trans-Methyl styryl ketone (MSK; trans-4-phenyl-3-buten-2-one) is a beta-unsaturated ketone that has a wide range of uses in industry, as well as consumer products. MSK does not appear to be overtly toxic in animal models, however, it has been shown to be mutagenic in several in vitro assays after S-9 activation. In this study experiments were conducted to characterize MSK absorption, distribut...

The amino acid glycine is involved not only in protein formation but in t,he synthesis of glutathione, creatine (l), and the protoporphyrin of hemoglobin (2). However, the mechanism by which the animal organism forms glycine is cluite obscure. It has been generally considered that the “nonessential” amino acids are synthesized from a-keto acids either by amination with ammonia or by transaminat...

in this paper, the structural properties of c20 and c12b8 fullerene interacting with glycine based onthree active sites of glycine and one c atom or one b atom in c12b8 were analyzed through thedensity functional theory. it was found out that the binding of glycine to c12b8 generated a complex.our results were extremely relevant in order to identify the potential applications of functionalizedc...

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.

low phosphorous (p) availability in soils limits production of soybean [glycine max (l.) merr.] around the world. this study was conducted to determine whether exogenous expression of the rice (oryza sativa l.) phosphates transporter gene ospt2 would increase inorganic phosphates (pi) acquisition and improve yield in transgenic soybean. cotyledonary-node explants of the soybean were inoculated ...

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...

reaction between aromatic aldehydes and 3–methyl-1-phenyl-2-pyrazoline-5-one catalyzed by nano-sio2/hclo4 in water under reflux provided a simple and efficient route for the synthesis of 4-((5-hydroxy-3-methyl-1-phenyl-1h-pyrazol-4-yl)(aryl)methyl)-3-methyl-1-phenyl-1h-pyrazol-5-ol derivatives in high yields.

The preparation of a new succinimidyl ester agarose derivative (SEPE-Agarose) is described. This agarose derivative can be used for covalently linking proteins and other ligands containing amino groups to agarose via phenyl ester linkages that can later be broken under mild conditions which should not alter other groups which may be present in proteins such as cystinyl residues and glycosyl res...
