Formation of mercapturic acids from acrylonitrile, crotononitrile, and cinnamonitrile by direct conjugation and via an intermediate oxidation process.

P J van Bladeren et al.

Drug metabolism and disposition: the biological fate of chemicals, 9(3), 246-249 (1981-05-01)

After administration of acrylonitrile, crotononitrile and cinnamonitrile to rats, two types of mercapturic acids were isolated from urine and identified by mass and NMR spectroscopy as N-acetyl-S-(2-cyanoethyl)-L-cysteine (I) and N-acetyl-S-(2-hydroxyethyl)-L-cysteine (II) (methyl-substituted in the case of crotonitrile and phenyl-substituted in

The spectroscopy and photochemistry of quinioline structural isomers: (E)- and (Z)-phenylvinylnitrile.

Deepali N Mehta-Hurt et al.

The Journal of chemical physics, 143(7), 074304-074304 (2015-08-25)

In Titan's atmosphere, photochemical pathways that lead to nitrogen heteroaromatics may incorporate photoisomerization of their structural isomers as a final step. (E)- and (Z)-phenylvinylnitrile ((E)- and (Z)-PVN, C6H5-CH=CHCN) are structural isomers of quinoline that themselves possess extensive absorptions in the

Direct oxidative coupling of benzenes with acrylonitriles to cinnamonitriles catalyzed by Pd(OAc)(2)/HPMoV/O(2) system.

Yasushi Obora et al.

Organic & biomolecular chemistry, 8(18), 4071-4073 (2010-07-24)

A facile direct synthesis of cinnamonitriles from acrylonitriles and benzenes is successfully achieved by using Pd(OAc)(2)/HPMoV/O(2) catalyst system via the direct C-H bond activation of benzenes using molecular oxygen as a terminal oxidant.

Use of achiral/chiral SFC/MS for the profiling of isomeric cinnamonitrile/hydrocinnamonitrile products in chiral drug synthesis.

A J Alexander et al.

Analytical chemistry, 78(11), 3835-3838 (2006-06-02)

A directly coupled achiral/chiral SFC/MS method has been developed for the profiling of a three-step stereoselective synthesis of cinnamonitrile and hydrocinnamonitrile intermediates. Semipurified reaction mixtures were screened in one step to determine the diastereomeric/enantiomeric composition of the final product as

Synthesis and use of an in-solution ratiometric fluorescent viscosity sensor.

Derek Fischer et al.

Nature protocols, 2(1), 227-236 (2007-04-03)

A procedure for the synthesis of a ratiometric viscosity fluorescent sensor is described in this protocol. The essential requirement for the design of this sensor is the attachment of a primary fluorophore that has both a viscosity-independent fluorescence emission (coumarin

Reversible targeting of noncatalytic cysteines with chemically tuned electrophiles.

Iana M Serafimova et al.

Nature chemical biology, 8(5), 471-476 (2012-04-03)

Targeting noncatalytic cysteine residues with irreversible acrylamide-based inhibitors is a powerful approach for enhancing pharmacological potency and selectivity. Nevertheless, concerns about off-target modification motivate the development of reversible cysteine-targeting strategies. Here we show that electron-deficient olefins, including acrylamides, can be

Fluorogenic surrogate substrates for toluene-degrading bacteria--are they useful for activity analysis?

Susanne Günther et al.

Journal of microbiological methods, 70(2), 272-283 (2007-06-15)

Cultivated bacterial toluene degraders use one or several of four described pathways for the aerobic degradation of this priority groundwater contaminant. To be able to identify un-cultivated toluene-degrading bacteria within enriched or natural consortia, we attempted to develop a set
