Hong Sik Yoo et al.
Journal of toxicology and environmental health. Part A, 78(1), 32-49 (2014-11-27)
Trichloroethylene (TCE) is a well-known environmental and occupational toxicant that is classified as carcinogenic to humans based on the epidemiological evidence of an association with higher risk of renal-cell carcinoma. A number of scientific issues critical for assessing human health
Brian M Wagner et al.
Journal of chromatography. A, 1489, 75-85 (2017-02-19)
To facilitate mass transport and column efficiency, solutes must have free access to particle pores to facilitate interactions with the stationary phase. To ensure this feature, particles should be used for HPLC separations which have pores sufficiently large to accommodate
Tse-Hong Chen et al.
Analytical chemistry, 91(4), 2805-2812 (2019-01-22)
The synthesis of antibody-drug conjugates (ADCs) using the interchain cysteines of the antibody inherently gives a mixture of proteins with varying drug-to-antibody ratio. The drug distribution profiles of ADCs are routinely characterized by hydrophobic interaction chromatography (HIC). Because HIC is
Use of structure-activity relationships for probing biochemical mechanisms: glutathione transferase zeta conjugation of haloacids.
P D Swartz et al.
Advances in experimental medicine and biology, 500, 23-31 (2002-01-05)
Roberto Morales-Cerrada et al.
Chemistry (Weinheim an der Bergstrasse, Germany), 25(1), 296-308 (2018-09-20)
Thermal decarbonylation of the acyl compounds [Mn(CO)5 (CORF )] (RF =CF3 , CHF2 , CH2 CF3 , CF2 CH3 ) yielded the corresponding alkyl derivatives [Mn(CO)5 (RF )], some of which have not been previously reported. The compounds were fully
N Illy et al.
Comptes rendus des seances de la Societe de biologie et de ses filiales, 175(2), 242-246 (1981-01-01)
Our experiments were carried out in normal and streptozotocin-diabetic rats. The effects of sodium difluoroacetate (DFA) at the dose of 40 mg/kg daily were studied on the blood and retinal lactate levels; these effects were compared to those of an
Tetrahedron Letters, 48, 3251-3251 (2007)
The many roles for fluorine in medicinal chemistry.

Chemistry (Weinheim an der Bergstrasse, Germany), 8(13), 2917-2922 (2002-12-20)
Ethers of trifluoroacetaldehyde hemiaminals can undergo dehydrofluorination under basic conditions to provide ethers of difluoroketene hemiaminals. The latter behave as equivalents of difluoroacetamide or difluoroacetate anions towards various electrophiles, yielding a range of difluoromethylcarbonyl products.
Ute Dorgerloh et al.
Molecules (Basel, Switzerland), 24(6) (2019-03-17)
The concentrations of difluoroacetic acid (DFA) and trifluoroacetic acid (TFA) in rainwater and surface water from Berlin, Germany resembled those reported for similar urban areas, and the TFA/DFA ratio in rainwater of 10:1 was in accordance with the literature. In
Hoffman B M Lantum et al.
Toxicological sciences : an official journal of the Society of Toxicology, 70(2), 261-268 (2002-11-21)
Dichloroacetic acid (DCA), chlorofluoroacetic acid (CFA), and difluoroacetic acid (DFA) are inhibitors of pyruvate dehydrogenase kinase. DCA is used for the clinical management of congenital lactic acidosis. Glutathione transferase zeta (GSTZ1-1) catalyzes the biotransformation of DCA and CFA, and DCA
J M Dalstein et al.
Comptes rendus des seances de la Societe de biologie et de ses filiales, 174(5), 821-825 (1980-01-01)
In the anesthetized rat, the intraperitoneal injection of 40 mg/kg sodium difluoroacetate (DFA), an activator of the pyruvate dehydrogenase, counteracted the hyperlactatemia induced by a high dose of phenformin (40 mg/kg) injected concomitantly. In the normal conscious dog, the administration
J N Commandeur et al.
Biochemical pharmacology, 37(23), 4495-4504 (1988-12-01)
The biotransformation and the hepato- and nephrotoxicity of the mercapturic acids (N-acetyl-1-cysteine S-conjugates) of three structurally related 2,2-difluoroethylenes were investigated in vivo in the rat. All mercapturic acids appeared to cause nephrotoxicity, without any measureable effect on the liver. The

Hydroxypropyltrimethyl ammonium chitosan halogenated acetates were successfully synthesized from six different haloacetic acids and hydroxypropyltrimethyl ammonium chloride chitosan (HACC) with high substitution degree, which are hydroxypropyltrimethyl ammonium chitosan bromacetate (HACBA), hydroxypropyltrimethyl ammonium chitosan chloroacetate (HACCA), hydroxypropyltrimethyl ammonium chitosan dichloroacetate (HACDCA)
Youngwook Park et al.
The journal of physical chemistry letters, 9(15), 4282-4286 (2018-07-13)
Chemical reactions are extremely difficult to occur in ice at low temperature, where atoms and molecules are frozen in position with minimal thermal energy and entropy. Contrary to this general behavior, certain weak acids including fluoroacetic acids dissociate spontaneously and
