-6-ethoxy-4-((Z)-phenyldiazenyl) phenol, 2-((Z)-((4-aminobutyl)imino)methyl)-6-ethoxy-4-((Z)-phenyldiazenyl)phenol) by diazotization reaction synthesized (3-Ethoxy-2-hydroxy benzaldehyde) with aniline compound to gave Al- Azo – aldehyde and reacted (O-phenylenediamine or1,4-butanediamine) bas...
DPPH radical scavenging reactions of protocatechuic acid and its methyl ester were investigated in various solvents. In alcoholic solvents, methyl protocatechuate rapidly scavenged more than four equivalents of the radical, whereas approximately two equivalents were consumed in aprotic solvents. Methyl, ethyl, butyl, isopropyl, and tert-butyl protocatechuates were examined for their DPPH radica...
In contrast to all previous results with many derivatives of 4-dimethylaminoazobenzene, the ingestion by the rat of 3-methoxy-4-aminoazobenzene or its N-monomethyl or N,N-dimethyl derivatives was found to induce high incidences of squamouscell carcinomas of the ear duct. $-Methoxy-4-aminoazobenzene also induced low incidences of adenocarcinomas in the small intestine and mammary gland. In addit...
We have prepared and characterised a series of side-chain liquid crystalline homopolymers terpolymers containing different azobenzene derivatives (RAzB), sulfonic groups (2-acrylamido-2-methyl-1-propanesulfonic acid, AMPS), methyl(methacrylate) (MMA), as monomeric units. evaluated the effect para-substitutes 6-(4-azobenzene -4′-oxy)hexyl methacrylate, at side chains, OCH3, NO2 H, on phase behav...
four amidine nr2b-selective nmda receptor antagonists, n-( 2-methoxy benzyl) -3-phenyl-acrylamidine, n-[diduterio(2-methoxyphenyl) methyl]-3-phenyl-acrylamidine, n-benzyl-3-phenyl-acryl amidine and n-[diduterio(phenyl)methyl]-3-phenyl-acrylamidine, all fourlabeled with carbon-14 in the 1-position, have been synthesized as part of 5-step sequence fromba14co3.
Multiwalled carbon nanotubes (MWCNTs) have been functionalized with -SO3H groups using new three steps chemical routes. Firstly, OH groups have been attached to CNT surfaces through a radical reaction. The second step involves converting the hydroxyl groups into the oxide one and last step included the attachment of –SO3H groups on the MWCNTs surfaces in the presence of 1-butyl-3-methyl imidazo...
tyrosinase is a multifunctional oxidase that is widely distributed in nature. it is a key enzyme in melanin biosynthesis and is involved in determining the color of mammalian skin and hair. in addition it is responsible for the undesirable enzymatic browning that occurs in plant-derived foods, limiting the shelf -life of fresh-cut products with the resultant economic loss. in recent years ther...

Plutella xylostella cause considerable harm to the production of broccoli, Chinese cabbage, cabbage and cauliflower. The control P. is mainly performed using commercial insecticides, which have even led emergence resistant populations. Two easily available natural products found in different plants essential oil, thymol eugenol, stand up as possible novel agents this pest. In work a series alky...
